RTP Port Devices Driver
-->
For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. To install serial ports and COM ports using these system-supplied components, do the following:
Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port.
To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.
For more information about installing serial ports and COM ports using the Ports device setup class and the Serial function driver, see the following topics:
If a device is disabled, it has a red X across its icon, like the Bluetooth Communications Port in this picture. To enable it, right click on the device and select “Enable.” Afterwards, the device should not have a red X across its icon. Devices can also have issues loading or have device driver problems. 2) Re-connect the Moates device, and allow the drivers to associate with it. Wait about 30 seconds. 3a) Go into the Windows Device Manager, and look under ‘Ports(COM/LPT)’. If there is a ‘USB Serial Port’ listed, right-click on it and select ‘Properties’. If not, carry out step ‘3b’ on this list first.
If you do a custom installation of a COM port, you must comply with the COM port requirements that are defined in Configuration of COM Ports.
Rtp Port Devices Driver Updater
PORT FORWARDING HAS TO BE MADE FOR ROUTER PORTS: 5060 (TCP) – the main port of connection to the server (for Mobotix T24/T25 it is port 5061). It serves for registration and receiving commands from the server. RTP ports (UDP) – see the iRidium project and server set up. Typically, NAT devices will relay packets through that port back to the endpoint that sent the media. Most endpoints, if they receive an RTP packet on the same port that they transmitted RTP from, will recognize that they are behind a NAT and process the media as if it were received on the advertised port.

'wis-streamer' is a standards-compliant RTSP/RTP server applicationthat streams encoded video and audiofrom the LinuxWIS GO7007 driver.This driver supports several low-cost, off-the-shelf hardware video encoder devices,including:- PlextorConvertX TV402U (also EUand JP models)
For open source software for streaming from other hardware encoders - or frompre-encoded files - see the'LIVE555 Streaming Media' software.
Building 'wis-streamer' from source code
Note: This application currently requires a Linux version 2.6 (or greater) kernel.- First, download, build and install theWIS GO7007 driver.
- Download and build the'LIVE555 Streaming Media' libraries.
- Download the'wis-streamer' source code package,and store it in the same directory as the 'live' directory that you unpackedand built in the previous step. (I.e., don't store it in the'live' directory, but store it in the directory that contains'live'.)
- Run:
Downloading a pre-built 'wis-streamer' binary
Apre-built 'wis-streamer' executable binaryfor Linux/x86 is also available.This binary was built for 'Fedora' Linux kernel version 2.6.9, and may or may not workon other Linux versions.No support is provided for this binary; if it doesn't work for you, then build the applicationfrom source instead.Running 'wis-streamer'
Runand the server will initialize with default parameters:unicast streaming;MPEG-4 video (640x480, up to 1.5 Mbps);raw PCM audio (16 bit, 48000 Hz);RTSP server port 8554;assuming a NTSC input source, on input device number 0 (composite video).(See belowfor how to change these parameters.)If the server initializes correctly, it will then print out a'rtsp://' URL that can be used - by a media player client - to play the stream.
Playing the stream
The stream can be played by a standards-compliant RTSP/RTP media player application.The VLC media player is recommended.On Windows and Mac OS, you can also runQuickTime Player.(Also, the'openRTSP'command-line application can be used to examine the RTSP protocol exchange,and/or record the stream's audio and video data.)Support
For questions about the'LIVE555 Streaming Media' libraries,and/or the 'wis-streamer' source code,use thedevelopers' mailing list:'live-devel@lists.live555.com'.(Note that you must subscribe to this mailing list before you can post to it.)
Note, however, that no support is currently provided for theWIS GO70007 encoder driver; please refer to the source code.

Input device selection
When 'wis-streamer' initializes, it prints out the available input devices.By default, 'wis-streamer' reads from 'composite input' (device number 0).To have it read instead from another input device, use the'
-i <input-device-number>' option.By default, the input video source is assumed to be in NTSC format.For other formats, you can specify the input video type using the'-t <video-input-type>'option, e.g. '-t pal'.(To see a list of valid video input types, use '-t help'.)
If the selected input device is a TV tuner, then add the option'-c <band-name>:<channel-name>'to select a TV channel.(To see a list of valid <band-name>s, use'-c help'.To see a list of valid <channel-name>s for a given<band-name>, use'-c <band-name>:help'.)
Video output format
The video encoding format can be specified using one of options'-mpeg1','-mpeg2','-mpeg4' (the default),or'-mjpeg'.Alternatively, use the '-nv' (i.e., 'no video') option to disable video encoding/streaming entirely.To specify the width and height - in pixels - of the captured video, use the'-w <width>'and'-h <height>'options.(The default values are: <width>=640; <height>=480.)
The'-r <bitrate>'optioncan be used to specify a maximum video bitrate (in bits-per-second).(The default maximum video bitrate is 1500000 bps - i.e, 1.5 Mbps.)
