Also install “tools” to get the utility gst-inspect-1.0 for examining the GStreamer installation.If you intend to modify the code, use a separate “build” directory: replace “cmake [ ] .” by “mkdir build ; cd build ; cmake [ ] ..”; you can then clean the build directory with “rm -rf build/*” (run from within the UxPlay source directory) without affecting the source directories which contain your modifications.
The above script installs the executable file “uxplay” to /usr/local/bin, (and installs a manpage to somewhere like /usr/local/share/man/man1 and README files to somewhere like /usr/local/share/doc/uxplay). It can also be found in the build directory after the build processs.
