Just play back any Verizon Media Dash Live stream for for 5 minutes or so and you will get infinite rebuffering

Basically after ~ 3 minutes shaka starts redownloading all slices after a certain slice after ever manifest update it gets to a point where it is downloading more than a dozen slices after each manifest refresh and then it starts infinitely buffering.

The fix for the
masterbranch key rotation issue has been merged. Everything should be working in the nightly build after tonight.The fix for the redownloading issue has been cherry-picked, but not yet pushed to v3.0.x until I can verify that all (29) cherry-picks for this branch so far are correct and passing tests. I have a few test failures to investigate before I can push those changes to that branch, but the fix will be out in v3.0.11 shortly afterward.
I performed a
git bisectto track down the fix inmasterthat is still needed inv3.0.x. At each step, I had to manually add back thefilter()call I mentioned that was removed in acfa1a8. This process revealed that the redownloading issue was fixed in 7e50866bb539ddd7e70ed6d6c245793b353262a6. We will cherry-pick this to v3.0.x, so this should fix the issue in v3.0.11.
