+This is patch for live555 library, latest version (when this patch has created) 2007.11.18 from http://live555.com/liveMedia/public/
+
+This patch provide the support in the JPEG RTP stream of the image dimensions - width and height - to have value more than 2040 (it's limitation of RTP JPEG standard), if a SDP stream description have a field "a=x-dimensions:width,height"
+
+To apply it, download archive with the "live555" library, copy a file "jpeg_dimensions.patch" to the root directory with the sources, and run
+patch -N -p0 < jpeg_dimensions.patch

jpeg_dimensions.patch
