[FFmpeg-devel] [RFC] [PATCH] proresenc_kostya: warn/reject on incorrect profile

Ticket #3846 is about an incorrect profile being used:
- The user wants alpha but the profile indicates to software there's no alpha
- Also, the encoder still encodes the alpha channel in spite of the profile

The attached patch is not the most user-friendly, but is preferred by
the encoder author, and has the merit to leave the final decision to
the user.

An alternative would be to select the profile based on the pixel
format. If a user wants to encode without alpha, he would then need to
change the pixel format as well as specify the proper profile, which
may not be obvious to him.
