That would be me (yes still lurking on this list). I've got the patch and it looks good. So I'll apply it. One question though, is this a compressed format? IOW is the bandwidth usage lower then with raw YUV420 ? I want to know because of how libv4l selects the source format. As you said in your patch submission you've put this above raw bayer, as it should be prefered over raw bayer. And thats fine by me. But if the cam can also do JPEG, libv4l will prefer jpeg over this, as that has the compressed flag set in the format listing and for resultions > 176 x 144 it will prefered compressed formats (to get decent framerates on usb1 connections). So if this compressed to, the compressed flag should be set in the format table in libv4lconvert.c Regards, Hans --~--~---------~--~----~------------~-------~--~----~ Lets make microdia webcams plug'n play, (currently plug'n pray) To post to this group, send email to [email protected] Visit us online https://groups.google.com/group/microdia -~----------~----~----~----~------~----~------~--~---
