Support GPU->GPU changeType transitions |
|||||||||
Issue descriptionDue to the way that decoder fallback currently works, changing codecs while using the same decoder class does not work. Change DecoderSelector to support teardown and recreation of the same decoder class if the codec has changed.

Example case: 0. On Android, Chrome M70+ (or M69 with chrome://flags#enable-experimental-web-platform-features enabled) 1. https://rawgit.com/wolenetz/shaka-player/mse-codec-switching-demo-using-shaka-player/demo/#asset=https://storage.googleapis.com/shaka-demo-assets/angel-one/dash.mpd;lang=en-US;logtoscreen;debug;build=uncompiled;build=uncompiled;build=uncompiled 2. Select Load. Upon transition from H/W decode of vp9 (IIUC, vp9 H/W decode might only be done for some resolutions, e.g. >360p?, and perhaps only on some Android devices, at least including Google Pixel 2 XL) to decode of avc (only in H/W on Android) fails badly until this is fixed.

Until and unless media tracks work is shipped (not experimental) such that codec changes in src=media might occur, this may only be specific to MSE in Chrome.

This CL changes DecoderStream to maintain an instance of DecoderSelector continually. This enabled DecoderSelector to maintain DecryptingDemuxerStream state and the blacklist internally. An immediate consequence is that DecoderSelector can now always try the full list of potential decoders each time that selection is triggered.

It is no longer possible to loop forever doing fallbacks, so this is a robustness improvement in addition to being a requirement for changeType().

Sep 12
Need: 01f6f5cf6e9b78b3282a65c0a165bcbf90fde48d The production code change is basically just https://chromium-review.googlesource.com/c/chromium/src/+/1188978/6 (~200 lines), the rest is tests. We have full unit test coverage of this code, no reports of problems, and the change fixes multiple issues. It is not a trivial change, but we are confident in the changes and always intended for them to ship in M70. Want: 33473db6bafa29076fc1228d4b376f08bafed9f3 This is a trivial change on top of the previous commit to add metrics for MSE changeType() performance. It's not critical, but the risk is low.

Ping for merge-approval, this is required for broad ecosystem support of the AV1 launch.

Sep 14
Seems like this has been in canary for over a week. And is this behind a finch flag?

Sep 14
No, this is part of the default on AV1 launch and may affect other codec changes as well.

Sep 14
approving it for merge to M70. Can we closely monitor it next week during beta?

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/0e4fa12cb9ff909f981579e3d018a45d0f2f8153 commit 0e4fa12cb9ff909f981579e3d018a45d0f2f8153 Author: Xiaohan Wang <xhwang@chromium.org> Date: Wed Oct 03 21:08:50 2018 media: Add kFallbackAfterDecodeError feature This can be used to control whether to fall back to another decoder after audio/video decode error. This is useful in debugging and testing to avoid surprises, e.g. playback works after falling back to another decoder while the test doesn't expect a fallback. Bug: 877673 Test: Disable fallback on encrypted media (content) browser tests.
