FFmpeg vdpau decoding

[topilski]

Hi, i have Orange Pi One device, last build from ffmpeg (build from snapshot sources), and i'am trying to convert big buck bunnny video. i use next command line:
DISPLAY=:0 /usr/bin/ffmpeg -hwaccel vdpau -i b.mov out.mp4 -v debug

but receive the error: Error retrieving the data from VDPAU surface, may be you can help me why it can happen?

Hi, is this issue solved already? I'm not sure how libvdpau-sunxi is used by ffmpeg conversion. Is the error maybe because of missing get_bits_ycbcr functionality?

[topilski]

Hi @rellla, i forked from your sources and remark 1 line ( fastogt@e0059f8 ), after that vdpau decoding worked. Yes this issue is missing get_bits_ycbcr functionality.

@nulijiabei
it does not support retrieving decoded pixels back
mplayer's vdpau implementation does need this and works ok
