Hello!, we are doing some tests with xwalk to see if we can replace our current phonegap based application. For us the most important feature is being able to play videos at full HD (1080). This is something that our target android devices are capable of doing without any problems as it can be demonstrated by using the built in media player. The hardware is a dual core cortex A9 1.6Ghz, with a Quad-core Mali 400 GPU. Android 4.2.2.
You can read more about it here: http://www.minix.com.hk/Products/MINIX-NEO-X5mini.html Now, when using xwalk we have two issues. The first one is that the video playback takes between 2 to 5 seconds to start (while starting a video with builtin media player is instantaneous), the other is that the video playback is not very smooth, largest problem is that from time to time some "hack" appears which makes it very noticeable. I tried using latest version of Chrome (version 39), video decoding is even worse here, very jerkey. In the chrome:\\flags it says that it is using hardware video decoding but not hardware rasterization (gpu_rasterization disabled), seems like the GPU in this device is not fully supported. However we can force it to use the GPU in chrome:\\flags, and after that the video playing is much better. So my questions are: 1) Is GPU rasterization enabled by default in xwalk, or is it disabled as in Chrome?, if so, can it be forced, and is it a good idea to do it?. 2) What other tips can you give me to improve the video playing performance?
