[FFmpeg-devel] [RFC][GSoC][PATCH v2 6/6] ffplay: add av_packet_buffer_filter to filter packet buffer

From: spartazhc <spartazhc at gmail.com>

hls_read_header will add all streams to s->internal->packet_buffer.
Use av_packet_buffer_filter to remove the AVPackets from other streams that
are not needed, otherwise abr will allow them to be added to ffplay's
packet_queue.
