Bug 1314147 - Port the libvpx mozbuild generator to aom. r=froydnj,kinetik
This is a port of the libvpx scripts, themselves a port of Chromium's scripts to generate an external build description using hooks in the upstream configure and make scripts. The libaom library is a fork of libvpx so we can use a similar approach. I've put the upstream source in $(topsrc_dir)/third_party/aom but the build description and any patches are under the media directory with the other codecs, similar to how zlib works. Config files and headers generated by the upstream build system are also under $(topsrc_dir)/media/libaom/.

This directory contains build files for the aom video
|
||||
codec reference implementation. The actual library
|
||||
source is in $TOPSRCDIR/third_party/aom/
|
||||
|
||||
Any patches or additional configuration to be applied to the
|
||||
upstream source should be kept here in the media/libaom
|
||||
directory.
|
||||
|
||||
To update the library source and build config files, execute
|
||||
|
||||
./mach vendor aom
|
||||
|
||||
To update to a specific upstream git tag or commit, use
|
||||
|
||||
./mach vendor aom -r <commit>
|
||||
|
||||
The upstream aom git repository is:

||||
