[vlc-devel] vlc-devel Digest, Vol 46, Issue 77

[cherqui nawfal]

Okey i just got the command  vlc -p x264 --advanced  to play with x264 but i
am not sur that it can really help to reach the level of ffmpeg.

I did not build ffmpeg , i just followed this howto to install it with vlc
http://wiki.videolan.org/User:J-b . But still i can not understand why it
can not use h264 codec .
