Introduction




In this section, I will explain what openrtsp is and what it does, what RTSP is and why it is used for media streaming, and what are the main features and benefits of openrtsp.


What is openrtsp and what does it do?




Openrtsp is a command-line program that can be used to open, stream, receive, and (optionally) record media streams that are specified by a RTSP URL. A RTSP URL is an address that begins with rtsp:// and identifies a media resource on a server. For example, rtsp://example.com/video.mp4 is a RTSP URL that points to a video file on the server example.com.


Openrtsp can be used to perform various operations on the media streams specified by the RTSP URL, such as:



  • Opening: Openrtsp can send a DESCRIBE request to the server to retrieve the session's SDP description, which contains information about the media format, codec, bitrate, etc.



  • Streaming: Openrtsp can send SETUP and PLAY requests to the server to initiate and control the streaming of the media data. Openrtsp can also send PAUSE, TEARDOWN, SEEK, or GET_PARAMETER requests to manipulate the streaming session.



  • Receiving: Openrtsp can receive the media data from the server using RTP (Real-time Transport Protocol) or RTCP (Real-time Control Protocol). Openrtsp can handle different media formats, codecs, and network conditions.



  • Recording: Openrtsp can optionally write the received media data into separate output files, named according to their MIME type. For example, if the session contains an MP3 audio stream and an MPEG video stream, Openrtsp will create two output files named audio-MP3 and video-MPEG.



Openrtsp is part of the live555 project, which is a set of open source C++ libraries for multimedia streaming, using open standard protocols (RTP/RTCP, RTSP, SIP). The live555 project also includes other programs and tools for RTSP streaming, such as live555MediaServer, live555ProxyServer, testRTSPClient, and testOnDemandRTSPServer. You can find more information about the live555 project on its official website.


What is RTSP and why is it used for media streaming?




RTSP stands for Real Time Streaming Protocol. It is an application-level protocol that allows a client to request and control the delivery of continuous media, such as audio and video, from a server. RTSP is designed to work with RTP (Real-time Transport Protocol), which is a lower-level protocol that carries the actual media data. RTSP can also work with other protocols, such as HTTP or TCP, depending on the implementation.


RTSP is used for media streaming because it provides several advantages, such as:



  • Interoperability: RTSP is based on open standards and can work with different media formats, codecs, and devices. RTSP can also interoperate with other protocols, such as SIP (Session Initiation Protocol), which is used for voice over IP (VoIP) calls.



  • Flexibility: RTSP allows the client to control various aspects of the streaming session, such as playback speed, direction, position, quality, etc. RTSP also supports multicast streaming, which means that multiple clients can receive the same media stream from the server.



  • Scalability: RTSP can handle large-scale streaming scenarios, such as live events or video-on-demand services. RTSP can also use proxy servers or caches to reduce the load on the origin server and improve the performance and reliability of the streaming session.



  • Security: RTSP can use encryption and authentication mechanisms to protect the privacy and integrity of the media streams. RTSP can also use firewalls or NATs (Network Address Translators) to prevent unauthorized access or interference with the streaming session.



You can find more information about RTSP on its official website or in its RFC document.


What are the main features and benefits of openrtsp?




Openrtsp is a simple and powerful program that can be used for RTSP streaming. Some of the main features and benefits of openrtsp are:



  • Easy to use: Openrtsp can be run from the command line with minimal arguments. You only need to provide the RTSP URL of the media stream that you want to open, stream, receive, or record. Openrtsp will handle the rest of the details for you.



  • Customizable: Openrtsp can be configured with various options and parameters to suit your needs and preferences. You can specify the output file names, formats, codecs, bitrates, etc. You can also adjust the streaming behavior, such as timeout values, buffer sizes, transport protocols, etc.



  • Compatible: Openrtsp can work with different types of media streams, such as MPEG-1/2/4, H.264/AVC, H.265/HEVC, AAC, MP3, AMR, etc. Openrtsp can also work with different types of servers, such as Darwin Streaming Server, Wowza Streaming Engine, VLC Media Player, etc.



  • Free and open source: Openrtsp is part of the live555 project, which is licensed under LGPL (GNU Lesser General Public License). This means that you can use openrtsp for free and modify its source code if you want to. You can also contribute to the development and improvement of openrtsp and other live555 programs.



