variable bitrates confusing my legacy amplifier #231

Open eiland-asbl opened 1 year ago

eiland-asbl commented 1 year ago

okay, its really my problem, but i have a legacy amplifier, a TX-8050 , and it has a hard time when i switch between youtube items, the first one is played fine, but then, when i switch to another one, it gets really confused to the bitrate (i assume) and starts playing super warped (slow).

i tried forcing mopidy and icecast2 to resample, but to no avail.

is there a away that mopidy-youtube could send out less confusing audio, for my poor old amp?

Interesting issue, and not something that I've ever come across. I also use an older amplifier (NAD T754). I feed an analog signal generated by an external DAC. My amp doesn't have a USB input, but I have previously had success feeding it a digital signal by SPDIF.

Perhaps you could try limiting the formats that mopidy-youtube uses?

In youtube.py at around line 415 is the code that sets the parameters passed to get the youtube url:

                ytdl_options = {
                    "format": "bestaudio/ogg/mp3/m4a/best",
                    "proxy": self.proxy,
                    "cachedir": False,
                    "nopart": True,
                    "retries": 10,
                }

You could try changing the format line to something like "format": "mp3", to limit it to mp3 only, and see if that helps?

i turned it into "format": "mp3", but then it triggers errors :(
