FOURCC - Four Character Code

On this page you can determine which fourcc matches which video codecs/directshow filters. If you still need to find out which fourcc the unidentified video stream in your multimedia file has, please refer to a program such as MovieCodec Codec Tool or other file inspection programs available in our tools downloads (avicodec, gspot etc.).

Check out the audio tags listing if it is not the video stream causing you problems with a given multimedia file.

If you have a Quicktime file (MOV, QT) or RealPlayer file (RM, RMVB) then in almost all cases all that you will need is to simply download the players in order to playback your file. For codecs specifically for Quicktime (or RealPlayer) that aren't bundled with the player you should still use the table on this page however.

Bundled codecs for Quicktime includes SVQ1: Sorenson and Sorenson 2, SVQ3: Sorenson 3, JPEG: Photo JPEG, RPZA: Apple Video and more. Bundled codecs for RealPlayer includes RV10, RV20: Real Video G2, RV30: Real Video 8, RV40: Real Video 9, RV40: Real Video 10.

Filters/decoders (as well as codec packs) generally aren't listed here matched to FOURCC's. This is bacause they often implement many different codecs in one simple package (ie. ffdshow-tryouts) and it would clutter this page immensely to include them here. This page focuses on matching specific codecs to specific FOURCC's.
