I want to decode 4800*3840 resolution hevc stream on skylake via vaapi, but there is no right data in the out buffer. It just display green on my screen. However, the stream that bellow 4k*4k resolution can be decoded and displayed correctly.
The version I used in my usecase are follows:
I success to decode the stream by ffmpeg on [cpu] and the [intel-gfx-prm-skl-vol10-hev] reference says that the skylake can support up to 8K*8K HEVC stream.
So I do not know if the vaapi i used is something uncorrect to decode the stream.
Thank for your response.
