Chromecast dropping frames while buffering for higher quality streams #494

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1.Start Netflix/Hulu
2.Stream any video (or Netflix test video 
http://www.netflix.com/WiMovie/70136810?trkid=439131)
3.Observer playback smoothness during panning scenes

What is the expected output? What do you see instead?
Playback should be smooth but it appears as dropping frames.

What version of the product are you using? On what operating system?
Chromecast on LG TV LM670S using Nexus 7 HD 5.0.2/HTC M8 5.0.1.

Please provide any additional information below.

This is clearly a bug, as this issue is fixable by Play/Pausing the video 2-3 
times (you don't have to wait, just play/pause repeatedly). Tested myself and 
it instantly fixes the problem in Netflix and Hulu.

Found this solution here:

Without the Play/Pause trick it appears as if Chromecast is dropping frames 
while buffering in the background for the higher quality streams. Usually after 
3-5 minutes, this effect disappears. While this is OK for Netflix, in Hulu you 
get commercials that interrupt the streaming so this happens again and again.

I don't experience this problem in YouTube.

After playing video for 1-2 hours the issue started to also reproduce on 
YouTube. I think there is something with the base chromecast player 
implementation because the issue does randomly reproduce across the majority of 
services.

On YouTube is started to do this when both iPad and HTC M8 where connected. I 
think that by simply communicating with more than one device at the same time 
it makes the chromcast drop frames.
