Posted on 24/01/2021 . This option allows to specify subtitle format the subtitles tracks of the input stream should be converted to. Use this option if you want to send such announcements. However, there is something that makes VLC even more special on Linux-the command line. This option allows to set the UDP port used to send the first video elementary stream. Transcode the input stream, display the transcoded stream and send it to a multicast IP address with the associated SAP announce and an unicast IP address: Display the input stream, transcode it and send it to two unicast IP addresses: Send the input stream to a multicast IP address and the transcoded stream to another multicast IP address with the associated SAP announces: Take a SDI input, and transcode it twice, once in HD, and one in SD and send both on udp. Stream output includes different modules, each of them having different capabilities. It has very extended capabilities : stream in unicast and multicast on an IPv4 or IPv6 network everything that VLC is able to read, via UDP, RTP or HTTP ; VLC is one of the most loved media players out there. By default, each elementary stream is sent as a separate RTP medium, i.e. The basic transcoding is an mp3 stream from the file you select (if it is a video file, then the video is ignored). On desktops, it's Media and Open Network Stream.... Then, just enter the address of your stream. To do so, use the "at" command, which schedules commands to be executed once in the future at a specified time. By default, RTCP packets are sent and received on the next port. Some icons are licensed under the CC BY-SA 3.0+. The exact meaning of this option depends on the value of the access-video option and is the same as for the url option of the standard module (see above). Take a SDI input, and restreaming it once in raw and transcoding it for the second. This option can be particularly useful to help reduce the bitrate of a stream. This option allows the destination UDP address to be given. The most I get is a black screen with the correct time of the video. Receive an HTTP/FTP/MMS stream Use one of the following command lines : % vlc -vvv http://example/stream.xyz This option has to be given, unless the sdp=rtsp://option is given (see below). GUI. If you want to see the Generated Stream Output String, Use Open Network Stream and change your tab to File. Do not confuse this option with senc/scodec that transcode the subtitles and stream them. You can also use this to get more exhaustive list: vlc -H If you look for help, on a particular module, you can also use vlc -p module --advanced --help-verbose --help-verbose explains things. These option parameters are also often very advanced settings. This module can be used to send a stream using the RTP (Real Time Protocol) protocol (see RFC 3550). You can use this option to introduce a delay in the display of the stream. This module can be used to display the stream. in Uncategorized Opening a file Start VLC with : ... To receive an unicast UDP stream (sent by VLS or VLC's stream output), start VLC with : % vlc -vvv udp:[@:server_port] Possible values and item options are the same than for the mux option of the standard module (see above). This option allows to give the chain through which the duplicated stream should be processed. Here is the list of the modules currently available : Each of these modules may take options. Different kind of processing can be applied to the stream during this process (transcoding, re-scaling, filters, re-muxing…). Free, open source and compatible with almost every operating system, it can do almost everything that one expects it to do and sometimes even more. Use this option to set the encapsulation method used for the audio elementary streams. Let’s start with the basics. Podcast 302: Programming in PowerPoint can teach you a few things. Here is the meaning of the dst option depending on the parameter used for the access option: Use this option if you want VLC to send SAP (Session Announcement Protocol) announces. vlc -vvv multiple_program_input_stream --sout'#duplicate {dst=rtp {mux=ts,dst=239.255.12.42},select="program=12345",dst=rtp {mux=ts,dst=239.255.12.43},select="video,program=1234-2345"}' This command sends the program of the input stream which id is 12345 to 239.255.12.42 and all video programs with id between 1234 and … This duplicate chain will only output the non video elementary streams belonging to the programs which PID are between 100 and 200. Uncategorized. I'm trying to create an overlay of two security camera views onto one video stream, and streaming it out as RTSP protocol. This allows to set the encoder to use to encode the audio stream. This option allows to set the UDP port used to send the first elementary stream. For example, if you want to stream an audio CD in Ogg/Vorbis over HTTP: VLC media player can connect to this by using the following url: mmsh://server_ip_address:8080. 1. Possible values and item options are the same as for the mux option of the standard module (see above). This option allows to crop the right part of the source video. where ftp://example/stream.xyz is the FTP address of the stream; % vlc -vvv mms://viptvr.yacast.fr/encoderfranceinfo. 