[FFmpeg-devel] [PATCH 1/1] avformat hls check discard state of streams always

[vectronic]

The discard needs to be checked on a stream even after the first packet is read. The first packet has already been read as part of calling avformat_find_stream_info. This means that setting AVStream->discard on a stream after having determined the stream info for the HLS package had no effect and unwanted packets were returned by subsequent calls to hls_read_packet.
