AreWeCompressedYet is an automatic service for compressing videos with AV1, VP9, Daala, Thor, and other codecs.

It generates graphs using different metrics, to enable comparisons between different versions of codec source code.

For bugs and enhancements, see its GitHub Issues page.

  • Run ID - A unique name for the run, prefilled with date.
  • Git Commit Hash - The hash of the commit to be tested. This must be visible either on Gerrit or a specially installed personal repo. This is the "Commit" on Gerrit and not the Change-Id or tree hash.
  • Codec - Selects both Codec and default options.
  • Set - videos to run.
  • Extra CLI options - Passed to encoder binary along with the defaults. Usually not needed.
  • Extra build options - Passed to configure script. For AV1, pass flags to enable experiments here. (for example, --enable-experimental --enable-feature)
  • IRC nick - Name to notify on #daala, also for sorting runs.
  • Custom qualities - optional, specifies quantizers to use instead of the defaults.


Command-line tools


 DAALA_ROOT=./ --help

You must have a secret_key file in the current directory, containing your key to access AreWeCompressedYet.

By default, the prefix used for the run is your local branch name.

Internal tools

  • the backend server process.
  • an alternate way to invoke the same tests as, it's no longer maintained and may be broken. This was used by previous versions of AWCY, and can only run one test at a time.
  • A script called by, contains the command line parameters for all testable codecs.

Output Format

For an explanation of AWCY's metrics output format, see the RD_Curve_Data_Format page.


The server is a CentOS 7 virtual machine running on There are few config file changes, so the CentOS machine should be easily upgradeable to get security fixes.



The AWCY server has a unit file at /etc/systemd/system/awcy.service. It listens at localhost:3000.


The backend has a unit file at /etc/systemd/system/rdserver.service. It listens at localhost:4000. It currently has no authentication and should not be exposed to the Internet.


NGINX is configured to be a TLS endpoint and proxy_pass to localhost:3000. Certificates are managed by the EFF's certbot and issued by Let's Encrypt.


Firewalld is configured to allow ports 22, 80, and 443 only.


Chrony is required to keep the system time in sync. Amazon Web Services signatures require an accurate system clock.
