Hi,

 

Is it possible to view and encode a single video stream from the CSI using the IC for different tasks (IC task time sharing)?

 

For viewing the IC is required for resizing PAL or NTSC to XGA resolution. For encoding the IC is required to convert the colour space from 4:2:2 to 4:2:0 YUV.

 

In section 45.4.5.2 it states that the IC can switch between tasks but it reads like the current frame is processed using one set of parameters, the parameters are changed, and the next frame is processed using the new parameters. This suggests that two input streams to the IC are required, otherwise the display would get every second frame and the VPU every other frame?

 

If it is possible to have one input and two output flows from the IC, is there an example of how to do this in Linux?

 

Regards,

 

Leon
