Or you can add subtitles on the page and get a code that can be inserted into your site. Specify the name for the language (for example, “EN” or “english”) and the link to the VTT subtitle file.

Does the player support auto select quality?

If your video has several qualities (in HLS and DASH formats), by default, when you start the video, the optimal quality will be selected, based on the speed of the Internet connection (bandwidth). Different browsers handle auto-select differently. Most choose the best possible, but optimal in terms of bandwidth (most often 720p). But some browsers (Mozilla FireFox, Opera versions less 80, Chrome versions less 85 on tablets, and some others) prefer low quality by default.

Auto selection of maximum quality

If you have a need to always automatically display the maximum quality in all browsers without exception, use the setting “Init Max Quality” on constructor page. In player code will be added &initMaxQuality=true, which “tell” your browser to choose the maximum possible quality automatically.

Does the player support multiple audio tracks?

Yes, our player supports the selection of audio tracks in the interface. Audio tracks should be added into mp4 before the file is converted to HLS or DASH playlist. The HLS format supports custom audio track names (you can set them through our constructor). The DASH format will display the track name as it was originally set in the mp4 file itself. The mp4 format supports up to 16 embedded audio tracks.

Support player functions for users with disabilities

The Playernow can be operated by users with disabilities. Using the TAB key on the keyboard, you can navigate through the player's buttons, calling up the submenus and confirming your choice of settings with the Enter key.
