Steps to reproduce:
1.Manually start/stop CA without vga signal.
2. After plugging back in signal, I try to start another capture and it just hangs. But it appears that sometimes it works again. My theory is that the pipeline takes too long to shut down, and while this is happening it prevents other recordings from starting. Once it shuts down it seems all is good.