4. VLC will be the only client able to read this field. This module can be used to duplicate the stream, and so process it through several different chains. This option can be used instead of both mux-video and mux-audio options, when they share the same setting. Stream output is the name of the feature of VLC media player that allows to output any stream read by VLC to a file or as a network stream instead of displaying it. This option uses a private extension of the SAP protocol. Stream the mp3 file; Has to be done via command line; mp3 file should play as a loop; Procedure. This page is part of official VLC media player, Advanced Streaming Using the Command Line, VLM - Multiple Streaming and Video on Demand, Stream from Encoding Cards and Other Capture Devices, https://wiki.videolan.org/index.php?title=Documentation:Streaming_HowTo/Advanced_Streaming_Using_the_Command_Line&oldid=62061. Here is the syntax that you must use : For example, to transcode a stream and send it, use : In the following documentation, single bullet points represent options and double bullet points represent item options (sub-options) : This module saves the stream to a file or sends it over a network, after having muxed it. Transcode a stream to Ogg Vorbis with 2 channels at 128kbps and 44100Hz and save it as foobar.ogg: Transcode the input stream and send it to a multicast IP address with the associated SAP announce: Display the input stream, transcode it and send it to a multicast IP address with the associated SAP announce: Transcode the input stream, display the transcoded stream and send it to a multicast IP address with the associated SAP announce: To receive the input stream that is being multicasted above on a client: Stream a SDI card to H.264 and AAC in TS on UDP. This option allows to give a contact e-mail address. I have been successful getting vlc to start streaming an RTP on linux using the following command: vlc -vvv filename.mp4 --sout '#rtp{mux=ts,dst=142.92.38.100,sdp=sap,name="TestStream"}' Using this verbatim on Windows did not work. To create overlay effect and to stream video out, I use VLC player v3.0.6 on Windows 10. List of available codecs can be found on the streaming features page. Available options are : This option allows to set the sample rate of the transcoded audio stream, in Hz. The exact meaning of this option depends on the value of the access-audio option and is the same as for the url option of the standard module (see above). TODO: completely outdated All standard operations of VLC should be available from the GUI. This option allows you to give the width of the transcoded video, in pixels. By using the4 GUI media->stream I was able to manually start the stream. VLC needs to be configured to lisiten for incoming streams on a specific port. I used the following command: From the command line it looks like the stream is working, but when I try to play the stream in VLC using: udp://@192.168.2.145:9001 or udp://@:9001 it doesn't play. This options can be used to duplicate only a part elementary streams of a complete stream. This is useful for codecs that don't have support for more than 2 channels, or to lower the bitrate of an audio stream. Click on the text input box labeled Please Enter a Network URL; Type in udp://@:5000 ; Click Play; The above assumes that VLC on your computer is listening on an incoming port 5000 for UDP streams. Click Play button, then the video will display. This option can only be used if the sap option has been enabled. 3.1.3. 4.4.1. This option allows to give various information about the location where the stream should actually be saved or sent. The only subtitle encoder we have at this time is dvbsub. Running the command vlc --help will create a .TXT file containing all the command-line options. Options are : This option can be used to set the TTL (Time to Live) of the sent UDP packets. This can be the address of a host or a multicast group. This option can be used instead of both dst-video and dst-audio options, when they share the same setting. A VLC used as a client will use this field to classify the stream. This option can be used instead of both access-video and access-audio options, when they share the same setting. You can use this module to transcode a stream, e.g., to change its codecs or the encoding bitrates. You can chain modules to enhance the possibilities. This port has to be even. Uses video filter during transcode process. It focusses only on internal LAN streaming, using RTSP, UDP and RTP as the streaming solutions, and working via the command line in Linux. This option allows to give the address of a website with additional information about the stream. In this case you should use multicast, when one stream is generated for an arbitrary number of listeners. SAP is a service discovery protocol, that uses a special multicast address to send a list of available streams on a server. 1. Use this option to set the location where the audio elementary streams should be saved, sent, or made available. However, some complex operations can only be done from the command line and there are situations in which you don't need or want a GUI. This option allows to set the medium used to save or send the stream. The option allows you to define things like full screen, the modules to load, and basically anything you normally access from the menus in the graphical interface. About the URL of the RTSP, please see the explanation as follows. Use this option to specify the name of the stream that will be sent in SAP and SLP announcements. Input RTSP URL in Network Tab. Examples for advanced use of VLC's stream output (transcoding, multiple streaming, etc...). Installed nightly VLC 3.0 (the Renderer couldn't detect the device but command line version is working like a charm) – bakytn Oct 7 '16 at 14:56 I have a stream open, and I am trying to restream it through chromecast. 