Mobile Live Video Broadcasting

This document describes the live playback feature of Live Flutter Plugin.

, the video source is pushed by the host in real time. When the host stops pushing the source, the player will also stop playing the video. Because the live stream is played back in real time, no progress bar will be displayed in the player during the playback.

Common live streaming protocols are as listed below. We recommend you use an FLV-based live streaming URL that starts with 

 for LVB. For LEB, we recommend you use the WebRTC protocol. For more information, see 

https://www.tencentcloud.com/document/product/1071/41875

LVB and LEB are priced differently. For details, see

does not impose any restrictions on the sources of playback URLs

, which means you can use it to play both Tencent Cloud and non-Tencent Cloud URLs. However, the player of the SDK supports only live streaming URLs in FLV, RTMP, HLS (M3U8), and WebRTC formats and VOD URLs in MP4, HLS (M3U8), and FLV formats.

Tencent Cloud offers an easy-to-understand API example project to help you quickly learn how to use different APIs.

setRenderRotation: Clockwise rotation of video

Technically speaking, you cannot pause a live playback. In this document, pausing live playback refers to 

. While the video is frozen, new video streams continue to be sent to the cloud. When you resume playback, it resumes playing the current latest stream. This is different from pausing and resuming playback in VOD, in which the player behaves the same way as it does when you pause and resume a local video file.

The live playback feature of the SDK is not based on FFmpeg, but Tencent Cloud's proprietary playback engine, which is why the SDK offers better latency control than open-source players do. We provide three latency control modes, which can be used for live showrooms, game streaming, and hybrid scenarios.

For more information on stutter and latency control, see 

https://www.tencentcloud.com/document/product/1071/41876

. Then, all internal SDK status information, such as player status, playback volume level, reception of the first audio/video frame, statistical data, warnings, and errors, will be notified to you through corresponding callbacks.

 notification is triggered once every 2 seconds to provide real-time feedback on the current player status. It can act as a dashboard to inform you of what is happening inside the SDK so you can better understand the current network conditions and video information.

 is the callback for the player volume level. It will be returned only when you call

Other callbacks are triggered when specific events occur.
