Hi Andrea, Thanks for reply.
1) DVSDK 1.30 kernel does not provide CONFIG_CAPTURE_DAVINCIHD ( I could not find in autoconfig.h or KConfig anywhere, but Makefile mentions about it). Do I have to apply patch to enable support this? (I tried tweak it manually but looks like I have to disable part of VPFE!!) 2) I am not getting any error after hardcoding buffer size to 884736, and able to dequeue and enque buffer successfully, but this buffer does not contain any frame data.
