AVDecVideoThumbnailGenerationMode property
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Enables or disables thumbnail generation mode in a video decoder.
This property is read/write.

CODECAPI_AVDecVideoThumbnailGenerationMode
Remarks
If the value is VARIANT_TRUE, the decoder uses a setting that is optimized to generate thumbnail images quickly. (For example, it might skip B or P frames.) Otherwise, if the value is VARIANT_FALSE, the decoder uses its normal decoding settings.
