If your hardware decoding does not produce valid alpha data (0xFF
for opaque, 0x00 for completely transparent), you cannot use an
FFmpeg pix_fmt that defines alpha for decoding.
If you define a pix_fmt that does not contain alpha information (as
needed for your hardware decoder), please do not use "A" in its
name.
