I wasn't familiar with this feature, but one of the commits has a description that seems pretty useful.

Intra-refresh is a feature for smoothing out fluctuation in bitrate by replacing a whole intra frame by several intra strips distributed in several continous frames, it is also used in suppressing error propagation situation.

The merge states:

intra-refresh requires application
side to have a logic of sending the corresponding refresh
commands for completing the refresh cycle

Does this mean that ffmpeg needs changes too, to actually use this?
