How to get GstVideoInfo from GstBuffer

Wed Nov 16 12:23:08 UTC 2016

Hi,

I'm adding GstPadProbe to the sink pad of textoverlay element to know its
video resolution with the probe_type as GST_PAD_PROBE_TYPE_BUFFER

I'm getting GstBuffer *buffer in the callback. How can I extract
GstVideoInfo fro GstBuffer?

Thanks

~BO
