Decoding multiple H.264 streams with i.MX8M VPU?

martin_gisbert — Mon, 20 May 2019 11:01:05 GMT

Hi,

the i.MX8M's VPU features a 1080p60 H.264 decoder (up to high profile). Is it possible to use this VPU to decode *multiple* streams with a lower frame rate, e.g. 4 streams of 15 fps each? Or possibly even more streams with a lower resolution and/or profile, like maybe 6 x 720p15 (low profile)?

Thanks,

Martin

Yes its possible, MX8M its up to

4K @ 60fps with High Dynamic Range:
- h.265
4K @ 30fps
- h.264

Thanks for the response, but I guess my question was not clear enough, so let me get more specific:

My customer is using several IP cameras and their capture should be shown on a display. So there are 2-4 H.264 streams that have to be decoded.

Is this possible with the i.MX8M VPU?

Thanks,

Martin

Hi,

I got the same question.

2to4 IP Streams from Camera and it should be shown on monitor.

Is it possible with i.MX8M or i.MX8MQM?
