[vlc-devel] VDPAU output with OSS driver

[Android Jack]

Hi, and thanks for the reply !

Before forcing VDPAU as video output, I've already tried leave it to
default "Automatic" and the option "Accelerated video output (Overlay)" is
checked (the old option --ffmpeg-hw is not present anymore), but the result
is that, after trying VDPAU it falls-back to xv, starting to skip pictures
and the CPU load goes 100%:

Is this the expected performance/behaviour or there is any other
option/switch I could touch, to make things go smoother ?

It's soo annoying that mplayer can handle all this fine :-) ... but I want
to use VLC for an RTP application (and mplayer is much worse in that ...)

Regards.
