This patch moves FFMPEG building to buildbots:
- `ffmpeg-mac.zip` is built on Mac 10.14 machine
- `ffmpeg-win32.zip` and `ffmpeg-win64.zip` are cross-compiled on
Ubuntu 20.04 machine
All builds across the platforms share the same config:
- the same versions of `ffmpeg` and `libvpx`
- the same build configuration for both `ffmpeg` and `libvpx`
The config could be found in the `//browser_patches/ffmpeg/CONFIG.sh`.
The builds will be then copied manually and committed to the git
repository.
Originally there was no way to build both webkit-gtk and webkit-wpe
in the same checkout. As a result, we were:
- building webkit-gtk & uploading it to CDN
- building webkit-wpe & uploading it to CDN
- downloading webkit-gtk & webkit-wpe from CDN and compiling a single
webkit-gtk-wpe folder that we uploaded to CDN
As of today, however, we can build WPE and GTK ports together. This
patch starts using this to drastically simplify build process:
- build webkit-gtk and webkit-wpe
- use `archive.sh` script that compiles a single folder with both ports
- upload archive to the cloud
This should also fix currently failing webkit build that fails to
assemble the `webkit-gtk-wpe` folder (I missed these codepaths while preparing
for Ubuntu-20.04 bot).
