VLC media player is a free and open source media player and multi- media framework written by the VideoLAN project. VLC is a portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as DVDs, VCDs, and various streaming protocols. It is able to stream over networks and to transcode multimedia files and save them into various formats. This build aims to support as many options as possible using the SlackBuilds listed in the REQUIRES field of the vlc.info file. No script changes are necessary to include particular options; if they are detected at build time, they will be included. Conversely if optional packages are not available at build time, vlc will generally continue to build with a reduced feature set. Support for OpenCV is temporarily disabled by default due to build error. However it is possible to include opencv support using the somewhat older opencv-legacy SlackBuild rather than opencv. It then needs to be explicitly enabled by setting the the OPENCV environment variable to "yes" e.g. OPENCV=yes sh vlc.SlackBuild This requires the opencv-legacy package to be installed at build time. Support for Wayland is a special case. It is not supported by default but can be enabled setting the WAYLAND environment variable to "yes" when running the SlackBuild e.g. WAYLAND=yes sh vlc.SlackBuild This support also requires additional SBo packages wayland-egl and wayland-protocols. It also depends on the qt5 package having been built with wayland support i.e. wayland package was installed when the qt5 package was built. The vsxu SlackBuild is now optional for x86 machines; removed from REQUIRES since it does not compile on arm machines at the moment. Please advise the maintainer to suggest support for any further options. *NOTES* - the qt4 interface seems not to be working ATM so the qt5 one is enabled by default: this means qt5 is a new mandatory dependency - you *need* to version-bump the libva and libva-intel-driver in Slackware to versions 1.7.3 for VAAPI support: as we suppose a standard install, "--enable-libva=no" is added between the configure options, instead
