Access to DVR recordings
You can view recordings by using the administration web interface. Also, you can access recordings by special URLs.
To access a recording by URLs, use stream mode or file mode.
A file, compared to a stream, has an end. That is, when playing a file, a player shows a timeline, and the video is limited (it has the beginning and the end). When playing a stream, a player doesn't show progress on the timeline, because the end of a stream is not known.
You can see this difference in URLs too. For example, a file's URL ends with "index-1345345345354-3600.m3u8" (the limits are defined: beginning at 1345345345354 and end after 3600 seconds), and a stream URL ends with "timeshift_abs-1345345345354.ts" (only the beginning is defined).
The URLs depend on the protocol that you use for accessing the DVR. Learn more in Accessing DVR by different protocols.
Electronic Program Guide (EPG)
DVR can be used with EPG. The modern approach to the provision of television archive – record the entire video, and then provide access to the archive (or rewind current video) using the EPG.
Learn more in Middleware in IPTV OTT.
All metadata will be stored in a middleware and Flussonic Media Server will provide access to this archive as an infinite tape (with convenient navigation).
Two modes exist:
- view already recorded video
- view live streams
If the show is already over, the middleware forms the link based on EPG to view the archive. The user can see the recorded movie as a normal file. For example, if the show is started at 18:15 Moscow time (14:15 UTC) on August 27 and continued for an hour, the middleware should create URL like this:
If the show is not over, the middleware may create special URL to the archive, that allows to rewind live to its beginning.
Unfortunately this feature supported on a few devices and STBs, but nevertheless it exists.
URL for this unfinished video will be like this:
Viewing DVR from the administration web interface
You can view the contents of an archive in the Flussonic Media Server UI. Click a stream name in Streams on the Media tab, then click the DVR tab. You'll see the timeline bar and video will be played in real time.
The timeline bar consists of several zones indicated with different colors. The red color means no recording at this time, green means that a video record exists, and blue means the current hour.
You can click anywhere on the timeline bar to begin playing the video starting from that time. Also you can use buttons to browse the video:
- "-" and "+" for “zooming” a time period, so you can select a time more precisely
- "<" and ">" for moving a time period to an earlier or later time than displayed on the screen.
You can select a part of an archive to export a video file in MP4 format. Just move gray limiters on the left and right. You'll see the time of the beginning and end of the selected interval next to the MP4 button. Save the file by clicking MP4.
