image_field fail to export to anki about mpvacious

[danielhuangsw]

I solved the issue by reinstalling mpv from Ubuntu PPA listed in https://mpv.io/installation/

I believe the bug from mpv-player/mpv#8433 is contributing to the issue. I've updated the the dependency libzimg2 from 2.9.1 to 3.0.1 which can be downloaded from https://launchpad.net/~savoury1/+archive/ubuntu/multimedia/+build/20145772 for Ubuntu 18.04.

Successful output is as follow:

I'm happy to see the issue resolved. To prevent it in the future I'll add a note in the readme.

Check if your build of mpv supports image encoding.

mpv 'test_video.mkv' --loop-file=no --frames=1 -o='test_image.jpg'

If it succeeds, it's a bug in mpvacious. If not, you have to install a build of mpv with the appropriate support.

Here is the output from terminal:

mpv: ../video/zimg.c:241: repack_entrypoint: Assertion `!(i & (mp_repack_get_align_y(r->repack) - 1))' failed.

This test has failed, thus it's not a bug in mpvacious.

Thanks for the test case!
