git log -p 3e1cf49 shows you the change in commit 3e1cf49 
(a version that you know is bad) and all prior commits, the 
first commit before 3e1cf49 is 2107009 that as you know is a 
good version, so you only have to revert the one line from 
commit 3e1cf49 but none of the (several ten-thousand) 
earlier commits.

I hope this clears it up, if not, try to remove 
"&& has_decode_delay_been_guessed(st)" from 
compute_pkt_fields() in libavformat/utils.c
