Hi to all,
for a project, I'd like to bundle ffmpeg statically. The project itself
is cross-platform, which is proving to be a challenge.
For this, I'd like to build ffmpeg statically and link in libx264 and
libx265 so that I only have to link my library in turn to ffmpeg and be
done with it. I started to experiment with this on Linux. In order to
achieve that, I compiled both libx264 and libx265 statically with
--enable-pic (my distro only ships static libs with -fPIE :( ).
I then build ffmpeg with the following flags:
$ ./configure --prefix=/tmp/master-x264-x265-minimal --enable-static
--enable-pic --disable-everything --disable-programs --enable-libx264
--enable-libx265 --enable-gpl
When running "make V=1" and inspecting the gcc calls, I can however not
see where both libx26* are linked into ffmpeg. I also inspected
libavcodec, but couldn't find any (undefined) symbols of h264 or h265. I
only saw
$ nm *.a | egrep -i "(264|hevc)"
U ff_h264_profiles
U ff_hevc_profiles
0000000000000340 D ff_h264_profiles
00000000000002e0 D ff_hevc_profiles
...
The pkgconfig files generated however contain direct references to
"-lx26?". Excuse me if I am overseeing something obvious. I tried this
with master from 10minutes ago and 3.0.2
So my question is, how can I link x264 and x265 into libavcodec so that
symbols/objects from these dependencies are imported into libav*
completely?
Best,
Peter
