The tests which use encoders which either use slices or store the encoder thread count
keep a hardcoded value of 1

This will help test more threading code like in filters

When we don't adjust the Period start time, we don't need to
parse the earliest_presentation_time from the sidx boxes either.
Signed-off-by: Martin Storsjö <martin@martin.st>

This was only necessary to get playback to start with dash.js 1.2.0,
it has been fixed in the git version.

The previous behaviour was incorrect - the Period's start time
is irrespective of the actual first timestamp of the contents
within the period. The Period start time only says when, within the
global timeline, this particular piece should start to be played
back.
Signed-off-by: Martin Storsjö <martin@martin.st>

This should be more correct. This also should give more sensible
switching between video streams with different amount of b-frame
delay.

The current dash.js release (1.2.0) fails to start playback of
such files from the start (if the start pts is > 0), but this has
been fixed in the current git version of dash.js.

Also enable the use of edit lists, so that streams in many cases
start at pts=0.

Use the more generic approach with the delay_moov flag, instead of
having a update mechanism specific to this one single atom.
Signed-off-by: Martin Storsjö <martin@martin.st>

This delays writing the moov until the first fragment is written,
or can be flushed by the caller explicitly when wanted. If the first
sample in all streams is available at this point, we can write
a proper editlist at this point, allowing streams to start at
something else than dts=0. For AC3 and DNXHD, a packet is
needed in order to write the moov header properly.

This isn't added to the normal behaviour for empty_moov, since
the behaviour that ftyp+moov is written during avformat_write_header
would be changed. Callers that split the output stream into header+segments
(either by flushing manually, with the custom_frag flag set, or by
just differentiating between data written during avformat_write_header
and the rest) will need to be adjusted to take this option into use.

For handling streams that start at something else than dts=0, an
alternative would be to use different kinds of heuristics for
guessing the start dts (using AVCodecContext delay or has_b_frames
together with the frame rate), but this is not reliable and doesn't
necessarily work well with stream copy, and wouldn't work for getting
the right initialization data for AC3 or DNXHD either.

This allows writing edit lists even when track->entry == 0, if
the start times have been set.
Signed-off-by: Martin Storsjö <martin@martin.st>

If fragments == 0 it means we haven't written any moov atom yet.
If the empty_moov flag is set, we already have written an empty moov
atom at startup. Thus, the check for empty_moov is redundant.

This is in preparation for allowing writing the moov atom later,
even when using the empty moov flag.
