When streaming to YouTube, please enable the sound because YouTube doesn't like streams with no audio.

~ 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.

Ratings and reviews

Experience bug. Foreground service for screencaster will closed at miui even it is locked. I'll revert back to previous version - locked mean the apk marked for not closed. Not screen locked. I bet you guys never tested at miui OS. Try it, other screen capture once it marked lock, then clear running app still running because marked as locked. But larix, well, foreground service shutdown with a result ended broadcast.

I was happily using the app without any issues, for local RTMP streaming, until addition of "Premium" which made it an completely unusable garbage.

love your app larix...simple to use... please make more simple setting for URL setting for youtube ,I have read all the tutorials in your website for URL settings and finally youtube streaming is possible.. 5 stars from my side
