anyone?
can you compare the output of 1.6.1 vs latest release in this case and see what might be different. Otherwise we'd probably need an input to reproduce this.

What is the expected result? DRM protected (Widevine) live stream should play well using ExoPlayer
What happens instead?
The stream works but freezes briefly when switching between different video bitrates. The freeze seems to last as long as the chunk length, in this case, 10 seconds. The problem is 100% reproducible and present only when the stream is DRM protected! The clear stream does not have this problem. Tested with different Exo Player versions (2.9.6, 2.13, 2.18.1)...
Also, tested exactly the same scenario with shaka packager 1.6.1 (which we also use in some production environments) does not have this problem.
