I have FreeBSD 10.2-STABLE r289418, ports tree r399880, firefox-41.0.2,1 with ffmpeg-2.8_1,1 as dependency. On i386 architecture firefox crashes when playing any HTML5 video. On amd64 with same revision level I have no this problem. I started firefox from gdb I got this output: Program received signal SIGBUS, Bus error.

I updated ports to 406736r and updated ffmpeg to 2.8.5,1 and firefox to 43.0.4_1,1 and still have this issue. But with SSE=off for multimedia/ffmpeg firefox can properly play youtube videos.
> But with SSE=off for multimedia/ffmpeg firefox can properly play youtube videos. Bug in multimedia/ffmpeg on i386. One more example: sometimes my vlc crashes with multimedia/ffmpeg SSE=on too, but work perfect with multimedia/ffmpeg SSE=off.
I think, in this case my bug may be marked as duplicate for Bug 205958. *** This bug has been marked as a duplicate of bug 205958 ***
