Nothing severe AFAICT.

It's just that all the little bits are adding up, making it
really hard to find a way to go that's not too cumbersome.

Please note that above is only an assumption because AFAIK there
is likely nobody that has the complete knowledge of the problem.

I fear it's not that simple :(

I have been wanting to improve the state of the build system
for a few years now. I still haven't managed to come up with a
precise plan that is obviously an improvement and would
predictably be not too much work.

I fully agree that we should change something. It feels like the
configure fixes we need to implement because of the way we embed
internal FFmpeg are way too costly. Personally I have the impression
those pure maintenance commits are hindering me from doing actual
MPlayer development.

OTOH I think we should look at some VCS data, because feelings are
feelings. I will open a new discussion thread for that. Hopefully
including a patch that will ease maintenance by running FFmpeg's
configure. Motivated by your comment, I have tried to implement that
and it looks promising so far.

@Etienne:
The mentioned patch could make your patch obsolete. So it's probably
better to not invest more work into it like I originally suggested.


Best regards,
