Hi there, I already reported this bug in the bugtracker one month again but Roberto Togni does not change the status and does not reply to my mail. So here is my report again for all of you ;) I am using MPlayer dev-SVN-r28234-4.3.2 (compiled it myself, but I have the same problems with the packaged mplayer) That's my system: Debian unstable (sidux, amd64 not IA64) 2.6.28 Kernel libc 2.7 ggc 4.3.3 ld 2.18 as 2.18 Intel Core 2 Duo T8100 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller When I try to demux an audio stream (6 channels) from DVDs that I ripped to my HD, some of the streams from the DVDs have the length of 1h 7m and 37 secs or of 1m and 25 secs. When I only extract 2 channels everything is ok. I have also the correct sound length when I open the DVD on the HD like this (with 2 channels): smplayer /path/to/dvd/on/my/HD I tested 2 DVDs with different options, here are my results: Basically I used the following options: mplayer -nolirc -nocache -noframedrop -noconfig all -mc 0 -vc dummy -vo null -ao pcm:waveheader:file=/tmp/fifo.129 -srate 44100 -af volnorm=1,lavcresample=44100 -channels 2 -aid 129 -dvd-device "/path/to/my/DVD/on/my/HD/" dvd://1 I opened the output of mplayer while it was still demuxing (while) and after mplayer was finished (after) and used sound streams 128 and 129: DVD 1: * 6 channels without srate option (48Khz to 44kHz): 128: while: 1,7,37 after: 1,25 129: not tested * 2 channles with srate option (48kHz to 44kHz): 128: while: 3:22:53 (console output of mplayer shows 2.16.41) NOTE: smplayer /path/to/dvd shows also 2:16:41, so this should be the correct time after: 2:16.41 same thing with 129 DVD 2: 6 channels with srate option: 128: while: 1,7,37 after: 1,25 129: while: 1.7.37 after: 1,25 I you want me to do anything, if you need output of mplayer or something then just let me know. BTW: A friend of mine has a similar problem with a DVD at the sound position 3 h and 6 min with 2 audio channels on a 64 bit system. Another friend demuxed the same DVD on his 32 bit system and his sound is ok. So this might be a 64 bit system issue. Thanks for your good work! HennR
