4.4 Streaming conguration
You can set up several things for an audio-video stream. Which options are displayed, depends on the
chosen streaming mode and possible choises for that streaming mode. You will nd an overview of the
dierent options with a short explanation:
Irrelevant options are automatically omitted in the webinterface of the Maven. There-
fore, always ll in all elds, unless you are very sure you can leave the eld empty.
Field Settings
Codec You can select the audio and video codec here.
Audio quality You can set the bitrate of the audio part of the stream here. The higher
the bitrate, the better the quality, but also more bandwith that is used.
Video bitrate You can set the bitrate of the video part of the stream here. The higher
the bitrate, the better the quality, but also more bandwith that is used.
Video resolution You can set the number of pixels here (horizontal x vertical) that has to
be transmitted. The more pixels, the more detail.
Video compression You can set the compression level of the video signal here (only for H264).
A higher value for the compression level gives a better image, but also
requires more computation power. This increases the chance that er-
rors occur with complex image changes. In general lower settings result
in better results at high resolutions. The higher levels can be used in
combination with lower resolutions.
Enable de-interlace De-interlacing results in most cases in a higher quality stream, it is rec-
ommended to keep this on. In case of a striped image you can try to turn
de-interlacing o and see if it gets better.
Transport protocol You can set the transport protocol for the stream here. The options are
RTP, UDP (is always an MPEG transport stream), RTMP, HTTP and
MPEG-TS (is always RTP)
Stream destination URL or IP address of the reciever of the stream. This is provided by your
streaming service provider.
Mount point The name of your account. This is provided by your streaming service
provider. (External stream server and Streamit AVDP)
Port Port on the AVDP to which the audio is sent. The video port is Port+2.
This is provided by your streaming service provider. (With Streamit
AVDP only)
Server You can set the server here to which the stream must be sent (only for
RTMP). This is provided by your streaming service provider.
Stream You can set the stream name here (only for RTMP and HLS). For RTMP
this is provided by your streaming service provider.
Audio port Port on the reciever of the stream to which the audio is sent.
Video port Port on the reciever of the stream to which the video is sent.
Upstream port Port to which the MPEG transport stream is sent.
Local port Port on which the stream is accessible on the Maven. Do not choose a
port under 1024 or port 8080.
Segment length The number of seconds of audio/video each segment should contain (Only
for HLS). Apple recommends 10.
Number of segments The number of segments that are kept in the index le (Only for HLS).
This must be at least 3.
SDP le Here you can indicate if and how the stream description le (SDP le)
must be made available. The options are `Not required' (no SDP le is
created), `Upload to server' (the SDP le is sent to the server, see `SDP
destination URL'), and `Served by Maven' (the SDP le is available from
the Maven, this part of the URL on the status page of the Maven, see 6)
