Sorry for the basic question, but is it possible to use LeadTools Multimedia in a web page? Could i create an ActiveX control that users could use to convert video files?

Many thanks,

Ian

Ian,
I'm attaching a small web page that uses our Play and Convert multimedia controls v15 to perform simple playback and conversion.

There are two additional things you will need to do for the web page to run on a machine that does not have LEADTOOLS Multimedia installed:

1) You will need to create a signed CAB file and reference it in a CODEBASE parameter for each object. For a list of files to include in the CAB, refer to the Files to be included with your application in the Multimedia documentation.

2) Because the LEADTOOLS Multimedia control is licensed, you must create an LPK file using Microsoft's LPK_TOOL.EXE (Available in the ActiveX SDK from Microsoft at http://www.microsoft.com/intdev/default.htm). This helps generate an encrypted LPK file containing all of the license strings that are required by your script's controls. This allows the use of the ActiveX and certain features in web pages, without putting the license keys in the web page. Microsoft's Internet Explorer only honors one LPK file per page, so you should generate a LPK file including license strings for every control that you intend to use. You should then insert the following into your HTML before the licnesed controls are created:

Hi Gabriel,

What was it that should be inserted into the code before the controls are created? Nothing appeared.

Happy new year...

Iain...

Iain,
The first step is to get it working where LEADTOOLS is installed (the development machine). If that works, the second step you need is to test it on other computers (deployment machines).

Which one of these 2 steps is failing?

Also, are you using the Evaluation edition of LEADTOOLS multimedia (ltmm15_E.dll) or the Release edition (ltmm15_N.dll)?
If you are using the evaluation edition, you need to change the classid values in the HTML file as follows:

For the ltmmPlayCtrl object, instead of:
00150926-B1BA-11CE-ABC6-F5B2E79D9E3F
Use:
00150A26-B1BA-11CE-ABC6-F5B2E79D9E3F

For the ltmmConvertCtrl object, instead of:
00150920-B1BA-11CE-ABC6-F5B2E79D9E3F
Use:
00150A20-B1BA-11CE-ABC6-F5B2E79D9E3F
