ffmpeg cannot decode that file or that file's audio, due to the reasons
given in its output messages. I haven't found any software which is
capable of decoding this file.

Does VSPlayer also play the audio? Perhaps it's just smart enough to
ignore it. (You can let ffmpeg ignore it by demuxing only the video,
with e.g. "-map 0:v".)

Whoever sent that script didn't analyze the issue to realize that
ffmpeg couldn't decode the file.
