<div>Hi,</div>
<div> </div>
<div>I hope you can help, I am in need of some assistance with the DirectShow filters for Theora. </div>
<div> </div>
<div>I have successfully created a working capture graph using OGG / Vorbis / Theora, however, when I add a Sample Grabber Directshow filter between the FFDShow decoder and Theora Encoder, this results in the video file being mirrored vertically. I have noticed that the original CaptureGraph was using YUV12, but the SampleGrabber is configured to use RGB24. Is it likely that this is the cause of the problem? </div>
<div> </div>
<div>Unfortuntatly I need to stick with RGB as I have already written a significant amount of code around this.</div>
<div> </div>
<div>Should I not be using RGB24 as an input to the OGG Mux filter?</div>
<div>If not, can anyone suggest a good (free) Colour Space Convertor to convert from RGB24 -> YUV12 (The Microsoft only seems to convert between different RGB formats)</div>
<div> </div>
<div>Many thanks,</div>
<div>Steve.</div>
