We would like to use it on our board with GStreamer, as the conversion done by the CPU is not very efficient :). What is the easiest/best approach to this ? Should we create a video device using a new driver, which would be instanciated as a /dev/videoX and see as a transform element in GStreamer ? The idea is to have a separate element, ideally without memory copy or anything like that. I have a similar question, regarding the scaler part. It seems to be limited by nature to 1024x1024 frames. In FSL BSP there is a split to have greater frames. Is there something doable right now with the kernel, or should we write something else ? Thanks !
