hi,

Assuming (very wild guess) that the size gain brought by the proposed
changes from #10001 can be extrapolated, this could become 117 MiB.
If that's mostly correct, then with an aggressive enough cleaning
policy (e.g. delete those that are more than 7 days old), I *guess*
that we can very well afford storing those. I guess that our existing
artifacts cleanup script could easily be adjusted to support expiring
videos as well (note that we may need different expiration policies
for videos and for other test suite artifacts, that we may want to
keep longer; not sure yet; needs to be refined).

Excellent news: this means that the runtime increase concern is not
valid on lizard -- one less blocker for archiving videos.
bertagaz also confirmed that archiving them is not much more work for
him, so we should be good.

I think that's not a blocker for the first iteration, though: if videos
are added between Oct. 15 and Jan. 15, I'm happy :)

bertagaz, time to create tickets that sum this up, or do we need
more discussion?

Well, it *is* valid at least on my system. However, it could depend on
hardware, and/or on the version of the video codec libraries (I did my
tests on sid, which is useful info because that gives us an idea of
what software we'll run on our infra in ~2 years).

Cheers!
