Be sure to copy the files into the directory you specified for streaming.

Important QuickTime Streaming Server (QTSS) or Darwin Streaming Server (DSS) cannot be used to natively serve MP3 files on demand (that is, as an HTTP download).

Rather QTSS and DSS support of MP3 streams is intended for shoutcast/icecast-compatible live streams (such as those created by a streaming playlist) or live streams of other compatible MP3 live encoder broadcasters.

If you wish to serve individual MP3 files on demand (not as live streams), simply host the files on a web server in a web documents folder.

Preparing Audio

MP3 audio files can be played back in an MP3 playlist and listened to using iTunes or another compatible streaming MP3 player.

To prepare MP3 files:

1Open the audio file using software that can convert it to MP3 format.

2Save the audio files as MP3 files.

3Make sure all audio uses the same encoding, sampling rate, compression, and bit rate.

4Copy all prepared audio files to the media directory on your streaming server.

Streaming Media Files With Multiple Sources

QuickTime movies often use content from several media files. For example, a video clip can be combined with music stored separately from the video. When you export a QuickTime movie, make it a “self-contained” file so that it includes all the source media. This improves server performance.

If, for some reason, you cannot export the movie as self-contained, here’s what you can do.

To stream movies that are not self-contained:

1Copy all the files needed by the movie to the same folder or directory.

2Store all the files in the directory on your server that you specified as the media directory in Streaming Server Admin.

Streaming File Formats Like .avi, .text, and .wav

If you have QuickTime Pro (a set of advanced features available with QuickTime Player), you can apply hinting to .avi, .text, .wav, and other file formats. Hinting allows you to stream a non-.mov file using QTSS or DSS while retaining the original file.

To hint a file, you must import it into QuickTime Player and then export it as a hinted movie.

QuickTime Streaming Server Darwin Streaming Server specifications

Apple QuickTime Streaming Server, also known as Darwin Streaming Server, is a pivotal technology in the realm of multimedia streaming. Developed by Apple Inc., this open-source server software is designed specifically for the efficient delivery of video and audio content over the internet. One of the standout features of Darwin Streaming Server is its capability to stream content using the QuickTime file format, which is widely adopted for rich media applications.

A core characteristic of Darwin Streaming Server is its support for the Real-Time Streaming Protocol (RTSP). This protocol enables the server to communicate effectively with user clients, ensuring smooth playback of multimedia content. RTSP also allows for advanced streaming capabilities, such as pause, rewind, and fast forward, providing users with a versatile viewing experience.

Darwin Streaming Server is built on a highly modular architecture that enhances its scalability and flexibility. It can easily handle multiple simultaneous streams, making it suitable for both small-scale projects and large-scale broadcast environments. The server can efficiently manage bandwidth, optimizing the delivery of content even during peak usage times.

Another notable feature of Darwin Streaming Server is its robust integration with Apple’s QuickTime technology. This compatibility enables the seamless distribution of interactive media, which is crucial for applications in education, entertainment, and corporate training.

Additionally, Darwin Streaming Server supports various streaming formats, including MP3 and AAC for audio and H.264 for video. This flexibility allows content creators to deliver high-quality media while maintaining compatibility with various devices and platforms, from desktop computers to mobile devices.

Security is another important aspect of Darwin Streaming Server. It supports encryption protocols, ensuring that sensitive content is protected during transmission. This is particularly valuable for organizations that need to secure proprietary content or deliver private media to specific audiences.

In conclusion, Apple QuickTime Streaming Server, or Darwin Streaming Server, stands out as a powerful tool for multimedia streaming. Its integration of RTSP, compatibility with QuickTime, modular architecture, and robust security features make it an ideal choice for businesses and content creators looking to deliver high-quality streaming experiences.
