Vdr+xineliboutput+dshowserver =no joy #43

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

xine --verbose=3 "xvdr://127.0.0.1#nocache;demux:mpeg_block"

What is the expected output? What do you see instead?

The expected output is video on my tv :) like ffmpeg does
here is what xine says:

Im using vdr 1.7 + xine 1.1.14 + xineliboutput cvs
If i can rip the stream to a small file will you look at it?

oh well i couldnt wait, here it is, a testcase thats vdr independent is attached
mplayer plays just the music
xine with ffmpeg play audio+video
xine-1.1.14 + dshowserver plays audio and crashes after a while

i know that you dont have much time but i'd like to mention that many vdr users 
cant
wait to watch dvb-hd with their weak cpus ;)

update:
vanilla mplayer +ffh264 cant play because mplayer doesnt recognise the stream
mplayer + h264 hack from linuxtv iirc+ ffh264 => testclip plays
mplayer + h264 hack from linuxtv iirc+ dshowserver => testclip crashes
xine 1.1.14 +ffh264 => testclip works
xine 1.1.14 + dshowserver => audio for a while then crash

I'm experiencing the same problem with Vdr 1.7.0, xine-lib 1.1.15 (from HG) and
coreavc 1.7.0. I do get audio, but no image and a segfault after a 10 seconds 
or so.
Is there any debug info we can publish to help find the bug?

You mentioned on the homepage that xine hasn't been updated to support core 
1.7.0. Is
this still the case? If so, what differences are there between 1.5.0 and 1.7.0?

dshowserver plugin does not "see" BUF_FLAG_FRAME_END if the buffer carrying it 
is 
empty (= no video data). This results queuing all incoming data to buffer until 
it 
runs out of memory.

Try removing following lines from function dshowserver_decode_data in 
dshowserver.c :

    if( (int) buf->size <= 0 )
        return;

Thanks, that does seem to stop the first segfault. But now I get the following

it seems xine +dshowserver can play the test clip just by commenting out this 
empty
buffer check :).Ill check vdr later

Original comment by psofa.ps...@gmail.com on 28 Jul 2008 at 10:26

GoogleCodeExporter commented 8 years ago 
okay just tested vdr.Image comes at last but the dshow codec seems to be
reinitializing itself every 5-6 secs (i suppose a buffer underun because of the
removed check) and the video is kinda stuttering

on the testclip's channel it throws out tons of messages like "video_out: 
throwing
away image with pts 13183127 because it's too old (diff : 16083)." then after 1 
min 
it settles to okay performance

Original comment by psofa.ps...@gmail.com on 28 Jul 2008 at 11:13

GoogleCodeExporter commented 8 years ago 
to summarize:On one channel (which ffmpeg plays flawlessly) video appears like 
slow
motion and at 6-7 secs intervals dshowserver seems to reinitialize ( i suppose 
some
buffer overruns because of the slow motion).Ive watched the same channel with
mythtv+dshowserver perfectly (so the problem is in xine's demuxing or 
dshowclient code).
On the testcase's channel (which doesnt open with xineliboutput+ffmpeg correctly
either) coreavc needs sth like a minute to stabilize ("video_out: throwing
away image with pts 13183127 because it's too old (diff : 16083).") and play 
smooth

I need longer examples than what you've provided above.
I do see the same problems you describe, but the test stream is not long enough 
for
me to debug them sufficiently.
Something like zshare or gigashare is probably a better bet than trying to 
include it
directly in the ticket though.
