Version: 7:8.1-3
Severity: normal
First of all: Thanks for the amazing job you do with maintaining ffmpeg
(and mpv), which makes it a breeze to (make custom) build(s) :-D
Because of that I had been running git snapshots of ffmpeg and had
encountered some issues for which I wanted to test if one of those
(minor) fixes would be appropriate for Debian.
While building it locally, it failed in tests with filter-frei0r-filter:
```
Test filter-frei0r-filter-unaligned failed. Look at
tests/data/fate/filter-frei0r-filter-unaligned.err for details.
Test filter-frei0r-filter failed. Look at

My commit message (from those snapshot builds) where I disabled those
tests (as I didn't know how to properly fix them):
```
d/rules: Disable filter-frei0r-filter* tests
There was an upstream bug wrt frei0r plugin fixed in commit
549b45459e4c ("avfilter/vf_frei0r: fix time not being passed in seconds")
That commit added a test for it, but that test fails on my system.
Error message: "Could not find module 'distort0r'"
But that module is available via the frei0r-plugins package at
/usr/lib/x86_64-linux-gnu/frei0r-1/distort0r.so
I think /usr/lib/x86_64-linux-gnu/ is likely included in the search
path, but possibly the 'frei0r-1' subdir not.
I do not (yet) know how to fix it, so disable that test for now.
Another frei0r test got added, which also failed, in commit
4c4ab2ec6ff9 ("fate/filter-video: add frei0r test where input is realigned")
Its commit description mentioned 'FREI0R_PATH', which makes it likely
this is indeed a PATH issue. Disable this test too.
```
It could be completely bogus/irrelevant, but I'm quite sure you will be
able to tell that. If not, hopefully the above gives a useful hint.
Cheers,
Diederik
