[BUG] seek problem with external ac3 stream
by Andrew Savchenko 05 Mar '10

05 Mar '10

Hello, I encountered the following problem with r26205 and a lot of earlier versions (though, I haven't perform regression test jet): When I use external ac3 audio stream (-audiofile option), I cannot seek in the movie properly: video is sought itself, but audio stream starts playing from the beginning after the seek operation. Moreover, video playback becomes becomes somewhat broken after seek: it seems that fps became lower. Interesting than just pausing (without seeking) works fine. Video itself is ok and can be played without any problems, as well as audio itself, but together they produce a problem. Such behaviour is valid for any video in any container, but external audio must be in AC3 format to reproduce a problem. There is nothing special or uncommon in mplayer's output, but it is provided at the and of e-mail just in case. Also I can upload a sample stream, but this bug is reproducible with any AC3 stream I have, so I can't see necessity of upload. *************************************************************************************************** $ ./mplayer -v -stop-xscreensaver -vo gl:lscale=1:cscale=1:yuv=3:osdcolor=0x0fefff /home/andrew/media/video/anime2/video/resident_evil/resident_evil_3_extinction_rus.mkv -audiofile /home/andrew/media/video/anime2/video/resident_evil/Resident\ Evil\ Extinction.ac3 MPlayer dev-SVN-r26205-4.3.0 (C) 2000-2008 MPlayer Team CPU: AMD Athlon(tm) XP 3200+ (Family: 6, Model: 10, Stepping: 0) CPUflags: MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE Creating config file: /home/andrew/.mplayer/config get_path('codecs.conf') -> '/home/andrew/.mplayer/codecs.conf' Reading /home/andrew/.mplayer/codecs.conf: Can't open '/home/andrew/.mplayer/codecs.conf': No such file or directory Reading /usr/local/etc/mplayer/codecs.conf: 117 audio & 241 video codecs Configuration: --language=en --enable-menu --enable-xmms --enable-largefiles --enable-fbdev --disable-tv --disable-dvbhead --disable-lirc --enable-xvmc CommandLine: '-v' '-stop-xscreensaver' '-vo' 'gl:lscale=1:cscale=1:yuv=3:osdcolor=0x0fefff' '/home/andrew/media/video/anime2/video/resident_evil/resident_evil_3_extinction_rus.mkv' '-audiofile' '/home/andrew/media/video/anime2/video/resident_evil/Resident Evil Extinction.ac3' init_freetype get_path('font/font.desc') -> '/home/andrew/.mplayer/font/font.desc' font: can't open file: /home/andrew/.mplayer/font/font.desc font: can't open file: /usr/local/share/mplayer/font/font.desc Using MMX (with tiny bit MMX2) Optimized OnScreenDisplay get_path('fonts') -> '/home/andrew/.mplayer/fonts' Using nanosleep() timing get_path('input.conf') -> '/home/andrew/.mplayer/input.conf' Parsing input config file /home/andrew/.mplayer/input.conf Input config file /home/andrew/.mplayer/input.conf parsed: 70 binds get_path('resident_evil_3_extinction_rus.mkv.conf') -> '/home/andrew/.mplayer/resident_evil_3_extinction_rus.mkv.conf' Playing /home/andrew/media/video/anime2/video/resident_evil/resident_evil_3_extinction_rus.mkv. get_path('sub/') -> '/home/andrew/.mplayer/sub/' [file] File size is 4561973814 bytes STREAM: [file] /home/andrew/media/video/anime2/video/resident_evil/resident_evil_3_extinction_rus.mkv STREAM: Description: File STREAM: Author: Albeu STREAM: Comment: based on the code from ???
