Grab a buffer to an unsigned char*
 
|
Hello all!I'm building an application to capture data from V4L2 cameras. It is working well, I can access my camera and see the images, etc..I'd like get the buffer that gstreamer gives me from my camera and put into an unsigner char*, RAW data, to make possible process them, apply filters, etc.
Thanks in advance! -- "I hear that if you play the NT 4.0 CD backwards, you get a satanic message" "...That's nothing. If you play it forward, it installs NT 4.0!"

But that depends on what you're trying to achieve.

Thanks!I solved using GST_BUFFER_DATA(), signal-handoffs and fakesink on my pipeline! Best regards!
