Audio file on click map html5/20/2023 ![]() There are two versions of the format, defined in parts 1 and 14 of the specification. MPEG-4 ( MP4) is the latest version of the MPEG file format. ![]() Video codecs supported by MPEG-1 and MPEG-2 CodecĪudio codecs supported by MPEG-1 and MPEG-2 Codec MPEG-1 was introduced in 1992 MPEG-2 was introduced in 1996. The main differences between MPEG-1 and MPEG-2 take place in the media data formats rather than the container format. Otherwise, MPEG-1 and MPEG-2 are not widely used in Web content. On the internet, perhaps the most common use of the MPEG file format is to contain Layer_III/MP3 sound data the resulting files are the wildly popular MP3 file used by digital music devices around the world. The MPEG-1 and MPEG-2 file formats are essentially identical.Ĭreated by the Moving Picture Experts Group (MPEG), these formats are widely used in physical media, including as the format of the video on DVD media. In addition, you can add the codecs parameter to the MIME type string to indicate which codecs are used for the audio and/or video tracks, and to optionally provide details about the profile, level, and/or other codec configuration specifics. These MIME types are the fundamental types for the 3GP media container other types may be used depending on the specific codec or codecs in use. This media container format is derived from the ISO Base Media File Format and MPEG-4, but is specifically streamlined for lower bandwidth scenarios. However, this format is still used for slower networks and for lower-performance phones. However, the improved bandwidth availability and increased data caps on most networks has reduced the need for the 3GP format. The format was designed for use on 3G mobile phones, but can still be used on more modern phones and networks. The 3GP or 3GPP media container is used to encapsulate audio and/or video that is specifically intended for transmission over cellular networks for consumption on mobile devices. Support is also implied only for the container itself, not for any specific codecs. Unless otherwise specified, both mobile and desktop browser compatibility is implied if a browser is listed here. Only older versions of Safari, plus other browsers that supported Apple's QuickTime pluginĬhrome 6, Edge 17 (desktop only), Firefox 4, Opera 10.6, Safari 14.1 (macOS), Safari 15 (iOS).

To learn more about a specific container format, find it in this list and click through to the details, which include information about what the container is typically useful for, what codecs it supports, and which browsers support it, among other specifics. Index of media container formats (file types) mp3 extension, even though their containers are just MPEG. These files use the audio/mp3 MIME type and the. In other cases, a particular codec, stored in a certain container type, is so ubiquitous that the pairing is treated in a unique fashion.Ī good example of this is the MP3 audio file, which is in fact an MPEG-1 container with a single audio track encoded using MPEG-1 Audio Layer III encoding. opus.īut it's still actually just an Ogg file. Not all of these are broadly supported by browsers, however some combinations of container and codec are sometimes given their own file extensions and MIME types as a matter of convenience, or because of their ubiquity.įor example, an Ogg file with only an Opus audio track is sometimes referred to as an Opus file, and might even have the extension. However, you may also encounter MP3, Ogg, WebM, AVI, and other formats. The most commonly used containers for media on the web are probably MPEG-4 (MP4), QuickTime Movie (MOV), and the Wavefile Audio File Format (WAV). The MIME types and extensions for each are listed. Some support only audio while others support both audio and video. While there are a vast number of media container formats, the ones listed below are the ones you are most likely to encounter.
