YouTube

From MultimediaWiki
Jump to navigation Jump to search

YouTube is a website that allows users to upload video that can then be viewed by other users. Some of YouTube's wild popularity hinges on its accessibility-- it is able to accept multimedia files encoded in an enormous array of formats. Some suspect that YouTube's backend conversion software leverages FFmpeg. FFmpeg supports a wide range of multimedia formats as documented in this Multimedia Wiki. This Wiki page is an effort to determine which multimedia formats can be converted by YouTube's software.

Note that this is an ongoing project and is not exactly an authoritative list of all the formats that YouTube accepts.

Formats That YouTube Fails To Convert

The reason that this list tests so many obscure formats is that YouTube is known to handle an impressive number of obscure formats just fine.

Note that items marked rejected because they were too long are probably results of software malfunction; the samples should not exceed the 10-minute time length (I'm making this assumption based on their relatively small sizes --Multimedia Mike).
