It appears that not all Apple implementations follow the HLS guidelines.
While the DEFAULT=NO for an audio track should be optional and default
to NO, in practice native HLS players Safari and iOS devices treat the
missing DEFAULT as a MAYBE.
Fixes#1169
Legacy players, e.g. older versions of ExoPlayer, do not handle default webvtt text alignment correctly. Need to specify `align:center` explicitly cues without text alignment for backwards compatibility.
Fixes#925.
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.

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.

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 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.

The KeySource now only handles fetching the keys and loading any PSSH
info from the license; it will not handle generating new PSSH info
based on the config.
This will allow the PSSH generation to access to the full
EncryptionConfig so we can add additional options to it.
Issue #756
Change-Id: Ia67387aa3d5ec0d723b7f5f21fc517f64c840393
Added --crypt_byte_block, --skip_byte_block to allow users to specify
protection pattern other than 1:9 for pattern based encryption scheme,
e.g. cbcs and cens.
Closes#710.

Change-Id: I9f64a7639170c737f138572689b28d17286325c7
Added Dolby Vision backward compatible signalling, i.e. for Dolby Vision
profile 8, both base codec without Dolby Vision and HDR codec with Dolby
Vision are signalled.
This is achieved by using a new MuxerListener implementation
MultiCodecMuxerListener, which wraps multiple child MuxerListeners and
is able to delegate to the child MuxerListeners based on the codecs in
the stream.
Closes#341.

For MP4 files, mp4 parser tries to open and read the same file again
to handle trailing MOOV box.
Open FIFO again may result in packager hang.
Update the code to only attempt to load MOOV for local regular files,
as FIFO and remote files are unseekable anyway.
Fixes#664.

Although FRAME-RATE is optional per HLS specification, but per HLS
Authoring Specification for Apple Devices (https://apple.co/30n90DC):
Each EXT-X-STREAM-INF tag MUST have a FRAME-RATE attribute.
Also, iOS and TVos refuse to play the content if VIDEO-RANGE is
present but FRAME-RATE is missing.
Issue #632, #634.

- Parse and extract transfer_characteristics from H264/H265 VUI
parameters.
- Set VIDEO-RANGE attribute in HLS according to HLS specification:
https://tools.ietf.org/html/draft-pantos-hls-rfc8216bis-02#section-4.4.4.2
- Also added an end to end test.
Fixes#632.
Change-Id: Iadf557d967b42ade321fb0b152e8e7b64fe9ff3e
- Add relevant FOURCCs for Dolby Vision.
- Parse DOVIDecoderConfigurationRecord (dvcC, dvvC) to generate
Dolby Vision codec string.
- Propagate Dolby Vision configs (dvcC, dvvC, hvcE) from Demuxer
to Muxer.
- Add a Dolby Vision end to end test.
Support for backward compatibility signaling in DASH and HLS will be
added in a later CL.

Add dash_accessibilities stream descriptor, which is a semi-colon
separated list of accessibility_scheme_id_uri=value. It is optional.
Add dash_roles stream descriptor, which is a semi-colon separated
list of strings. It is optional.
Closes#565.

We have logics in bandwidth calculation to ignore segments that is
smaller than half of target duration. The logic does not have any
effect right now as the target duration in mpd/hls params is always
zero.
This change will set target duration in mpd/hls params, thus it can fix
part of issue #581 as the last segment which is less than half of
target duration.
Issue #581.
Fixes#498.

Generate an audio only master playlist if there are no videos and
subtitles.
We do not support mixing audio only EXT-X-STREAM-INF with video
EXT-X-STREAM-INF right now.
Fixes#461.

Add hls_characteristics stream descriptor, which is a colon or semi-colon
separated list of strings. It is optional.
Fixes#430.

Only Marlin Adaptive Streaming Specification – Simple Profile is
supported.
Two additional updates:
- Remove FairPlay ContentProtection element from DASH mpd as FairPlay
does not define a signaling in DASH.
- Updated end to end test to include all DRMs we support.
Closes#381.
