9ea6d2149e avcodec/decode: add a flags parameter to ff_reget_buffer() 
Some decoders may not need a writable buffer in some specific cases, but only
a reference to the existing buffer with updated frame properties instead, for
the purpose of returning duplicate frames. For this, the
FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential
allocations and buffer copies when they are not needed.

2eebcda10a avcodec/screenpresso: return the packet size instead of 0 
Most decoders return the amount of data used.
This is more consistent

ec8a69fab6 screenpresso: Correctly handle keyframes 
The first byte contains compression level together with keyframe status.
When a frame is not interpreted correctly, its data is summed to the
reference, and would degrade over time, producing an incorrect result.
