support libcamera

[pdp7]

It is ideal if the JH7100 video and camera input (CSI + ISP) are able to be supported by libcamera https://libcamera.org/ @kbingham can assist with but coordination with StarFive engineers is needed in order to do do

we will try to build this rpm package to work with the latest JH7100 video and camera driver(V4L2).

[kbingham]

Is support for this platform still ongoing?

Yes, we will release V4L2 this week and the next stage is to do libcamera

[kbingham]

Does the V4L2 driver expose a CSI2 receiver as a V4L2 device, and V4L2 subdevices for the sensor? And the ISP as a separate node?

Yes, we expose sensor, CSI, DVP, ISP as v4l2 subdevice respectively.

Great, let me know if there's anything I can do to help then! Sounds like it might be time to dust off the Beagle-V-CE (collectors edition)

[MichaelZhuxx]

@kbingham thanks, definitely need your help to review code at least😄

[kbingham]

Sure, please ping me, send me the patches or notify me when they're available.

[kbingham]

What's the status on the V4L2 drivers for this ?

[MichaelZhuxx]

@kbingham Here is pre-release multimedia subsystem for JH7100, including ALSA, V4L2, Gstreamer, VPU decoding. please refer to freelight-u-sdk and readme to fetch, build and test it.

next step we will merge multimedia function to linux 5.14.y and keep it up to date

@kbingham There is some new multimedia code in the beaglev-5.13.y_multimedia branch. I think testing would be greatly appreciated.
