DVB playback broken #239

Closed ghost closed 9 years ago

ghost commented 11 years ago

Someone told me that someone told him that dvb playback was far worse than with mplayer/mplayer2. I don't know details, and I can't test the DVB code, so more information would be nice.

If anyone actually wants to use DVB, and experiences problems, please tell.

This is probably in part caused by dropping the internal TS demuxer, which was default for DVB.

Hello, I tried to use mpv(-0.1.5) and dvb, but after 1-10seconds the video starts to hang, or gets partically broken, NOTE: it is not related to a specific channel, I tried 5 different channels and its always the same. I hope the following output+comments helps a bit:

buscher commented 11 years ago

I tried stream-dump, but the result was always perfectly playable with mpv/mplayer/mplayer2

however the with --stream-capture its different: http://buschinski.de/misc/mpv-stream-capture.out

it gives different results with mpv/mplayer/mplayer2

I would say mplayer(1) performes the best here.

ghost commented 11 years ago

Thanks for reporting! The stream capture is especially useful.

Playing the sample normally, it works fine until about 65%, then something goes wrong. Even with MPlayer (which uses the builtin ts demuxer, not libavformat) shows a corrupted frame. But MPlayer goes on, while mpv gets stuck.

If I play it with --no-correct-pts, playback seems relatively acceptable, though. Can you try whether adding this option improves it?

buscher commented 11 years ago

Yes, for the testfile this option helps a lot.

But it doesn't solve the main dvb problem, it only seems to minimize/delay the stutter/brokenness if I run mpv -v --no-correct-pt dvb://ProSieben

And again, if I just use mpv --dump-stream=foo.out dvb://ProSieben, and watch it with mpv (w/o options) it always works fine. And also fine if I directly watch the dvb with mplayer1/2

ghost commented 11 years ago

I'm out of ideas for now. Maybe it has something to do with how much libavformat is reading, and maybe it's somehow not correctly in lock-step. It's possible that moving the demuxer into its own thread will help, but it hasn't happened yet anyway.

Can you test mpv git revision 3e7d483ac89289f613? It's some months old, and it's the last commit before the internal ts demuxer was removed. I would hope that behaves same as mplayer/mplayer2.

buscher commented 11 years ago

git clone https://github.com/mpv-player/mpv.git && cd mpv && git checkout 3e7d483ac89289f613 && ./configure && make -j5 && ./mpv -v -vo vdpau dvb://ProSieben

and yes, it works fine, so the same as mplayer/mplayer2.

with a lot of (by -v caused) log output like: COLLECT_SECTION, start: 64, size: 184, collected: 184 SKIP: 0+1, TID: 0, TLEN: 49, COLLECTED: 184

NOTE: because of the performance I had to add -vo vdpau here, but thats what current mpv automagically does anyway and I guess its not related to the real problem.

I'm having problems to play dvb streams as well. This is the output of the versions from the arch linux repo:

Hm, I have an idea how to debug this further.

Use mpv dvb://whatever --stream-dump=out.dat. This will write the raw stream received from the DVB API into out.dat. I'm not sure how high the bitrate is when you should stop the dump (it should go on forever, as long as DVB data is received). You probably need to retry if the stream turns out too small.

Then try to play the created file with various software, including mpv and mplayer. Report your findings, and if they're interesting enough, upload the file.

I still don't know why or what is failing here, though.

If you're interested in the video file, just let me know!

buscher commented 10 years ago

just a quick notice from my side, I moved and I no longer have dvb(-s) access, so sorry I can not provide any useful information :(

ghost commented 10 years ago

@dln11: the file is probably too short, and libavformat thinks it can't detect the file format reliably.

jal-frezie commented 10 years ago

Hi, I am getting exactly these symptoms whether playing from the dvb-t device directly with mpv, or whether using another program to stream data from it to mpv via stdin. Playback always works OK if I save the data to file then play it with mpv, but the file must contain around 20 seconds worth of data before trying to play it! Could mpv be seeking too far ahead? Will be happy to provide any data I can get.

ghost commented 10 years ago

Could mpv be seeking too far ahead?

mpv itself probably doesn't seek, but it could be that libavformat tries to read too much of the stream to gather information. It also seems libavformat tries to seek sometimes while doing this, I'm not entirely sure. In any case, it has to do this, because transport streams contain no headers. But 20 seconds definitely sounds like too much.

