Hi,
I am using XLib to display my grabbed frames but it can display 6 ou 7 fps !! Do you know how to improve my display ?
Sure. You have to use: 1) X Shared Memory extension, or2) XVideo extension - better way. It will provide hardware support for color spaces transformation and scaling.
For details, just see the latest mpeg2dec sources, /libvo/video_out.x11.c it's the SIMPLEST which available on market :-)
