MP4Box can't import AVI files?

[hrgwea]

I've been using for some time FLVExtractCL.exe and MP4Box.exe to repair FLV files.
With FLVExtract I get the video and audio files and then I merge them with MP4Box.

However, every now and then there is some FLV file whose video content is extracted to an AVI file (normally FLVExtract produces a .264 video file).
Then when I try to merge the .avi file and the udio file with MP4Box it says it doesn't support that video file.

Is there some other command line utility that lets me merge an AVI file with its audio file?
Thanks.

Hi
Those flv files that you rebuild with MP4Box probably contain h264/aac.

Those "avi" flv files probably contain VP6/mp3.
They will probably rebuild using MKVmergeGUI instead of MP4Box.
(There's a command-line version too)

This is the output of MP4Box:

AVI VP6F video import - 0 x 0 @ 25.0000 FPS - 3002 Frames
Indicated Profile: Simple Profile @ Level 1
Import results: 0 VOPs (0 Is - 0 Ps)
import using Variable Frame Rate - Removed 3001 N-VOPs
Track ID 1 ctdelay failed

The format is AVI VP6F as you guessed.

mkvmerge.exe did the trick:

mkvmerge.exe -o file.mkv file.avi file.mp3

Thanks a bunch!

mkvmerge.exe did the trick

Also consider using FFmpeg to rebuild into avi instead of mkv.

ffmpeg -i file.avi -i file.mp3 -c copy output.avi
