| hi,
I want to convert a dv-pal file (made with final cut) in an avi divx by using preset divxffmpeg. The result is a file without audio track. This is the log in the end of the process: Input #0, yuv4mpegpipe, from 'pipe:': Duration: N/A, bitrate: N/A Stream #0.0, 25.00 fps(r): Video: rawvideo, yuv420p, 640x352 Output #0, avi, to '/Volumes/LaCie/Capture Scratch/emecnet meet eu - dic.07/segmento prova.mov.ff.avi.e.avi': Stream #0.0, 25.00 fps(c): Video: mpeg4, yuv420p, 640x352, q=2-9, 1265 kb/s Stream mapping: Stream #0.0 -> #0.0 bench: utime=1.120s video:565kB audio:0kB global headers:0kB muxing overhead 1.146726% FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard Mac OSX universal build for ffmpegX libavutil version: 49.0.0 libavcodec version: 51.9.0 libavformat version: 50.4.0 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/Volumes/LaCie/Capture Scratch/emecnet meet eu - dic.07/segmento prova.mov': Duration: 00:00:03.2, start: 0.000000, bitrate: 30220 kb/s Stream #0.0(eng): Audio: pcm_s16be, 44100 Hz, stereo, 1411 kb/s Stream #0.1(eng), 25.00 fps(r): Video: dvvideo, yuv420p, 720x576 Codec type mismatch for mapping #0.1 -> #0.0 If I play the source file with quicktime I have audio. Can someone help me? | ||||

The audio stream is listed before the video stream. ffmpegX wants that reversed. I checked if that can be adjusted by using the "Invert mapping" checkbox, but it seems to have no effect for my test DV source. :( All DV here are video before audio. I have no idea why Final Cut would export a DV file with reversed streams. | ||||

| You can reverse the stream order manually with QuickTime Pro.
Open the dv.mov in QuickTime Player. Export Sound to AIFF. Show Movie Properties on the dv.mov. Delete the Sound Track. Open the AIFF file, select all, copy to clipboard. Switch to dv.mov file. Select all. Add to Movie. Show Movie Properties, check: video is listed before audio. Save as self-contained movie. ffmpegX should now convert both video and audio. |
