OGV vs AAC:
Name OGV AAC
Full name Ogg Video Advanced Audio Coding
File extension .ogv .aac
MIME video/ogg audio/aac
Developed by Xiph.org Bell Labs, Fraunhofer Institute etc.
Type of format Compressed video Audio compression format
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. Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.
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. AAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.
