Default Re: 10-bit color and VDPAU

There are countless devs on Doom9/Doom10/Avs/etc who would be surprised to hear that VDPAU decoding for Hi10P is a software-solvable issue.

I was under the impression that only NVS/Quadro cards could do it, if at all.

295.09 don't support Hi10p (10bit depth) x/h264 profile

i think is VDPAU output decoder problem.

works well with xv output + ffh264 codec

sample

(sorry. i no have link nvidia ftp to upload)

vdpau+ffh264 will decode since it isn't gpu accelerated

vdpau+ffh264vdpau won't

Can anyone attach a clip that reproduces the issue or upload it to the partner SFTP as per the sticky instructions?
Current mplayer2 (maybe mplayer too) crashes after complaining:
Code:
VDec: vo config request - 1280 x 720 (preferred colorspace: Planar 420P 10-bit little-endian)
Trying filter chain: vo
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
SwScale params: -1 x -1 (-1=no scaling)
Trying filter chain: scale vo
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

MPlayer interrupted by signal 11 in module: check_framedrop
Any Hi10p sample should do, I found some here: http://ps-auxw.de/10bit-h264-sample/.
For convenience, I have also reuploaded one of those to your ftp "10bit-eldorado.mkv", I hope that was ok.

Maybe Nvidia knows something that we don't, but if VAAPI, CrystalHD, and XvBA can't do Hi10P on the GPU, I don't see VDPAU being special despite being a much larger API.

I think you took my post the wrong way; I said I didn't think our decode hardware supported 10bpc either...
