DirectShow Theora Issue with RGB24
...ph 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? Unfortuntatly I need to stick with RGB as I have already written a significant amount of code around this. Should I not be using RGB24 as an input to the OGG Mux filter? If not, can anyone suggest a good (free) Colour Space Convertor to conver...

Directshow filters 0.64.7878
Updated again... theora works and seeks properly (not to keyframe) in WMP 9 and 10. You can encode from a bunch of onew input types like RGB32, RGB24, IYUV etc. And fixed a bug that was stopping the filters being used in a activeX control in an IE browser. www.illiminable.com/ogg/ Enjoy, Zen.

Problems with Theora DirectShow filters
...encode it with the Theora and Speex DirectShow-filters. For audio, this filter graph plays fine: http://www.huitl.de/mic-speexenc-speexdec-out.png. The video part is problematic. Please have a look at http://www.huitl.de/cam-theoraenc-theoradec-out.png. 1. The webcam provides the color formats RGB24, I420 and IYUV. The Theora encode filter only accepts YV12, so I can't just connect the webcam capture pin with theora's yv12-in. 2. The "Color Space Converter" can't do the conversion to YV12. 3. I found that the ffdshow raw video filter should be able to do this conversi...

...n alpha channel, and if there is, where and how it's represented, and perhaps something to accurately specify the colour space, basically what you are doing is opening up millions of possibilities, most of which are completely useless. If you have a bits per channel field in RGB, what about RGB24, 3 channels, 8 bits each, but padded into 32 bits. RGB555, 15 bits, padded to 16. There's thousands of invalid possibilities, and only 15-20 or less valid ones... only really 3-5 commonly used. If someone wants to go crazy and design a franken-yuv format for some bizarre reason, then they...

encoding image from a webcam
...k locally so we don't care about the transmission. This is what I've understood till now: I have a char * buffer from the camera RG24,I convert it to YCbCr 4:4:4, I encode it, resulting an ogg_packet. Then I provide this ogg_packet to the decoder, get the YCbCr buffer , convert it back to RGB24 then display it. Now the questions: I have a Codec class with a function encoderInitialize(), where I initialize the encoder, filling a th_info structure with the image's properties, fps, aspect ratio, colorspace, quality and pixel_fmt. Then I allocate a th_enc_ctx handle and repeatedly call...
