At the end of playing the video file, I get "IEEC_COMPLETE" event.
But this event does not occur at the end of the animated GIF.
How to fix it and stop GIF animation at the end?

Hi

What code are you using?

ImageEnView1->IO->DShowParams->FileInput = OpenImageEnDialog1->FileName;
ImageEnView1->IO->DShowParams->EnableSampleGrabber = true;
ImageEnView1->IO->DShowParams->RenderAudio = true;
ImageEnView1->IO->DShowParams->Connect();
ImageEnView1->IO->DShowParams->Run();


void __fastcall TForm1::ImageEnView1DShowEvent(TObject *Sender)
{
int event;
if (ImageEnView1->IO->DShowParams->Connected)
{
while (ImageEnView1->IO->DShowParams->GetEventCode(event))
{
if (event == IEEC_COMPLETE) Stop1Click(this); //call STOP button
}
}
}

Hi

This appears to be a feature of DirectShow. It continually loops animated GIF files and so does not raise an IEEC_COMPLETE event.

You don't need to use DirectShow to play animated gif files, you can just use:

ImageEnView1.IO.LoadFromFile( 'anim.gif' );
ImageEnView1.Playing := True;

I tried to use the method you proposed, but it loads a animated GIF file several times slower.
