Updates to video loop & darwin support

- Corrected some Mac/Darwin support, incorrect 10 bit options (In future will remove videotoolbox support and split into separate plugin)
- Improved video check loops, some logic did seem to not correctly stop when needed & the remove stream option had the wrong syntax so probably wouldn't have worked
