cartwheel : ffmpeg

Intel developer staging area for upstream patch contributions to FFmpeg.

The upstream project is tracked as a submodule in this repo.

upstream process

To improve upstream patch quality and reduce patchset rebase efforts, we use the following process

Send PR1 to https://github.com/intel-media-ci/ffmpeg, add module maintainers to Reviewers
Got approval from one maintainer
Wait for 1 more workday to see any objections. If it's an urgent issue, please ask another reviewer + 1 for you.
Close PR1, and send it to the community, ping the community with some frequency if it's no response.
If the community has no response in 4 weeks or it’s an urgent issue, send PR2 to https://github.com/intel/cartwheel-ffmpeg
Provide upstream patch link, ping maintainers for merging
Ping community until the patch merged in upstream

$ git commit -sam "$(git diff --submodule | head -1 | sed 's/:$//')"

...verify the patches still apply successfully. If they don't apply, fix them and include in new commit(s).
