Emulator

Dolphin works excellently in fedora 17 64bit, but in fedora 18 beta it is not; I've been compiling dolphin emu for a month every 3-4 days; thought it was something to do with commits. but when I saw dolphin emu working fine in fedora 18 i686 (x86), i'm submitting this issue here.

Is this a bug in Fedora 18 x64?

Don't know, but the "Warning: of using wii mote" is not shown, like in this video first 1-2 seconds; http://www.youtube.com/watch?v=mK4T9KnOLhY; or this image: http://2.bp.blogspot.com/-HGxeju5IzZQ/ThKm4FS9iwI/AAAAAAAAAO4/I7IIKwZr294/s1600/dolphin1.png

I hope that will give a clue on which package is missing or incompatible. Thanks.

Issue 5765 has been merged into this issue.

I was noticing reports in earlier version of fedora of packages not being in sync between i686 and x86_64 repositories. I've checked the basic devel packages needing install to compile, and they all seem to match up.

I'm assuming the more information the better

In case stating helps, I've been having this problem for a few months with Gentoo amd64.

I finally found the cause of this issue (after compiling 10 billion times :P). It's caused by ffmpeg/libav. I'm still trying to figure out how to fix it, but a temporary workaround is attached. Note that the AVI dump feature will no longer work.

chenxiao,

Thank you, now it works in fedora 18 x86_64

Hmm...I'm not sure what the cause of the issue is. No matter what FFmpeg I compile against, the black screen issue always occurs. I've tried compiling against the following FFmpeg versions:

• Fedora 17 SRPM recompiled on Fedora 18
• Fedora 17 binaries on Fedora 18
• Manually compiled ffmpeg 0.10.6
• Manually compiled ffmpeg 1.0.1
• Manually compiled ffmpeg from git
• Manually compiled libav from git
• Arch Linux binaries on Fedora 18

I can compile against any of the FFmpeg versions above on another distro and then run it on Fedora 18 and it will work just fine.

To dolphin-emu developers:

Please merge the following patch. It's needed to compile against FFmpeg libraries in another prefix (ie. not in /usr). It just takes the path from the pkgconfig.

With the last build it's no work. Order solution ?

On Mageia x64 my screen is also black.

Is this bug also affected to non nvidia gpus?

btw: dumping a good frame by apitrace and replay on the affected system displays correctly.

Does this patch also solve the issue?

yes thx :)

@ chenxiao and AsifAliRizvan:
As I don't touch libav at all, I'm not sure we are talking about the same bug, so can one of you please confirm my patch?

@wikermarkus

Yes, your patch solved the black screen issue on fedora 18 x86_64.
ffmpeg was not touched in anyway.

Thank you!
