[FFmpeg-devel] [PATCH 24/34] avcodec/zmbvenc: Avoid copying packet data

[Andreas Rheinhardt]

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