fender75	Posted - Feb 08 2019 : 02:32:23 Hi , I'm having a very strange behavior with imageenview. I have an imageEnView and I load a video like in the demo example and I play it with run if the user press a key, I hide the imageenview and I show a TImage with a green light loaded when the user press again, I load a new video , I hide the TImage and I show again the ImageEnView and I play the new video. The problem is that when I start playing the new video, I still see the video loaded before (the last frame before the new video load) then the new video plays well. ¿How can I avoid that? I don't know how should do it When I have to play the new video, I don't want to see any frame from the video loaded before the "green light" could you help me? thanks so much

xequte	Posted - Feb 19 2019 : 14:39:29 Hi Unfortunately ImageEn is simply passing on the events as it receives them from Windows. Nigel Xequte Software www.imageen.com
fender75	Posted - Feb 19 2019 : 04:29:48 Hi, I'm having some trouble because the IEEC_COMPLETE is called about 5 seconds later the video has been played. What should I do? I'm playing the video the same way in the videoplayer demo thanks I'm using this code procedure TFMasterMonitor.ImageEnView1DShowEvent(Sender: TObject); var event: integer; begin with ImageEnView1.IO.DShowParams do if Connected then while GetEventCode(event) do case event of IEEC_COMPLETE: begin Stop; Disconnect; ImageEnView1.ClearAll; application.ProcessMessages; if (playAllVideos) then begin inc (myLastVideoID); application.ProcessMessages; playAllVideosNext; end end; end; end;
xequte	Posted - Feb 14 2019 : 04:05:34 Hi You should not need to set these properties twice: EnableSampleGrabber := true; RenderAudio := true; But the methods are all needed. Nigel Xequte Software www.imageen.com
fender75	Posted - Feb 13 2019 : 03:22:00 Hi, thanks so much! Every time I play a video from the playlist I have to do execute all this code? with ImageEnView1.IO.DShowParams do begin if State = gsRunning then begin Stop; Disconnect; end; FileInput := myFileName; EnableSampleGrabber := true; RenderAudio := true; Connect; if Show_Position_By_Frame then ImageEnView1.IO.DShowParams.TimeFormat := tfFrame; Position := 0; // Pause; // This shows first frame ImageEnView1.IO.DShowParams.Run; end; I mean , stop, disconnect, renderaudio, connect.... thanks again
xequte	Posted - Feb 11 2019 : 19:38:46 Hi I'm afraid I cannot reproduce that issue using your code. Please send me a simple demo that shows it. To make a playlist, simply use the DShowEvent to detect when playback completes, and the start the next video procedure Tfmain.ImageEnView1DShowEvent(Sender: TObject); var event: integer; begin if ImageEnView1.IO.DShowParams.Connected then while ImageEnView1.IO.DShowParams.GetEventCode(event) do case event of IEEC_COMPLETE: PlayNextVideo(); end; end; Nigel Xequte Software www.imageen.com
fender75	Posted - Feb 11 2019 : 02:59:20 Hi, I use this code to load and play a video procedure Tfmain.Open1Click(Sender: TObject); begin with ImageEnView1.IO.DShowParams do begin if State = gsRunning then begin Stop; Disconnect; end; FileInput := myFileName; EnableSampleGrabber := true; RenderAudio := true; Connect; if Show_Position_By_Frame then ImageEnView1.IO.DShowParams.TimeFormat := tfFrame; Position := 0; // Pause; // This shows first frame ImageEnView1.IO.DShowParams.Run; end; end; by the way, it is possible to do a playlist for playing 3 videos one after another? I don't know how exactly do this thanks so much
xequte	Posted - Feb 08 2019 : 16:07:17 Hi I cannot reproduce that. Please show me your code. Nigel Xequte Software www.imageen.com
fender75	Posted - Feb 08 2019 : 08:18:15 I used the videoplayer demo example to load and display the video
xequte	Posted - Feb 08 2019 : 04:38:17 Hi What code are you using to display the video (or which of the demos did you base it on)? Nigel Xequte Software www.imageen.com
