MFT_ENUM_TRANSCODE_ONLY_ATTRIBUTE attribute

Specifies whether a decoder is optimized for transcoding rather than for playback.

Currently, this attribute applies only to hardware-based decoders that use the AVStream mini-driver. The attribute is stored in the registry under the decoder's capabilities information. For more information, see the documentation for IGetCapabilitiesKey.

Applications typically do not use this attribute.

Data type

Remarks

If this registry entry is present and equal to 1, the MFTEnumEx function skips the decoder unless the caller specified the MFT_ENUM_FLAG_TRANSCODE_ONLY flag in MFTEnumEx.

The GUID constant for this attribute is exported from mfuuid.lib.
