cf589faa5b movenc: Add a flag for using default-base-is-moof in tfhd atoms
Similarly to the omit_tfhd_offset flag added in e7bf085b, this
avoids writing absolute byte positions to the file, making them
more easily streamable.

This is a new feature from 14496-12:2012, so application support
isn't necessarily too widespread yet (support for it in libav was
added in 20f95f21f in July 2014).

55f03d8726 hlsenc: Add parameter -hls_allow_cache
The -hls_allow_cache parameter enables explicitly setting the
EXT-X-ALLOW-CACHE tag in the manifest file. That tag indicates
whether the client MAY or MUST NOT cache downloaded media
segments for later replay.

Valid values are 1 (=YES) or 0 (=NO) and the EXT-X-ALLOW-CACHE
will not show in the manifest for other values (or if
-hls_allow_cache is not used.

f685f7d7a8 hlsenc: single_file, support HLS ver 4 byteranges
This adds a new option -hls_flags single_file that creates one .ts file
for HLS and adds byteranges to the .m3u8 file, instead of creating one
.ts file for each segment.

This is helpful at least for storing large number of videos, as the
number of files per video is drastically reduced and copying and storing
those files takes less requests and inodes.

This is based on work by Nicolas Martyanoff, discussed on ffmpeg-devel
in July 2014. That patch seems abandoned by the author, and contained
unrelated changes. This patch tries to add the minimum amount of code to
support the byterange playlists.

fa6716c66d libavformat/segment: change segment_list_size behavior to match hls_list_size behavior.
Make the segment muxer keep segment_list_size segments instead of
segment_list_size + 1 segments. This patch also changes the
documentation for segment_list_size to reduce possible confusion over
how many segments are kept.

this allows the segment list to
be limited to containing only one segment which used to be impossible
because a segment_list_size of 0 kept all the segments and a
segment_list_size of 1 kept 2 segments.

3e73d14290 lavf: Add WebM DASH Manifest Muxer
This patch adds the ability to generate WebM DASH manifest XML using
ffmpeg. A sample command line would be as follows:

ffmpeg \
  -f webm_dash_manifest -i video1.webm \
  -f webm_dash_manifest -i video2.webm \
  -f webm_dash_manifest -i audio1.webm \
  -f webm_dash_manifest -i audio2.webm \
  -map 0 -map 1 -map 2 -map 3 \
  -c copy \
  -f webm_dash_manifest \
  -adaptation_sets “id=0,streams=0,1 id=1,streams=2,3” \
  manifest.xml

It works by exporting necessary fields as metadata tags in matroskadec
and use those values to write the appropriate XML fields as per the WebM
DASH Specification [1]. Some ideas are adopted from webm-tools project
[2].