Will be happy to provide any data I can get.

Post a log with the --msglevel=lavf=trace option set. Also helpful: upload such a problematic stream somewhere.

ghost commented 10 years ago

Another thing I just remembered... run with --vd-lavc-show-all. This option makes the video decoder return all frames, even if they're damaged/incomplete. This could be important for fast stream start, because otherwise it will read data until a good frame is decoded.

dln11 commented 10 years ago

I solved the problem by exchanging the cable which I bought new because of this problem with another (shorter) cable.

bpaterni commented 10 years ago

Just thought I'd chime in and say that dvb streaming seems to have gotten a bit better. I'm not sure with what version exactly, but right now I happen to be using 0.6.0:

mpv 0.6.0 (C) 2000-2014 mpv/MPlayer/mplayer2 projects
 built on 2014-09-30T19:17:45
libav library versions:
   libavutil       54.3.0
   libavcodec      56.1.0
   libavformat     56.1.0
   libswscale      3.0.0
   libavfilter     5.0.0
   libavresample   2.1.0

With no non-default options (other than setting up audio output), dvb is now watchable, but it is not without a few hiccups. Though, as mentioned earlier in this bug, since what I'm seeing during a live dvb stream does not occur during playback of a --stream-dumped file, I've included the linked to output of mpv -v --msg-level=lavf=trace in a github gist

The first hiccup I see is after line 155 where mpv appears to stall for a few seconds before video is output to the screen (as opposed to mplayer2, where video is output rather instantaneously. Also note that running with --vd-lavc-show-all does not appear to speed up stream start). On normal output, mpv seems to stall here until it hits line 331 and after a few "Invalid frame dimensions 0x0" lines. Following these initial hiccups, video output of seems fine for a couple seconds until a few failed "Continuity checks" around Line 1754. At this point, the stream freezes for a couple seconds, but instead of a full hang, mpv seems to correct itself, and by the time frames begin drawing again, video is delayed by ~2 seconds to which mpv slowly begins to correct itself until Audio-Video is once again synced. After this correction, the steam is able to continue without any major issues.

Hopefully this message can help in improving mpv's dvb support.

ghost commented 10 years ago

To me it looks like this is a problem with libavformat's .ts demuxer (as I suspected from the start).

It reads about 5MB of data... and then wants to seek back to the start. Of course that's not going to work. Apart from that, try to use these options to reduce delay: --demux-lavf-analyzeduration=1 --demux-lavf-probesize=512000 (they also could lead to misdetection, though)

ghost commented 10 years ago

Also, can you try the stream-dump file by piping it to mpv? Like: cat dump | mpv -. You should see the same problems.

bpaterni commented 10 years ago

Hey wm4

It looks like those two options are instead named --demuxer-lavf-analyzeduration=1 and --demuxer-lavf-probesize=512000 for anyone wondering.

Otherwise, I can say these two options do make dvb stream startup a bit snappier than without. And it also looks like they alleviate somewhat the temporary video freeze (and delay) that occurs ~2 seconds into the stream.

However, it doesn't look like piping the stream dump to mpv reproduces the problems seen on a live stream either. cat dump | mpv - plays pretty much flawlessly aside from the first few broken frames of the captured stream.

ghost commented 10 years ago

Thanks, this was helpful. I was at first mystified by this, but then I focused on what could be different between dvb and pipe input. I may have found something and pushed some changes to git master, but it's quite likely it won't actually change anything.

bpaterni commented 10 years ago

Apologies for not posting an update right away. I'm not tracking git, but it looks like 0.6.1 was just released today, and fortunately it made its way into Debian unstable very quickly. :)

With 0.6.1 though, there doesn't seem to be much improvement with respect to DVB. Also as you had expected, I'm still unable to see the same effects when playing a stream dump via a supplied command argument or through a pipe. If it's at all helpful though, I've uploaded a sample stream dump to the first free file hosting site I could find anyway. Here's the link

ghost commented 10 years ago

The changes I made aren't in the releases.

bpaterni commented 10 years ago

Whoops! Sorry about that, wm4.

I have some time this weekend and checked out git master. TBH, while a few development packages were needed, the waf configure and build process did go rather smoothly. :) Though unless I'm mistaken, I'm afraid the feedback given in my last message still stands with mpv git-421bce0. I saw little change with regard to live DVB streaming (not sure if any changes were made there, but figured it should be stated anyway). Also, the problem remains unreproducible with playback of a stream-dumped file via pipe or command argument.

