Audio is exactly 2 seconds behind #83

Each stream captured have exactly 2 seconds desync behind video

Firstly I've run mostly example configuration with no change to yt-dlp command. Default one as in example livestream_saver.cfg

When noticed the issue I've run yt-dlp command directly but reduced version: yt-dlp -f bestvideo+bestaudio --live-from-start <youtube_stream_link> Left it for the night and it end up being perfect, no sync issue

Updated command in livestream_saver.cfg to be the same with only -f and --live-from-start arguments and nothing changed, still each stream recorded has that exactly 2 seconds desync

What can I try to fix the issue?

I did not notice this bug on my side (yet) but it's definitely related to yt-dlp.

Make sure that the yt-dlp you are using in your virtual environment is up to date. This is separate from any yt-dlp client you have installed on your system, we're talking about the library package of yt-dlp in this case:

source path/to/venv/bin/activate
pip install --upgrade yt-dlp

Be wary that the yt-dlp configuration is done in ytdlp_config.json currently. The example ytdlp_command variable in livestream_saver.cfg is only used by hooks (for example: on_upcoming_detected_command, etc.)

This is not something I can fix, but thanks for reporting anyway. Will keep an eye on this.
