Tag: ffmpeg_integration
dsputil_mmi.c idct_mmi.c mmi.h mpegvideo_mmi.c
Log Message:
Start working on a branch where FFmpeg is not copied, patched and carved to be
built with automake but instead imported inline and built using its own build
system. This is an import of a slightly modified FFmpeg current tree. xine-lib
builds, install and run fine with it, but there are of course plenty of things
that needs to be fixed before it can even be considered for a 1.2.x series.
Work will continue in the next days of course.
