@section Intel QuickSync Video
Libav can use Intel QuickSync Video (QSV) for accelerated encoding and decoding
of multiple codecs. To use QSV, Libav must be linked against the @code
{
libmfx
}
dispatcher, which loads the actual decoding libraries.
The dispatcher is open source and can be downloaded from
@url
{
https://github.com/lu-zero/mfx
_
dispatch.git
}
. Libav needs to be configured
with the @code
{
--enable-libmfx
}
option and @code
{
pkg-config
}
needs to be able to
locate the dispatcher's @code
{
.pc
}
files.
