If you don't mind using Gtk (2.0 or 1.2 + gdk-pixbuf), you use the GdkPixbuf library to make your life easy. Other pointers are libjpeg (see xawtv for sample code, also included in libjpeg itself). mjpegtools has a mmx/sse/2dnow optimized libjpeg with a single jpeg_encode/decode function (takes YUV420 planar frames) to make your life easy. And last, there also (tadadada, you should know this since you're from ridgerun ;-) ) gstreamer, which can also do this like 'v4lsrc ! jpegenc/jpegmmxenc ! filesink'. > It would be great if I could locate an existing v4l2 > codec driver which has the logic for producing jpegs. > That would be super, but any pointers would be great. The zoran driver which I'm currently working on has hardware JPEG encoding support. It works in v4l1 (see mjpegtools' lavrec), and I'm currently working on the v4l2 driver, which isn't finished yet.
