Technical Q&A QTW25
Components and Decompressors, Optimization Options in Codecs

Q My codec is never given any optimization options other than OPT_RAW. In other words, the optt field in the decompression parameter structure is always set to this value. How do I support OPT_BMP and different bitmap decompression strategies?

A You need to explicitly define the codec capabilities for your codec so that the capabilities state that OPT_BMP and other supported optimization options are supported by your codec. See the Data structures section of the Components and Decompressors QuickTime for Windows document for more details about the CodecCapabilities data structure.
