Please remember that only current FFmpeg git head is supported, both here and on the bug tracker. Can you reproduce with ffmpeg, the command line application? Please understand that you cannot report performance regressions for builds using "optflags", feel free to run a bisect if the issue is not reproducible with ffmpeg and if it is reproducible without using "optflags" (and with using the same toolchain and either static or dynamic linking for both builds, mixing them makes no sense for performance comparison).
