I am currently using Android Revolution HD 6.5.1 XE on my Sensation and I have several major problems:
1. I realize that 1080p mkv videos that my phone can play smoothly on Gingerbread (including Youtube HD 1080p) now become laggy. Even with SD videos (fully HW accelerated), sometimes the playback is choppy as well (I use MX player and Dice player). Can anyone help me confirm whether you have the same problems? I believe ARHD ICS does not have GPU overclocked as on Gingerbread, hence the choppy video playback.
2. On random occasions, I cannot get any sound on any applications, but notification sounds and stock music player are working normally. I can still listen to music through the stock player but cannot get any sound for videos. Everything will return to normal when I restart the phone.
3. Wifi randomly turns on by itself. The last time I check, this problem seems to be unsolved, but I may be wrong.
Any kind souls willing to give me some directions to solve the above problems? ARHD Gingerbread ROM does not have any of the problems above, but I don't want to go back to Gingerbread.
I have tried flashing the ROM 3 times (also redownload the ROM, check md5), with both stock kernel and Sebastian's kernel (at 1.2, 1.5, 1.7 Ghz) and the video playback is still quite bad. I just flash the latest 6.5.2 on my Sensation and it is still the same problem with video playback. Just to confirm, can you guys watch 1080p youtube hd video without any problems?
The playback problem disappear straight away when I go back to GB.
Hey man, in MX player, are you hardware accelerating or software accelerating?
I noticed that HW accl is laggy, buy software accl is smooth
Yes, I am sure that I play my videos with hardware acceleration, and about your observation, I beg to differ. The way I understand it is like this: with hardware acceleration, the task of video playback is offloaded to the GPU, hence better rendering, frame rate and better battery performance. If you use software rendering, the whole task is given to the CPU, which will need to run at full speed to decode, and there is no guarantee that it plays smoothly. For instance, on my Sensation, without hardware acceleration, 1080p videos are impossible to play.
I am still trying every possible solution to my video playback problem. Yesterday I also tried Sebastian's latest kernel, with GPU overclocked, the frame rate is getting better, but it is still not on par with Gingerbread's performance.
Any other suggestions?
