Fixed in 0.3.18:

#48087 - fixes crashing when errors occur on the video pipeline

Worked-around in 0.3.18:

#49168 - we retry when we get v4l2src errors
#49224 - we retry when we get xvimagesink errors

Broken still:

#46368 - although 0.3.18 will handle the agreed GST_FLOW_ERROR, hantro still seems to be asserting instead