I don't know how helpful it would be, but I've provided another gist of output from mpv here

Much appreciation for your help so far in this bug, wm4. :)

jal-frezie commented 10 years ago

Not sure this is on topic, but when I found this problem, I tried a few other video player tools (mplayer, vlc...) and found similar problems with all of them! Does anyone know of one that works well? Might be something to do with a library they all use (ffmpeg?) --J

I still see that ffmpeg/libavformat thinks it can seek:

[lavf] mp_seek(0x7f9150dd1050, 0, 0)

....

but when I found this problem, I tried a few other video player tools (mplayer, vlc...) and found similar problems with all of them! Does anyone know of one that works well?

I heard tvheadend is good.

ghost commented 10 years ago

@bpaterni: can you maybe run mpv in gdb, and set a break point on this Cannot seek backward in linear streams! message, and then print a backtrace? Currently, this line is in stream/stream.c line 650 (git master). If you need help, I can provide step-by-step instructions.

bpaterni commented 10 years ago

I was able to get this backtrace, but it doesn't look like debian unstable contains any packages containing debugging symbols for libavformat. Hopefully these aren't too critical?...

ghost commented 10 years ago

Debugging symbols for libavformat would be useful. If everything else fails, maybe you can use https://github.com/mpv-player/mpv-build ?

ghedo commented 10 years ago

it doesn't look like debian unstable contains any packages containing debugging symbols for libavformat

The package is called libav-dbg (or ffmpeg-dbg if you are using the ffmpeg libraries).

ghedo commented 10 years ago

Also, if you are using the official Debian package, you may also want to try the version in experimental (0.6.1-1+ffmpeg) which is built against ffmpeg.

bpaterni commented 10 years ago

The package is called libav-dbg

Wonderful! I should have been more thorough in my search, thanks ghedo! :)

The previous gist backtrace should now be updated.

ghost commented 10 years ago

On what mpv version is this based exactly? I can't find the git hash.

bpaterni commented 10 years ago

the current backtrace should be based off git-fa90415

ghost commented 10 years ago

Is the log you've posted from that version too? If not, repost the log please.

bpaterni commented 10 years ago

I'm afraid not. Here's a matching log

ghost commented 10 years ago

Thanks. Then I think we correctly signal libavformat that the stream is not seekable.

What absolutely doesn't make sense to me is that piping the stream dump (cat file | mpv -) doesn't expose this behavior.

tegularius commented 10 years ago

I had the same problem some time ago. It turned out to be a problem with ffmpeg, mplayer uses its own demuxer so it worked there. mpv however uses the ffmpeg demuxer. As far as I remember the ffmpeg demuxer runs out of data and handles reading from the device somehow badly. The problem disappered when I enlarged the kernel dmx ringbuffer [DVR_BUFFER_SIZE (100_188_1024) in dmxdev.h].

ghost commented 10 years ago

Not sure why that would help here...

From what I can see, the demuxer seems to make a seek request, which can never be handled. But it's not reproducible with pipes, so this behavior is mysterious to me.

olifre commented 9 years ago

Interesting bug report... I have one card with extremely good reception (DVB-S only, DVB-S2 does not work with that device on linux, due to a firmware bug, probably). With this card, I do not see the issues described here. I also do not see the strange mp_seeks, this is with ffmpeg 2.5.2 though.

It is also interesting to note that --demuxer-lavf-analyzeduration=1 alone has no effect at all for me, UNLESS also the PMT is available (this will soon be the case with my linked PR, I am just adding it - you need a VDR-style channel.conf though, as the classic mplayer channels.conf files do not contain the service_id). Probably the timing estimation does not work without PMT.

One more interesting finding, which I cannot explain: If I run mpv without any cache, the playback "hiccups" after a few seconds (5-10 seconds) once, then AV is desynchronized. If I use, say, --cache 200000, this does not happen.

Using both the large cache, the PMT-patch and the limited analyzeduration, playback start about 1 second after the tuning, which I consider almost instantaneous. I will add a gist sometime later when the PMT-patch is finished, maybe this can help to find out the reason why ffmpeg still uses the full analyzeduration. Maybe also a small mpv-cache should be default for stream_dvb (I think mplayer had that)?

