Reducing the sample rate is a way to lower the bitrate of the resulting audio stream. About the URL of the RTSP, please see the explanation as follows. Some additional processing can be done during this process, such as re-scaling, deinterlacing, resampling, etc. This option uses a private extension of the SAP protocol. Stream in multicast the video and dump the audio in a file: Note: You can also combine the es module with the other modules to set-up even more complex solution.

Receive an HTTP/FTP/MMS stream Use one of the following command lines : % vlc -vvv http://example/stream.xyz 4.4.1. Other streams will be streamed using even ports directly above this one. This allows to set the converter to use to encode the subtitle stream. This option allows to crop the lower part of the source video. 4. 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. Design by Made By Argon. To fully understand the complex syntax of VLC's stream output, please look at the examples in the next section. This module can be used to duplicate the stream, and so process it through several different chains. This option allows you to specify the codec the audio tracks of the input stream should be transcoded to. This option allows to set the bitrate of the transcoded audio stream, in kbit/s. This page was last edited on 19 August 2020, at 00:07. 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. This selects the transport protocol to carry RTP packets. This option allows to set the UDP port used to send the first elementary stream. Instead of clicking Play, expand the drop down to choose Stream. Running the command vlc --help will create a .TXT file containing all the command-line options. This option has to be set.

See mux options of the standard module for a description of the available method. GUI. 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. Step by Step Instructions. Please have a look at the description of the VLM module for that. You can chain modules to enhance the possibilities. This option enables RTP/RTCP multiplexing (see draft-ietf-avt-rtp-and-rtcp-mux), i.e. Now that we have a command line that records a stream and stops after a given duration, we can schedule our first recording. will adjust input_file gamma to 1.5, resize the video size (resolution) by 0.67 (e.g. 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? 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). The basic transcoding is an mp3 stream from the file you select (if it is a video file, then the video is ignored). This option allows to crop the left part of the source video while transcoding. 1. Open up VLC, say on your Android device, and open the menu, and choose Stream. This port has to be even. If you don't understand their description, this certainly means that you don't need them. But if there are more of them, link will be excessively loaded. 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. 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. Here is the complete description of VLC's command line and how to use it. Depending on the bitrate of the original stream and of the options chosen, transcoding can be a very CPU-intensive task. This option can be particularly useful to help reduce the bitrate of a stream. VLC is one of the most loved media players out there.

This can be the address of a host or a multicast group. These option parameters are also often very advanced settings. In this case you should use multicast, when one stream is generated for an arbitrary number of listeners. 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 … Use this option to set the location where the video elementary streams should be saved, sent, or made available. Several criteria can be given, by separating each of them with a comma. The argument is the Y coordinate of the first line to be cropped. Some icons are licensed under the CC BY-SA 3.0+. By using the4 GUI media->stream I was able to manually start the stream. on top of the video. 3.
