VideoFiltersFfdShowDecoderGet method |
|
Remarks
If FFDSHOW is installed inside the system, obtains the FFDSHOW decoder set for a certain video format. The current decoder can be changed through the VideoFiltersFfdShowDecoderSet method.
You can know if FFDSHOW is installed by querying the VideoFiltersFfdShowIsAvailable method.
Important note
Since 2016 FFDSHOW filters are no more included inside the K-Lite Codec Pack so this method is now obsolete.
