avformat_input_error code -2

[juliohm]

I am trying to read a mp4 file that was converted from a dav fil\e using ffmpeg:

ffmpeg -y -i input.dav -c:v libx264 -crf 24 output.mp4

Solution suggested here.

The VideoIO.jl is showing the following error:

Could not open data/output.mp4. avformat_open_input error code -2

Do you know what this error code means? I tried searching online, but couldn't find a good resource.

I have the same error on some specific videos in a set of almost identical ones.
