The argument is the number of columns the video should be cropped. This option can only be used if the sap or slp option has been enabled. in Uncategorized Description of the stream output VLC's stream output allows VLC to be used as a streaming server instead of a client ! Now that we have a command line that records a stream and stops after a given duration, we can schedule our first recording. This page was last edited on 14 March 2019, at 04:04. This page was last edited on 19 August 2020, at 00:07. Input RTSP URL in Network Tab. Different kind of processing can be applied to the stream during this process (transcoding, re-scaling, filters, re-muxing…). However, there is something that makes VLC even more special on Linux-the command line. I'm trying to create an overlay of two security camera views onto one video stream, and streaming it out as RTSP protocol. Possible values and item options are the same than for the access option of the standard module (see above). Taking a UDP input and resending it once raw via IPv6 multicast, and once in HLS, This page is part of official VLC media player, MMS / MMSH streaming to Windows 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/Command_Line_Examples&oldid=59430. This option allows to crop the upper part of the source video while transcoding. Stream the mp3 file; Has to be done via command line; mp3 file should play as a loop; Procedure. This option allows to crop the lower part of the source video. This option can be used to set the name that will be displayed on the client receiving the stream. This option can only be enabled with the udp output method. This module saves the stream to a file or sends it over a network, after having muxedit. This option enables RTP/RTCP multiplexing (see draft-ietf-avt-rtp-and-rtcp-mux), i.e. Some icons are licensed under the CC BY-SA 3.0+. This option allows to specify the name of an optional group of streams. 1080x720 to 720x480), convert video using the Theora codec with bitrate @ 2000 kb/s and audio using the Vorbis codec with bitrate @ 128 kb/s, encapsulate the video and audio to an Ogg container and save it to output_file.ogg. This port has to be even. 3. sends and receives RTCP packets on the same port numbers as RTP packets. See mux options of the standard module for a description of the available method. Depending on the bitrate of the original stream and of the options chosen, transcoding can be a very CPU-intensive task. Stream Output. This option has to be set. The basic transcoding is an mp3 stream from the file you select (if it is a video file, then the video is ignored). Only ts is possible for RTP streams. This port has to be even. Schedule your stream recording with the "at" command. This option allows to set the UDP port used to send the first video elementary stream. Today, we are going to see how we may use VLC and its network options to This option allows to give the chain through which the duplicated stream should be processed. 4.4.1. The command line interface: Next: 4.4. It focusses only on internal LAN streaming, using RTSP, UDP and RTP as the streaming solutions, and working via the command line in Linux. vlc on command line. VLC will be the only client able to read this field. To fully understand the complex syntax of VLC's stream output, please look at the examples in the next section. Use this option if you want the SAP announces to be sent using the IPv6 protocol instead of IPv4.

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 location where the video elementary streams should be saved, sent, or made available. on top of the video. This option allows to crop the left part of the source video while transcoding. Stream output includes different modules, each of them having different capabilities. This is a compulsory option. 4. It is streamed via http to localhost:8080/stream.mp3. In the latter case, the stream will be sent to the host doing the RTSP request. I am trying to stream a test file to my pc using Gstreamer. vlc stream command line example . This option allows to set the UDP port used to send the first audio elementary stream. Options are : This option can be used to set the TTL (Time to Live) of the sent UDP packets. This option allows to set the number of channels of the resulting audio stream. In this case you should use multicast, when one stream is generated for an arbitrary number of listeners. This port has to be even. 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. By using the4 GUI media->stream I was able to manually start the 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. 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 … VLC needs to be configured to lisiten for incoming streams on a specific port.

By default, RTCP packets are sent and received on the next port. This module can be used to display the stream. This option allows to set the bitrate of the transcoded audio stream, in kbit/s. Download and install VLC. A VLC used as a client will use this field to classify the stream. Use this option if you want to send such announcements. On desktops, it's Media and Open Network Stream.... Then, just enter the address of your stream. ):[Please check this]. 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 you to give the width of the transcoded video, in pixels. 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. To do so, use the "at" command, which schedules commands to be executed once in the future at a specified time. It focusses only on internal LAN streaming, using RTSP, UDP and RTP as the streaming solutions, and working via the command line in Linux.
