--- Comment #7 from Christopher Neufeld <glibcbugs0001 at cneufeld dot ca> ---
I realized that the x264 worker threads were running in libx264, which is not
actually part of the ffmpeg build. Further, it was over four years old,
libx264.so.120. So, I built an up-to-date libx264, version .so.148. I then
recompiled ffmpeg with the updated libx264, and the slowdown in glibc-2.23 is
no longer present.
I'm closing this bug WORKSFORME in light of these new discoveries.
