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) mode, SRT library version 1.4.3.
~ RIST protocol streaming in Push mode: RIST Main Profile via libRIST version 0.2.0
~ 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.

How to start stream

Go to settings in ur iOS mobile or iPad then control center
In there make sure screen recorder is in the shortcut.if not add to the shortcut panel by pressing plus sign.

Then drop down the shortcut panel in your device..then long press the screen recorder icon (icon looks like concentric circles)

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.

Working for iOS?

I installed and configured the app, but it doesn’t give me a start streaming option.

Developer Response ,

Please take a look at Aple docs about initiating the streaming and other docs from our reference
