🔸 Description MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially for streaming media. ASF is part of the Media Foundation framework.
🔸 Technical details Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. The format does not specify how the video or audio should be encoded; it just specifies the video/audio stream structure. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives.
