Turns out this was fixed after switching from ffmpeg-full-git to ffmpeg for whatever reason.

mpv on Arch (svp installed from AUR; both mpv-full and mpv-full-git tested) seems to crash with 

free(): invalid pointer

on all video files I have tested.

mpv command line:

mpv --no-config --input-ipc-server=/tmp/mpvsocket --hwdec=no --resume-playback=no ~/Downloads/A.Certain.Scientific.Railgun.S01E09.1080p-Hi10p.BluRay.FLAC5.1.x264-CTR.\[0225EA9C\].mkv

The crash also happens if I replace 

input-ipc-server

with 

--vf-add=vapoursynth=$HOME/.local/share/SVP4/scripts/ca386e69.py:4:25

.

Stack trace using gdb is as follows.

Running mpv with 

MALLOC_CHECK_=0

did not help.

On the other hand, VLC works just fine.

DId I miss anything?
