[FFmpeg-devel] [PATCH 05/36] avcodec/vp9_superframe_bsf: Allow up to eight frames in a superframe

[Andreas Rheinhardt]

Up until now, the bsf errored out with a message that there were too
many invisible frames if there were already seven frames cached even
when the new frame was not invisible. This has been changed.
