Hi all,
I have developed an Android VR player, which supports 4K video playback so far. I want to include the support for 8K video. The current Snapdragon 845 mobile platform supports up to 4K video playback, which lacks the support for my requirement. So I choose Android-x86 as my platform for development, which is Android OS runs on Intel x86 architecture. I've tried to play 8K(7680*3840) HEVC encoded video on Android-x86 7.1-r2 with VLC for Android, the screen freeze. My CPU is Intel Core i5-7400 and my graphics card is NVIDIA GeForce GTX 1060. I am pretty sure my NVIDIA card is able to decode 8K video. Because with the same hardware, I play the same 8K video on Ubuntu 16.04 with ffplay smoothly. NVIDIA's decoder usage is about 40% and CPU usage is about 50%.
From NVIDIA website (https://developer.nvidia.com/nvidia-video-codec-sdk#NVDECFeatures), we know Pascal cards support up to 8192*8192 resolution video decoding acceleration with HEVC codec. From Nouveau feature matrix (https://nouveau.freedesktop.org/wiki/FeatureMatrix/), we know the progress of video decoding acceleration on NV130 family (https://nouveau.freedesktop.org/wiki/CodeNames/#NV130) is TODO. In Nouveau VideoAcceleration page (https://nouveau.freedesktop.org/wiki/VideoAcceleration/), we can see that each element in VP6+ row is TODO as well.
I can imagine there is a long way to go to fulfill my requirements. But I know a driver for my NVIDIA card is a must for the hardware decoder to work. Can somebody shed some lights that if I want to play an 8K HEVC encoded video on Android-x86 with NVIDIA's decoder enabled, what should I do in this project? And how to start?
Best regards,
Victor
