About this app

Larix Screencaster allows you streaming your presentations, games and app demos to wide audience by capturing screen of your Android device and transferring it in real-time over WiFi, EDGE, 3G or LTE to any media service or server.

Some tech specs:
~ Live H.264/AAC encoding.
~ H.265/HEVC encoding on supporting devices.
~ Supports SRT streaming protocol based on reliable UDP, library version 1.4.4.
~ Supports RTSP and RTMP TCP streaming protocols.
~ Supports SSL for RTSP and RTMP (RTSPS and RTMPS).
~ HEVC over RTMP is supported as non-standard experimental feature.
~ On Android 10, record audio from apps which support external recording. Choose Audio -> Sound settings -> Media sounds.
~ Mix microphone and media source audio
~ Select sample rate and stereo/mono for audio.
~ Saving to MP4.
~ Connects to any media server like Nimble Streamer, Wowza Streaming Engine™, Red5, Flussonic or any other capable of mentioned protocols.
~ Android version 5.0 (Lollipop / API 21) and later is supported.
~ Multiple simultaneous connections support - add several connections profiles and choose up to 3 connections for simultaneous streaming, E.g. stream to Nimble Streamer, YouTube and Twitch.

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.

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.

We test Screencaster on Xiaomi but haven't seen such behavior. Please try setting Battery saver to less strict mode for Screencaster, use Settings -> Apps -> Manage apps -> Larix Screencaster -> Battery saver and set "No restrictions"

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

The app still has the same great quality, we just had to add in-app subs to keep it sustainable.

This is what I'm looking for, very simple but very effective, thank you! If you could put an option to set fps that would be great :D
