Part Number: TDA4VM
We have a 4-virtal-channels camera stream feed into CSIRX0 port, the camera streams come from a deserizer; when configed to capture any one of the steams, it works well, but when we try top capture all four streams, we encounter accumulate "drop frames" or even blocked pipeline (when pipeline stop, we press 'p' to show statistics and the stream may recover to run).
The virtual channels are not synchronized, does that affect the capturing of the images? all VC are of the same resultion and frame rate.

My question, why are there dropped frames? how to avoid it?
