ffmpeg4 (Software to record, convert and stream audio and video).
|
|
|
|
|
|
|
|
|
|
ffmpeg4 should be installable alongside ffmpeg 3.x without conflict.
|
|
|
|
|
|
|
|
|
|
FFmpeg is a complete solution to record, convert and stream audio
|
|
|
|
|
and video. It includes libavcodec, the leading audio/video codec
|
|
|
|
|
library.
|
|
|
|
|
|
|
|
|
|
By default it will not build the ffmpeg binaries or man-pages, in order
|
|
|
|
|
not to conflict with an ffmpeg 3.x package. You can change this by
|
|
|
|
|
using the following environment variable setting:
|
|
|
|
|
|
|
|
|
|
BINS=yes
|
|
|
|
|
|
|
|
|
|
It can optionally link to a number of extra libraries that are available
|
|
|
|
|
on SBo by setting the relevant env vars, which all default to "no":
|
|

By default, ffmpeg4 is built to link with openssl. This creates a non-
|
|
|
|
|
redistributable binary (just like linking with libfdk-aac does). If you
|
|
|
|
|
want a redistributable binary you can change from linking with openssl
|
|
|
|
|
to linking with gnutls instead by setting:
|
|
|
|
|
|
|
|
|
|
OPENSSL=no
|
|
|
|
|
GNUTLS=yes
|
|
|
|
|
|
|
|
|
|
Both of these libraries are available in Slackware itself.
|
|
|
|
|
|
|
|
|
|
There are a few other libraries available in Slackware that are also
|
|
|
|
|
linked to by default, and you can disable them by changing the default
|
|
|
|
|
of "yes" to "no" with the following settings:
|
|
|
|
|
|
|
|
|
|
LIBCACA=no
|
|
|
|
|
LIBCDIO=no
|
|
|
|
|
LIBFONTCONFIG=no
|
|
|
|
|
LIBFREETYPE=no
|
|
|
|
|
LIBFRIBIDI=no
|
|
|
|
|
LIBOPENJPEG=no
|
|
|
|
|
LIBPULSE=no
|
|
|
|
|
LIBSMBCLIENT=no
|
|
|
|
|
LIBSSH=no
|
|
|
|
|
LIBTHEORA=no
|
|
|
|
|
LIBV4L2=no
|
|
|
|
|
LIBVORBIS=no
|
|
|
|
|
LIBVPX=no
|
|
|
|
|
LIBWAVPACK=no
|
|
|
|
|
OPENGL=no
|
|
|
|
|
|
|
|
|
|
To link to this version of the ffmpeg libraries, you'll need to set
|
|
|
|
|
the PKG_CONFIG_PATH to "/usr/lib${LIBDIRSUFFIX}/ffmpeg4/pkgconfig"
|
|
|
|
|
where ${LIBDIRSUFFIX} is either 64 or an empty string, depending on
|
|
|
|
|
your architecture.
