We have detected a build metrics regression from push: https://hg.mozilla.org/integration/autoland/pushloghtml?changeset=a344042d76e92e824f153da614d6571d63a2c71b As author of one of the patches included in that push, we need your help to address this regression. Regressions: 3% build times summary linux32 pgo taskcluster-c4.4xlarge 2,940.39 -> 3,014.01 1% compiler warnings summary linux64 asan asan debug 380.92 -> 385.17 You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=7135 On the page above you can see an alert for each affected platform as well as a link to a graph showing the history of scores for this test. There is also a link to a treeherder page showing the jobs in a pushlog format.

We added a new 3rd-party library, so I'm not surprised by the build time increase. (But only on linux32 pgo?) Warnings we can fix.

Just saw an installer size alert show up for this revision: == Change summary for alert #7135 (as of June 08 2017 21:27 UTC) == Regressions: 3% build times summary linux32 pgo taskcluster-c4.4xlarge 2,940.39 -> 3,014.01 1% installer size summary linux32 opt 59,684,253.08 -> 60,392,248.42 1% compiler warnings summary linux64 asan asan debug 380.92 -> 385.17 For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=7135 Letting :sylvestre know so he can track this.
Can we build/ship only the part that we use in aom? (if it is not the case)
We're currently using only the decoder, so I could try patching out the encoder until we need it for the WebRTC and MediaRecorder APIs. However, this is a nightly-only experiment; the regression should be resolved by the code turning off entirely when Firefox 55 goes to beta.

Priority: -- → P3
This change is nightly-only so it shouldn't affect Firefox 56 or 57 once it goes to beta.
Same story through Firefox 60; this is still nightly-only code.
