FAQ

Cannot play certain file type or URL

WPF-MediaKit itself does not play any media, it's the problem of the codecs used. E.g. can any other DirectShow player (like MPC-HC) play that URL/file? If not, then the WPF-MediaKit cannot play it, too.

Cannot play transparent mov, avi

LAVFilters does not return alpha channel, for some workarounds, see #87 and #45.

See Wiki HW Acceleration.

How to grab a screenshot

Use MediaUriPlayer.CloneSingleFrameD3DImage() or, when offscree, see the Wiki Headless Examples. Do not use MediaDetector since it does not work for all file formats (happy to see some PR to fix that).

How to use custom MediaUriPlayer subclass

You may modify some behaviour to subclass the MediaUriPlayer. Then subclass the MediaUriElement, too and override the OnRequestMediaPlayer to return your player.

SpeedRatio is ignored

It depends on the codec used. Some codecs support speed ratio up to 4x, some just up to 2x. See #34, #88.

VideoCaptureElement.EnableSampleGrabbing does not work
