  • If custom app, can you reproduce the issue using our demo app? Yes

• What did you do? Drm encrypted video content with multiple audio and 6 bitrates.

  • What content did you load? Drm encrypted video content with multiple audio and 6 bitrates

    • If standard demo asset, which one?

    • If custom asset, what manifest and license server URIs?

  • How did you interact with the content, if at all?

• What did you expect to happen? It should be playable smoothly

• What actually happened? The player can buffer without problems and it has enough buffer to play but in every 5-15 seconds it pauses 0.1 - 1 seconds on low-end machine.

Core 2 duo 2 Ghz 2 Gb Ram Windows 8 Chrome 55 with or without hardware accelerated.

There no problem on high-end machines.

Thank you.

We have never had enough data to determine a good threshold for dropped frames. This is the main reason our default AbrManager does not account for dropped frames yet. It’s something we’d like to be able to offer, though.

@ToreJuloe, thanks. I’ve filed https://github.com/google/shaka-player/issues/745 to track any efforts we make in future on using dropped frames for ABR feedback. I’ll go ahead and close this issue now.
