The faq states that the 3 percentages are:
video codec CPU usage in percent, video_out CPU usage, audio codec CPU

here the typical status line is:
A: 4.1 V: 4.1 A-V: 0.003 ct: 0.072 93/ 93 30% 26% 1.8% 13 0 0%

here it is:
A: 7.7 V: 7.2 A-V: 0.468 ct: 0.172 53/ 53 38% 26% 78.6% 49 0 0%
this is the percentage of CPU used by the audio codec: 78.6% vs 1.8%.
How can it be so high? Maybe a timing problem/PTS mismatch?
It's becoming an interesting issue, worth investigating :)
