DVD Padding Progress

Can we get a callback for the dvd media padding progress? As it stands now I have no way to update a UI during this phase. All I can do is say "this might take a long time"

Thanks,

Michael

Unfortunately not yet... I'll add padding callback progress to the next StarBurn release however. Drop me a message to anton@rocketdivision.com so we'll arrange how you'd take part in beta fest

I use the Version 2006.10.04 (with Delphi). There are now callback numbers dealing with padding. But I don't find any examples for CN_DVD_MEDIA_PADDING_WRITE_PROGRESS

I tried to use the same code as used for CN_CDVD_WRITE_PROGRESS, but the returned percent value is not correct:

Code:

  case ACALLBACK_NUMBER of
    [...]
    CN_DVD_MEDIA_PADDING_WRITE_PROGRESS: begin
      // Get parameters passed with callback
      FFileSizeInLBs := PInt64(ACallbackSpecial1)^;
      FLBsWritten.QuadPart := PInt64(ACallbackSpecial2)^;

      // Calculate number of percent written
      FCurrentPercent.QuadPart :=
        ((FLBsWritten.QuadPart * 100) Div FFileSizeInLBs);

      // Check if current calculated was already written
      if FCurrentPercent.QuadPart <> g__LARGE_INTEGER__LastWrittenPercent.QuadPart then
      begin
        // Update last written percent with current value
        g__LARGE_INTEGER__LastWrittenPercent.QuadPart := FCurrentPercent.QuadPart;

        // This percent to event
        CallBackEventer.DoWriteProgress(g__LARGE_INTEGER__LastWrittenPercent.QuadPart);
      end;
    end;
    [...]
  end; // case

What format do the parameters for that callback have?

Thanks in advance

Look at the TrackAtOnceFromFile C sample.

Thanks, I thought I searched the C samples too...but it doesn't seem so.

For completeness the working delphi code:

Code:

l__ULONG__TrackPaddingSizeInLBs := PCardinal(ACallbackSpecial1)^;
l__ULONG__TrackPaddingLeftInLBs := PCardinal(ACallbackSpecial2)^;

l__ULONG__PaddingProgressPercent := 100 - (l__ULONG__TrackPaddingLeftInLBs * 100) div l__ULONG__TrackPaddingSizeInLBs;
