Can anyone post code snippet for c# to calculate dvd available space for
Dvd+r, dvd+rw, dvd-r, dvd-rw, and dual layer dvd.
Ex in mb.

Also, can you tell me how get get media type. Is there an enum or something I can use to determine media type(ex dvd=r, dvr-r, etc).

Does the calculation differ on media type and brand

Thanks;
Steve

Hello

Steve

1) We have provided C# examples with our new component StarBurnX OCX which you can download from our link was removed

The StarBurnX component provides the DiscInfo object which keeps information about the media type and free space available on media.

!! We recommend to use the StarBurnX for .Net programming !!

Notify me please if functionality of StarBurnX does not cover all of functionality necessary for you.


2) If you prefer to use SDK directly you should use the SDK function StarBurn_CdvdBurnerGrabber_GetDiscFreeSpace which returns number of free logical blocks on the disc. To convert LB value into Mb you can use SDK constants MODE1_LB_SIZE_IN_UCHARS, MODE2_FORM2_LB_SIZE_IN_UCHARS, MODE2_FORM1_LB_SIZE_IN_UCHARS etc.

((LBSizeValue * LogicalBlockSize)/1024)/1024

where LogicalBlockSize = MODE1_LB_SIZE_IN_UCHARS (or MODE2_FORM1_LB_SIZE_IN_UCHARS etc.)


3) To get type of media you should use the SDK function StarBurn_CdvdBurnerGrabber_GetInsertedDiscType which returns DISC_TYPE enumeration value

Does the calculation differ for discInformation.FreeLBs call based
on it s media type(dvd+r,dvd-r, etc). This is the code that I am using

StarBurn.CDiscInfo discInformation = device.GetDiscInfo();

long dvdSize = discInformation.FreeLBs;
dvdSize = dvdSize * 2048;

Thanks;

For DVD and Blu-Ray and HD-DVD this is right. For CD (data burning mode) - also. For AudioCD & VideoCD you need to multiply not to 2048 (data sector size) but rather to 2352 (audio sector size) and 2324 (video sector size).

But how can I knew what constant should I use?

This is you who knows what exactly you want to burn - AudioCD, DataCD or VideoCD. We don't know

Hmm... the second problem - can't found the StarBurn_CdvdBurnerGrabber_GetDiscFreeSpace function (using Delphi 2007).

What version of the SDK are you actually running? Please check and drop us a line. We'll respond with the updated Pascal header.

Actually, I have just downloaded the latest version from your site right now. So it is 7.2.20 (from 20 february).

Please drop us a message to support@rocketdivision.com and we'd issue you with updated Pascal header.
