No, probably not, but I think that's ok. --with-pic is kind of ugly. You can build if that option is not specified, right? Does removing both --enable-mmx and --with-pic build for you? Does it auto detect mmx and build with it anyway in that case? > > ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): relocation > R_X86_64_32 against `a local symbol' can not be used when making a > shared object; recompile with -fPIC > > ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): could not read > symbols: Bad value > > did not look into it but must be a change after my patch from earlier > this year. This it the error I see, but it's because ffmpeg does not build with PIC, even though the rest of the build does. An additional problem may be that there was trouble building the mmx portion of ffmpeg some time ago with PIC. I need to verify of that is why we've had so much trouble with it. I noticed from your older emails, j, that you were not using internal ffmpeg. I think that is why this was not noticed before. If the build was using external ffmpeg, then I would not expect to see the error you posted.

Well, I think the trouble here is that either ffmpeg should follow the PIC behavior of the rest of the build, or is broken for PIC in general. I saw a note that debian policy required build with PIC for a time. I don't think that will continue, as present comments say PIC should not be required. I do see PIC used in the general Cin portion of the build here on Suse. Do you know, or can you check, if PIC was used in your builds of the main portion of Cin, Graham? Also, if you have a build log, would you show me the compile options of mpegvideo_mmx when it builds? (If it builds... It will only build if mmx is specified or auto detected as true. I'd like to know if it does not auto detect mmx also.)
