Comment:

 I tested the 0.6, 0.7 and 0.8 release branches and both VA-API and VDPAU
 were always auto-detected.
 The reason is that they are system libraries like zlib and bzlib (which
 are also auto-detected). If you have strong reasons why this behaviour
 should be changed, I suggest you send a patch to ffmpeg-devel. (I believe
 I was originally against auto-detecting VDPAU, but I am also against
 changing behaviour.)

 I tried to fix configure --help output (for VA-API and VDPAU, it now looks
 identical to zlib and bzlib documentation). If you find it completely
 uncomprehensive, please say so.
