Transcode et MPEG ?

Bonjour !

Je cherche à encoder un MPEG sorti d'une caméra numérique en divx ou avi histoire que ça soit plus pratique à manipuler (j'aime pas le mpeg et avidemux et consorts non plus) ...

Bref je m'installe transcode et toute une panoplie de lib pour mpeg, divx et xvid.

Je me motive à faire un 2pass et je tape :

pilou@sophie:/mnt/FTP/uploads$ transcode -i Cap0003.MPG -o /dev/null -x mpeg2,null -y divx5 -V -R 1

*** WARNING: The option -V is deprecated. ***

*** Transcode internal frame handling is now in YV12 / YUV420 ***

*** format by default because most codecs can only handle this format, ***

*** otherwise leading to unnecessary time and quality wasting conversions. ***

*** If you want to have to "old" behaviour (RGB24 as internal format), ***

*** then please use the new -1/--use_rgb option ***

Bon ça marche pas ; je teste 1pass au cas où :

pilou@sophie:/mnt/FTP/uploads$ transcode -i Cap0003.MPG -o /home/data/tmp/Cap0003.avi -x mpeg2 -y divx5 -V

Bref la même chose !

Quelqu'un saurait me dire d'où vient ce seg fault ?

Merci.
