Pls ignore the stuff about missing locale settings. I think it has something to do with ffmpeg. This mode doesn’t work well (dependencies are not tracked properly in CMake scripts due lack of “pkg-config” support).When i try to make tvheadend on raspbian (raspberry pi). This build produces libraries for static linkage with ffmpeg, so all ffmpeg’s dependencies are required. You’ll need to specify the ffmpeg library locations explicitly when you configure and build ffmpeg. If you are building ffmeg, the default library install locations are not very smart. I can find libopen264.so.6 under the ~/anaconda3/envs/p圓8/lib/ (p圓8 is my conda virtual environment), but we only need an older version libopen264.so.5. The root cause is that libopen264.so from python 3.8 is too new for ffmpeg 4.2.2. Include the log file “config.log” produced by configure as this will help solve the problem. If the latest version fails, report the problem to the mailing list or IRC #ffmpeg on. What to do if the latest version of FFmpeg fails? In a typical install scenario, these files would be located at /usr/lib/pkgconfig. libavcodec.pc, libavdevice.pc, etc.) that tell it where the FFMPEG headers and libraries are located. Where is the pkg config file for FFmpeg?Īpparently, CMake is unable to find the pkg-config files for FFMPEG (i.e. Apparently, CMake is unable to find the pkg-config files for FFMPEG (i.e.
#FFMPEG LINUX COMPILE HOW TO#
I figured out how to fix my problem, and trying to point CMake at the appropriate install location isn’t the issue. How to compile an OpenCV program into Linux?Īssuming that you have saved your first OpenCV program as image-conversion.c you can compile your program with the following linux command: $ g++ `pkg-config opencv –cflags –libs` image-conversion.c -o image-conversion After successful compilation a new executable binary file named image-conversion is created in your current working directory. Video is captured in opencv by VideoCapture cap.open (“UDP://127.0.0.1:5000”). Video is coded by the H264 codec and send to localhost UDP. Video capture is done by FFmpeg from Windows. Linux has installed FFmpeg, GStreamer and opencv build from source with support of both mentioned.
#FFMPEG LINUX COMPILE MAC#
OpencCV is a multi-platform library, but this article will be focused only on OpenCV using Linux operating system (although, just the installation of the OpenCV library and video camera is platform-specific, all examples in this article should compile on any platform where OpenCV is properly installed such as Mac OS, MS Windows and etc.). Is the openccv video camera compatible with Linux?
How does OpenCV web camera work in Windows? The opencv cmake should then be able to find the ffmpeg libraries. `./configure –prefix=/usr –libdir=/usr/lib64 –pkgconfigdir=/usr/lib64/pkgconfig –incdir=/usr/include will result in ffmpeg ‘s make install putting the ffmpeg libraries in a location where pkgconfig can find them.
