#33343: Ffmpeg does not include CPU capabilities on 64bit 10.7.3 -----------------------------------+---------------------------------------- Reporter: sonniesedge@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.3 Keywords: ffmpeg | Port: ffmpeg -----------------------------------+---------------------------------------- Comment(by sonniesedge@…): Some more: Using Xcode 4.1 Tried adding in --enable-mmx and --enable-mmx2 to the portfile. Ffmpeg builds successfully but still reports as using no CPU capabilities. -- Ticket URL: <https://trac.macports.org/ticket/33343#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS

#33343: Ffmpeg does not include CPU capabilities on 64bit 10.7.3 -----------------------------------+---------------------------------------- Reporter: sonniesedge@… | Owner: devans@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.3 Keywords: | Port: ffmpeg -----------------------------------+---------------------------------------- Comment(by merseyparadise@…): I think this may be an issue with libx264 rather than ffmpeg in general. I get the same issue with the x264 port, but managed to get capabilities working with a version I built from source. Also I've only seen the problem in conversions using libx264, e.g.: [libx264 @ 0x7fb4b0844800] using cpu capabilities: none! I've also used this version of ffmpeg as an output via yuv4mpegpipe and a fifo to my separately-built x264, and it uses all capabilities. That said, the issue may be more general, or you may already be aware of the stuff I've mentioned. Hope it is of help, though. -- Ticket URL: <https://trac.macports.org/ticket/33343#comment:4> MacPorts <http://www.macports.org/> Ports system for Mac OS

The bad news is that is segfaults as soon as you use ffmpeg with the -vcodec libx264 option. Yay. -- Ticket URL: <https://trac.macports.org/ticket/33343#comment:6> MacPorts <http://www.macports.org/> Ports system for Mac OS

While we're waiting for a fix, a workaround is to uninstall the ffmpeg port, uninstall the x264 port, compile x264 after editing configure to use CC=clang (I've since found out that CC should be llvm-gcc, but clang seems to work), and compile ffmpeg with: ./configure --enable-gpl --enable-postproc --enable-swscale --enable- libmp3lame --enable-libvorbis --enable-libtheora --enable-libdirac --enable-libopenjpeg --enable-libxvid --enable-libx264 --enable-libvpx --enable-libspeex --enable-shared --enable-pthreads --cc=clang --extra- cflags=-I/usr/local/include --extra-cflags=-I/opt/local/include --extra- ldflags=-L/usr/local/lib --extra-ldflags=-L/opt/local/lib ...which are the same options that the port uses, apart from setting the compiler as clang and dragging in your x264 libraries from /usr/local/bin. Works a treat. Now all I need is a set of updated presets... :) -- Ticket URL: <https://trac.macports.org/ticket/33343#comment:8> MacPorts <http://www.macports.org/> Ports system for Mac OS

[[BR]][[BR]] compiling x264 with clang led to segfault regardless of which compiler was used to build ffmpeg. Replying to [comment:8 merseyparadise@…]:
