OTG USB cameras are supported for MJPEG and YUYV formats. Use Advanced options to enable "USB Camera".
Notice that some cameras may not work on some mobile devices due to hardware and software limitations.

60FPS support: most of mobile devices with 60 fps cameras do not provide this capability to third-party apps, so only in native camera app can do it. So if your device has that support, most probably Larix won't be able to use it.

~ ABR (adaptive bitrate) is available in 2 modes:
- Logarithmic descend - gracefully descend from max bitrate down step by step. Retries to raise back to previous step every minute. Best fit for good networks.
- Ladder ascend - first cut bitrate by 2/3 and increase it back to normal as much as possible. Retries to raise back to previous steps in 15 seconds, 1.5 and then 5 minutes. Best fit for networks with big losses.
- Variable FPS can be used as an option, it will reduce bitrate by decreasing FPS in addition to changing the bitrate value. Notice that it heavily depends on your device' capabilities and may not work on some hardware.
This feature is disabled by default. It's enabled in Video menu.

~ Streams to any media server like Nimble Streamer, Wowza Streaming Engine, Red5, Flussonic or any other.
