Live Play
On a Summit Client you now have the ability to play a currently recording asset in Live Mode. This means that the player will play within a 0.5 second of the record position.
Note: the Summit must have an AppCenter Pro license for this feature to work.
Note: playing live only works if the asset is currently being recorded on a channel that is on the same Summit Client as the player channel.
Check if a channel is in Live Mode:
You can check if a channel is in Live Mode by querying a ChanStatus object's "CountdownStr" property (see Get channel status properties). Normally, this property would return a timecode string representing the amount of play time left on the timeline. In Live Mode this property will return the string "Live".
string countdown = (string) ichanStatus.GetStatus("CountdownStr");
Setup a channel for Live Mode:
Full sample code can be downloaded from the C# Script Samples page. Look for the sample named LivePlay.cs.
Below is a code snippet showing how to setup Live Mode on a player.
[C#] // setup defaults string volume = "V:"; string bin = "default"; string clip = "Clip"; string clipUri = String.Format("edl/cmf//local/{0}/{1}/{2}", volume, bin, clip); // after starting a recording, you need to wait until the clip is // under construction. if you don't wait and you tell the player to // go into live mode, the player will cue to the start of the clip // instead and you will see this message in the log: // "Can't go live: not under construction. Cueing to 0." // wait until the clip is under construction... while ( true != (bool) mediaMgr.GetProperty(clipUri, "underConstruction") ) { Thread.Sleep(50); } // load the recording clip onto the player player.Load(clipUri); // Cue to the live position and start playing. in this case the command // name "cue" is a bit of a misnomer since this command does more than // just cueing here. it cues to the latest updated play position which // will be within a 0.5 second of the record position and starts playing. // // note: playing live only works if the asset is currently being recorded // on a channel that is on the same Summit as the player channel. player.Cue("live");
