V_MS/VFW/FOURCC - Microsoft (TM) Video Codec Manager (VCM) You feel we missed support for a very important codec, please tell us on ourĭevelopment mailing list (matroska-devel at ). List of all the codecs we plan to support in the future canīe found on the CoreCodec forum (subject to be changed constantly). In matroska (or will be supported soon), and therfore need a well definedĬodec ID so that all developers supporting matroska will use the same ID. Please, when reading through this list, always keep in mind that the intentionīehind it is NOT to list all existing audio and video codecs,īut more to list those codecs that are currently supported There are 2 different kind of codec 'initialisation' :Įach of these elements contain the same kind of data. The codec works with the coded data in the stream, but also with some codec initialisation. This ID is represent the codec used to encode data in the Track. So please visit his site if you care about Codec IDs.įor each TrackEntry inside matroska, there has to be a CodecID defined.
