Encode WMV at highest possible speed heinz_mueller_1970[ at ]yahoo.de 6/25/2007 10:11:33 AM Hi *, Is it in general possible to bypass the internal timer in IWMWriter, so that one can encode video in WMV format at highest possible speed? My problem is that I do have some video streams which last several hours and if I try to compress them as WMV while the internal timer is enabled, this operation will take too long. I need to do that recompression as fast as possible. Of course I can provide the encoder with original timestamps for the samples. Thanks in advance for any tips! heinz

Unless you did something to force the WMWriter object to work in real time, the WMWriter just works as fast as possible. AFAIK, the only way to make the WMWriter object work in real time is to add a sink that works in real time and the default file sink shouldn't require real time. You should consider that WMV compression is very CPU-intensive and it may barely make it in real time on a powerful machine and run significantly slower than that on a low-end one. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
