Emulator

I have the same problem on Debian Wheezy (Linux AMD64).

The only common factor I can think of is that both Debian and Ubuntu have moved to the libav fork of ffmpeg. (At least I think so). Does my patch fix it for either of you?

For this compiles, but not linkes (linux ubuntu 12.04).
../VideoCommon/libvideocommon.a(AVIDump.cpp.o): In function AVIDump::AddFrame(unsigned char*, int, int)': AVIDump.cpp:(.text+0xef): undefined reference to av_rescale_q(long, AVRational, AVRational)'
collect2: ld returned 1 exit status

Solved with the patch.

I wonder if I should report a bug against libav in Debian even though the upstream fix is simple. As this compiles against the ffmpeg in OpenSUSE 12.1 and the older ffmpeg in Debian 6.

Glad the fix works, I am not much of a coder so I had to dig around searching for avutils stuff. :P Thanks for testing it.

Issue 5273 has been merged into this issue.

Is there any reason not to apply this patch immediately? libavutil/mathematics.h has been present in ffmpeg (and consequently now libav) since time eternal, so I don't see that it would break builds on systems not using libav:

http://git.videolan.org/?p=ffmpeg.git;a=history;f=libavutil/mathematics.h;h=93314bae16a08a8d7ea492481be9bd4869f7a99d;hb=HEAD

What version of libav do you have? With the version of libav that I have mathematics.h is included by libavutil.h, and that is included by libavcodec.h. So the inclusion is redundant.

Ffmpeg/libav in Wheezy is currently: 0.8-2. http://packages.debian.org/wheezy/ffmpeg

where is the patch you guys mentioned? i got the latest source from git and i am experiencing the error:

../VideoCommon/libvideocommon.a(AVIDump.cpp.o): In function AVIDump::AddFrame(unsigned char*, int, int)': AVIDump.cpp:(.text+0xef): undefined reference to av_rescale_q(long, AVRational, AVRational)'

make[2]: *** [Binaries/dolphin-emu] Error 1
make[1]: *** [Source/Core/DolphinWX/CMakeFiles/dolphin-emu.dir/all] Error 2
make: *** [all] Error 2

i would imangine a patch from march would be part of the full source now, right?

seriously guys help me, or tell me how to disable libav support.

It's also not working for me I'm on ubuntu 12.04 64bit

eunb, we know it doesn't compile. If you want it to compile, go follow the instructions on Issue 5392.
