Some videos crashes the device and stucks in the boot phase. I guess it started after Mibox got the latest Android version. It wasn't happening with the OS it came with .
I uninstalled the updates to youtube (you can't uninstall the app) , clear the cache and reinstalled. it didn't change anything.
Is this a known problem, is there a solution for this?
I have reported many times to Xiaomi and YouTube but no answer. Xiaomi tried to fix the problem with 1 update. But I suspect the problem is from YouTube side. Your referred Certain videos are avc1 videos after you have play some VP9 videos and the next one is avc1 they crash device.
Mi box is capable to play avc1 and VP9 flawlessly. I switch to Smartyoutube TV, and it plays all without problems. During video playback you can even switch from VP9 to avc1 codecs back and forth without one crash. I play 35Mbit without one frame drop.
Make sure you report the issue and the links of the videos in the YouTube Feedback website, trust me, they've fixed all the issues I've reported: Youtube Feedback
use smartyoutube
Solution: Smart YouTube TV
