Start offsets and durations

Start offsets can be applied using either the clip or playlist configs. This will allow the player to start playlist of the video at a certain time.

clip: {
    start: 100,
    sources: [
        {type: "youtube", src: ""}
playlist: [
    start: 100,
        {type: "video/youtube", src: ""}

Flowplayer 7 has no api for playback durations therefore it can be scripted using events

player.on("progress", function () {

    if ( > 20) {

Live Events

Simply configuring the player as live will determine that it is a live stream with no duration. If the stream is configured to publish as DVR, setting the player config to dvr will enable dvr playback and to play at the current live time. For mobile browsers this will be set as live.

    live: true,

    dvr: true,
