Detect changes in resolution in a mjpeg stream

[Guillermo Rodriguez Garcia]

Hello all,

I have a mjpeg stream that can sometimes switch to a different image
resolution on the fly. This depends on external events over which I
have no control. When this happens, I need to do some extra processing
in my application.

The pipeline is souphttpsrc ! multipartdemux ! jpegdec ! <custom sink element>

Are there any events related to multipartdemux or jpegdec that I could
use to detect these changes in resolution ?

Thank you,
