WMV media streams appear more pixelated on Windows 7 than on XP

由 混江龙づ霸主 提交于 2019-12-08 08:24:40
问题 Our streaming media player is an in house C++/DirectShow application and runs on XP and greater. One of our most widely used streaming codecs is WMV, as it's widely supported. We've noticed that output from WMV media streams looks different on Windows 7 clients than on Windows XP. Windows 7 output looks much more pixelated / blocky for WMV streams. An identical stream (coming from a media server) on Windows XP appears much smoother / less pixelated. The same playback graph is used on both

I have a directory of bitmaps that are all of the same dimension. I would like to convert these bitmaps into a video file. I don't care if the video file (codec) is wmv or avi.

I have read a few things about using the Windows Media SDK or DirectShow, but none of them are that explicit about providing code samples.
