How to Use Live555 Library for Streaming Applications
Once you have downloaded and installed Live555 Library on your platform, you can use it to build streaming applications. The library provides some ready-made applications that you can use or modify for your needs. These applications are:
Live555 Media Server
This is a RTSP/RTP media server that can stream any supported media file (including MP3, MPEG, H.265, H.264, H.263+, DV or JPEG) from a local file system or from a standard HTTP server. It can also stream live audio and video captured by an input device (such as a microphone or a camera). To run this application, you need to type live555MediaServer <filename>, where <filename> is the name of the media file or device that you want to stream. You can then access the stream from any RTSP client (such as VLC or MPlayer) using the URL rtsp://<server-address>/<filename>.
Live555 Proxy Server
This is a RTSP proxy server that can relay any RTSP/RTP stream from another server to multiple clients. It can also act as a cache for streams that are accessed frequently. To run this application, you need to type live555ProxyServer <rtsp-url>, where <rtsp-url> is the URL of the stream that you want to proxy. You can then access the stream from any RTSP client using the URL rtsp://<proxy-address>/proxyStream.
Live555 HLS Proxy
This is a HTTP Live Streaming (HLS) proxy server that can convert any RTSP/RTP stream from another server to HLS format and serve it to multiple clients. HLS is a protocol that allows adaptive streaming of media over HTTP, which is supported by many devices and applications (such as iOS devices and Safari browser). To run this application, you need to type live555HLSProxy <rtsp-url>, where <rtsp-url> is the URL of the stream that you want to convert. You can then access the stream from any HLS client using the URL
VobStreamer
This is a simple application that can stream a DVD (VOB) file over RTP/UDP. It can be useful for testing purposes or for streaming DVDs without encryption. To run this application, you need to type vobStreamer <vob-filename>, where <vob-filename> is the name of the VOB file that you want to stream. You can then access the stream from any RTP client using the URL rtp://<server-address>/video.
Test Programs
The library also includes some test programs that demonstrate how to use the library for streaming applications. These programs are located in the testProgs subdirectory of the source code directory. Some examples of these programs are:
testRTSPClient: A simple RTSP client that can receive and play any RTSP stream from another server.
testOnDemandRTSPServer: A simple RTSP server that can stream any supported media file from a local file system or from a standard HTTP server.
testMPEG1or2VideoStreamer: A simple application that can stream a MPEG-1 or MPEG-2 video file over RTP/UDP.
testH264VideoStreamer: A simple application that can stream a H.264 video file over RTP/UDP.
testH265VideoStreamer: A simple application that can stream a H.265 video file over RTP/UDP.
testAMRAudioStreamer: A simple application that can stream a AMR audio file over RTP/UDP.
testMP3Streamer: A simple application that can stream a MP3 audio file over RTP/UDP.
