Streaming Options
Specifies how an incoming live stream can be played by indicating if the
?DVR
query
parameter must be appended to playback URLs.
To specify that a live stream can be played with or without DVR playback controls,
select
Live and DVR streaming
. This option means that the live stream is available for
playback with or without the
?DVR
query parameter appended to playback URLs. If
?DVR
isn't appended to the playback URL, the live stream can still be played but DVR
playback isn't supported.
To specify that a live stream can be played only by using the DVR playback controls in
a player, select
DVR streaming only
. This option means that the
?DVR
query
parameter must be appended to playback URLs.
Recording Options
Select
Start recording on startup
to automatically begin recording a live stream that's
published to the application for DVR when the application starts.
Archive Method
These options specify how nDVR handles recording a new stream that's published to
the application with the same stream name. This often happens if the current live
stream is disrupted when encoders restart.
The
Append
option is the best option to use to handle disruptions in the live stream.
Each time a new stream with the same name is recorded, nDVR appends to the
existing recording. This is the default setting.
The
Delete
option deletes the previous recording and starts a new recording.
The
Version
option starts a new recording in a new folder in the DVR store for each
new stream. If the stream name is
myStream
, the first recording is written to
[install-
dir]/dvr/[application-name]/myStream.0
, the second recording is written to a
directory named
myStream.1
, and so on. Whenever there's a recording of the same
stream name, the previous recording is preserved and isn't deleted or overwritten.
