Larix streaming library

Mobile streaming library provides transmission from mobile.

The content is encoded in H.264 (AVC) and H.265 (HEVC) video with AAC audio.
Streams can be delivered via RTMP/RTMPS, SRT and RTSP/RTSPS. Also, HEVC over RTMP transmission is supported as a non-standard experimental feature.
Multiple simultaneous connections allow streaming to several destinations at the same time.
You can stream to services like Facebook Live, YouTube Live, Twitch, Wowza Streaming Cloud, Akamai, Dacast as well as media servers like Wowza, Nimble Streamer, Red5 and others. Check docs reference for more examples.

Adaptive video bitrate (ABR) is supported in 3 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.
