* their MPEG streams (MIME: application/x-sgimb). Very few applications
* understand this format and the format is not really documented on the net.
* Following a typical MediaBase file. Notice the sgi prefix of all the elements.
- * This stems from the fact that the MediaBase server were first introduced by SGI?????.
+ * This stems from the fact that the MediaBase servers were first introduced by SGI?????.
*
* sgiNameServerHost=host.name.tld
+ * Obvious: the host hosting this stream
* Stream="xdma://host.name.tld/demo/a_very_cool.mpg"
+ * Not always present. xdma can be read as RTSP.
* sgiMovieName=/demo/a_very_cool.mpg
- * sgiAuxState=1
+ * The path to the asset
+ * sgiAuxState=1|2
+ * AuxState=2 is always Video On Demand (so not Scheduled)
+ * Not present with Live streams
+ * sgiLiveFeed=True|False
+ * Denounces if the stream is live or from assets (Canned?)
+ * Live appears as a little sattelite dish in the web interface of Kasenna
* sgiFormatName=PARTNER_41_MPEG-4
+ * The type of stream. One of:
+ * PARTNER_41_MPEG-4 (RTSP MPEG-4 fully compliant)
+ * MPEG1-Audio (MP3 Audio streams in MPEG TS)
+ * MPEG-1 (MPEG 1 A/V in MPEG TS)
+ * MPEG-2 (MPEG 2 A/V in MPEG TS)
+ * sgiWidth=720
+ * The width of the to be received stream. Only present if stream is not Live.
+ * sgiHeight=576
+ * The height of the to be received stream. Only present if stream is not Live.
* sgiBitrate=1630208
+ * The bitrate of the to be received stream. Only present if stream is not Live.
* sgiDuration=378345000
+ * The duration of the to be received stream. Only present if stream is not Live.
* sgiQTFileBegin
* rtsptext
* rtsp://host.name.tld/demo/a_very_cool.mpg
* sgiQTFileEnd
+ * Sometimes present. QT will recognize this as a RTSP reference file, if present.
* sgiApplicationName=MediaBaseURL
+ * Beats me !! :)
* sgiElapsedTime=0
+ * Time passed since the asset was started (resets for repeating non live assets?)
+ * sgiMulticastAddress=233.81.233.15
+ * The multicast IP used for the Multicast feed.
+ * Also defines if a stream is multicast or not. (blue dot in kasenna web interface)
+ * sgiMulticastPort=1234
+ * The multicast port for the same Multicast feed.
+ * sgiPacketSize=16384
+ * The packetsize of the UDP frames that Kasenna sends. They should have used a default
+ * that is a multiple of 188 (TS frame size). Most networks don't support more than 1500 anyways.
+ * Also, when you loose a frame of this size, imagecorruption is more likely then with smaller
+ * frames.
* sgiServerVersion=6.1.2
+ * Version of the server
* sgiRtspPort=554
+ * TCP port used for RTSP communication
* AutoStart=True
+ * Start playing automatically
+ * DeliveryService=cds
+ * Simulcasted (scheduled unicast) content. (Green dot in Kasenna web interface)
+ * sgiShowingName=A nice name that everyone likes
+ * A human readible descriptive title for this stream.
+ * sgiSid=2311
+ * Looks like this is the ID of the scheduled asset?
* sgiUserAccount=pid=1724&time=1078527309&displayText=You%20are%20logged%20as%20guest&
+ * User Authentication. Above is a default guest entry. Not required for RTSP communication.
* sgiUserPassword=
+ * Password :)
