Larix Broadcaster

Larix Broadcaster allows to encode and broadcast video and/or audio live content from your mobile device in real-time over WiFi, EDGE, 3G, LTE and 5G.

~ Live H.264/AAC encoding

~ HEVC/H.265 encoding (where available)

~ Supports RTSP and RTMP streaming over TCP.

~ Supports SSL for RTSP and RTMP (RTSPS and RTMPS)

~ Supports SRT streaming over UDP in Push (Caller) mode, SRT library version 1.4.1.

~ HEVC over RTMP is supported as non-standard experimental feature.

~ Front and back cameras are supported with hot switch.

~ Landscape and portrait mode, with "always horizontal" support.

~ Video stabilization - where it's supported by device.

~ FPS selection - dependents on device' capabilities, see below.

~ Saving to MP4, making screenshots.

~ Custom white balance, exposure value and anti-flicker.

~ VU-meter.

~ Flash light support.

~ Selfie stick support.

Notice on 60FPS support: most of mobile devices with 60 fps cameras do not provide this capability to third-party apps, so only in native camera app can do it. So if your device has that support, most probably Larix won't be able to use it.

~ 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.

~ Streams to any media server like Nimble Streamer, Wowza Streaming Engine™, Red5, Flussonic or any other capable of RTSP, RTMP and SRT input.

~ 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.

~ With 5G technology, multi-point publishing allows easily delivery to multiple points.

~ Limelight authentication support - publish your streams directly into Limelight CDN for further delivery.

~ Akamai / Dacast authentication support - publish streams to any Akamai-powered CDN like Dacast.

~ Support for Periscope Producer - choose correct Target type when creating connection

~ Long press preview to focus lens to infinity, double tap for continuous auto focus.

App keeps streaming while not in focus. This is experimental feature, in order to use it, please enable Developer options, then enable Foreground service and re-start app by double tapping Back button.

Larix Broadcaster允许通过WiFi，EDGE，3G，LTE和5G实时编码和广播来自移动设备的视频和/或音频实时内容。

〜实时H.264 / AAC编码

〜HEVC / H.265编码（如果可用）

〜支持通过TCP的RTSP和RTMP流。

〜支持用于RTSP和RTMP（RTSPS和RTMPS）的SSL

〜支持在推送（调用方）模式下通过SRT库1.4.1版通过UDP进行SRT流传输。

〜支持RTMP上的HEVC作为非标准实验功能。

〜前后摄像头均支持热开关。

〜横向和纵向模式，具有“始终水平”支持。

〜视频稳定-设备支持的位置。

〜FPS选择-取决于设备的功能，请参见下文。

〜保存到MP4，制作屏幕截图。

〜自定义白平衡，曝光值和防闪烁。

〜VU计。

〜闪光灯的支持。

〜自拍杆的支持。

关于60FPS支持的注意事项：大多数具有60 fps相机的移动设备不向第三方应用程序提供此功能，因此只有在本机相机应用程序中才能实现。因此，如果您的设备具有该支持，则很可能Larix无法使用它。

〜ABR（自适应比特率）在2种模式下可用：

-对数下降-从最大比特率逐步下降。尝试每分钟返回到上一步。最适合良好的网络。

-阶梯上升-首先将比特率降低2/3，然后将其尽可能多地恢复正常。尝试在15秒，1.5和5分钟后返回上一步。最适合损失巨大的网络。

-可变FPS可以用作选项，除了更改比特率值外，还可以通过降低FPS来降低比特率。请注意，它在很大程度上取决于设备的功能，并且可能无法在某些硬件上运行。

默认情况下禁用此功能。在“视频”菜单中已启用。

〜流式传输到任何媒体服务器，例如Nimble Streamer，W​​owza Streaming Engine™，Red5，Flussonic或任何其他具有RTSP，RTMP和SRT输入功能的服务器。

〜支持多个同时连接-添加多个连接配置文件并最多选择3个连接用于同时流式传输，例如流到Nimble Streamer，YouTube和Twitch。

〜使用5G技术，多点发布可轻松传递到多个点。

〜Limelight身份验证支持-将流直接发布到Limelight CDN中以进一步传送。

〜Akamai / Dacast身份验证支持-将流发布到任何由Akamai支持的CDN（例如Dacast）。

〜支持Periscope Producer-创建连接时选择正确的目标类型

〜长按预览可将镜头聚焦到无限远，双击可连续自动聚焦。

应用程序始终保持流式传输，而不会成为焦点。这是实验性功能，要使用该功能，请启用“开发人员”选项，然后启用“前台”服务并通过双击“后退”按钮重新启动应用程序。