In summary, openrtsp is a great tool for anyone who wants to stream or record media streams using RTSP.


How to use openrtsp on windows




In this section, I will show you how to download and install openrtsp on windows, how to run openrtsp from the command line, how to stream and record RTSP media streams using openrtsp, and how to use various options and parameters for openrtsp.


How to download and install openrtsp on windows




There are two ways to download and install openrtsp on windows: using a pre-compiled binary or compiling the source code yourself.


The easiest way is to use a pre-compiled binary, which is a ready-made executable file that you can run without any additional steps. You can download the latest version of openrtsp windows binary from this link. The file name is openRTSP.exe and it is about 1.5 MB in size. You can save it in any folder that you want, such as C:\Program Files\openrtsp.


The alternative way is to compile the source code yourself, which is a more advanced and flexible method that allows you to customize or modify the program. You will need to download the live555 source code from this link. The file name is live.2023.06.13.tar.gz and it is about 6.5 MB in size. You will also need to install a C++ compiler, such as Visual Studio or MinGW, and a make tool, such as nmake or GNU make, on your windows system. You can follow the instructions on this page to compile the live555 source code and generate the openrtsp executable file.


How to run openrtsp from the command line




To run openrtsp from the command line, you will need to open a command prompt window and navigate to the folder where you saved or compiled the openrtsp executable file. For example, if you saved it in C:\Program Files\openrtsp, you can type cd C:\Program Files\openrtsp in the command prompt window.


Then, you can type openRTSP followed by the RTSP URL of the media stream that you want to open, stream, receive, or record. For example, if you want to stream and record a video from a RTSP server at rtsp://example.com/video.mp4, you can type openRTSP rtsp://example.com/video.mp4 in the command prompt window.


You can also add various options and parameters after the RTSP URL to configure the behavior of openrtsp. For example, if you want to specify the output file name as myvideo.mp4, you can type -o myvideo.mp4 after the RTSP URL. If you want to see a list of all available options and parameters for openrtsp, you can type -h or --help after openRTSP.


How to stream and record RTSP media streams using openrtsp




To stream and record RTSP media streams using openrtsp, you will need to provide a valid RTSP URL of the media stream that you want to access. You can find RTSP URLs from various sources, such as online video platforms, IP cameras, media servers, etc. You can also create your own RTSP URLs using tools like VLC Media Player or live555MediaServer.


Once you have a RTSP URL, you can use openrtsp to perform different operations on the media stream, such as:



  • Opening: By default, openrtsp will send a DESCRIBE request to the server and display the session's SDP description on the command prompt window. This will show you information about the media format, codec, bitrate, etc. of the media stream.



  • Streaming: By default, openrtsp will also send SETUP and PLAY requests to the server and start streaming the media data from the server. You will see messages like Sending request: SETUP rtsp://example.com/video.mp4/track1 RTSP/1.0 and Received 1000 bytes of complete MPEG video data on the command prompt window. This means that openrtsp is successfully streaming the media data from the server.



  • Receiving: By default, openrtsp will receive the media data from the server using RTP (Real-time Transport Protocol) or RTCP (Real-time Control Protocol). Openrtsp will handle different media formats, codecs, and network conditions. You will see messages like Received a complete MPEG video frame: Presentation time: 00:00:01.000 and Received a complete MP3 audio frame: Presentation time: 00:00:01.000 on the command prompt window. This means that openrtsp is successfully receiving the media data from the server.



  • Recording: By default, openrtsp will also write the received media data into separate output files, named according to their MIME type. For example, if the session contains an MP3 audio stream and an MPEG video stream, openrtsp will create two output files named audio-MP3 and video-MPEG. You can specify the output file names using the -o option. For example, if you want to name the output files as myaudio.mp3 and myvideo.mp4, you can type -o myaudio.mp3 -o myvideo.mp4 after the RTSP URL. You can also specify the output file format using the -F option. For example, if you want to record the media stream as a single MP4 file, you can type -F mp4 after the RTSP URL.



To stop streaming and recording the media stream, you can press Ctrl-C on the command prompt window. Openrtsp will send a TEARDOWN request to the server and close the streaming session. You will see messages like Sending request: TEARDOWN rtsp://example.com/video.mp4 RTSP/1.0 and Closing output files... on the command prompt window. This means that openrtsp has successfully stopped streaming and recording the media stream.
