On this page you can determine which FOURCC matches which video codecs/directshow filters. Use a media inspection tool such as AVI codec to identify the FOURCC.
Filters/decoders (as well as codec packs) generally are not listed here matched to FOURCCs. 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 FOURCCs.
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 are not 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.
