This embeds the full python protobuf library into the output in pssh-box-protos, which is used by installation targets and Docker images. Without this, the installed pssh-box.py tool would depend on a separate installation of the python protobuf library.

Support Dolby Vision profile 8.1, 8.2, 8.4, 10.1, 10.4 signaling in HLS
and DASH.
Adds new option `--use_dovi_supplemental_codecs` (off by default) to use
SUPPLEMENTAL-CODECS in HLS and `scte214:supplementalCodecs` and
`scte214:supplementalProfiles` for DASH.
To maintain compatibility with existing players the current behavior of
using two entries in the manifest remains the default. This will be
changed in a future version where `use_dovi_supplemental_codecs` will
become on by default.
Adds Dolby Vision compatible brands, 'db1p', 'db2g', 'db4g', 'db4h',
'dby1' based on https://mp4ra.org/#/brands

This PR adds parsing of teletext styling, and rendering of the styling
in output TTML and WebVTT subtitle tracks.
Beyond unit tests, I've used the sample
https://drive.google.com/file/d/19ZYsoeUfH85gEilQkaAdLbPhC4CxhDEh/view?usp=sharing
which has rather advanced subtitling with two separate rows at the same
time, where one is left aligned and another is right aligned. This
necessitates two parallel cues to be rendered. It also has some colored
text.
Solve #1335.
## parse teletext styling and formatting
Extend the teletext parser to parse the teletext styling and formatting.
This includes translating rows into regions, calculating alignment
from start and stop position of the text, and extracting text and
background colors.
The colors are limited to full lines.
Both lines and regions are propagated in the TextSample structures.
This is because the number of lines may differ from different sources.
For teletext, there are 24 rows, but they are essentially always
used with double height, so the number of output lines is 12
from 0 to 11.
There are also corresponding regions are denoted "ttx_R",
where R is an integer row number. A renderer can use either
the line number or the region ID to render the text.
## ttml generation for teletext to EBU-TT-D
Add support to render teletext input in EBU-TT-D (IMSC-1) format.
This includes appropriate regions ttx_0 to ttx_11 signalled
in the TextSamples, alignment and text and background colors.
The general TTML output has been changed to always include
metadata, layout, and styling nodes, even if they are empty.
EBU-TT-D is detected by the presence of "ttx_?" regions in the
samples. If detected, extra TTML elements will be added and
the EBU-TT-D linePadding used as well.
Appropriate styles for background and text colors are generated
depending on the color and backgroundColor attributes in the
text fragments.
## adapt WebVTT output to teletext TextSample.
Teletext input generates both a region with prefix ttx_
and a floating point line number (e.g. 9.5) in the
range 0 to 11.5 (due to input 0-23 as double lines).
The output is adopted to drop such regions
and convert the line number to an integer
since the standard only used floats for percent
values but not for plain line numbers.
They can still be skipped by passing `-DSKIP_INTEGRATION_TESTS=ON` for
the build configuration. Fix integration tests so they run correctly when building out of tree.
Use FindPython3 in CMake to fix build and integration tests on Windows.
The check for `!mpd_dir.empty()` is not needed because MakePathRelative
handles the case where the parent path is empty. As a result of this
check the base url, segment url, or segment template URLs were all
missing in cases where the mpd output was in the current working
directory.
Fixes#1378
The default .npmignore would disallow bin/, which contains binaries for
our NPM release. Every release before v3.0.3 was missing .npmignore, and
therefore had no binaries. These were unusable in NPM, and have been
marked as deprecated because of it.
Closes#1369
The release workflows did not run checkout with `fetch-tags: true`, so
the builds were unable to compute the correct release version number. I
audited all instances of `actions/checkout` to add `fetch-tags` where
needed and clean up unneeded options.
I also had to fix options to `docker/build-push-action`, which by
default ignores `actions/checkout` and tries to pull from git itself.
This led to the Docker build running in a context without the new tag.
Finally, to make verification easier and provide version info in the
build logs, this adds debugging info to the version-generation script
via stderr.
Closes#1366
Support for this came out in January, 2024. Explicit macos versions seem
to be necessary for now, until GitHub offers "latest" labels targeting
specific architectures.
Use the second sample in mp4 and webm formats. #835 had issues with
merging due to golden file conflicts. Because we cannot make dependent
pull requests, this is a replica of #835.

