Controlling your video streams

After you select a video stream(s) for display, a media player bar opens along the bottom of the display frame. The media player bar controls all of the video stream(s) in your window simultaneously.

The player buttons allow you to rapidly scan through historical programs. From left to right, the buttons perform the following functions:

  • 1F: Frame rewind; rewinds one frame each time the button is pressed

  • X1/2 half-speed rewind: Rewinds at half the normal frame rate

  • Fast rewind: Rewinds at twice the normal frame rate, or continue to click for 8x

  • Rewind: Rewinds at the normal frame rate

  • Pause: Pauses playback

  • Play: Moves forward at the normal frame rate

  • Fast forward: Moves forward at 2x the normal frame rate, continue to click for 8x

  • X1/2: Half-speed forward playback

  • 1 Frame forward: Advances one frame each time button is pressed

  • LIVE: Synchs up all the video streams in the player window with the most recent content; two ways to ensure you are viewing the most recent content:

    1. The LIVE indicator on player turns green when playing a live feed and white when playing a historical program

    2. Most recent view by the date/time identification at the top of the player

The power of Volicon Media Intelligence service is in its ability to support many sessions or users simultaneously without affecting other users. For example, what you do in the “Player” window only affects your “Player” window. It has no effect on other users. Volicon Media Intelligence service is the only program of its kind that provides you with the complete freedom to perform your job functions when and as you need to perform them.

In the example below, both video streams are paused. Clicking on the <LIVE> button causes the Volicon Media Intelligence service to simultaneously retrieve the current live content for both streams.

Use the volume control, located in the lower right-hand corner of the page, to set or mute audio. If you have multiple video streams open, you only hear audio from a single stream. Left clicking inside any open video stream enables audio for that stream and mutes the others. The channel name turns blue to indicate the active audio channel.

Seeking within a program

The Volicon Media Intelligence service media player video feeds do not have a finite end to the video stream like other internet-based video streams. Therefore, we cannot count down to the end of the currently playing video. Instead, the seek bar is used to select a time duration. Once selected, the value is displayed in the seek bar as a reminder.

Clicking anywhere on the <Seek> bar resets the program to a new time relative to the duration of the bar. If the program has been recorded, you can easily seek forward or backward in time. When the program reaches the end of the seek bar duration, the bar is automatically reset to the next interval, either forward or backward in time.

Click on the <Seek time> image button at the lower right-hand corner to change the duration of the seek bar.

Time info is displayed at the top of the player. To return to the most recent content, click the <LIVE> button, and all video streams will begin playing live content again. Each open window may be individually controlled in the same manner by clicking on the <LIVE> icon within the individual video player.

Live program time accuracy

In this context, “live” means “real time to Volicon Media Intelligence service.” Volicon Media Intelligence service ingests live video, transcodes it, stores it and streams it out to you as an end user. This process takes a few seconds. Thus, the “live” feed is several seconds behind real time.

Due to the amount of time it takes Volicon Media Intelligence service to ingest the video stream, and the accuracy (or lack thereof) of your PC real-time clock, the time displayed on the live video stream may lead or lag the time on your computer by several seconds. The size of the difference is a combination of the time it takes Volicon Media Intelligence service to ingest the video stream and how accurate and often your PC is synchronized to an NTP server.
