Seem amsn now use libng from the xawtv package you need to add a converter for the MJPEG palette and uncomment the YUYV converter (untested) set in the libng package (I am looking at the CVS code). You can get the MJPEG converter from uvcview in the utils.c file. > Also, you say it supports YUYV, am i not correct in assuming the output of > the driver is in either format, MJPEG or YUYV? i thought i saw something of > the sort in uvcview, although i am not certain what it was. assuming it > does. then why cannot the program access it correctly, and if it cant..well > i guess i have to figure out how to add it. uvcview in YUYV grab the stream and forward to the display in MJPEG add the missing Huffman table, decompress the jpeg picture to YUYV and forward to the display. > Also, heh, i have snooped around the amsn project pages, but they dont have > any mailing list to send requests to, and lol have not figured out how to > on SF.com so hmm. #amsn on irc.freenode.net http://amsn.sourceforge.net/forums/viewforum.php?f=8&sid=0f2fc183f3ae3a339d4ad056868dbebd > On 1/26/06, Laurent Pinchart <lau...@sk...> wrote: > > Hi Tanner, > > > > > Hmm, ill look into gnomemeeting (its emering now). however my primary > > > interest is aMSN and its msn (obviously heh) webcam. > > > The application supports v4l (v4l2?) and can even see my device, listed > > > > as > > > > > 'V4L-2: ', and when clicked on, displays a 'Error getting capabilities' > > > message. once engaged in the conversation the light on my camera will > > > start, but it never seems to be working. > > > > After a quick look at the source code, aMSN seems to support V4L2 and > > YUYV but > > not MJPEG.
