[FFmpeg-devel] [RFC PATCH 0/2] Make fate tests succeed with zlib-ng

[Alexander Strasser]

This is as subject notes an RFC. I wanted to send it out quickly.
Didn't actually test on zlib systems yet (old and new).

So it is not that heavily tested yet and maybe has rough edges I
didn't notice.

I hope this would help to unbreak zlib-ng systems and not disturb
systems with older zlib versions.

The strategy is

1. re-apply Ramiro's patch to use compression level 0
2. fix the 2 tests that fail with older zlib with extra ref file

The mechanism should only be used when other solutions are not
available. The alternative files could be dropped in the future
e.g. when no more fate clients fail because of it.


Best regards,
  Alexander
