Media Foundation MFTransform to convert MFSample from 'MJPG' to 'YUY2' or 'RGB24'

问题 Do anyone know what MFTransform should I use to convert a 'MJPG' MFSample to 'YUY2' or 'RGB24'? Any tip will be very appreciated. Thanks 回答1: Since the number of visits to this post was noticeable I'm going to answer my own question. The trick is to enum all the transformations between MJPG and YUY2 since it seems there isn't direct transformation between MJPG and RGB32. To transform the image between YUY2 and RBG32 use the color converter DSP: http://msdn.microsoft.com/en-us/library/windows

问题 I'm hoping to record some audio and then have the ability to play it back. Its important for me to be able to customize the record interface.

View print CSS in IE7 or IE8

由 删除回忆录丶 提交于 2019-12-08 18:01:56
问题 I'm debugging a site that has problems with element positioning when printing (I have a separate print.css file linked by a link element with the media="print" attribute). This problem only occurs in IE7 and IE8. What I'm looking for is a way to view the page using the print media type, but while still having IE8's developer tools available to view element details and edit in real-time, etc. The function I'm looking for would be similar to the "Display CSS by Media Type" feature in Chris
