1215257 - HTML <audio> throws error code 3 (MEDIA_ERR_DECODE) running gaia integration tests in automation

Status: RESOLVED WONTFIX

(Firefox Build System :: Task Configuration, task, P2)

Description

[Justin D'Arcangelo [:justindarc]]

While tracking down the cause of test failures from the patch in Bug 1149930, it seems that the <audio> element cannot play OGG or MP3 files on Treeherder in the Gaia integration tests for Music. This does not reproduce when running marionette-js locally on Linux unless you specify the `PULSE_AUDIO=":"` flag. If you run the Gaia integration tests for Music with the `PULSE_AUDIO=":"` flag on a local Linux machine, the exact same test failures are reported as on Treeherder.

The only thing the patch in Bug 1149930 does is listens for the 'error' event on the <audio> element and skips ahead to the next song in the queue if it is encountered. When running on Linux with the `PULSE_AUDIO=":"` flag, the 'error' event is thrown for every song played which causes unpredictable state in the integration tests.

Treeherder is a dashboard for displaying results. It has nothing to do with how said results were created :). Moving this over to the Taskcluster product since it sounds like a machine config issue.

See gaia try run here: https://treeherder.mozilla.org/#/jobs?repo=gaia&author=[e-mail]

Things looking really good. Will remove :justindarc's commit before pushing.

What did you change?

I recently discovered in bug 1214809 that pulseaudio doesn't actually start in the taskcluster/tester image.  Did you do something to fix that?

Looks like Gij11 is still failing.

Actually, still really broken. Trying some other avenues now.

I've tried some of the easy fixes to no avail. I am actively working on this but I don't really have an ETA at this time.

These tests are running as root, correct?

If not, I discovered in bug 1214809 that using 'su' to drop root privileges causes pulseaudio to crash docker, and 'sudo -E -u worker' works a lot better.

Marking it a P1 as it blocks a P1 bug for 2.5+

Sorry Justin, I'm completely swamped, I currently have no idea when I'll get to this.
