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.

The newest pylint release complained about several issues that the
older release did not. This resolves those issues:
- removes unneeded "u" prefix from strings
- adds "encoding" parameter for all open() calls
- because "encoding" is a python3-only parameter, use python3 in all
the scripts that we control
Unfortunately, python2 is required for any scripts that import modules
from the ancient Chromium build system we're using (referenced by
DEPS), as well as kokoro scripts.

Internal CI systems and the new GitHub CI system were out of sync,
with the external system not doing any linting. Further, the internal
system was using an internal-only linter for Python.
This creates a script for Python linting based on the open-source
pylint tool, checks in the Google Style Guide's pylintrc file, creates
a custom action for linting and adds it to the existing workflows,
fixes pre-existing linter errors in Python scripts, and updates pylint
overrides.

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.

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.
Issue #177
Change-Id: I10e1084dac77841220161fbd2575cdcb5c13c00e
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.
Change-Id: I6f7edda09e01b5f40e819290d3fe6e88677018d9
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
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.

If the user has the GPAC MP4 tools installed, this will use that to
provide a better, text-based diff of the MP4 files. This makes looking
at test failures much better than just "binary files differ".
Change-Id: Ifdca54c02226a9f0fe9ddcf9c6b28e960e568111
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.
Change-Id: I1967bb1ed503087cdd011c364e5fb5647d516ca4
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.

- 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.
Change-Id: Idb1c20bb410fdd016db07e11fe507c102a3dd8ea
Addresses binary/str conversion problems like
'can't use a string pattern on a bytes-like object'.
With this change, packager_test.py will work with any version of python
after python2.5.
Fixes#553.
Change-Id: I02066942e4bcdddc1db1daf761abab4cc46169a9
Add hls_characteristics stream descriptor, which is a colon or semi-colon
separated list of strings. It is optional.
Fixes#430.
Change-Id: Ifcf79316e68768ff065891933de565cd0ff32ec4
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.
Change-Id: Id12269b471ea34983b782cbd92f687332292ef59
This was introduced earlier to indicate FairPlay protection system. But
in fact, it is sufficient to just use the system id for the indication.
- Also updated various parts of the pipeline to support empty PSSH.
- Added an additional FairPlay end to end test using fMP4.
Change-Id: Ica48b7b5235e9a2b5a7f722bcd0fc1ef2073ac13
Note that TTML in ISO-BMFF is not supported yet.
Also updated packager_test.py:
- Added a test using TTML passthrough.
- Computed output extension from input extension unless output_format
is specified.
Fixes#478.
Change-Id: Ia917fc4ed3c326782791ed67601fba02ea28b11d
The time for the previous segment was used when generating the segment
name. This resulted in the first segment being overwritten and
mismatching manifest and media files. It led to playback problems.
Issue #472.
Change-Id: Ia8130ce261585e1a2ede83b26de3e32508de087f
Implemented per AV1 Codec ISO Media File Format Binding at
https://aomediacodec.github.io/av1-isobmff/
And AOM AV1 codec mapping in Matroska/WebM at
https://github.com/Matroska-Org/matroska-specification/blob/av1-mappin/codec/av1.md
Note that AV1 specific boxes are not supported in this CL, i.e.
AV1 Forward Key Frame sample group entry 'av1f', AV1 Multi-Frame
sample group entry 'av1m' etc are not supported. These boxes are optional.
We will add support later if they are useful to the clients / players.
Encryption is not supported yet.
Issue #453.
Change-Id: I630432d0a9bf82d263ffaf40e57f67fc65eee902
Configurable with --transport_stream_offset_ms.
This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.
Issue #112.
Change-Id: I0fce8766c9df2911b9bb859c1e54052a8ed2abfb
In some ISO-BMFF files, there is an initial non-zero composition offset,
but there is no EditList present.
This is against ISO-BMFF spec recommentation [1] and we believe in most
cases it is just missing the EditList.
[1] 14496-12:2015 8.6.6.1
It is recommended that such an edit be used to establish a presentation
time of 0 for the first presented sample, when composition offsets are
used.
Issue: #112.
Fixes: b/110782437.
Change-Id: I23d33810ce536b09a1e22a2644828d824c1314f5
MPD cannot be validated right now since we do not generate deterministic
mpd with multiple inputs due to thread racing.
Exclude mpd comparison in this case.
