How to get the mediaPlayer to “let go” of a file?
Aug 23, 2015

I have a mediaPlayer control I’m working with on a form that just plays back local .AVI files – no problem – however the last file it played remains “held” by the player no matter what I do – stop playback, clear the file list for the control etc… it does not let go which prevents me from deleting/moving the file in question. I can run the player on a separate form/dialog that I can then dispose of which works but is less than ideal – just looking for the “correct” way to release the file handle here.
Thanks.

Did you tried to call Clear() method of control?

The MediaPlayer control does not have a "clear" method - there are 6 or so methods that contain the word "clear" for clearing audio effects, video effects, dual screen config etc... yes, I did try calling those but the file is still held. I can either empty the file list and add a new dummy file which causes it to let go or dispose of the object - oddly I actually had to resort to forcing the GC to cleanup when I did that or in some cases it still held the file and I couldn't move it.

Difficult to told why that's happen, using Stop method we are fully destroy all DirectShow filters used, so, file must be available.

... and yet its not and it's very easy to reproduce. Just make a WinForm app with a MediaPlayer on it, add a file and start playing it - make a stop button that then calls stop and tries to move the file. It will fail %100 of the time. Here's a chunk of code I just wrote and produces the error no problem - the "breakfast.mg" file is playing at the time - call stop and try to move - no go. You library is clearly not releasing the file...
MediaPlayer1.Stop();
try
{
File.Move("c:\\breakfast.mpg", "c:\\breakfast2.mpg");
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
