Larix Screencaster allows streaming the content of your screen via SRT/RTMP/RTSP/RIST

Larix Screencaster allows streaming your device' screen content in real-time over WiFi, EDGE, 3G, LTE and 5G.
~ Live H.264/AAC encoding.
~ HEVC(H.265) encoding (where available).
~ RTSP and RTMP streaming over TCP.
~ RTMPS and RTSPS support - SSL for RTSP and RTMP.
~ Supports SRT streaming over UDP in Caller (Push), Listener and Rendezvous modes, SRT library version 1.5.0.
~ RIST protocol streaming in Push mode: RIST Main Profile via libRIST version 0.2.7
~ HEVC over RTMP is supported as non-standard experimental feature.
~ Larix Grove support for easy links distribution via Grove links import.

~ 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.

No sound with SRT?

Picture looks good when I stream to castr But there is no sound. I can use RTMP on other apps and I have sound

Developer Response ,

Unfortunately iOS doesn't allow getting apps' audio, check Q23 in our FAQ

Cannot setup.

The apple video explaining how to set this up is private and cannot be viewed. The video showing the button to stream does not explain how to make that button appear and the button never shows up. Cannot start stream because of this.

Developer Response ,

Please check our docs reference here to learn more about launching screencasting under iOS

Doesn’t work, support videos show a different version

Apples support video has been privated. The one that the app shows has a totally different UI that allows them to start a stream. This app doesn’t have any option to start a screencast.

Developer Response ,

We'll try to update our video. Anyway, the screencasting needs to be started from iOS, not from our app.
