[BUG] Can't seek the timelapse (self-hosted server only. Chromium-based browsers only)

We've found out that this happens on chromium-based browsers on all platforms (including Android) This also probably isn't a recent bug, because it has been happening since I installed TSD (more than half a year now) And also, we didn't test it on the official TSD, only on our private instances

Disclamer: I'm not a JS developer. I debugged a bit and found that something goes wrong in video.cjs.js:21722 when getting the currentTime. The value will be 0 if setCurrentTime has been called before.

Player.prototype.currentTime = function currentTime(seconds) {
    if (typeof seconds !== 'undefined') {
      if (seconds < 0) {
        seconds = 0;
      }
      this.techCall_('setCurrentTime', seconds);
      return;
    }

    // cache last currentTime and return. default to 0 seconds
    //
    // Caching the currentTime is meant to prevent a massive amount of reads on the tech's
    // currentTime when scrubbing, but may not provide much performance benefit afterall.
    // Should be tested. Also something has to read the actual current time or the cache will
    // never get updated.
    this.cache_.currentTime = this.techGet_('currentTime') || 0;
    return this.cache_.currentTime;
  };

When you click to scrub, the currentTime value will be set by the mouseMove event, but setCurrentTime will raise an exception and not set the currentTime property correctly. Later, on the second call (see image below) it will return 0:

See Watch in the top right: currentTime = 0:

And so the currentTime goes back to 0 and the players starts to play from there.

Interesting. Do you know the reason why it's reset to 0? If so, can you fix it in a PR. Please remember to open the PR toward the master branch, not the release branch.

I think it's never set in the first place. It looks like an upstream problem to me, but like I said, I'm not a JS developer. I can't test updating the dependency in obico, especially because it seems that the next version (6.x) is a breaking change. They even renamed the package.

Hi folks, I am new to Obico. I built it out on my K8s and for the most part, it works. I have yet to have a spaghetti mess on my hands to test it out, but I am finding a couple of functions are not working.

The server does not have a tsd-timelapses folder. It does have tsd-pics, and I have done prints that take longer than the minimum threshold.

The screenshot is from my server container and I am reading about the pathing here https://obico.io/docs/server-guides/ops/#access-timelapses-stored-on-your-server

I know that location is writable since I see it in the logs. I can also touch a new file in that folder.

What should I be looking for to diagnose this further?
