[TX1] 4k60 video EGLImage readback stuttering

hfrappier · February 2, 2018, 6:43pm

There appears to be a performance bottleneck when hardware decoding a 4k60 video to an EGLImage target.

This happens in our application, which uses the Multimedia API, but can easily be reproduced with nvgstplayer-1.0, which uses OMX:

nvgstplayer-1.0 BBBUHD.mp4

outputs the following:

Hi hfrappier,
Please try max performance:

sudo ./jetson_clocks.sh

If the issue is still present in max performance, please share a sample based on Multimedpa API so that we can reproduce the issue. Are you on r28.1?

kayccc · February 14, 2018, 2:22am

Hi hfrappier,

Any update? Have you clarified the cause and resolved the problem?

Thanks
