How can I fix AVI files with a broken index or bad interleaving?

To avoid having to use -idx to be able to seek in AVI files with a broken index or -ni to play AVI files with bad interleaving, use the command

mencoder -forceidx -nobps  -ovc copy -oac copy -o outidx.avi input.avi

to copy the video and audio streams into a new AVI file while regenerating the index and correctly interleaving the data.

Of course this cannot fix possible bugs in the video and/or audio streams

transcode -i input.avi -P 1 --avi_limit 128 -b 128  -o out.avi

Réaligner chunks vidéo et audio pour qu'il n'y ait pas de désynchronisation après le split

transcode -i input.avi -P1 -N 0x55 -y raw -o out.avi

Split

avisplit -i out.avi -o base -s 512

TOUT EN UNE SEULE OPERATION avec transcode

transcode -i input.avi -P1 -N 0x55 -y raw -o out --avi_limit 512

ffmpeg -threads N

ffmpeg -i input.mp4 -y -threads 2 -map 0.0:0.0 -f avi -vcodec copy -b 940 -aspect 4:3 -s 640x480 -r pal -g 240 -me epzs -qmin 2 -qmax 15 -acodec mp3 -ab 128 -ar 48000 -ac 2 -map 0.1:0.1 -benchmark out.avi
