This directory contains build files for dav1d. The actual library
source is in $TOPSRCDIR/third_party/dav1d/
Any patches or additional configuration to be applied to the
upstream source should be kept here in the media/libdav1d
directory.
To update the library source and build config files, execute
./mach vendor dav1d
To update to a specific upstream git tag or commit, use
./mach vendor dav1d -r <commit>
The upstream git repository is https://code.videolan.org/videolan/dav1d
To update to a fork, use
./mach vendor dav1d --repo <repository url> [-r <commit>]
The rough steps are:
- Execute ./mach vendor dav1d -r {tag-name} # ex: ./mach vendor dav1d -r 0.6.0
- Update moz.build with the new files, check the
third_party/dav1d/src/meson.build (confirm with the diff) (note the
empty .asm file in x86_64)
- Build a stand-alone libdav1d following the steps here:
https://code.videolan.org/videolan/dav1d#compile
- Copy vcs_version.h from the local build/include/vcs_version.h
to media/libdav1d/vcs_version.h
- Copy version.h from local build/include/dav1di/version.h to
media/libdav1d/version.h
- Update dav1d.rc:
- update the API_VERSION_NUMBER, API_VERSION_NUMBER_STR, defines to
match the 'dav1d_soname_version' field in
third_party/dav1d/meson.build.
- update the PROJECT_VERSION_NUMBER, PROJECT_VERSION_NUMBER_STR
defines to match the new project versions from the git tag (or from
the project version found in third_party/dav1d/meson.build).
- Add new options, if any, in moz.build or config.h
Tips:
- If you see build failures in build-linux64-base-toolchains (or
similar jobs) dav1d may now require a higher minimum nasm version
than our base toolchains currently support. A bug updating the
minimum nasm version will probably be necessary.
