Error when adding a media item while a playlist is not saved

[JunioCalu]

Possible steps to reproduce the error:

1. Delete the currently playing playlist, if one exists.
2. Restart ffplayout if the playlist was deleted while a clip was being displayed.
3. Add a media item to a playlist.
4. Add a title to the playback item.
5. Save the playlist.
6. Navigate to a different settings page, "/message", for example.
7. Return to the player page.
8. Add new items to the playlist.
9. Do not save the playlist.
10. Navigate again to a different settings page.
11. Return to the player page.
12. Attempt to add more media items to the unsaved playlist.

Additional observations:

1. After each page switch between "/message" and "/player", the "/player" page should be refreshed using the F5 keyboard shortcut.

2. In this case, the ffpapi was compiled with the "embed_frontend" feature disabled.

3. It appears that this bug is overwriting the web frontend installation files, and the only way to remedy it is to uninstall and reinstall the ffplayout installation package each time it occurs.

I found some other little issues, but I was not able to reproduce this one.

[JunioCalu]

New error:

Possible steps to reproduce:

1. Add a media item to the playlist.
2. Set a title for the item.
3. Do not change the "duration".
4. Set "in" to 00:01:000.000.
5. Set "out" to 00:01:59:000.00 (the missing last "0" is intentional).
6. Save the item.
7. Save the playlist.
8. Refresh the page (press F5).
9. Try to add another media item to the playlist.

Additional configuration:

{
  "channel": "Channel 1",
  "date": "2024-05-13",
  "program": [
    {
      "title": "jjjjjjjjjjjjjj",
      "in": 0.0,
      "out": 119.071927,
      "duration": 119.071927,
      "source": "/var/lib/ffplayout/tv-media/filler/filler.mp4"
    },
    {
      "in": 60.0,
      "out": 119.0,
      "duration": 119.071927,
      "source": "/var/lib/ffplayout/tv-media/filler/filler.mp4"
    },
    {
      "in": 0.0,
      "out": 119.071927,
      "duration": 119.071927,
      "source": "/var/lib/ffplayout/tv-media/filler/filler.mp4"
    }
  ]
}

Console log:

Update, another way to trigger the same bug:

1. Add a single media item to the playlist.
2. Save the playlist.
3. Exit the "/player" page and navigate to different pages such as "/message" "/logging".
4. Return to the "/player" page.
5. Refresh the page by pressing F5.
6. Result: The playlist disappears from the screen and it is not possible to add any more items.

Note: Tests are still being conducted on an ffplayout binary compiled with the "embed_frontend" option disabled.

I don't know why, but I can't reproduce this error. Not in a released version, and not in dev mode.

[JunioCalu]

I don't know why, but I can't reproduce this error. Not in a released version, and not in dev mode.

In my tests, this bug is linked to the configuration in the image below, while the default installation configuration seems to be working fine.

[jb-alvarado]

Ah that brings light in this issue.

[JunioCalu]

Thanks, I'll see if I can test this today or find a new bug.
