d5d2632e3a avformat/hlsenc: Fixed initial setting for end_pts
This patch fixes Bug #6868
Sometimes end_pts is getting initialized to audio stream's
first pts, while the duration is calculated based on video stream's pts.
In this patch the end_pts is initialized with the correct stream's first pts.

143552095d avformat/hls: Obey AVProgram discard flags
Currently HLS demuxer only obeys AVStream discard flags but not
AVProgram (which bandwidth variants appear as) discard flags.

Fix that.

5b4baf1506 libavformat/rtpenc_mpegts: check avformat_new_stream() return value
The function avformat_new_stream() returns a NULL pointer on failure.
However, in function rtp_mpegts_write_header(), its return value is not
validated before it is dereferenced. Check the return value against NULL
to avoid potential NULL dereference.

26c0c84784 avformat/avienc: fix fields-per-frame value for interlaced video streams
Writes one set of field framing information for progressive streams and
two sets for interlaced streams. Fixes ticket #6383.

Unfortunately the OpenDML v1.02 document is not very specific on what
value to use for start_line when frame data is not coming from a
capturing device, so this is just using 0/1 depending on the field order
as a best-effort guess.
