[FFmpeg-devel] [PATCH] avformat/hlsenc: Add resend_headers option

[huheng]

Add pat and pmt table at start of each segment in single_file mode enhanced
compatibility of hls stream. Because some hls clients separate parsing segment
of hls stream, the absence of pat/pmt will cause parsing to fail.

Is it need check hls->segment_type == SEGMENT_TYPE_MPEGTS here?
