Playback of decrypted channels (via dvbapi) broken by d07536b89646bbff3b9a0b08029609da7ce797e3

tkurbad commented 11 years ago

Hi Alex,

I just did a major upgrade on my VDR/XBMC box and it turned out that with commit d07536b89646bbff3b9a0b08029609da7ce797e3 your xvdr and manio's dvbapi plugin stopped playing well together.

Most of my encrypted DVB-C channels lead to intermittent or immediate crashes of VDR. If I go back one commit, everything's fine.

How should we proceed?

Best, Torsten

pipelka commented 11 years ago

Does this happen on HD or SD channels ? Even for both types ?

tkurbad commented 11 years ago

Since I only have a Pay-TV subscription for HD channels, the only thing I can tell you for sure is that it's happening on encrypted HD channels. The FTA channels are all fine, btw, SD and HD alike.

pipelka commented 11 years ago

It seems strange to me that only encrypted channels are affected. Technically there isn't any difference to the plugin at all.

tkurbad commented 11 years ago

Yeah, I thought so, too. But there seems to be something "wrong" with the encrypted ones, nonetheless.

If you have no objections, I'd like to record a snippet on one of the affected channels for you to analyze. Also, it would be interesting to know, if a record taken with the "working" version of xvdr can be played back with the newer version... Perhaps I'll try that first and let you know about the results.

tkurbad commented 11 years ago

Okay, here we go for some more confusion:

Not all channels are affected, some play fine even with git HEAD
If I record one of the broken channels by other means, e.g. vdradmin, VDR first "hickups", i.e. is restarted by the watchdog and produces an empty .ts file. In the second (automatic) attempt, recording works. This seems to be true, regardless of xvdr version.
Everything that got recorded can be viewed properly on all versions of the plugin.
Furthermore, if I view one of the broken channels on d07536b89646bbff3b9a0b08029609da7ce797e3 the first few frames stutter, then everything runs smoothly.
I disabled all plugins aside from dvbapi, svdrpservice and xvdr to run those tests to try to eliminate side effects.

What else could I check?

pipelka commented 11 years ago

There are to opportunities:

you run VDR inside a debugger (gdb) and check where it crashes
you provide a recording of a channel that causes a crash

What's suspicious to me is that VDR gets restarted (obviously crashes) on the first attempt of a recording.

tkurbad commented 11 years ago

I'll try the gdb approach.

Can you give me some instruction on how to produce a trace there that's valid for you to review?

pipelka commented 11 years ago

First make sure that your VDR compiler flags (Make.config) have debug information enabled (-O2 -g).

I have a script (runvdr.debug) that starts VDR within the debugger (please change the paths to match your setup):

#!/bin/sh
gdb -d [path_to_xvdr_sources] --args ./vdr -L /opt/vdr1.7/lib -c /etc/vdr -l 3 --localedir=/opt/vdr1.7/locale \
    -P"dvbapi -B0 -B1" \
    -P"xvdr"

Start the debug session and wait until it segfaults. Then do a backtrace:

./runvdr.debug
(gdb) run
(gdb) backtrace

That should give enough information to find the bug (hopefully).

Here's the backtrace:

What's strange is the "Reading symbols from /usr/bin/vdr...(no debugging symbols found)...done.", although I compiled with "debug" use flag which should add "-g" to CFLAGS. I'll try to correct that and come up with another backtrace.

Now I have a better one (I think):

What do you make of it?

pipelka commented 11 years ago

Please pull the branch "tkurbad" and check if it fixes the problem.

tkurbad commented 11 years ago

Not entirely. There is still at least one "problem" channel that works for about 1 second (at most) and then crashes VDR. Should I do another backtrace with the new branch?

pipelka commented 11 years ago

Yes. Please. But there is still something wrong with debug information. The trace should contain the source and linenumbers of the xvdr plugin. Did you recompile the plugin with debug information ?

tkurbad commented 11 years ago

Yes, I compiled with "-g". I'm compiling again now - this time without using distcc. ;-)

Backtrace follows...

tkurbad commented 11 years ago

Do I have to give CFLAGS besides "-g" for debugging to work properly?

