[FFmpeg-devel] [PATCH 25/34] avcodec/libx264: Avoid copying packet data

[Andreas Rheinhardt]

Here the packet size is known before allocating the packet because
the encoder provides said information (and works with internal buffers
itself), so one can pass this information to ff_alloc_packet2() to
avoid the implicit use of another intermediate buffer for the packet data.
