This will force the muxer to order streams in the order given on the
command-line.

This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

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
Always set AUTOSELECT=YES for DVS tracks and also exclude it from
standard AUTOSELECT and DEFAULT configuration logic.
Fixes#857.

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.
Change-Id: Ica282f023a7e8538f7b506094e2286840cf5c193
Calculate FRAME-RATE from sample duration as in the DASH solution.
Right now calculated frame-rate may not be accurate in some scenarios,
so we avoid setting the attribute in HLS unless it is more than 30
fps. We will set it unconditionally once it is fixed.
Fixes#634.
Change-Id: I87b6e9a047d959ae88dd4dcb2b4786527ba5c9fc
- 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.

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.

It allows users to override the default language for text tracks.
If not specified, --default_language applies to both audio and text
tracks.
Issue #430.
Change-Id: I86a9baba2072be27b6661fa7b65a8bc8b6adb3cc
Add hls_characteristics stream descriptor, which is a colon or semi-colon
separated list of strings. It is optional.
Fixes#430.
Change-Id: Ifcf79316e68768ff065891933de565cd0ff32ec4
Having "wvtt" in the codec string (in the master playlist) causes
errors on some older Apple products. As including it is optional,
we are opted to omit it to ensure support for all Apple products.
Close#402
Change-Id: Ib1072bcc26a3ff66e3a6d3204789c0c8c678d4db
Two-character ISO-639 code in --default_language was ignored due to
a bug in language code matching as the language code in stream is
always converted to 3-character code.
Fixes#371.
Change-Id: I8618938af583a417446636ff9efe1c72ce822c33
This change has the hls master playlist add the text codec string
to the list of codecs in a variant.
Bug: 72942756
Change-Id: Ib25bb2064a291d10d7b1d261a4307991df62220c
- Add empty lines between different types of renditions to improve
readability.
- Group variants with the same audio/text group together, as it is
where the Adaptation occurs.
- Write master playlist after writing media playlists. This makes
more sense and it is also necessary to have the bandwidth of
the last iframe playist segment correctly computed.
- For fMP4, I-Frame segment must include the 'moof' header.
- Fix a problem that hls_iframe_playlist_name is not passed to
MuxerListenerFactory.
Issue: #287
Change-Id: Icf37c5de1dc29f85ae3f419cbc3264d04ca491a4
Took the same logic for DEFAULT and AUTOSELECT used by audio and
applied it to text. Combined the build tag logic for audio and
text as they were the same expect for a couple fields.
Bug: #205
Change-Id: I75ecbf4b25cd559b826982d12a5b132e70b83b69
The master playlist and media playlist did not have implementations
for handling text streams. This change adds support for both.
Bug: #205
Change-Id: I1329b8cc2585f15b89959071db9dd16d35847cba
If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.
Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.
Bug: #205
Change-Id: Iefc8bfd35708286619d0004348294d98f2c38482
In the master play list, use a class called variant to build
the video tags.
The variant list will always have one entry. In the case that there
are no audio streams, the variant list will have a null entry.
Bug: #205
Change-Id: I6e4acd83a31cd267c173e4f4c910f93781fe6efd
According to HLS spec: https://goo.gl/MiqjNd 4.3.4.1.1. Rendition Groups
- A Group MUST NOT have more than one member with a DEFAULT attribute of
YES.
- Each EXT-X-MEDIA tag with an AUTOSELECT=YES attribute SHOULD have a
combination of LANGUAGE[RFC5646], ASSOC-LANGUAGE, FORCED, and
CHARACTERISTICS attributes that is distinct from those of other
AUTOSELECT=YES members of its Group.
We tag the first rendition with a particular language in an audio group
with 'AUTOSELECT'; it is tagged with 'DEFAULT' too if the language
matches --default_language.
Fixes#315
Change-Id: Iacc0bc8c89ebffce8717fa65e82d6daf5a1f6adc
As specified in HLS spec (https://tools.ietf.org/html/rfc8216):
All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute. If a
Master Playlist contains two Renditions encoded with the same
codec but a different number of channels, then the CHANNELS
attribute is REQUIRED; otherwise, it is OPTIONAL.
Fixes#299
Change-Id: Ic2308c39b170178b11cb0d94c3a8083c8b5f3353
- The master playlist should have the display resolution instead of the
encoded resolution.
- Changed MediaPlaylist to return display resolution.
Change-Id: I162727d0bdeed0302518286e42a22b69a58fc4a3
In the original manifest updating process, the file was truncated first
before was written with new contents. There is a small chance that
the web server may read back empty file or incomplete file.
The new code makes the update operation atomic (by writing to a temporary
file first then replace the old file with the temporary file).
Fixes#186
Change-Id: I2fd564cb12b922b032c0e9f70d2132a5b12ff098
Resolving TODO in packager/hls/base/master_playlist.cc that asked for
media playlists to be grouped when they are added.
Change-Id: I01c7687400bc74ce45f271d0242d1c3bf3610cf2
The HLS manifests output by the packager did not have the RESOLUTION
attribute on EXT-X-STREAM-INF tags. This change adds the resolution
tag when resolution values are present.
Close#235
Change-Id: I15ca6de47cb34793cf6a940123d593261627baa4
Before this, HLS output did not contain language information.
Now, media playlists are properly tagged with a language in the
master playlist.

- The current implementation only handles VOD.
- Add #EXT-X-PLATLIST-TYPE.
- For VOD Add #EXT-X-ENDLIST at the end.
- Append comma at the end of EXTINF.
Change-Id: I16f01da66f8bbf0229395cb380fa125ffd9328a8
- Media Playlist that is non-VERSION 1 must have EXT-X-VERSION.
- Attribute for EXTINF should be CODECS instead of CODEC.
- BANDWIDTH attribute expects bitrate (not bytes per second).
- Removed unnecessary check if MediaInfo has media_info_name, in
SimpleHlsNotifier::NotifyNewStream().
