[vlc-devel] VDPAU output with OSS driver

So, if I try to disable these checks, just for testing purposes (I
understand query hw for support it's a better thing to do than
shooting in the dark, but ...) since in my case the exposed
information are not reliable, the magic could happen :-) ?

I've tried commenting the vdp_decoder_query_capabilities() check in
vdpau/avcodec.c (see: http://pastebin.com/JQ1BKf8Q) which was
originating the error.

The results are encouraging, since the unsupported profile and YCbCr
errors are gone ... but then fails to display any pictures:

I know what I've done is dirty, but again is just a test to see if
that was the only problem... but there must something else somewhere
else.

Any hints you can give me about if and where to change code, to get
video playing ? (before start bothering MESA guys :-))

Thanks again !
