...trying to capture video and audio from a webcam in order to 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 ffd...

...ter correcting the base SDK in each Xcode project (they're all set to the OS 10.4 SDK, which is not surprisingly missing on an up-to-date system), populating the header-search paths in the various projects (which were blank), and building FLAC, I'm stuck at "library not found" for theoradec. I went into the theora directory and ran autogen.sh, but as far as I can tell it didn't generate the lib. The Theora Xcode project did compile and create the Theora framework, however. Anyone have hints or steps for building the XiphQT components? Thanks!

What is the PostProcessingLevel field of PB_INSTANCE? When is it used? It is used for all Theora's video or it is just for legacy support with VP3? Thanks -- Leonardo de Paula Rosa Piga Undergraduate Computer Engineering Student LSC - IC - UNICAMP http://www.students.ic.unicamp.br/~ra033956

...framework from Gstreamer's Queue element. A leaky queue drops buffers if it fills up, rather than blocking entirely. By making the queue of undecoded video buffers leaky, we can ensure that audio continues to play correctly even when there is not enough CPU for video. Intriguingly, jst's TheoraDec element was already correctly wired to notice the discontinuity introduced by a dropped buffer and skip all frames until the next keyframe. What: The effect of this patch is approximately to make Cortado fall back to keyframe-only decode when it runs out of CPU. Where: I tested the modified code...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The attached patch splits Theora decode and YUV2RGB into separate threads. These are by far the two most computationally demanding components of Cortado, so by splitting them we can substantially improve performance on multiprocessor machines. I have verified that the patch does split these into two threads, and performance does appear to improve.
