Error messages are ignored silently

Hi, thanks for this library. I just tried it, but unfortunately it's not downloading anything.

To debug, I went to l.177 in `download_video.py` and added a print statement on the error. Without it, the error just gets completely ignored unless it's `429` -> not good

With the print I got:

```
Unable to download JSON metadata: HTTP Error 404: Not Found (caused by ); please report this issue on https://github.com/yt-dlp/yt-dlp/issues?q= , filling out the appropriate issue template. Confirm you are on the latest version using
yt-dlp -U
```

Turns out that the locked version of yt-dlp is too old and I had to update it.

With the update, it seems to work now :) but the progress bar always shows 100% and 00:00 - not terrible, but kind of defeats the purpose of a progress bar.

Start in download_video.py around line 177, where the error is currently hidden unless it is HTTP 429, and inspect how the progress bar is updated after the yt-dlp call. Reproduce the failed download with the locked yt-dlp version and a working updated version; done means errors are visible and the progress bar reports meaningful progress and elapsed time.
