Trouble with MP4 and MOV formats.

[fesmitty77]

I just installed ffmpeg and I am finding that the formats that I need most, MP4 and MOV, are not working properly. the encoding process is almost instant, and the files that it produces, while named correctly, are corrupt. The AVI format workd only part of te time, and I am generally stuck with the FLV files that I startd with. Any Suggestions? I will post the log below:


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
Encoding started on Mon Dec 7 21:26:53 EST 2009
Seems that stream 1 comes from film source: 1000.00 (1000/1) -> 24.00 (24/1)
Input #0, flv, from '/Users/andrewsmith/Desktop/213708.flv':
Duration: N/A, bitrate: N/A
Stream #0.0: Audio: mp3, 22050 Hz, stereo
Stream #0.1, 24.00 fps(r): Video: flv, yuv420p, 320x234
Codec type mismatch for mapping #0.0 -> #0.0

[Case]

Codec type mismatch for mapping #0.0 -> #0.0

This is a error that will pop up on ffmpeg conversions with stream #0.0 as audio and stream #0.1 as video. The solution is to alter the stream mapping. You may do so in ffmpegX by setting the "invert mapping" checkbox in the Audio tab. This will set mapping #0.0 -> #0.1 and #0.1 -> #0.0, so that audio converts to audio and video converts to video.

Cool. I did that, unfortunately there is now no file being created at all....

Please post the new log.

ffmpeg can read many video codecs, but not all. The video codec of this FLV isn't natively supported. But there is a way to help ffmpegX support it:
1/ Install Perian to add FLV support to QuickTime, including this 0x0004 video codec.
2/ Tell ffmpegX to use QuickTime (and Perian) for reading the source file: Set "Decode with QT" in the Options tab. Encode.
