It's not used anywhere internally.

Salvage its documentation for ffio_read_pause.

URLContext.filename should be used directly.

URLContext.max_packet_size should be used directly.

The previous commit didn't do this straight away, to keep the
diff slightly simpler.

This avoids issues where EOF at the end of the segment is given
the variant demuxer. Now the demuxers only see one single data
stream (as when using the applehttp protocol handler).

This is a preparation for a restructuring of the demuxer, to
minimize the later diff.

The unbuffered API will be made private and it's not used anywhere
internally.

They're unimplemented and nobody cared to do anything with that for
10 years.

fixes Issue 2674

The unbuffered URLContext API will be made private, so there's no point
in this function being public.

It doesn't look fit to be a part of the public API.

Adding a temporary hack to ffserver to be able to use it, should be
cleaned up when somebody is up for it.

Use it instead of url_is_streamed and AVIOContext.is_streamed.

In particular, now it assumes that
a) chapters are chronologically ordered
b) chapters have the same timebases
c) duration of the stream is known
and asserts if any of these is not met.

Make it properly deal with harsher conditions.

'keyframes' metatag is not part of the standard, it is just
convention to use such kind of metatag information for indexing.
Structure is following, it allows to have it inconsistent:
keyframes:
 times (array):
  time0 (num)
  time1 (num)
  time2 (num)
 filepositions (array)
  position0 (num)
  position1 (num)

A zero sized stsc run doesn't make a lot of sense but the spec does not
prohibit them and MPlayer VLC demuxers support them.

According to the RFC, GET_PARAMETER should be used for
this, and according to a report from Tim Ouellette,
OPTIONS doesn't work for keeping the connection alive for some
servers. Also, live555 uses GET_PARAMETER for this purpose.

When a normal Block is parsed, duration is initialized to
AV_NOPTS_VALUE.  If it is not changed, then the track's default
duration is used.  But for SimpleBlock, duration is initialized to
0 instead of AV_NOPTS_VALUE.  This is due to the difference in how
EBML_NEST vs EBML_PASS are processed.  Setting duration to 0 leads
eventually to wrongly estimate the frame duration in util.c
