QTW 25 - Components and Decompressors, Optimization Options in Codecs (no date given)
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 differenced 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.
