Hi there, We experience exactly the same behaviour with a .mov file that contains a dvvideo stream. This is our output: ./ffmpeg -i input.mov -f mpeg -vcodec mpeg1video -b 1500 -acodec mp2 -ab 224 -deinterlace output.mpg ffmpeg version 0.4.9-pre1, build 4754, Copyright (c) 2000-2004 Fabrice Bellard configuration: --disable-ffserver --disable-ffplay built on May 4 2005 21:21:31, gcc: 3.3.5 (Debian 1:3.3.5-8) Input #0, mov,mp4,m4a,3gp,3g2, from 'input.mov': Duration: 00:02:48.0, start: 0.000000, bitrate: 2731 kb/s Stream #0.0: Video: dvvideo, yuv420p, 720x576, 25.00 fps Stream #0.1: Audio: pcm_s16be, 48000 Hz, stereo, 1536 kb/s Output #0, mpeg, to 'output.mpg': Stream #0.0: Video: mpeg1video, yuv420p, 720x576, 25.00 fps, q=2-31, 1500 kb/s Stream #0.1: Audio: mp2, 48000 Hz, stereo, 224 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 2 q=0.0 Lsize= 498kB time=0.0 bitrate=101990.4kbits/s video:76kB audio:413kB global headers:0kB muxing overhead 1.646226% The duration it reports is incorrect - this should be 15.11 seconds. And the encoding "stops" at frame 2, although there are 378 frames (according to TMPGEnc). Other info according to TMPGEnc 3.0 XPress: Video mode : Interlaced Field order : Bottom field first Aspect ratio : Pixel 12:11 (PAL 4:3) Frame rate : 25 fps Image resolution: 720x576 Reader module : QuickTime file reader *NB*: ffmpeg 0.4.7 handles the file correctly! (Though the video and audio quality are not very good, but still.) This is the output from ffmpeg 0.4.7: ./ffmpeg -i input.mov -f mpeg -vcodec mpeg1video -b 1500 -acodec mp2 -ab 224 -deinterlace output.mpg Input #0, mov, from 'input.mov': Duration: 00:00:15.1, bitrate: 30347 kb/s Stream #0.0: Video: dvvideo, 720x576, 25.00 fps Stream #0.1: Audio: pcm_s16be, 48000 Hz, stereo, 1536 kb/s Output #0, mpeg, to 'output.mpg': Stream #0.0: Video: mpeg1video, 720x576, 25.00 fps, q=2-31, 1500 kb/s Stream #0.1: Audio: mp2, 48000 Hz, stereo, 224 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 465 q=4.0 size= 3690kB time=3.8 bitrate=8022.4kbits/s Sjakie.
