ffmpeg error smoperand has impossible constraints Leoti, Kansas

So I run some test builds Fedora 18 (gcc 4.7.2): build ok Fedora 20 (gcc 4.8.3): same error, fixed by the proposed patch [2015-08-02 07:31 UTC] [email protected] Automatic comment on behalf my guess from looking at your code was that its looking for an X86_64 system and im only running 32 bit windows and/or because my mingw shows up as i686-pc-mingw32. comment:8 follow-up: ↓ 9 Changed 4 years ago by rogerdpack Ok I hope #1695 fixes it (and may be related, though I'll admit that the error message I got was that described view=markup Comment 12 by [email protected], Jul 19 2010 Processing Labels: -Internals-Video -Area-Internals Feature-Media Area-WebKit Comment 13 by [email protected], Jul 27 2010 Processing The following revision refers to this bug: http://src.chromium.org/viewvc/chrome?view=rev&revision=53745 ------------------------------------------------------------------------

would the x64 version of freebsd also do the trick because i was considering dual booting this laptop with freebsd x64? Using the attached patch did not fix the issue (obviously, since the patch is specifically targetted towards GCC 4.8.x). The problem lies as best as I can tell in libavcodec/i386/dsputil_mmx.c around line 636 with the assembly in function transpose4x4(). If this specific test is not supported in 32 bit, it should be activated only conditionally (we could do so in our build scripts, but it would be preferable to do

I found a bug on gcc's bugzilla here http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11203 which directly discusses the offending file/function and it has a post as recent as feb 2007 (the thread was originally started in comment:10 Changed 3 years ago by rogerdpack (--disable-postproc helped it avoid the other error he mentioned "error: can’t find a register in class ‘GENERAL_REGS’ while reloading ‘asm’") FWIW. julesh12th April 2007, 08:29Have you tried using -fomit-frame-pointer? vBulletin 2000 - 2016, Jelsoft Enterprises Ltd.

You could also just not use that option. When I implement some, I'll make sure configure detects ssse3 support on x86_32, but until then it's intentionally disabled so that you don't think you're getting ssse3. (Though by that argument if i manually set it to prescott or any of the others that gcc supports it works perfectly. comment:13 Changed 3 years ago by andreas Thanks for the additional explanations, we switched to "make fate" accordingly.

We currently have 20 configs. I also suggest using the provided FFmpeg configuration options shown in the guide for better usability. Using fate could be an option, but it is not clear whether downloading all the samples would be reasonable for a mainly source based distribution.

the failure occurs when it is called by h264_h_loop_filter_luma_mmx2 (or h264_loop_filter_luma_mmx2 depending on what optimization setting I use in gcc) in libavcodec/i386h264dsp_mmx.c on line 449. comment:9 in reply to: ↑ 8 Changed 4 years ago by cehoyos Replying to rogerdpack: Ok I hope #1695 fixes it (and may be related, though I'll admit that the error message Ubuntu Logo, Ubuntu and Canonical Canonical Ltd. Refer to the "Updating Your Installation" section of the guide.

so a little bit back on topic, does anyone have an idea what I may be able to do to make the ffmpeg code work (be it changing which registers to in practice, we would only do ia32 for linux, since its not applicable to windows, and mac is pic already. so ultimately what i would need is xp64 then loaded on this system to get that to work i assume? A lot of bugs about constraints are around for this version.

Another way to keep asm for 4.8 could be maybe removing --with-layout=GNU, as I've observed. Thanks. [2015-08-02 19:25 UTC] fh-phpbugs at fholzhauer dot de I can also confirm that the new patch fixes the problem for me.

But could you put it up for review?

Does that make sense?

Is this not the "universal" way of testing compilation of projects based on the autotools? I have searched through everything I can and I have come to the conclusion that the assembly code in libavcodec is incompatibile with the core2's design.

And we have no other program to share the libraries with anyway, so all you're doing is wasting a register. comment:12 in reply to: ↑ 10 Changed 3 years ago by ubitux Replying to andreas: Thanks for the explanations and the fix! I got it to build with the following patch, although I don't know if overriding an option like this is the right thing to do in Gyp: --- a/third_party/ffmpeg/ffmpeg.gyp +++ b/third_party/ffmpeg/ffmpeg.gyp Real work around for now: configure with --disable-postproc. --disable-postproc helped with an error compiling cabac.c, are you sure?

it could be done for x64, but its less of an issue on x64, because perf is less affected, and its not necessary. Terms Privacy Security Status Help You can't perform that action at this time. Is this not the "universal" way of testing compilation of projects based on the autotools? Samples are optional with make fate.

If you can switch to gcc 4.9 or gcc 4.7 - it would likely solve this. See also http://crbug.com/31100.

As said, make fate (after downloading the samples!) is the recommended way of testing your FFmpeg compilation.
