USB Bandwidth

[dmorilha]

First of all, thank you for such an incredible project. I've been using motion since 2012 and it just works great.
Lately I was struggling to get more than one usb camera on a raspberry pi due to the bandwidth limitation pointed out in the documentation.
The solution was to use mjpeg-streamer (another excellent project) which doesn't suffer from the problem and open the two cameras as netcams in motion.
But I just realized the same can be achieved by setting v4l2 mjpeg palette in video_params. So perhaps the documentation could be updated with that trick.
Thank you all again!

But it is already mentioned on the page of uvcvideo: https://www.ideasonboard.org/uvc/faq/

Dude! You totally saved me a lot a time. Just setted v4l2 palette and its working. Before I used orange pi PC to just stream the cam to the pc. Thank you again sir!

not a problem and glad I could help, the issue is not trivial to figure out, and it should be made more explicit in the logs.
