[dutch]

Dear All,

I try to use WMPlayer.OCX and play loop for better solution than GIF file. But it has black frame before start playing the vdo.

How to fix black frame as vdo clip?

Thanks in advance for any help and suggestion.

Dutch,

I noticed a short loading-time during the loops

here is a free Video-editor / cutter to check the frames
at the beginning and end.

Dear Uwe,

Thank you for your reply but there is not black frame in vdo (mp4). I try Avidemux but no black frame. I try another mp4, it has got the same result.
I guess, it is the frame of object before start.

This is the mp4 file.

Dutch,

I tested the wmplayer as a exe-file.
the problem seems to be the ocx-usage.

Just a idea :
1. use avidemux and select the file
2. append the file as often to the needed length
3. save these loaded files, they will be all connected to just 1 file
storage settings :
Video- and Audio-codec = Copy
Autput-format = MP4 muxer
For the created longer file You don't need a loop

Dear Uwe,

Thank you so much for your idea. Firstly I try GIF file but it has 25 frames per second. It doesn't smooth as MP4. I try to get the best result.

Thanks once again for your solution.

Dutch,

I just tested and works fine
just append as often to get the needed length.

I tryied too, and the only solution I found is do manually the loop:

Code: Select all  Expand view

      if oActiveX :controls:currentPosition > oActiveX :currentMedia:duration - 0.01
         oActiveX :controls:currentPosition := 0
      endif

As they suggest you can create a timer to do this check.

Dear AntoninoP,

Thank you so much AntoninoP and Uwe. It's fixed black frame flicker during loop. But It is still show black frame on start playing.

How do I fixed the first black frame?

Dear AntoninoP and Uwe,

I can fix it now.

- Show in TIMER

Code: Select all  Expand view

DEFINE TIMER oTimer INTERVAL 100 ACTION (if(  oActiveX :controls:currentPosition > oActiveX :currentMedia:duration - 0.01, (oActiveX :controls:currentPosition := 0.01), if(oActiveX :controls:currentPosition > 0.1, oActiveX :Show() , ) ))

- Hide() at DIALOG INIT

Code: Select all  Expand view

  oActiveX = TActiveX():New( oDlg, "WMPlayer.OCX",  nTop, nLeft, nWidth, nHeight )
   oActiveX :Hide()

Dutch,

I'm just thinking about a possible dialog fade-in-effect
for the video that will cover the first frames
just a idea not tested yet.

hi,

did you use

Code: Select all  Expand view

 
   oActiveX:Settings:AutoStart := .T.
   bOldError := ERRORBLOCK( { | e | BREAK( e ) } )
   BEGIN SEQUENCE
      oActiveX:URL := cPlayFile
 

this Way Video start from 0:00 but you can change it to

Code: Select all  Expand view

 
   oActiveX:Settings:AutoStart := .F.
   bOldError := ERRORBLOCK( { | e | BREAK( e ) } )
   BEGIN SEQUENCE
      oActiveX:URL := cPlayFile
      oActiveX:controls:currentPosition := nFirstFrame
      oActiveX:Controls:Play()
