<div dir="ltr">Hi, I'm working on a project where I need to get H264 encoded video from a Logitech C920. As I understand it I need to use uvch264 for this, as v4l2src is not able to get H264 encoded video from a C920. (This is based on a few discussions I've found online and the fact that a basic pipeline like "gst-launch-1.0 v4l2src ! video/x-h264 ! fakesink" doesn't work.) The stable 1.0.8 release of gst-plugins-bad doesn't have uvch264 ported yet, so I've tried to install the 1.1.2 developer release which does. Unfortunately, this is what I get regarding uvch264 when I try to "./configure" the bad plugins: configure: *** checking feature: UVC H264 *** configure: *** for plug-ins: uvch264 *** checking linux/uvcvideo.h usability... yes checking linux/uvcvideo.h presence... yes checking for linux/uvcvideo.h... yes checking for GST_VIDEO... yes checking for G_UDEV... no checking for LIBUSB... no configure: *** These plugins will not be built: uvch264 I'm pretty new to all this GStreamer stuff, so excuse my ignorance, but to try and resolve the missing "G_UDEV" and "LIBUSB" dependencies I installed the following packages (I am using Ubuntu 13.04) with these commands: "sudo apt-get install libgudev1.0-cil-dev" "sudo apt-get install libusb-dev" But I get the same results, "checking for G_UDEV..." and "checking for LIBUSB..." still both say "no". Even worse, with this 1.1.2 build of GStreamer I can't use v4l2src to get another video format from the camera. The "gst-inspect-1.0 -b" command shows "libgstvideo4linux2.so" as blacklisted. So I'm giving up on this for tonight. --- Basically, my question is this: Assuming there isn't some way of getting v4l2src (from a stable release) to stream the H264 encoded video from my C920, can anyone help me get the right dependencies so that uvch264 will install?</div>
