Comment:

 You're right. avf->start_time is the start time of the output format
 context, that's why it is unset, the code should use the input format
 context, which is  cat->avf->start_time like you said.

 I'll make a patch and submit it to ffmpeg-devel.

 Thanks for figuring this out, and sorry for the regression.
