GF_CodecID

enum GF_CodecID

Codec ID identifies the stream coding type. The enum is divided into values less than 255, which are equivalent to MPEG-4 systems ObjectTypeIndication. Other values are 4CCs, usually matching ISOMEDIA sample entry types.

Unless specified otherwise the decoder configuration is:

• the one specified in MPEG-4 systems if any
• or the one defined in ISOBMFF and derived specs (3GPP, dolby, etc) if any
• or NULL
