x264-go provides H.264/MPEG-4 AVC codec encoder based onx264 library.
C source code is included in package. If you want to use external shared/static library (i.e. built with asm and/or OpenCL) use-tags extlib
go get -u github.com/gen2brain/x264-goextlib- use external x264 librarypkgconfig- enable pkg-config (used with extlib)
