Cycling '74 Jitter Jitter Networking Jitter QuickTime in TEXT_HERE TEXT_HERE out TEXT_HERE dumpout TEXT_HERE char Pause a running broadcast server Pauses a running broadcast server. No effect if the server is idle. Start the broadcast server Starts the broadcast server. Stop the broadcast server Stops the broadcast server. Write a session description protocol file to disk Writes an SDP (session description protocol) file to disk. This file describes the streaming parameters in a form suitable for distribution to clients. Every time a broadcast parameter is modified (vcodec, for instance), a new SDP file must be written, or clients will have trouble connecting to the broadcast stream.
In the absence of a filename argument, a Save dialog will be presented. Audio codec for streaming The audio codec for streaming (default = qdesign2)
The available codec types are none, raw, big16, little16, float32, float64, 24bit, 32bit, little32, mace3, mace6, cdxa4, cdxa2, ima, ulaw, alaw, adpcm, dviima, dvaudio, qdesign, qdesign2, qualcomm, mp3, vdva, mpeg4. Audio enable flag Audio enable flag (default = 0)
This flag is only active in mode 2 (Sequence Grabber source mode) and determines whether sound will be streamed, as well as image. Audio IP address Audio IP address (default = variable)
In multicast mode (the default. See unicast, below), this IP address is automatically assigned, and read-only, and refers to the special multicast address client computers access to reach your broadcast.
In unicast mode, this IP address should be set to the IP address of the single client computer. Audio broadcast port number Audio broadcast port number (default = 8556)
The network port to be used by the audio portion of the broadcast stream. Audio bitrate Audio bitrate (default = 16)
16 = 16-bit audio
8 = 8-bit audio Audio channel selection Audio channel selection (default = 2)
1 = mono audio
2 = stereo audio Video codec for streaming The video codec for streaming (default = h263)
The following list of codecs is deprecated (retained for reference). See codeclist, below, for the preferred method to list valid system codecs.
The available codec types are raw, cinepak, graphics, animation, video, componentvideo, jpeg, mjpega, mjpegb, sgi, planarrgb, macpaint, gif, photocd, qdgx, avrjpeg, opendmljpeg, bmp, winraw, vector, qd, h261, h263, dvntsc, dvpal, dvprontsc, dvpropal, flc, targa, png, tiff, componentvideosigned, componentvideounsigned, cmyk, microsoft, sorenson, indeo4, argb64, rgb48, alphagrey32, grey16, mpegyuv420, yuv420, sorensonyuv9 and mpeg4. Report the available video codecs The valid video codecs available on the system
Sending the message getcodeclist will cause a list of all valid codecs (that is, those with a functioning compressor component) to be reported from the dumpout. This list is guaranteed to contain only working codecs, and should be used in preference to the old, static codec list. Data rate in frames/second Sets the data rate in frames/second. The rectangular portion of the streaming image to be drawn to when an incoming matrix is received The rectangular portion of the streaming image to be drawn to, when an incoming matrix is received. (default = 0 0 (image width) (image height))
The proportions of the rectangle are expressed in the form left top right bottom. All values are relative to the top left corner of the viewing area of the streamed image. Interpolation flag Interpolation flag (default = 0)
Video IP address Video IP address (default = variable)
In multicast mode (the default. See unicast, below), this IP address is automatically assigned, and read-only, and refers to the special multicast address client computers access to reach your broadcast.
In unicast mode, this IP address should be set to the IP address of the single client computer. Keyframe rate Keyframe rate (default = 50)
If set, the jit.qt.broadcast object will attempt to configure the video compressor to use the specified keyframe rate. Keyframes (temporal compression) are not available to all codecs. Streaming source mode Streaming source mode (default = 0)
0 = matrix input
1 = Hinted Movie input (uses the movie attribute to choose a pre-hinted source movie)
2 = Sequence Grabber input (uses an attached camera as the streaming source)
Modes 1 and 2 permit audio streaming, as well. Source movie for mode 1 Source movie for mode 1 (default = "")
If no movie is specified when setting this attribute, a File dialog will be presented. Movies must be hinted, to be used with the jit.qt.broadcast object. See Tutorial 51: Broadcasting for more information. Matrix preview flag Matrix preview flag (default = 0)
If set, an incoming matrix will be copied to the object's output matrix (with srcrect, interp or dstrect transformations) when the jit.qt.broadcast object is streaming. Otherwise, the matrix is simply passed through the object. Only functional in mode 0. Audio sample rate Audio sample rate (default = 8000)
48000 = 48kHz
44100 = 44.1kHz
32000 = 32kHz
22050 = 22.050kHz
22254 = 22kHz
16000 = 16kHz
11127 = 11kHz
11025 = 11.025kHz
8000 = 8000 Hz Broadcast dimensions The dimensions of the broadcast (default = 160 120)
Codec spatial compression quality Codec spatial compression quality (default = 2 (normal))
0 or min = minimum
1 or low = low
2 or normal = normal
3 or high = high
4 or max = maximum
5 or lossless = lossless

Note that minimum quality is, in many cases, the codec's default quality. Use "low" quality for consistent results. Rectangular section of the incoming matrix to compress and stream The rectangular section of the incoming matrix to compress and stream (default = 0 0 (movie width) (movie height)) Broadcast stream name as displayed in the stream's URL Name of the broadcast stream, as displayed in the stream's URL (default = "Jitter")
Codec temporal compression quality Codec temporal compression quality (default = 2 (normal))
0 or min = minimum
1 or low = low
2 or normal = normal
3 or high = high
4 or max = maximum
5 or lossless = lossless

Note that minimum quality is, in many cases, the codec's default quality. Use "low" quality for consistent results. Packet time to live Packet time to live (default = 255)
Unicast broadcast flag Unicast broadcast flag (default = 0)
If set, the jit.qt.broadcast object will broadcast in unicast mode. In this mode, the vip (and aip, if used) refer to a single client computer, which will be able to receive your broadcast. In multicast mode (the default), as many clients as your system's bandwidth can support will be able to access the stream. Destination rect flag Destination rect flag (default = 0)
When the flag is set, the dstrect attributes are used when compressing an input matrix for streaming. Source rect flag Source rect flag (default = 0)
When the flag is set, the srcrect attributes are used when compressing an input matrix for streaming. The proportions of the rectangle are expressed in the form left top right bottom. All values are relative to the top left corner of the viewing area of the incoming matrix. Video codec for streaming The video codec for streaming (default = h263)
Synonym for codec, above. Video enable flag Video enable flag (default = 1)
This flag is currently ignored. Video IP address Video IP address (default = variable)
Synonym for ip, above. Video broadcast port number Video broadcast port number (default = 8554)
The network port to be used by the video portion of the broadcast stream.
