Previously if there are no bytes remaining, SkipBytes(0) would fail,
which results in parsing error in
AACAudioSpecificConfig::ParseProgramConfigElement.
Fixes#875.

I.e. the flag --generate_sidx_in_media_segments,
--nogenerate_sidx_in_media_segments work for both single-segment
and multi-segment mode with this change.
Related to #862.

The reference count in 'sidx' box is a uint16 field, which allows at
most 0xFFFF entries, i.e. at most 0xFFFF subsegments, which is roughly
18 hours for one second segments.
Do not fail packaging when it happens. Instead, generate a warning and
truncate the number of references to 0xFFFF instead.
Note that the actual number of mp4 fragments in the mp4 file can still
be more than 0xFFFF. The stream will not play to the end in DASH, but
it will play successfully in HLS.
Workarounds #862.

This allows us to have presentationTimeOffset for text streams since
this needs to appear on a SegmentList/SegmentBase/SegmentTemplate.

This also changes the callbacks a bit to (a) avoid passing references
for already ref-counted types, and (b) don't pass PID since the
parent knows this and gives it to the child parser.

This changes the default MP4 output to use TTML and adds a way to
choose which one is used. This is done with 'format=ttml+mp4' or
'format=vtt+mp4'.
This also fixes the boxes output in WebVTT in MP4.
Change-Id: Ieaa7fc44fbf4dc020a5bb70cfa3578ec10e088ce
This only supports TTML output; meaning the user can convert WebVTT
into TTML, but not the other way around. This will be useful for
DVB-sub subtitles that would be better supported within TTML.
This only adds text-based output; a follow-up will add MP4 support.

- Use std::move to transfer ownership.
- Avoid libxml primitives outside XmlNode.
- Have attribute setting return errors.
- Mark bool returns with WARN_UNUSED_RESULTS and use return value.
- Use std::string over char*.

Alpine does not support python3 yet, but depot_tools enabled python3
by default recently.
Disable python3 for now.

This adds a new path when parsing MPEG2-TS streams to ignore unsupported
streams. This allows extracting supported streams when some of the
streams are unsupported. For example, you can extract audio from a
file that has unsupported video.

This adds more generic settings for regions and CSS styles. These are
global settings, so they go on the StreamInfo object.

Always set AUTOSELECT=YES for DVS tracks and also exclude it from
standard AUTOSELECT and DEFAULT configuration logic.

Now text cues are composed of nested fragments that can be individually
styled. This allows portions of the cue to be bold, etc. The
WebVTT parser doesn't parse the inputs, but the original tags are
preserved in WebVTT output. The WebVTT output will add tags if the
style elements are present in the cue object.

We currently have a bug about non-deterministic output in the MPD
generator. This works around that bug by optionally doing everything
in a single thread. This allows us to run manifest comparisons without
making the major changes needed to add that feature.

Now the Cue settings are a generic object that is parsed in WebVTT.
This will allow setting the settings in different parsers without having
to use WebVTT-specifics.
Change-Id: I36689bec725bd2e515af962b7174fc5977f96fa2
This sets the groundwork for more generic text cues by having a more
generic object for the settings and the body. This also changes the
TextSample to be immutable and accepts the fields in the constructor
instead of using setters.

Now text-based WebVTT also uses the generic media pipeline. This
converts the WebVttTextOutputHandler to a WebVttMuxer to be more
consistent with the other muxer types.
This also allows choosing between single-segment text and multi-segment.
Before, we would generate both and use single-segment for DASH and
multi-segment for HLS; but now you can choose between either and either
are supported in both DASH and HLS.

Now the same pipeline for handling the audio/videos streams will handle
the segmented text streams too. This doesn't apply to the text output,
only to the MP4 variants. This also fixes a bug where we added the
X-TIMESTAMP-MAP tag even when there wasn't TS streams; this doesn't
otherwise change the behavior around that tag.

The test added in the previous CL was broken due to a rebase on another
change. This subtly changed some of the byte offsets that broke the
test. This wasn't caught since I didn't rebase and re-run the tests
before merging.

This changes it from an OriginHandler to a MediaParser and moves the
handling of it to the Demuxer. This will allow more generic handling
of text by giving it the same abstractions as video/audio handling.
Change-Id: Ibbde3c84d228ec8e83af1ed266ea97dbc9589c24
In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample. This allows reading text streams from
the media files.
Change-Id: I6c00e286e98bc9aafe05b99cf2f7ce6f89d167a9
Instead of having the text readers reading from the file directly, they
now accept the data as a stream.

The Chromium sysroot has a broken C++11 implementation that doesn't
allow us to use <condition_variable> or <chrono>. So we need to use the
system sysroot to use all C++11 features.
