I`m doing some test using encodedecode Demo, and I can`t fine where the sourcecode for functions in Capture,h file like capture_get()..

The Capture_get() function is a DMAI (Davinci Multimedia Application Interface) function, so you can find the sources in the DMAI install that is being used when you rebuild the encodedecode demo. Which specific source file contains the function depends on your DVSDK version and device, in this case as an example you may find the Capture_get() function source you seek at a location like dvsdk_2_00_00_22/dmai/packages/ti/sdo/dmai/linux/dm6446/Capture.c.