2. This options uses UDP-Lite instead of UDP as the transport protocol for RTP and RTCP packets. You can use this option to disable audio in the displayed stream. Stream Output. Notice that if you want to launch VLC without any graphical interface, replace “vlc” with “cvlc” in all the commands. No surprises here, the basic syntax for reading a file is If you list more than one file, VLC will read them sequentially as a playlist. Possible values and item options are the same as for the access option of the standard module (see above). Send a stream to a multicast IP address and a unicast IP address: Display the stream and send it to two unicast IP addresses: Send parts of a multiple program input stream: This command sends the program of the input stream which id is 12345 to 239.255.12.42 and all video programs with id between 1234 and 2345 to 239.255.12.43. This is a compulsory option. This option allows to set the bitrate of the transcoded audio stream, in kbit/s. Stream in multicast the video and dump the audio in a file: Download and install VLC. vlc on command line. In the latter case, the stream will be sent to the host doing the RTSP request.

Today, we are going to see how we may use VLC and its network options to This option allows you to give the height of the transcoded video, in pixels. Use this option to set the medium used to save or send the video elementary streams. This option allows to set the way the SDP (Session Description Protocol) file corresponding the the stream should be made available. This option enables RTP/RTCP multiplexing (see draft-ietf-avt-rtp-and-rtcp-mux), i.e. This option allows to set the number of channels of the resulting audio stream. 1. vlc streaming not working on ubuntu. The command line interface: Next: 4.2. Ajustez run-time à la durée en secondes pendant … It is streamed via http to localhost:8080/stream.mp3. Some of the module options (option1 in the example) have to be set, others are optional. This allows to set the converter to use to encode the subtitle stream. Design by Made By Argon. Available options are : Use the append option to append the stream to an existing file instead of replacing it : This option allows you to set the encapsulation method used for the resulting stream. This page was last edited on 14 March 2019, at 04:04. Step by Step Instructions. Instead of clicking Play, expand the drop down to choose Stream. Other streams will be streamed using even ports directly above this one. 4.2.1. Now that we have a command line that records a stream and stops after a given duration, we can schedule our first recording. Some additional processing can be done during this process, such as re-scaling, deinterlacing, resampling, etc. Live Webcam Streaming using VLC on the Command Line The following are notes on using VLC as both server and server to stream a webcam from a ender across a LAN to multiple receivers. This port has to be even. This option allows to enable deinterlacing of interlaced video streams before encoding. The argument is the number of lines the video should be cropped. This option allows to crop the lower part of the source video. You can use this option to disable video in the displayed stream. Use this option to set the medium used to save or send the audio elementary streams. This option allows to set the UDP port used to send the first audio elementary stream. Possible values and item options are the same than for the access option of the standard module (see above). Use this option if you want the SAP announces to be sent using the IPv6 protocol instead of IPv4. The argument is the Y coordinate of the first line to be cropped. The avi muxer in VLC is known to produce corrupt files. The es module can be used to separate the different elementary streams from a stream, and save each of them in a different file or send it to a separate destination. Schedule your stream recording with the "at" command. Please have a look at the description of the VLM module for that. It focusses only on internal LAN streaming, using RTSP, UDP and RTP as the streaming solutions, and working via the command line in Linux @ streaming client side vlc rtp://@:5004 # rtp stream from any source in 5004 port vlc udp://192.168.1.1:5004 # udp stream from 192.168.1.1 in port 500 If all is well, VLC should show a timer in the bottom left corner indicating it is streaming the video. As a consequence, streaming of a real-time transcoded stream can lead to dropped frames or a jerky image and sound in some cases, when running out of resources. I am trying to stream a test file to my pc using Gstreamer. no encapsulation is done. The argument is the X coordinate of the first column to be cropped. % vlc -vvv input_stream --sout '#es{access=rtp,mux=ts,url_audio=192.168.1.2:1212, url_video=192.168.1.2:1213}' on the client side: to receive the audio: % vlc udp://@:1212. to receive the video: % vlc udp://@:1213. VideoLAN software is licensed under various open-source licenses: use and distribution are defined by each software license. Reducing the sample rate is a way to lower the bitrate of the resulting audio stream. ... VLC command line issue. VideoLAN, VLC, VLC media player and x264 are trademarks internationally registered by the VideoLAN non-profit organization. This option allows to specify the name of an optional group of streams. But if there are more of them, link will be excessively loaded. The list of available subpicture filters can be found on the streaming features page. This option has to be set. With previous command, VLC must generate stream for everybody who connects. 