OGG is a multimedia container format. It’s an open source format, free to be used by anyone without licensing and royalty fees.
The format is developed by the Xiph Org Foundation.
Ogg is derived from the word “ogging” as used in the computer game Netrek.
It means doing something committedly, without worrying about future risks.
Ogg audio has the following extensions – .oga, .ogg and .spx. Ogg audio uses the Ogg Vorbis compression.
Thus audio files in the OGG container are referred to as Ogg Vorbis. Vorbis is the audio codec.
OGG Video (OGV)
Ogg video format has the .ogv extension. Any video file saved in the OGG container format is known as an OGV file.
An OGV file is a video stream with or without audio. It can also include text.
OGV files are often used to play a web page video, employing the HTML<video>tag.
Although OGV has the .ogv extension, in the HTML source code, the .ogg extension is used .
Codecs used with Ogg video include Theora and Divac.
An Ogg video file is not associated with Vorbis like an Ogg audio file.
Theora Compression Format
The free Theora lossy compression format is a versatile one. It has the ability to scale a video from the size of a postage stamp right up to the resolution of high definition (HD) video.
