Now my question is, if uvcvideo driver would do some MJPEG->YUV conversion, would it be possible to make my camera work in other or atleast applications? I could try to experiment with this stuff myself tooif someone would point me to the correct direction.
It appears there is http://www.linuxtv.org/v4lwiki/index.php/ V4L2UserspaceLibrary project that would do MJPEG->YUV conversion in userspace if any, I do admit that doing it in the driver would be stupid. However it looks like there is also the gstfakevideo that can do the conversion using gstreamer since V4L2 solution is not quite ready yet. However in the case of SiGma Micro it fails as well.
I also assume that SiGma Micro is even actively developed since r211patch is SiGma specific and r212 frameintervals fix also fixed the thing on SiGma, thanks for that. :) If there's anything I can do, let me know.
I just realized after reading mailing lists that before that patch it wasn't on the supported list at all. And I am not sure if it should be there quite yet. As mentioned the camera works with luvcview, but that is the only application it works with. I can't use gstfakevideo, because gstreamer gives the error message Lorenzo Battistini already mentioned:
Failed querying control 9963788 on device '/dev/video0'. (5 - Input/ output error)
Ekiga, mplayer, etc. all fail as well. On both Windows and Mac OS X the camera works like a charm. If anyone has any ideas where the problem is, I would be happy to hear them. Meanwhile I will try to research myself and will keep posting possible updates here. Getting the gstfakevideo would already be enough, because I believe it will fix all the applications with its YUV conversion...
