This adds an option to set the service type in mpegts as defined in ETSI 300 468.
I added what I believe are the most useful service types as pre defined values,
the others can be sent by using their hexdecimal form directly (e.g. -mpegts_service_type digital_radio, -mpegts_service_type 0x07).
I've been using this patch in order to pipe internet radio stream (originally as HLS/m3u8) from ffmpeg to tvheadend,
when the service type set right tvheadend recognize the mpegts stream as a radio channel.
The patch in its original form was written by linuxstb from freenode's hts channel which allowed me pushing it upstream.
This close issue 4118.

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).

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.

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.

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].

This uses page duration instead of byte size to determine when to buffer
the page. Also, it tries to avoid continued pages by buffering the current
page if there are already packets in the page and adding the next packet
would require it to be continued on a new page. This can improve seeking
performance.
The default page duration is 1 second, which is much saner than filling
all page segments by default.
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.
