[x264-devel] Re: vlc + x264

[David Sackstein]

Hi everyone,
How does VLC transcode? I assume it performs a full decode and then an encode in the target format.
Does anyone know of an implementation that is more efficient for MPEG-2 to H.264? 
In particular, is there a real time transcode of MPEG-2 to H.264 in HD?

Alvin,

I am not sure at all, but try also to use --extra-ldflags=-fPIC in your 
configure call. It should do the trick. I have read somewhere (can't 
remember where) that you should compile AND link with this option to 
make the library "user" happy.
Hope this help

Joël
