Ffmpeg Error Smoperand Has Impossible Constraints
Note: See TracTickets for help on using tickets. I've tested at least on OpenSUSE and gcc 4.8 works fine there (however not directly on i386 but with -m32). I was able to simultaneously encode to mpg and play that output with FFplay. mseaborn, its changed since then. check over here
Comment 9 by [email protected], Apr 20 2010 Processing pic is determined during ffmpeg configuration. Being that this is the new processor architecture and that mplayer/mencoder/ffmpeg is a pretty important piece of software, I come here to ask anyone who knows what their doing in assembly 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 Adv Reply Quick Navigation Installation & Upgrades Top Site Areas Settings Private Messages Subscriptions Who's Online Search Forums Forums Home Forums The Ubuntu Forum Community Ubuntu Official Flavours Support New https://trac.ffmpeg.org/ticket/1176

- 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.
- Probably fair enough to disable for all i386 gcc-4.8 as no guarantee what happens elsewhere.
- 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?
- On ia32 this does not imply -fPIC by default, but -fPIC is normal practice to avoid TEXTRELs and hence allow libraries to share memory, so I'm adding -Dlinux_fpic=1." Why care about
- comment:11 Changed 3 years ago by cehoyos Allow me to repeat that make check does not actually run the cabac test (and that you don't need to run it, it is

Considering that all h264 related code compiled just fine, I guess this should have the HAVE_7REGS check. You could also just not use that option. If that allows to reproduce the problem, please run make again, then run make V=1 and post the complete, uncut output here (please do not post the console output of an http://bashprofile.net/ffmpeg-error/ffmpeg-fix-timestamps.html Doom9's Forum > Programming and Hacking > Development > ffmpeg/libavcodec assembly DOES NOT WORK FOR CORE2!
Refer to the "Updating Your Installation" section of the guide. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. 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.
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
As said, make fate (after downloading the samples!) is the recommended way of testing your FFmpeg compilation.
