Re: [Pyobjc-dev] QTMovie: userData, annotations, and types?

[Jep H. <je...@gm...>]

Great suggestion for a starting point to get more familiar with the QTMovie class. The items I asked about are actually not covered on that page — I'm secretly hoping they are used to get around the use of the metadata API.

Regarding the valid Types, I think they *may* be referring to this:

inDataType
A data type from the following list:

kQTMetaDataTypeBinary               = 0,
kQTMetaDataTypeUTF8                 = 1,
kQTMetaDataTypeUTF16BE              = 2,
kQTMetaDataTypeMacEncodedText       = 3,
kQTMetaDataTypeSignedIntegerBE      = 21,
kQTMetaDataTypeUnsignedIntegerBE    = 22,
kQTMetaDataTypeFloat32BE            = 23,
kQTMetaDataTypeFloat64BE            = 24

Thank you for the help.
