Bug#898575: In-memory cache grows almost without bound

[Juliusz Chroboczek]

Package: mpv
Version: 0.28.2-1

When streaming over HTTP from localhost, the in-memory cache grows
seemingly without bound (RSS just got up to 700MB).  Running
with --cache=no does *not* work around the issue.

Downgrading to 0.27.2-1 fixes the issue.
