TDA4VH camera question

yes, it can be supported via virtual channels in one CSI instance. thanks. 

is there any demo? in 0805 sdk the camera driver only can set one resolution,how to set multi resolution on 0900,can you show some example?

and what is the modify from 0805 to 0900?

I compare RTOS 0805 sdk with 0900 sdk,it seems no change about camera driver and image ovx,plz show how can one driver set two diff resolution to one CSI instance? 

I do not see virtual channel design in RTOS camera driver,please confirm it

Hi xu ji,

sorry did not get your question, what do you mean by virtual channel design? virtual channels are always supported in the CSIRX. We have multi-camera demo in vision apps, which captures images from multiple camera using virtual channels. Is this what you are looking for ?

Hello， Brijesh

The question about this case e2e.ti.com/.../question-about-capture-node-on-tda4 before,
also ask: if I create capture node that csi instance is 0 and all four channels must be same resolution? the other capture node is csi instance 1 it's resolution can be diff with capture node that csi instance is 0?

you answer one csi instance can not support multi resolution, now SDK0900 release I want know this support or not support also?

Thanks

Hi xu ji,

When we create one instance of CSIRX0, all channels within this instance must have same properties. But you can create second instance of CSIRX0 and this second instance can have different properties for the camera from the first instance.

This should work, i think there is an example for it in ti-processor-sdk-rtos-j721e-evm-08_06_00_12\tiovx\kernels_j7\hwa\test\test_csitx_csirx.c file. can you please refer to it?

this is mean create two CSIRX node in one graph，one node is get resouce CSIRX0 with channel0 is camera 0,another is resouce CSIRX0 with channel1 is camera 1,is it right?

but in camera sensor driver IssSensor_CreateParams there is only one width and height setting then need the graph call two camera driver, one driver is for camera 0 another is for camera 1? and then single camera driver or multi camera driver need adapt to camera 0 and camera 1,the single camera driver only can set CSIRX channel0 now, and two camera driver will both set deserializer will conflict.

If this I said above, can iss_sensors struct support it?any example?

Hi,

Well i was talking about the capture node perspective. There might be changes required in the sensor layer.. In the sensor layer, you can also probably create two instances and the manager them.

so that, with 0900 SDK release sensor driver layer also can not support this scene，right？and in TI side also not 

for more, is there any plan to support the scene in the future? 0903 or 0905 maybe
