This topic provides answers to frequently asked questions about LinkVisual Player for web.
Does LinkVisual Player for web support playing RTMP videos?
No, LinkVisual Player for web does not support playing Real-Time Messaging Protocol (RTMP) videos. To play RTMP videos on browsers, the Flash Player plug-in is required. However, the Flash Player plug-in is disabled on browsers such as Chrome. In this case, you cannot use LinkVisual Player for web to play RTMP videos on browsers.
Video streams can be downloaded from the FLV URL for live streaming but cannot be played. Why does the playback fail?
This is because browsers have high requirements for the quality of video streams. Dirty data that occur in video streams will interrupt the playback. In this case, the player will retry connections for playback. If the maximum number of reconnections is exceeded, the player stops retrying connections for playback.
Why does the playback fail a few minutes after HLS videos are played?
Check whether the cacheEncryptionKeys parameter is set to true in the code used to initialize the player.
If this parameter is not set, the player requests the encryption key each time before it obtains TS segments. After a few minutes, the token used to call an interface for playback becomes invalid. Then, the interface returns the status code 401 and the playback is stopped.
Why do I need to enable muting?
Browsers prevent videos that are not muted from being automatically played.
What can I do if video streams fail to be played in a window in multi-window live streaming?
Check whether video streams can be played in a single window.
If video streams cannot be played in a single window, check whether the playback error is caused by no videos streams ingested by the device or a stream ingest error.
If video streams can be played in a single window but cannot be played in one of the multiple windows, check whether the resources are insufficient on browsers. To check the resources, change the status of the HTTP requests to
pendingon the debugging page of your browser. We recommend that you reduce the number of windows for better playback.
What can I do if stuttering occurs in a window in multi-window live streaming?
Check whether video streams can be smoothly played in a single window.
If video streams cannot be smoothly played in a single window, check whether the network resources for running the player and ingesting video streams are sufficient.
If video streams can be smoothly played in a single window but cannot be smoothly played in one of the multiple windows, check whether the stuttering is caused by insufficient decoding or downloading capabilities of your browser. To reduce the resource consumption of your browser, we recommend that you reduce the number of windows for better playback.
