The DTS needs to be resynched against the segment start PTS, or the
resulting DTS may result < PTS.

Subject: [FFmpeg-user] pts/dts error using reset_timestamps while splitting a DVD
Date: Sat, 19 Jan 2013 08:58:27 +0000
Replace wrong "EXT-X-ALLOWCACHE" with "EXT-X-ALLOW-CACHE", and value 1/0
with YES/NO, as per spec.
Fix trac ticket #2228.

The new options reset the timestamps at each new segment, so that the
generated segments will have timestamps starting close to 0.
It is meant to address trac ticket #1425.
From the M3U8 specification:
|The EXT-X-MEDIA-SEQUENCE tag indicates the sequence number of the first
|URI that appears in a Playlist file.
Previously it was using the list index number. Also remove now unused
list_count field.
The segment muxer presumes the use of AVFMT_GLOBALHEADER, ssegment should
be use in case of formats which requires no global headers.
Regression introduced when merging
0826d8513d.
Some muxers do not allow stream if codec_tag is incompatible.
Sometimes the passed input codec's codec_tag is not compatible with the
output muxer.
Because the codec_tag field of the segment muxer cannot be set, ffmpeg.c
doesn't know how to handle these cases.

avconv provides an option to set it externally and there isn't a way for
the outer demuxer to report the inner demuxer flag.
Solves a bad interaction between mpegts and x264, but requires
additional setting for the user.

This makes sure any buffered data is written to the segment, for
muxers that buffer up data internally (e.g. fragmented mp4).
Signed-off-by: Martin Storsjö <martin@martin.st>
This makes sure new inline headers are emitted when the next
packet is written. This allows segmenting mpegts without calling
write_header/write_trailer (nor freeing/reiniting the muxer)
for each segment.
Signed-off-by: Martin Storsjö <martin@martin.st>
Some segmented formats (such as fragmented mp4) are "bare", as in,
the segment files do not have the same headers/trailers as full normal
files of that format have.

This makes sure the muxers are set up in the way they expect
with no data left around from the previous run (which could
cause various issues including memory leaks, depending on the chaine
muxer).
This fixes memory leaks with the mpegts and flv muxers. It also
makes the usage of chained muxers correct.
Signed-off-by: Martin Storsjö <martin@martin.st>
With this change, the segmenter muxer doesn't rely on anything
not available/supported to libavformat external users, making
the segmenter muxer do things just like a normal segmenter
application using libavformat would do.
Signed-off-by: Martin Storsjö <martin@martin.st>
Before, the chained muxer reused the AVStreams array from
the outer muxer, which made it impossible to use the proper
public functions (such as av_write_frame) when calling the
chained muxer.
