TDA4VM: Can multiple capture graphs run at the same time

shiqiang zheng

Part Number: TDA4VM

Device: TDA4

SDK Vesion: sdk7_03

TDA4 has two CSIRXs, CSIRX0 and CSIRX1. We want to put CSIRX0 and CSIRX1 into two independent graphs, and these two graphs work at the same time. Please help evaluate whether this is feasible?
There are two usages:
case1: CSIRX0 connects to a RAW camera, and CSIRX1 connects to another RAW camera. Can the CAPTURE, VISS, NF, LDC, MSC modules be put into two independent Graphs, and these two Graphs work at the same time
case2: CSIRX0 connects to RAW camera, CSIRX1 connects to YUV camera, YUV camera does not require VISS and NF modules. In this case, can CSIRX0 and CSIRX1 be put into two independent graphs, and these two graphs work at the same time

Hi zheng,

Yes, as such, it is possible to use both CSIRX instances in two different graphs.

But case1 requires changes in the VISS, which is not currently supported.

case2 can be definitely supported.

Hi Brijesh,

Case1 needs to change VISS, whether to change the hardware or software? and which date will it be supported?

Hi zheng,

case1 requires change in the driver. Essentially, it requires to restore context on almost every frame, because every frame could be from different camera.. This is currently not supported.

This should be available in 8.x release.
