As a personal note, but also as a hint I'm going to write here the script I use to convert video to avi:

for d in *; do
  ffmpeg -i "${d}" -c:v mpeg4 -b 2028k -acodec copy "${d}.avi" 

done

Instead the suggestion of @dinolib was this to make it compatible with PS3  :

ffmpeg -ss -00:00:01 -i "/nome/file/input" -c:v mpeg4  -qscale:v 5 -vtag XVID -c:a libmp3lame -b:a 128k -af aresample=async=1000 -map_metadata -1 "/nome/file/output"

Come appunto personale ma anche come suggerimento per tutti scrivo qui lo script che uso per convertire video in avi :

for d in *; do
  ffmpeg -i "${d}" -c:v mpeg4 -b 2028k -acodec copy "${d}.avi" 

done

Mentre il suggerimento di @dinolib era per rendere compatibile con PS3 :

ffmpeg -ss -00:00:01 -i "/nome/file/input" -c:v mpeg4  -qscale:v 5 -vtag XVID -c:a libmp3lame -b:a 128k -af aresample=async=1000 -map_metadata -1 "/nome/file/output"
