Hello Li,

How are you measurement

The VPU of the i.MX6 can decode two streams of 1080p@30 for MPEG4 / H.264.

  The VPU of the i.MX6 can encode single stream of 1080p@30 for MPEG4 / H.264.

 

  The VPU of the i.MX6 can decode four streams of 720p@30 for MPEG4 / H.264.

  The VPU of the i.MX6 can encode three streams of 720p@30 for MPEG4 / H.264.

 

We cannot guarantee that UVC can decode at 30fps.

Regards
