Hi, Earlier versions of guvcview where compatible with gtk+ 2.8, but since 2.10 was already around I set that for configurion, but a lot has changed since :-) Most distributions keep the gtk+ library up to date, so this was never a problem before. Anyway, I will fix it ASAP.
PS: mjpeg compression code is available in svn if you want to test it. When streaming in MJPEG (or JPEG as is the case of some gspca cameras) there will be a spin box with the quality factor in the video controls and a Apply button. In my case there was absolutly no difference in frame sizes in any of the tested values, I still need to verify the quantization tables for all of the cases, if they are the same then compression is unchanged. The quality factor seems to change only to a couple of values: Q=20, 40, 60, 80 and 100 Best regards, Paulo 2009/6/3 Jon Fairbairn <[email protected]> > Further to your test of mjpeg compression, (on the uvc.devel > mailing list) I thought I'd try guvcview with my camera. > Unfortunately it doesn't build on Fedora 9 > > .../src/video_tab.c:366: undefined reference to > `gtk_dialog_get_content_area' > > Apparently gtk_dialog_get_content_area only appeared in gtk+ in > version 2.14, but the Fedora 9 gtk+ is 2.12, so I'll either have > to wait until I upgrade the OS or install a newer version of > gtk2 somewhere out of the way. > > However, your configure.in says "gtk+-2.0 >= 2.10.0" but I > reckon it should say 2.14.0. > > Cheers, > > Jón > > -- > Jón Fairbairn [email protected] > 31 Chalmers Road [email protected] > Cambridge CB1 3SZ +44 1223 570179 (after 14:00 only, please!) >
