@Milhouse Just to offer an insight from a different POV, my crappo OS is not Libreelec,
and I use slightly different versions of some pieces of software and I rely on shared libraries (if that matters), but kodi codebase is the same (newclock5) and HEVC ffmpeg patches are the same.
I' ve just played elysium sample like 15 times - and yes, there is a leak here too,
the monitoring was done by bcmstat.sh.
The file was played from nfsv4 source, kernel fstab mount.
320MB ram assigned to GPU.
I use the tip of glibc release/2.26 branch, no MMAP_THRESHOLD set.
So if it's glibc bug - it's not fully fixed as of current tip of glibc 2.26 branch.
After 15 playbacks I still had 355,148 kB/49.4%,
however the situation here is a lot better than reported by others in this thread.
There results are inconclusive, on average full reproduction of the sample leaks ~24MB of ram, but sometimes after playback the ram is freed and after around 30 secs even more ram is freed and I get more free ram than before playback.
Here is how it looks when the ram is freed (this does not happen always):
