hi,
i try to build on linux with mingw64 toolchain the gstreamer packages.
all build and working fine except gst-ffmpeg. gst-ffmpeg inlude
libav as
it's backend. when i try build it on linux with mingw than i use yasm.
it compile and build without any kind of error, but when i try to
use it
seg fault immediately.
The backtrace isn't much meaningful, please get gdb to point the
sources. We have mingw64 builds on win32.libav.org could you please try
those and see if ffplay can decode correctly your testfile?
qlist -Iv yasm mingw
cross-i686-w64-mingw32/binutils-2.21
cross-i686-w64-mingw32/gcc-4.5.2
cross-i686-w64-mingw32/mingw64-runtime-20101003
cross-mingw32/binutils-2.21
cross-mingw32/gcc-4.5.2
cross-mingw32/mingw-runtime-3.18
cross-mingw32/w32api-3.15
cross-x86_64-w64-mingw32/binutils-2.21
cross-x86_64-w64-mingw32/gcc-4.5.2
cross-x86_64-w64-mingw32/mingw64-runtime-20101003
dev-lang/yasm-1.1.0-r1
Those are my versions for the toolchains not sure how much it helps.
not too much.
now i try to build a standalone libav. here are a few of my thoughts:
- it'd be good if configure can except (or ext least don't generate
error on default arguments like:
--host=i686-w64-mingw32
--exec-prefix=/usr/i686-w64-mingw32/sys-root/mingw
etc.
If you are referring to yasm you are supposed to have it installed, it
is optional-only-if-you-accept-detriment, if you are referring to
windows-specific hacks, we are still hoping the next iteration could fix it.
- it has no real reason to generate symlink in case of cross compile,
since on windows it's not working:
avcodec-53.dll -> avcodec-53.5.0.dll
but in this case may be name it avcodec-53.dll would be better then
avcodec-53.5.0.dll otherwise the exe can't find the dlls.
That should be fixed in the current libav git.
i'm still trying to make a working version...
I hope you'll manage to get one soon.
