Hi,

The -O option was more for debug purpose, I will probably remove it.

Hi, @mpromonet, I was able to use it, it is very usefull if you want to stream with minimum delay and get frames for another program on device, additional reencoding from one virtual camera to another using ffmpeg helped me.

Hi,

Using v4l2loopback as a source, allow you to connect multiple consumer.

Best Regards, Michel.

@mpromonet Yeah, but in my case using v4l2loopback as a source for rtspserver multiplied the delay, hope you will left -O option)
