3efe0393e4 hevc: make avcodec_decode_video2() fail if get_format() fails 
Personally, I need the decoder to back out if get_format() returns no
usable pixel format. This didn't work because the error code was not
propagated down the call chain. This in turn happened because the
variable declaration removed in this patch shadowed the variable, whose
value is returned at the end of the function. Consequently, failures of
decode_nal_unit() were ignored in this place.

eafbc6716c vmnc: Delay pixel size check 
Some clients incorrectly set 24 as bits_per_coded_sample, while
the actual value is preserved in one of the codec headers.
In order to work around this, delay the check until decode_frame().

b012bd5068 libavcodec/x265: detect csps in libx265_encode_init_csp() 
Without this change, if you link with an 8bit libx265 and try to specify
a 10bit input color space via:

  ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4

It will error with:

  Incompatible pixel format 'yuv420p10le' for codec 'libx265',
  auto-selecting format 'yuv420p'

With this fix, it will learn if a 10bit libx265 is available at startup,
and thus allow 10bit input color spaces.
