If Python is not available, you will need to supply the correct CFLAGS and LDFLAGS manually prior to running configure so that it is able to detect ffmpeg libraries.įor example, if ffmpeg was built with x264 and mp3 encoder support, you will need to pass additional " -lx264 -lmp3lame" flags when linking libavformat. You need to have Python installed to run this script of course, and the configure script detects its availability automatically. The pkg-config is not installed by default on Mac, as the output above shows, hence we use the alternate pkgconfig.py script. The pkg-config tool is used to detect the correct compilation settings and library dependency for the ffmpeg packages. Note that for this particular build, alternative locations (prefixes) are specified for both SDL and ffmpeg with -with-sdl and -with-ffmpeg options respectively. It also found OpenH264, libyuv, and ffmpeg packages (libavformat, libavcodec, etc). The above output shows the SDL version detected, 2.0.1 in this case. libavformat libavcodec libswscale libavutil python pkgconfig.pyĬhecking ffmpeg packages. Users/pjsip/Desktop/optĬhecking for python. Pay attention to the following output (the sample below was taken on a Mac): Video requirements will be detected by the configure script. To change the default CFLAGS, we can use the usual "./configure CFLAGS='-g'" construct. The default settings build the libraries in "release" mode, with default CFLAGS set to "-O2". Run "./configure" without any options to let the script detect the appropriate settings for the host: Mingw-w64 is supported since 2.11, including video with DirectShow? camera, please check here for more info. More over, cross-compilations might also work with Cygwin using this build system. Ffmpeg build alsa windows#FreeBSD (must use gmake instead of make)īuilding Win32 applications with Cygwin is currently not supported by the autoconf script (there are some conflicts with Windows headers), but one can still use the old configure script by calling.The build system is known to work on the following hosts: without this you can still enjoy video with pjsua console application.Optional: Qt development SDK for building the video GUI sample.Linux: Video4Linux2 (v4l2) development library.
