I notice four encoders ( H264, H265, VP8, VP9 ) all claims to support SliceIntraRefreshEnable and SliceIntraRefreshInterval.
But there is very little info on Internet how to use them. As I understand it will smooth the throughput of output packet flow, make every frame partial I/P containing I slice and P slice.
I tried to enable omxh265enc SliceIntraRefreshEnable=true SliceIntraRefreshInterval=30, but I found the output frame size is still very similar to w/o them. We can still observer perdiodic I frame about 60K bytes and 7K-10K for P frames.
Besides, I read from some article, that VP9 doesn’t support slice, so why does jetson tx2 claim the the encoder support it?
