Short description of error
When rendering from command line, it can't load mp4 video and says: not an anim.
Exact steps for others to reproduce the error
Use a mp4 video as texture:
(Material Properties > Surface > Use Nodes > Surface: Emission > Color: Image Texture (import the mp4 video as texture))
When rendering from UI, every thing works as expected.
But when rendering from command line, it can't load the mp4 and says: not an anim.
The command I use for render is:
$ blender -b MyFile.blend -a
Please help me.
