wmvcopy and seek visuall 5/30/2007 7:54:01 AM Hello, I have an application similar to wmvcopy. It records ( copies ) wmv streams ( local and online ) to a custom sink. The samples are then written to a custom sink using the wmv writer. So far so good. Now I want to add seek support so the record can start at arbitrary position in source and also the position can be changed while copying. Making the reader seek is not a problem at all. The problem comes when I pass the samples to the wm writer. Because of the messed timestamps the writestreamsample method hangs. It hangs even if I start reading from middle and pass the first sample to it. Ideas how I can solve the problem? Regards, -- Nick Kichukov, project manager, eConsulting LLC

Also, if you are copying compressed samples, either seek to a clean point or mark the samples as discontinuities until the next clean point. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
