It’s not clear what is the problem you are trying to solve, but
from the patch I suspect that it’s about seeking to a key frame
instead of a frame pointed out by the start time. It’s believed
that it’s a caller responsibility to provide correct start time.

hi

to get a precise start time for a key frame ? It is very very
difficulty
to caller.

in addition, most people use this module to do a integer cut ,like
0s-10s
10s-20s 30s-40s…

it
into hls.
Thank you!

The module is was originally designed to be used in Flash-based
pseudostreaming, and flash players are perfectly able to use
correct seek points.
