[FFmpeg-user] How to find the last working GIT version?

[Dennis Volodomanov]

Hello all,

I've got a problem with FFmpeg remuxing MKV to MPEG-TS (video mux, audio 
recode or drop, doesn't matter) and I have the last working build from 
around N-43161-g31d8261. Shortly after (a few days or a couple of week 
at most) that it stopped muxing properly. What I mean by that is that 
video freezes a few seconds into certain videos (not all) and then skips 
further to another frozen frame and so on.

I'd like to try and narrow it down by getting each consecutive day after 
that last-known working build and building to see when it starts to 
break. Can you please supply a git command line to do that?

Also, how can I look at changes between two builds (in source) to see if 
I can spot it myself?

Which files should I concentrate on comparing?

Thanks!
