OGV vs M4A:
|Full name||Ogg Video||Audio-only MPEG-4|
|Developed by||Xiph.org||International Organization for Standardization|
|Type of format||Compressed video||Media container|
|Introduction||OGV file is video file that uses the Xiph.Org's open source Ogg container format; may contain video streams that use one or more different codecs, such as Theora. Theora is a free lossy video compression format. It is distributed without licensing fees.||MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but can also be used to store other data such as subtitles and still images. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files.|
|Technical details||The Theora video-compression format is essentially compatible with the VP3 video-compression format, consisting of a backward-compatible superset. Theora is a superset of VP3, and VP3 streams can be converted into Theora streams without recompression.||Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of non-protected content. M4A is often compressed using AAC encoding (lossy), but can also be in Apple Lossless format.|