Here's the new backtrace:

tkurbad commented 11 years ago

Just to be clear: The -d option of gdb has to point to source-root of your plugin, i.e. the directory where Makefile etc. reside, right?

pipelka commented 11 years ago

Yes. On my system debug information is only created if i start the build process from the root of the VDR directory. Then it builds all plugins with the flags defined in "Make.config".

You can check if debug information is available with:

# objdump -g /usr/lib64/vdr/plugins/libvdr-xvdr.so.1.7.41 | grep "demuxer_H264.c"

It should output something like:

 <73cc>   DW_AT_name        : (indirect string, offset: 0x17a0): src/demuxer/demuxer_H264.c

tkurbad commented 11 years ago

Ah, I see. So, I'll try and do a manual build outside the Gentoo ebuild system.

tkurbad commented 11 years ago

Can you please post a debug enabled Make.config for reference?

pipelka commented 11 years ago

Here are the top lines of my current config:

### The C compiler and options:
CC       = gcc
CFLAGS   = -O2 -g  -Wall
CXX      = g++
CXXFLAGS = -O2 -g  -Werror=overloaded-virtual -Wno-parentheses
# Use 'make M32=1 ...' to build a 32-bit version of VDR on a 64-bit machine:
ifdef M32
CFLAGS   += -m32
CXXFLAGS += -m32
endif

tkurbad commented 11 years ago

Yeah, I can see the problem: The Gentoo ebuilds eliminate those lines and just export the necessary shell variables. I just added the missing lines now and run a manual 'make' inside VDR's source root. Next thing I'll do the same for the xvdr plugin and try a new debug run.

tkurbad commented 11 years ago

Well, I'm an idiot. Debugging symbols are well there in the first place. But the Gentoo ebuild system strips them upon install. ;-)

I'm just running a new build of vdr and xvdr with FEATURES="nostrip"...

tkurbad commented 11 years ago

As the old wisdom says: "As soon as you do it right, it works" :-)

Here's another backtrace with proper debug symbols:

Very strange.

Please do a:

(gdb) select-frame 4
(gdb) print length
(gdb) print o
(gdb) print nal_len

in the debugger (after the crash).

tkurbad commented 11 years ago

(gdb) select-frame 4

(gdb) print o
$2 = 25
(gdb) print nal_len

tkurbad commented 11 years ago

On a second crash (right after switching to one of the "problem" channels), I get:

(gdb) select-frame 4
(gdb) print length
No symbol "length" in current context.
(gdb) print o
No symbol "o" in current context.
(gdb) print nal_len
No symbol "nal_len" in current context.
(gdb)

The backtrace to that one looks like this:

Oh. Sorry. You have to select the frame containing "cParserH264::ParsePayload". That isn't always 4.

That was on another channel (SyFy HD) that ran fine for almost a minute and then crashed.

Here's an interesting one (nal_len = 0) - VOX HD:

Maybe there's a bug in vdr itself, too?

pipelka commented 11 years ago

All these bugs are symptoms of a buffer overrun. Please repull. Maybe everything is correct now.

tkurbad commented 11 years ago

Thanks so much, that seems to have done it! All HD channels I tried after the last commit start up immediately and seem to run smoothly.

Just to be sure, I'd suggest I let the most problematic (Fox HD) run for about an hour and report back with a (hopefully) final statement. Okay?

pipelka commented 11 years ago

Ok. It's really odd that this bug never surfaced before, ...

tkurbad commented 11 years ago

Fox HD running for about 45 minutes without problems and/or interruptions, even for 2 simultaneously connected clients. I think we can safely assume that the bug is fixed. :-)

It's really odd that this bug kept unnoticed for several days - and even more that it didn't affect all H264 channels...

Anyway, thanks a lot for the quick fix and keep up the good work!

pipelka commented 11 years ago

I just found that this "fix" introduces a rather nasty bug. I'll try to iron that out and will ask you to check it again. This won't happen today. Thanks for your help.

tkurbad commented 11 years ago

No problem. I'll watch this space for news and test requests.

pipelka commented 11 years ago

@tkurbad Could you please recheck if the latest version still works for you ?

tkurbad commented 11 years ago

I did a short test with about 8 different channels - all seem to work flawlessly. Also I recorded a snippet and realized that the "hickup" upon recording start seems to have gone.

Nice work!

pipelka commented 11 years ago

Great. I'll push the fix into master. Thanks for checking that.
