Whenever I set a start and end point in the Source Properties dialog box, the target file is all messed up. A problem occur: the target starts at my selected start point then continues to the end of the source clip (won't recognize my selected end point).I use the put_SelectionEnd() to set the end point, but it does not have effect!!! I need you help.thanks    Report

[LEADTOOLS Multimedia15\Examples\Ltmm\Cpp\Convert]. 2- Add the following code before calling the m_convert->StartConvert(). //// hr = m_convert->put_SelectionStart(2.0); hr = m_convert->put_SelectionEnd(3.0); //// 3- Run the demo. 4- Select one of the LEADTOOLS Media videos shipped with the toolkit such as "DaDa_CMP.avi" file 5- Select your desired output format. 6- Start the conversion. You will get an output file with 1 second length. Adnan Ismail LEADTOOLS Technical Support    Report

The video total duration comes wrong. ltmmConvert.SelectionStart = 30.0; ltmmConvert.SelectionEnd = 31.0; ltmmConvert.StartConvert(); The source videos total duration is 5 min (5:00) and the converted video segments total length comes to be 4 min and 30 sec (4:30). Unable to understand at all!    Report

If not, please try to do that. Also, can you tell me what build number (version info) of our Multimedia LTMM*.DLL you have on your computer? Adnan Ismail LEADTOOLS Technical Support    Report

Considering the following lines of code, One thing that I observed is : ltmmConvert.SelectionStart = 2.0; ltmmConvert.SelectionEnd = 7.0; ltmmConvert.StartConvert(); When the source is .avi the converted .mpeg file is of 5 sec duration. When the source is .mpeg the converted .avi file is of 5 sec duration. But when the source is .mkv the converted .avi file is of 56 sec duration And converting it to .mpeg raises exception and code exits. WHY? According to my understanding the captured portion of converted file should be of 5 secs starting from the second sec to the seventh sec of the source. The version of  LTMM15.DLL is 15.1.0.025    Report
