i.MX6 Video Encoding/Decoding capabilities confusion

[mahi]

Hi Community,

I am a little confused about the video encoding/decoding capabilities of i.MX6.

The VPU section in the reference manuals of Quad and DualLite say that both can de- and encode H.264 up to 1080p@30fps.

But the parametric list (i.MX6Q|i.MX 6Quad Processors|Quad Core|NXP) says that Quad is able to decode 1860p@60fps.

Which one is correct?

Can someone tell me, what happens if I try to decode a 1080p@60fps H.264 video using i.MX6DL?

Is there a way to reduce framerate before decoding (or to skip every 2nd frame)?

Best regards

 Martin

Thank you very much for leading me to the right documents.

Somehow I lost track in all that documentation.

Hi Martin

please refer to sect.6.5.2 Video codec specifications attached Release Notes

for video perfomance provided in nxp linux bsps described on

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

Depending on board configuration, use case, buses loading, e.t.c., fps may be better.

For frame skipping one can refer to sect.4.3.3.2 Frame Skipping Option i.MX

VPU Programming Linux Manual.
