In CL https://chromium-review.googlesource.com/c/chromium/src/+/1093995 (for issue 850679), I updated some of the EME browser tests to use mse_different_containers.html (as the tests need separate audio and video files which isn't handled by eme_player.html). The Android trybots (KitKat version, which doesn't support CBCS) were failing some of the new CBCS tests, so I've disabled those tests from running on Android for now.
However, the test doesn't handle all the failing conditions properly. In the examples below:
1. onSourceOpen is called twice
2. Uncaught InvalidStateError: Failed to execute 'endOfStream' on 'MediaSource'
3. Uncaught (in promise) NotSupportedError: Failed to load because no supported source was found.
4. Uncaught InvalidStateError: Failed to execute 'appendBuffer' on 'SourceBuffer'
5. content::Shell::PlatformSetTitle(): CLEAN
Opening this bug so that the failures can be checked and the test possibly updated to properly handle these errors.
