[vlc-devel] [PATCH 2/2] avcodec: prioritise vaapi over vdpau

[Thomas Guillem]

Favor VAAPI over VDPAU: VDPAU is deprecated and present on less systems than
VAAPI. Furthermore, the try and fail of VDPAU vout/va take much longer than the
VAAPI one (around twice the time, that is 100-200ms). VAAPI will only be used
for direct rendering by default, so VDPAU will still be used instead of VAAPI
with CPU copy
