Not editing/moving/creating boxes with local (own) videos

[AVCarreiro]

I can use the tool as supposed with the sample data (the local 0.mp4 in /static/videos/ or the ones in S3). However, when using my own videos, locally in the same folder, although the video plays correctly, I can't do anything after drawing the first box: editing, moving, creating a new one, etc. Just stuck there.

Confirmed they're H.264 encoded. Tried using the convert-to-h264 script, all the same, and different browsers (Chrome, Firefox and Edge).

Any hints on what might be the issue here? Thank you!

Investigating this issue further, I tried reverting some commits (to ca28392) and it works on Firefox (not on Chrome and Edge though).
