[FFmpeg-devel] [PATCH 26/34] avcodec/libxavs: Avoid copying packet data

[Andreas Rheinhardt]

When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data.

ff_alloc_packet2() call (for the actual packets, not this end-of-stream
packet), yet the size known in advance is not exact.
