Hello,

I want to write code that crop 5 Frames from a video file and save it in a new Video file.

But my Code doesnt work. What is false?

Code: Select all

AVIFile.s = "C:\Uen.avi" 
AVIFile1.s = "C:\Users\Joel\Desktop\testvideoframe.avi" 
  
AVIFileInit() 

If AVIFileOpen(@FileBufferID, AVIFile.s, #OF_SHARE_DENY_WRITE, 0) = #AVIERR_OK 
   If AVIFileInfo(FileBufferID, AviInfo.AVIFile_Info, SizeOf(AVIInfo)) = #AVIERR_OK     
    EndIf 
  
EndIf 


If AVIFileGetStream(FileBufferID, @AVIStreamBuffer.l, #streamtypeVIDEO, 0) = #AVIERR_OK 
frameObject = AVIStreamGetFrameOpen.l(AVIStreamBuffer.l, #AVIGETFRAMEF_BESTDISPLAYFMT )

firstFrame = AVIStreamStart(AVIStreamBuffer) 
numFrames = AVIStreamLength(AVIStreamBuffer) 

*bm = AVIStreamGetFrame(frameObject, 1) 
Debug *bm
        
AVIFileOpen(@FileBufferID1, AVIFile1.s, #OF_WRITE | #OF_CREATE, 0)
AVIFileCreateStream(FileBufferID1, @AVIStreamBuffer1.l, @strfff)
AVIStreamWrite(AVIStreamBuffer1.l, 0, 500, *bm, 54394912, $10, 0,0)
AVIFileExit()

I have the old code optimized, but the last command: AVIStreamWrite() are the result of -29381 back.

Do you have an idea what the code is wrong

Code: Select all

#streamtypeVIDEO = 1935960438 
#streamtypeAUDIO = 1935963489 
#streamtypeMIDI = 1935960429 
#streamtypeTEXT = 1937012852

#AVIERR_NOCOMPRESSOR=$80000000 Or $40000 Or ($4000 + 113) 
#AVIERR_MEMORY=      $80000000 Or $40000 Or ($4000 + 103) 
#AVIERR_UNSUPPORTED= $80000000 Or $40000 Or ($4000 + 101)
