问题
I am running "customvideoplayer" sample application present inside roku SDK on a Roku-4 device.
I got the roku SDK from this link: http://wwwimg.roku.com/static/sdk/RokuSDK.zip
I am testing a 1080p@60fps HEVC stream. The Roku-4 is connected to a 1080p@60fps TV. The issue is that the playback is not smooth. I can see some frames are rendered for more time compare to others.
My questions are:
1) According to Roku documentation(Link: https://sdkdocs.roku.com/display/sdkdoc/Video+Encoding+Guidelines), Roku-4 supports upto 3840x2160 and upto 60fps for HEVC. Does it mean it supports 3840x2160 @ 60fps?
2) I am not observing any issue with 1080p@30fps stream. So, In the sample application, do I need to set any fields or enable any flags additionally to play 60fps content?
