i.MX8 Software ISP utilization

jbirchy — Mon, 20 Apr 2020 19:54:33 GMT

I’m trying to understand, how the SW ISP (https://www.nxp.com/design/designs/i-mx8-software-image-signal-processing:SOFTISP-I.MX8 ) is utilized with a streaming camera input & the VPU.

I would like to know how to acquire a 1920x1080 camera stream via MIPI_CSI, run it through the SW ISP, then through the H.264 encoder, and finally output it onto the ethernet port. Basically creating an IP camera.

I am told that the SW ISP runs in OpenCV and can achieve 39 fps @ 1920x1080 with an i.MX8MQ, is that correct? We are actually hoping for 1080p60.

Hello John

Correct! you can get 1080p60hz with 30fps with ISP.

So how is the SW ISP utilized on a camera input stream which includes a H.364 encode following the SW ISP function?

Hi Birchy‌,

The SW ISP is a stand-alone prove of concept. It cannot be used in combination with GStreamer.

For more details on it, please, check the SW ISP release page: https://www.nxp.com/design/designs/i-mx8-software-image-signal-processing:SOFTISP-I.MX8

Plus, I confirmed with the Multimedia team, and there is no plans to use SW ISP with GStreamer. However, I noticed that RidgeRun did a great work by creating this solution as GStreamer plugin, the GstISP, and it supports i.MX 8: GStreamer Based Image Signal Processor - IMX8 Pipelines

I hope it helps.

Best Regards,

Marco
