[FFmpeg-devel] [PATCH v2 3/4] avcodec/mmaldec: re-use AVPacket for extra_data

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.
