[AMD Official Use Only - General] We would like to add that in Mesa first to let vaapi path accept 10bit input and HW to convert it to 8bit if it makes sense to do so. Then get a chance to apply it to ffmpeg.

If it works (the encoder accepts the 10 bit input even if it encodes it as 8bit), then i don't see why not. I assume it would also be faster than using swscale to convert said 10bit input to nv12 before passing that to the encoder. Removing support for a pixel format as input in an encoder needs a reason other than "It's rarely used", more so when it's a single line. It either needs to not work, or somehow get in the way of further improvements. > > Thanks, > Ruijing > > -----Original Message----- > From: ffmpeg-devel <ffmpeg-devel-boun...@ffmpeg.org> On Behalf Of > James Almer > Sent: Friday, November 25, 2022 6:25 PM > To: ffmpeg-devel@ffmpeg.org > Subject: Re: [FFmpeg-devel] [PATCH] lavc/qsvenc_h264: don't support > P010 format > > On 11/25/2022 8:20 PM, Soft Works wrote: >> >> >>> -----Original Message----- >>> From: ffmpeg-devel <ffmpeg-devel-boun...@ffmpeg.org> On Behalf Of >>> James Almer >>> Sent: Friday, November 25, 2022 8:48 PM >>> To: ffmpeg-devel@ffmpeg.org >>> Subject: Re: [FFmpeg-devel] [PATCH] lavc/qsvenc_h264: don't support >>> P010 format >>> >>> On 11/25/2022 3:03 PM, Soft Works wrote: >>>> >>>> >>>>> -----Original Message----- >>>>> From: ffmpeg-devel <ffmpeg-devel-boun...@ffmpeg.org> On Behalf Of >>>>> Anton Khirnov >>>>> Sent: Friday, November 25, 2022 2:46 PM >>>>> To: FFmpeg development discussions and patches <ffmpeg- >>>>> de...@ffmpeg.org> >>>>> Cc: Haihao Xiang <haihao.xi...@intel.com> >>>>> Subject: Re: [FFmpeg-devel] [PATCH] lavc/qsvenc_h264: don't >>> support >>>>> P010 format >>>>> >>>>> Why? >>>> >>>> It's rarely used.