The'-R <frame-rate>'option can be used to set the video frame rate (in frames-per-second) generated bythe encoder hardware. The <frame-rate> parameter can be either apositive integer, or a fraction of the form <numerator>/<denominator>(where <numerator> and <denominator> are bothpositive integers). The default frame rate is 30000/1001 fps for NTSC, and 25 fps for PAL or SECAM.When it initializes, 'wis-streamer' will display the actual frame rate generated by the encoder(which might not be exactly the same as the value that was asked for).
Audio output format
The'-f <sampling-frequency>'optionspecifies the audio sampling frequency (in Hz).The default value is 48000 Hz.Rtp Port Devices Driver Windows 7
The streamed audio format can be specified using one of the following options:
- '-pcm'which specifies raw, 16-bit PCM (the default).(Therefore, the resulting audio bitrate is<sampling-frequency>×2×16 bps.)
- '-ulaw'which specifies 8-bit µ-law PCM.(Therefore, the resulting audio bitrate is<sampling-frequency>×2×8 bps.)
- '-mpegaudio <bitrate-in-kpbs>'which encodes and streams MPEG-2 audio, with the specified bitrate- e.g., '-mpegaudio 128'. (Unlike video encoding, which is performed by the WIS encoder hardware,this MPEG audio encoding is done in software, in the 'wis-streamer' application itself.)
- '-aac <bitrate-in-kpbs>'which encodes and streams MPEG-4 AAC audio, with the specified bitrate- e.g., '-aac 128'. (Unlike video encoding, which is performed by the WIS encoder hardware,this MPEG audio encoding is done in software, in the 'wis-streamer' application itself.)
- '-amr'which encodes and streams AMR audio.(Unlike video encoding, which is performed by the WIS encoder hardware,this AMR audio encoding is done in software, in the 'wis-streamer' application itself.)
- '-na' (i.e., 'no audio'), which disables audio entirely.
By default, the server's audio stream is stereo.To stream in mono instead (thereby halving the audio bitrate),use the'-M'option.
Special notes:
- QuickTime Player has a longstanding bug that prevents it from playingµ-law audio (except for the special case of 8000 Hz mono).
- Currently, if AMR audio encoding is requested, then the encoding will be mono only (regardless of whether or not the '-M' option is used).
- There is currently a bug in AAC audio encoding, if mono (the '-M' option) is requested. (Mono AAC audio encoding currently does not work correctly.)
MPEG Transport streaming
As a special case, instead of using the video and audio format optionsnoted above, you can use the'-mpegtransport <audio-bitrate-in-kpbs>'option to specify that the streamed data will be a MPEG Transport Stream,containing MPEG-2 video, and MPEG-2 audio (with the specified bitrate).(If the <audio-bitrate-in-kpbs> parameter is zero, then no audiowill be included in the Transport Stream.)Unicast or multicast streaming
By default, the server streams via unicast.This means that each request (from a client media player) to play the streamcauses a new stream to be transmitted, directly to the client.Note, therefore, that the maximum possible number of concurrent clients is limited by yournetwork bandwidth.Alternatively, if the'-m' option is given, then the server will stream via IP multicast.This means that the server transmits the stream only once, regardless of how manyclients have asked to play it.The benefit of IP multicast is that it allows a potentially unlimited number of concurrentclients.The drawback of IP multicast, however, is that most routers do not support multicastby default,so that - in many cases - multicast streaming will not work outside a single LAN.
Special note:
By default, the server usessource-specific multicast (SSM),using a randomly-chosen SSM IP multicast address.To specify a different multicast address, use the'-A <multicast-address>' option(where <multicast-address> is an IPv4 multicast address, in'dotted quad' form; IPv6 is not yet supported).If the '-A' option is used without '-m', then 'any-source multicast (ASM)'is used instead of SSM.By default, when streaming via multicast, the server uses RTP port number 6000 for video,and 6002 for audio.These port numbers can, however, be changed using the'-v <video-RTP-port-number>'and/or'-a <audio-RTP-port-number>'numbers.(When streaming via unicast, arbitrary (ephemeral) RTP port numbers are used.)
Client user authentication
By default, there are no restrictions on who can request to play the stream.However, one or more'-u <username>:<password>'options can be used to specify valid username-password pairs.If this option is used, then the media player client must enter a valid username and password before it can play the stream.Special note:
- This feature does not cause the audio/video RTP data to be encrypted.
- If you're using the VLC media player client, then the username and password must beentered in the prefix of the 'rtsp://' URL - i.e.,(Note that this causes the username and password to be passed over the network in the clear.)
Miscellaneous options
- The'-brightness <value>','-contrast <value>','-saturation <value>',and'-hue <value>'options can be used to control the video input.If these options are omitted, default values are used.(To see the range of possible values, and the default value,use 'help' for <value>.)
- By default, the server uses (TCP) port number 8554 for RTSP.This, however, can be changed using the'-p <RTSP-port-number>'option.
Special note:
If you run the server as 'root', you can use '-p 554', and the port number will be omitted fromthe 'rtsp://' URL (because 554 is the default port number in 'rtsp://' URLs). - The'-D <stream-description-string>'option can be used to set the textual stream description that gets passed(within a SDP description) to each RTSP client.Some media player clients may choose to display this string (e.g., in a banner).
