Upon request by mru I extended the benchmark somewhat. I didn't bother
doing this with oprofile though.
10 runs decoding 8-bit h264:
| Before | After
-------------------------------------------
| 8.629 | 8.726
| 8.606 | 8.709
| 8.619 | 8.716
| 8.609 | 8.683
| 8.619 | 8.706
| 8.606 | 8.786
| 8.643 | 8.659
| 8.626 | 8.653
| 8.613 | 8.673
| 8.629 | 8.733
-------------------------------------------
Avg: | 8.62 | 8.70
Stddev: | 0.012 | 0.040
-------------------------------------------
From the table follows that the patchset gives a speed penalty to 8-bit
h264 decoding of about 1% (for this clip).