Another change I did in my PR was to set the DMX-buffers (as also szap-s2 does it): https://github.com/olifre/mpv/commit/efcf6b1b68e9201a68f414165c71313113bfa14d#diff-928685972258d9895c12623b263b91fbR174 Does this change anything for somebody with problems?

I have a second DVB-S/S2 receiver card which probably has some hardware-defect. It generates bad packets every second on both Windows (original drivers) and Linux. With this, basically nothing helps, still I have the feeling that the demuxer in Windows handles the hiccups more gracefully.

I have also ordered a new DVB-S/S2 card which has native Linux support. I expect more bad packets even with good reception for DVB-S2 channels, so maybe I can reproduce some of the issues here then...

olifre commented 9 years ago

Here the gist, as promised: https://gist.github.com/olifre/ef52e947e97a2ecf8a8f This is with the patches from my PR #1409 applied. I let ffmpeg take the full analyzeduration.

Notice the AV-desynchronization after about 10 seconds of playback (on some audio-decoding error). This reproducibly happens for me after about 10-15 seconds.

Once I patch stream_dvb.c and add stream->streaming = true; thus activating mpv's cache, getting the following gist: https://gist.github.com/olifre/dd33eea08f0529f22bf6 that problem is gone. I see no desynchronizations or other playback issues after minutes.

I don't have an explanation either. Maybe it somehow happens because ffmpeg probing makes us read and buffer lots of data, which is then played without reading new data from the device, which could lead to a buffer overrun in the device/kernel? It's possible that the cache smoothes that out because it will keep reading from the device.

Maybe also a small mpv-cache should be default for stream_dvb (I think mplayer had that)?

I'm not opposed to this. I'm not sure if mplayer enabled the cache, but I'm pretty sure enabling the cache makes the dvb controls useless or even broken (or maybe not - the mplayer cache is forked, and I think the code for the DVB controls ignores this fact, which leads to interesting interactions).

olifre commented 9 years ago

I'm pretty sure enabling the cache makes the dvb controls useless or even broken (or maybe not - the mplayer cache is forked, and I think the code for the DVB controls ignores this fact, which leads to interesting interactions).

With DVB controls, you relate to the channel-switching (the dvb_channel property)? These act up very much in mpv without PMT indeed, I just tested it. On a channel-switch, it seemed that ffmpeg could not analyze any data successfully anymore... The fun-fact is that, with PMT being present and stream->streaming = true; it seems to work fine, also if I then set --no-cache. I will have a closer look tomorrow, but I think there is stream-emptying in stream_dvb (there is this funny line while(dvb_streaming_read(stream, buf, 4096) > 0); ).

Note that the "hiccup" also vanishes with --demuxer-lavf-analyzeduration=0.5, which matches your explanation quite well...

olifre commented 9 years ago

Seeing all this, it seems to me that enabling the cache in general helps with everything. However, even if the cache is enabled, it takes 5 seconds to switch from one channel to another / to initially show something. This is fully spent in the --demuxer-lavf-analyzeduration which is 5 by default.

I tried to find out which streams are causing this. It seems that, in addition to the Audio+Video+Teletext+Subtitle-streams, ffmpeg learns about more streams from PMT, an example: Stream #0:0[0x54], 0, 1/90000: Unknown: none ([6][0][0][0] / 0x0006) Stream #0:1[0x65], 125, 1/90000: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, left), 720x576 [SAR 64:45 DAR 16:9], 1/50, max. 15000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:2[0x66](deu), 208, 1/90000: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 256 kb/s Stream #0:3[0x67](mis), 208, 1/90000: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 192 kb/s Stream #0:4[0x68](deu), 127, 1/90000: Subtitle: dvb_teletext ([6][0][0][0] / 0x0006), 492x250 Stream #0:5[0x69](deu), 5, 1/90000: Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006) (hearing impaired) Stream #0:6[0x6a](deu), 152, 1/90000: Audio: ac3 ([6][0][0][0] / 0x0006), 48000 Hz, stereo, fltp, 448 kb/s Stream #0:7[0x816], 0, 1/90000: Unknown: none ([5][0][0][0] / 0x0005) Stream #0:8[0x87b], 0, 1/90000: Unknown: none ([11][0][0][0] / 0x000B) The time it spents to find out it can not identify the "none" streams is giving us this large delay. This is even though we do not open demuxer-FDs for them, so ffmpeg does not get any data there, but it still keeps looking in the stream of course.

