[Freeswitch-users] H264 transcoding

[William King]

libvlc is LGPL http://www.videolan.org/press/lgpl.html and there is now 
a mod_vlc(though it doesn't yet support video streams). The user can 
choose to build vlc with only the LGPL components or add the more 
'adverse' modules. In none of the LGPL packages of libvlc is ffmpeg 
enabled, but there is a module for libvlc for ffmpeg. 
http://wiki.videolan.org/FFmpeg

The only pieces now may just be the FS side of things for video.