3. This selects the transport protocol to carry RTP packets. Here are a few additional global options : The stream output also offers a simplified syntax, with which you can only you use the standard module's main options : where access, mux and url are as defined in the options of the standard module. Several criteria can be given, by separating each of them with a comma. If you don't understand their description, this certainly means that you don't need them. This option allows rendering subtitles directly on the video, while transcoding it. This allows to set the encoder to use to encode the videos stream. No audio from streaming MP4 video using VLC over http. Any of the stream output module described earlier can be used as parameter of this option. Use this option to set the encapsulation method used for the video elementary streams. Option parameters (parameter-option1 in the example) are always optional. The Item options of this modules can be found using the following command line : This option allows to set the number of computer processing threads that should be used to encode the streams. on top of the video. Use one of the following command lines: % vlc -vvv http://example/stream.xyz. Ligne de commande n°4 : Capturez une vidéo avec une ligne de commande VLC en définissant une durée d'enregistrement cvlc -vvv rtp://address:port --start-time=00 --run-time=300 --sout file/ts:test.ts. This option allows to crop the upper part of the source video while transcoding. To fully understand the complex syntax of VLC's stream output, please look at the examples in the next section. This is particularly useful in a duplicate chain, in order to monitor a stream while it is being saved or streamed. Only ts is possible for RTP streams. This option allows to specify the codec the video tracks of the input stream should be transcoded to. See mux options of the standard module for a description of the available method. This option allows to set the encapsulation method used to send the stream. Parameters of vfilter can be found on the Advanced Use of VLC Filters. SLP stands for Service Location Protocol. It focusses only on internal LAN streaming, using RTSP, UDP and RTP as the streaming solutions, and working via the command line in Linux. sends and receives RTCP packets on the same port numbers as RTP packets. This option allows to set the bitrate of the transcoded video stream, in kbit/s. This option can be used to set the name that will be displayed on the client receiving the stream. This option allows the give the ratio from which the video should be rescaled while being transcoded. Depending on the bitrate of the original stream and of the options chosen, transcoding can be a very CPU-intensive task. vlc stream command line example . Click here to go to VLC Homepage. This port has to be even. Although use of RTSP is possible using this module, it won't allow you to make Video On Demand. It is an alternative to SAP for session announcement. Description of the stream output VLC's stream output allows VLC to be used as a streaming server instead of a client ! 2. The argument is the number of columns the video should be cropped. where http://example/stream.xyz is the HTTP address of the stream; % vlc -vvv ftp://example/stream.xyz. This option allows to crop the left part of the source video while transcoding. Separate audio and video in two PS files: Extract the audio track of the input stream to a TS file: Stream in unicast the audio track on a port and the video track on another port (NOTE: This will not only work with VLC 0.8.6 or older - FIXME? This option allows to render some images generated by a so-called subpicture filter (e.g. This option can only be used if the sap or slp option has been enabled. will adjust input_file gamma to 1.5, resize the video size (resolution) by 0.67 (e.g. For criteria that need a parameter, such as es and program, you can also specify a range, using the syntax criteria=num_start-num_end. Available options are: This option allows to set the framerate of the transcoded video, in frames per second; reducing the framerate of a video can help decrease its bitrate. Increasing this number to the amount of processors on the computer (or twice this number on Intel P4 HT processors) should improve transcoding performance. The combination of :sout-keep and dst=gather:std mean that the stream is kept open and subsequent items are played through the same stream. You need to be quite comfortable with command line usage to use this. Windows Media Player can connect to this by using the following url: mms://server_ip_address:8080.