I am not sure what is the best fix: Somehow, ffmpeg should be made aware that these streams are not interesting already when it probes the data (they might be EPG, some Smart-TV HTML-stuff, etc.). Is there a way to pass a "whitelist" of stream-ids to probe to ffmpeg? I am not aware of one (yet)... Of course lowering the analyzeduration for DVB by default could also work, but is not so nice (even 0.5 worked fine for me, but reception here is very good...).

Not that I know of...

Also, are you sure that's what's slowing it down?

I assume from this: https://gist.github.com/olifre/38da6096ab04bd88026b#file-gistfile1-txt-L1570 After taking the full analyzeduration, these three streams are the only streams ffmpeg complains about. Reducing analyzeduration to 0.5 still allows the "good" streams to be detected just fine (with good reception...). That gist (from a version with stream->streaming = true;) also contains one channel-switch, the tuning takes about 1-2 seconds here (this is still the DVB device with not-so-well drivers / unknown quality firmware, normally switching is faster), then ffmpeg takes 5 s analyzeduration, so overall switching time is something like 6-7 seconds.

So, I know nothing about dvb. Is the ts stream remuxed? By the kernel or by the hardware? How does the PMT get into the stream? (ffmpeg needs it; I hear .ts streams without PMT should be considered broken and unplayable, and the hacks in ffmpeg which allow it anyway are nothing but pure evil.) If the stream is remuxed at some point, why can't the "unwanted" streams not be dropped at this point? Could ffmpeg be made to recognize and ignore the unwanted streams properly?

I am afraid I am also no expert, but I believe this depends - at least for the "cheap" budget-type hardware, I think everything is done in the kernel, while full-featured hardware (which became more rare nowadays) the hardware handles almost everything, sometimes even including the decoding.

From the client-application point of view: For each PID to look at, a demuxer-fd is opened and a filter set up. Then, magically, a multiplexed TS appears on the logical /dev/dvb/adapter0/dvr0 device. In principle, one could also get the streams separately from the demux-FDs, but I never saw an application doing that.

Due to this logic, it also works to use an external application (e.g. szap-s2) to zap to a channel, keep it tuned, and then just call mpv /dev/dvb/adapter0/dvr0 to play back the TV stream.

How does the PMT get into the stream? (ffmpeg needs it; I hear .ts streams without PMT should be considered broken and unplayable, and the hacks in ffmpeg which allow it anyway are nothing but pure evil.)

The fun part is that the old code could not even get the PMT, since the PID of the PMT is not listed in the channels.conf (neither classic mplayer-style configs not vdr-vonfigs). The VDR-config contains a service_id, though. With the service_id, one can parse the PAT (which always has PID 0), look for the part corresponding to the service_id, from there find the PID for the PMT, and then also filter that one out. From this I am a bit confused as to how mplayer did / does that - the channels.conf does not contain the service-id, so apparently that only worked due to the ugly hacks...

As another fun fact, szap-s2 does add a filter for the PMT PID by default. So also the default with szap-s2 will be a stream without PMT.

If the stream is remuxed at some point, why can't the "unwanted" streams not be dropped at this point?

I believe they are already. I do not add filters for those PIDs, so their data should not be in the stream at all. If I use szap-s2 and do not add filters for the teletext-PIDs nor further audio tracks, ffmpeg still "knows" they should be there, but mis-recognizes them (e.g. real audio tracks as audio with 0 channels). I assume it reads some kind of header information (even without PMT / PAT being there) and from that deduces the stream-ids which should be there. Then it does not receive any data for those streams (since there is no filter letting them through), and as such can not guess the real format.

Could ffmpeg be made to recognize and ignore the unwanted streams properly?

I just had a look in some public channel-list for this channel, it seems these PIDs are really for HbbTV data (i.e. some HTML and control commands for Smart TVs to provide channel-specific Web-like content). Maybe ffmpeg could be made to recognize them, but the first problem is that I do not even know how it learns about their existence (I do not know too much about raw DVB streams to know which other header information there can be...).

Apparently I am wrong. I just disabled all filters, so the full stream arrives to ffmpeg (this is implemented via the pseudo-PID 8192). Then, it does NOT make use of the full analyzeduration, playback starts almost instantaneously. As "full stream" includes all programs on that transponder (5 video, 13 audio tracks...) this is not what one should really use. Still, it shows I must be missing something which ffmpeg expects to be present in the data. Let's see whether I can find out what that is....
