Request: Process video stream from stdin about dvr-scan HOT 2 OPEN

I'm not sure if using stdin works with OpenCV, but this should be possible using PyAV, so is theoretically possible. However, I do think OpenCV supports gstreamer inputs.

That being said, modern versions of OpenCV should work with RSTP streams. I think the only thing preventing this right now might be how the CLI opens videos:
https://github.com/Breakthrough/DVR-Scan/blob/master/dvr_scan/video_joiner.py#L131

It should definitely be possible to do something like:

dvr-scan -i rstp://localhost:8554/my-camera

However, using -m ffmpeg will not work, as ffmpeg is invoked a subprocess. This would only be supported using the opencv video output method. Ideally PyAV could solve that as well however, but that's something the project might need a few extra hands on to tackle.

Thanks for posting this, I'll see if this can be pulled into the next release.

This is great, thanks @Breakthrough ! If dvr-scan had the ability to take a network stream such as rtsp:// as direct input, I think that would be sufficient, and reading from stdin would be less important.
