TMDSEVM572X: How to use DSP in front of GStreamer

(Gstreamer1.0 v1.8/ Linux 4.4)

Hi,

I want to do an application who apply video transformation on a couple of video and audio input with the capability of DSP before doing a streaming of selected audio/video (only one).

I want to now if there is a doc. or software example for my issue :

How to use C66x DSP features to capture (for example) two videos FROM Video Inputs Ports VIP1 VIP2 and two audio FROM AudioIn Left=Audio1 Right=Audio2

And then in the "IVA(?) Video Acceleration" : How to select the video source in Gstreamer from the DSP video output to use it in a pipeline ?

Thank You

Are you using PSDK Linux or RTOS? On PLSDK (PSDK Linux) VIP driver is linux based running on A15 and hence capture can only happen on A15 side. You can use v4l2src gst plugin to capture using VIP. I am not sure though if that gstreamer plugin supports capture from multiple camera source.

Once captured on A15 side, the frame can be passed to DSP for further processing. Check below wiki links -

What's your exact use case?
