Subject: Re: [FFmpeg-devel] [PATCH] lavc/qsvenc_h264: don't support
P010 format
Why?
It's rarely used. There's not even a hwaccel that can decode this.
The dxva2/d3d11 hwaccels seemingly do, as does the qsv decoder. And
being rarely used alone is not a reason to remove something. There needs
to be some benefit to justify it (Simplifying maintenance, removing
legacy code, etc).
Also, p010 can be generated by swscale, and the only other software
pixel format supported in this list is nv12, which is 8bit. If we remove
p010, we would be making 10bit encodings not longer work with the output
of software decoders as input, right?
