It doesn't work. I've also updated the mplayer/mencoder package since, but the problem persists. I am using mencoder to covert my video to x264/mp3 format, but just noticed that the converted avi file's audio stream is about 10% shorter than the video stream: Video stream: 712.690 kbit/s (89086 B/s) size: 1532284 bytes 17.200 secs 261 frames Audio stream: 46.772 kbit/s (5846 B/s) size: 85032 bytes 14.544 secs The command that I used is: mencoder -of avi -oac mp3lame -lameopts abr:br=48:vol=2.2 -ovc x264 -vf harddup -srate 8000 -o imgp2163-.avi imgp2163.avi Here is its full log: MPlayer SVN-r29980 (C) 2000-2009 MPlayer Team success: format: 0 data: 0x0 - 0x31d7c0 VIDEO: [MJPG] 320x240 24bpp 15.000 fps 1367.8 kbps (167.0 kbyte/s) [V] filefmt:3 fourcc:0x47504A4D size:320x240 fps:15.000 ftime:=0.0667 Opening audio decoder: [pcm] Uncompressed PCM audio decoder AUDIO: 8000 Hz, 1 ch, s16le, 128.0 kbit/100.00% (ratio: 16000->16000) Selected audio codec: [pcm] afm: pcm (Uncompressed PCM) Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Unsupported PixelFormat -1 Selected video codec: [ffmjpeg] vfm: ffmpeg (FFmpeg MJPEG) . . .

But the problem persists with and/or without the '-noskip' option. Moreover, when converted without the '-noskip' option, the A/V will be off sync. I've upload the imgp2163.avi file to ftp mplayerhq.hu /MPlayer/incoming/, giving it a name as "mencoder_coverts_audio_stream_shorter.avi". Please investigate.
