Shaka Player (https://github.com/google/shaka-player) discovered that calling abort() on Safari's SourceBuffer causes a decoder error.
In our test, we append several segments, then call abort() and append several more. The abort() call should reset the decoder's timestamp, but instead causes a complete failure.
To reproduce:
1. Visit http://storage.googleapis.com/shaka-demo-assets/_bugs/safari-abort/index.html in Safari
2. Open the JavaScript console
3. Observe failures instead of playback
In Chrome, Firefox, Opera, Edge, and IE 11, the result is that the video plays.
In Safari 9, nothing plays and there are several errors in the JS console:
MSE OPERATION FAILED
VIDEO ERROR - MediaError {code: 3}
EXCEPTION - Error: InvalidStateError: DOM Exception 11
OS X El Capitan, Safari 9.0.3 (11601.4.4) and in WebKit nightly r203816.

This is not reproducible on Safari 10.
