[FFmpeg-devel] [PATCH] avformat/framecrcenc: allow setting which side data parameters are printed

[James Almer <jamrial@gmail.com>]

For some side data types, the size is dependent on the arch at runtime, which
is not good for FATE tests.
Add an option to set which parameters may be printed, starting with size.
