mp4 videos are not displayed when deployed on github.io

See https://input-output-hk.github.io/cardano-updates/posts/2022-09-27-network.html

I think the files are somehow corrupted: I could not open the files locally either with QuickTime or VLC.

I can play this locally with mplayer, vlc, and totem. It is also correctly identified by file:

images/p2p-relay-5.mp4: ISO Media, MP4 Base Media v1 [ISO 14496-12:2003]

Here is what I have from a fresh checkout on Mac OS X:

s % ls -la images

and then

s % cat images/p2p-relay-5.mp4

What am I doing wrong?

[dnadales]

Perhaps you're missing https://git-lfs.github.com/

We should mention this in the README :/

Indeed. And perhaps the GH action is missing it too :)

Or not using it at all?

I understand it's annoying to store large video files in Git, but perhaps we should just store them elsewhere and only reference them in markdown by URL?

[coot]

It would be much nicer to store them elsewhere, any suggestion? Maybe we could serve them from google 🤦‍♂️ 😄

I think that would make sense: Upload the videos to a shared google driver directory and make world readable. Requiring people (or the CI) to install a git extension does not seem very UX-friendly
