Hi manizillion@gmail.com,
The SW ISP is an independent software. 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 are no plans to use SW ISP with GStreamer. However, I noticed that RidgeRun did a great work by creating this solution as a GStreamer plugin, the GstISP, and it supports i.MX 8: GStreamer Based Image Signal Processor - IMX8 Pipelines
Please, let me know if it helps.
Best Regards,
Marco
