Theres something about your statements, the one above as well as the
ones in other mails in this thread that i dont fully understand

You said in this thread that "i'm not a developer
and have not written one line of code for libav. i dont even read
the mailinglists"

and IIRC you also didnt read the ffmpeg mailing lists in the time
before the fork, except some specific threads, nor are you on the
ffmpeg IRC channels and i belive you arent subscribed to the FFmpeg
mailing lists now either. I definitly found a unsubscribe statement
for your address from march 2011 in the logs.

Given that, how can you even know anything about FFmpeg or what its
developers do or say or not do or not say

FFmpeg development discussions are mainly on our mailing list. with
a tiny bit on our IRC channels

I know you did read some specific threads which where related to
the fork as you participated in them. But these where possibly the
most heated and aggressive discussions we ever had on
ffmpeg-devel. And certainly are not representative for FFmpeg either
before or after the fork.

normally (for example in the kernel) code is reviewed before it is
pushed and not when it is merged.
Yet i _try_ to review and test what i merge from libav.
To proof that, here are some examples of bugfixes and decissions
based on such reviews. These wouldnt exist if the code wouldnt be

4 days ago:
libav added some () to a condition:

on the ffmpeg side the code was instead changed the following way a
year ago
libav decided not to pick this change, and instead made their own
different change as shown above

and in the merge i tested both to double check that our solution is
correct and libavs isnt, and kept our solution.
More precissely libavs breaks decoding of

or for example 16days ago
libav fixed a few memory leaks
but they used the wrong deallocation function, that is free() instead
of av_free*() which can lead to memory corruption,
Multiple people noticed that and it was fixed in the same git push
that pushed the merge
also there where multiple other related issues found when reviewing
the change from libav which where fixed in ffmpeg in the same push as

but either way, id like to suggest again, we move forward and
rather discuss how we can improve the situation, do something about
the split and move toward un-doing it!
