lgtm. Thanks a lot for addressing this! Good point about MidiManager::AccumulateMidiBytesSent releasing the lock too early, didn't notice the brace positioning. Looking at things again the Android/USB implementations post the task to the same message loop as the caller so this shouldn't have mattered there. What was the motivation for the Linux/Mac implementations having a separate thread handling these things?

The Mac and Linux code was earlier, the Android implementation came later, so there is likely a chance to go back and refactor/improve things for Mac and Linux. An example of this consolidation is at https://crbug.com/467442

LGTM. Let me push this CL to CQ now. I'll create separate CL to add comments, and rewrite or add TODO for AccumulateMidiBytesSent for other platforms. https://codereview.chromium.org/1500153002/diff/20001/media/midi/midi_manager.cc File media/midi/midi_manager.cc (right): https://codereview.chromium.org/1500153002/diff/20001/media/midi/midi_manager... media/midi/midi_manager.cc:156: client->AccumulateMidiBytesSent(n); Good catch. Can you add a comment here? We are likely to unlock any mutex before calling a callback as possible. Without any comment, someone may be revert this fix unexpectedly to avoid a potential deadlock.
