I have a Galaxy Tab 10.1 (a.k.a. p4, P7500), running Android 4.2.2 rooted (latest CyanogenMod nightly build: 10.1-20131208-NIGHTLY-p4) and YouTube v5.3.28.
Does anyone have an idea how to improve the performance of the video playback?
What I'm experiencing is a lot of stutter: videos often only show a few frames per second (the audio seems to get priority and plays fluidly). Sometimes videos pause for a few seconds at a time. I'm testing with preloaded, fully cached videos, so it's not a problem of network connection. Killing background tasks helps a little bit when it's really bad, but doesn't fix the problem entirely.
Now I know this isn't exactly a high-performance device, but when playing them with MX Player, all 720p videos are playing absolutely fluidly without a single stutter. This also includes the exact same videos that stutter in the YT app after downloading them and playing them with MX Player. So the device is capable of playing back those videos perfectly fine.
Any ideas what I could try to increase the YouTube app's performance?
