I have a board with a adv7482 and I get video from it with v4l2src.
When something happen on adv7482 HDMI input (a disconnection for instance),
the adv7482 goes to free run mode with a blue screen with the same video
configuration that was before.
But the gstreamer pipeline crash's with v4l2src error "Could not read from
I think in this kind of transition there some frames lost or invalid.
Is there any way to avoid it? Maybe a buffer on v4l2src?
