Hi ffmpegers,

when transforming a video from MOV to FLV i get the warning
"[mov,mp4,m4a,3gp,3g2,mj2 @ 0x12180c800]max_analyze_duration reached".
This is my command/output:

Two questions:
1) Is this a warning I have to worry about?
2) Are there any obvious important options missing if I want to have
good video quality?

Cheers, Michael!
