[FFmpeg-devel] [PATCH 3/3] avcodec/utils: Favor using the internal->byte_buffer in ff_alloc_packet2()

[Michael Niedermayer]

From: Michael Niedermayer <michael at niedermayer.cc>

This would allow dropping min_size

This causes matrixbench encoding to rawvideo to drop in speed from
4.204 to 4.210sec
The effect has been previously seen to be much larger at higher
resolutions