Fixes#1356 which was caused by the fix in #1281 which updated this to
use the correct FairPlay system ID. However since old versions
recognized the previous system ID this restores support for it to avoid
breaking clients.
This adds the option FULLY_STATIC to create fully-static executables.
To create portable, fully-static release executables on Linux, we need
to use musl instead of glibc. Static executables from glibc are not
portable.
The popular musl-gcc wrapper does not support C++, so instead we use a
full musl cross-compiler toolchain in the build workflow.
To build FULLY_STATIC, the user must point to the appropriate
cross-compiler, as we do in the workflow. On systems where musl is the
native libc (such as Alpine Linux), this is not necessary.
I have also read that musl's allocator is not very fast in
multi-threaded applications. So when FULLY_STATIC is enabled, we will
also enable mimalloc, a replacement allocator that is very fast.
I tested a very basic packaging command to compare speeds of dynamic
glibc, static musl, and static musl+mimalloc:
dynamic glibc:
runs: 2.527, 2.798, 2.703, 2.756, 2.959
avg = 2.749, std dev = 0.156s
static musl:
runs: 2.813, 2.920, 3.129, 3.003, 2.738
avg = 2.921s, std dev = 0.154s
static musl+mimalloc:
runs: 2.291, 2.034, 2.415, 2.303, 2.265
avg = 2.262s, std dev = 0.140s
The mimalloc build is 82% faster than musl default allocator, 77% faster
than glibc, and has more consistent runtime characteristics (lower
standard deviation).
We already disabled warnings-as-errors in third-party code, but this
goes futher to completely disable third-party warnings. They are mostly
noise, and distracting. If they aren't errors, we shouldn't have our
build logs flooded with them.
This tweaks the default config for stderrthreshold from absl/log so that
we always get logs to stderr by default, as we did in v2. The --quiet
and --v flags that existed in v2 can still be used to modify the log
level, as well as the new --minloglevel from absl/log.
Issue #1325
An updated version of PR #1027
That previous PR was done using 2021 code, and there were many changes
in the codebase from there, so a rebase was needed and also some minor
tweak here and there. But it's the same code, just reimplemented on a
newer codebase.
If you want to take a look at this in action, after building shaka
packager with this PR's code included, try this commands in 3 different
simultaneous bash sessions:
1. Video UDP input: `ffmpeg -f lavfi -re -i
"testsrc=s=320x240:r=30,format=yuv420p" -c:v h264 -sc_threshold 0 -g 30
-keyint_min 30 -r 30 -a53cc 1 -b:v 150k -preset ultrafast -r 30 -f
mpegts "udp://127.0.0.1:10000?pkt_size=1316"`
2. WebVTT UDP input: `for sec in $(seq 0 9999) ; do printf
"%02d:%02d.000 --> %02d:%02d.000\ntest second ${sec}\n\n" "$(( ${sec} /
60 ))" "$(( ${sec} % 60 ))" "$(( (${sec} + 1) / 60 ))" "$(( (${sec} + 1)
% 60 ))" ; sleep 1 ; done > /dev/udp/127.0.0.1/12345`
3. shaka packager command line: `timeout 60
path/to/build/packager/packager
'in=udp://127.0.0.1:10000?timeout=8000000,stream_selector=0,init_segment=240_init.m4s,segment_template=240_$Number%09d$.m4s,bandwidth=150000'
'in=udp://127.0.0.1:12345?timeout=8000000,stream_selector=0,input_format=webvtt,format=webvtt+mp4,init_segment=text_init.m4s,segment_template=text_$Number%09d$.m4s,language=eng,dash_roles=subtitle'
--mpd_output ./manifest.mpd --segment_duration 3.2
--suggested_presentation_delay 3.2 --min_buffer_time 3.2
--minimum_update_period 3.2 --time_shift_buffer_depth 60
--preserved_segments_outside_live_window 1 --default_language=eng
--dump_stream_info 2>&1`
Note the added `input_format=webvtt` to the shaka packager command's
second selector. That's new from this PR. If you don't use that, shaka's
format autodetection will not detect the webvtt format from the input,
as explained in
https://github.com/shaka-project/shaka-packager/issues/685#issuecomment-1029407191.
Try the command without it if you want to.

This is based on comments at
https://github.com/google/shaka-packager/pull/891. The muxer is deciding
whether to write to a single file or a segment file based on the
configuration.

```
../packager 'in=TOS.ts,stream=video,output=tos_video.ts,playlist_name=tos_video.m3u8' \
'in=TOS.ts,stream=audio,output=tos_audio.ts,playlist_name=tos_audio.m3u8' \

In some cases it can happen that the http server responds with a
non-successful status code without reading the response body. In this
case curl may decide not to read from the cache since there is really no
point in sending data to the server. In case some other thread of shaka
has already called HttpFile::Flush it may end up deadlocked there
waiting for the cache to either close or become empty. Thus, we close
the cache when leaving the main thread as no data will be read by curl
after it has finished anyways.
Closes#1347
adds an optional `--hls_start_time_offset` parameter, that, when
used, adds `EXT-X-START` tags to the HLS media playlists.
The EXT-X-START tag allows to specify the location where the player
starts playing, either from start (positive value) or from end (negative
value).
This is especially useful in case of livestreams where this tag can be
used to set the target latency of the playback.
Reference: https://datatracker.ietf.org/doc/html/rfc8216#section-4.3.5.2
The RFC says, that the `EXT-X-START` tag could also be added to the
master playlist, but my tests have shown that most players only respect
it when it's in the media playlists.

ISO/IEC 14496-15 says about the `HEVCDecoderConfigurationRecord`:
> **array_completeness** when equal to 1 indicates that all NAL units of
> the given type are in the following array and none are in the stream;
> when equal to 0 indicates that additional NAL units of the indicated type
> may be in the stream; the default and permitted values are constrained
> by the sample entry name;
This PR sets `array_completeness` to 0 if parameter NAL units may appear
in the stream when they are not stripped by
`--strip_parameter_set_nalus`.
This should increase player-compatibiltity for streams with mid-stream
SAR changes.
