[FFmpeg-devel] [PATCH v3 2/5] avcodec/mmaldec: re-use AVPacket for extra_data

[Andreas Rheinhardt]

From: Ho Ming Shun <cyph1984 at gmail.com>

extra_data and normal packets (from ff_decode_get_packet) processing do
not overlap, thus we can re-use the spare AVPacket to send to
ffmmal_add_packet.

Furthermore, this removes allocation of AVPacket on the stack and stops
using deprecated av_init_packet.
