Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
- The official spelling of FFMPEG is FFmpeg (upper, then lower case).
- The normal vector copy and paste operators shoud be singular because
they can only be used on a single element.
- The "Parent File" file browser operator goes up one level in the
file hierarchy. It should be called "Parent Directory", like the
current description "Go to the parent directory".
- "Mass Vertex Group" used to define the mass, but was reused at some
point and now actually defines cloth pinning so it should be called
"Pin Vertex Group", as in the UI.
- The Transformation constraint's Map To Type suffered from a
typo (probably of -> on).
- "Fall-off" is more commonly spelled "Falloff".
- "Effected" should really be "Affected" in this case.
- Rephrase the descriptions for the curve painting tools drawing
plane, which did not seem to match what the settings do. Namely,
they allow selecting in which plane to draw curves using the Curve
Draw tool.

- Rename name/filename/path to filepath when it's used for full paths.
- Rename name/path to dirpath when it refers to a directory.
- Rename file to filepath or path (when it may be a file or dir).
- Rename ImBuf::name & anim::name to filepath.
Rename BLI_make_existing_file to BLI_file_ensure_parent_dir_exists.
The previous name read as if it would make (touch) the file,
where as it ensures the directory component of the path exists.
Move from BLI_path to BLI_fileops as path utilities should only
manipulate paths and not deal with file IO creation
(this has more in common with BLI_file_touch for e.g.).
Previously, having the "Encoding speed" set to "slowest" would choose
libaom-av1 first and librav1e second. This change makes Blender choose
librav1e first (and has a fallback to whatever other AV1 codec is
available if librav1e is not installed).
Addresses /T103849 on systems where librav1e codec available.

The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.
This changes does the following:
- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
which is a wrapper around sprintf() but without warning.
There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.

Seems like the new audio channel api was not as backwards compatible as we thought.
Therefore we need to reintroduce the usage of the old api to make older ffmpeg version be able to compile Blender.
This change is only intended to stick around for two releases or so. After that we hope that most Linux distros ship
ffmpeg >=5.0 so we can switch to it.

Previously, the Blender video renderer did not have support for
encoding video to AV1 (not to be confused with the container AVI).
The proposed solution is to leverage the existing FFMpeg renderer
to encode to AV1.
Note that avcodec_find_encoder(AV_CODEC_ID_AV1) usually returns
"libaom-av1" which is the "reference implementation" for AV1 encoding
(the default for FFMpeg, and is slow). "libsvtav1" is faster and
preferred so there is extra handling when fetching the AV1 codec for
encoding such that "libsvtav1" is used when possible.
This commit should only affect the options available for video
rendering, which includes the additional AV1 codec to choose from, and
setting "-crf".
Also note that the current release of FFMpeg for ArchLinux does not
support "-crf" for "libsvtav1", but the equivalent option "-qp" is
supported and used as a fallback when "libsvtav1" is used (as
mentioned here: https://trac.ffmpeg.org/wiki/Encode/AV1#SVT-AV1 ).
(Actually, both "-crf" and "-qp" is specified with the same value in
the code. When a release of FFMpeg obtains support for "-crf" for
"libsvtav1" is released, the code shouldn't be needed to change.)
The usage of the AV1 codec should be very similar to the usage of the
H264 codec, but is limited to the "mp4" and "mkv" containers.
This patch pertains to the "VFX & Video" module, as its main purpose
is to supplement the Video Sequencer tool with the additional AV1
codec for encoded video output.

Audio PTS was reset for each new file. This caused misalignment of video
and audio streams. In Blender, these files can't be loaded, other
players will fail to align audio and video.
Since timestamps are reset intentionally, reset also video stream
timestamps.
There were other bugs:
After timestamp was reset for audio, write_audio_frames started
encoding from timeline start until target frame, so each split video
had more audio than it should.
Also audio for last frame before splitting was written into new file.
Differential Revision: https://developer.blender.org/D13280
Before we didn't encode the audio up until the current frame.
This lead to us not encoding the last video frame of audio.

We didn't flush audio after encoding finished which lead to audio

In addition to this the audio timestamps were wrong because we
