|
VideoFiltersFfdShowDecoderSet method |
|
Remarks
If FFDSHOW is installed inside the system, modifies the FFDSHOW decoder set for a certain video format. You can obtain the current selected decoder through the VideoFiltersFfdShowDecoderGet 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.
