Cannot play flac stream #354

Closed parkmino closed 6 years ago

parkmino commented 6 years ago

I tried to play an flac stream - http://rondo.iradio.fi:8000/klasu.flac It does not play and no progress while there's no problem to play with mpv, vlc and gst123. Could you please check this on your side?

I run $ mpc add http://rondo.iradio.fi:8000/klasu.flac $ mpc play and mpd does not respond. Please let me know what I should do to send you log file or something like that. Do you play the http://rondo.iradio.fi:8000/klasu.flac by mpd ? And then I should close this issue.

$ mpd --version Music Player Daemon 0.20.21

I'll reopen this as soon as you have added the missing information I requested from you.

parkmino commented 6 years ago

I understand your comments however I do not know what I could do it more to clear this issue. Have you ever tried the stream http://rondo.iradio.fi:8000/klasu.flac ? I do not receive any feedback from you except the fundamental comment.

Setups with buffer settings are unsupported, so this alone would qualify for closing this issue for good. Just don't mess with those settings! But the cause for your problem is trivial to find somewhere else, it's a true PEBCAK: you're trying to play an OggFlac stream, but you explicitly disabled the OggFlac plugin. For reasons only you know. Duh!

parkmino commented 6 years ago

No. oggflac decoder only affects to ogg not flac. Enabling oggflac does not resolve this issue. Have you ever tried the flac url and no problem on your side? Then I will accept that it is my fault.

parkmino commented 6 years ago

OMG, it takes too long to play this url. It plays the url after several minutes without changing my configuration. It works anyway but it takes too long!

MaxKellermann commented 6 years ago

Yes, I can play the URL just fine, but that doesn't prove it's your fault. That alone wouldn't justify closing your bug report.

Our real problem right now is that we can't agree on a common logical base. I'm very certain that the stream is OggFlac, which can be proved by looking at the Content-Type header. But you reject this fact. I can't help you that way, without being able to revert to logic.

MaxKellermann commented 6 years ago

As I already wrote, don't mess with buffer settings.

parkmino commented 6 years ago

Hmm... I commented out disabling oggflac and restarted mpd, it plays well. Enabling oggflac seems to be necessary and buffer settings are not changed though. Thanks for your feedback!

MaxKellermann commented 6 years ago

Sigh. Two things are wrong with your last reply.

  1. no, enabling oggflac is not necessary because it is enabled by default. You disabled it explicitly, and you disabled lots of other plugins, for whatever reasons. I don't know, and I cannot image why you would want to do that. See, your case demonstrates exactly why I refuse to even look at a problem without all the information. People think I am rude, but it's really people who post incomplete issue reports are rude towards me, because they waste my time.
  2. yes, buffer settings are changed, as visible in your mpd.conf paste. You said you "commented out disabling oggflac" but you did not mention that you removed the buffer settings. Maybe you just forgot to mention that, but it's terribly hard to help you if you omit vital parts of your story. See above.
parkmino commented 6 years ago

It might be absurd to you that disabling not used codecs and changing buffers affects to sound quality. At least disabling features save the system resource slightly though. It is good for mpd to have options to change it.

MaxKellermann commented 6 years ago

Again all of your points are wrong.

  1. the codec you disabled was not "not used"; it was vitally necessary for the stream you wanted to play
  2. I did not say that changing buffers affects sound quality, but yes, it can
  3. changing buffers can affect lots of things and can cause lots of problems (for example complete failure to start playback, or slow playback, stuttering and more); of course you can do that if you want, but I'll refuse to help you if you run into trouble (your freedom and my freedom)
  4. disabling those features at runtime doesn't save system resources; disabling them at compile time would
MaxKellermann commented 6 years ago

I think I misunderstood your sentence about "changing buffers affects to sound quality". Your sentence was a bit obscure. You said something might be "absurd to me", but other than pointing out a possible absurdness, it did not say anything, it had no point.

parkmino commented 6 years ago

That's what I said it might be absurd to you. I do not want to argue about the sound quality and anyway it is good to have options to change. My buffer settings are not far from the default 4096KB 10%, it might not cause serious problems.

MaxKellermann commented 6 years ago

I'm going to lock this thread now, because your self-inflicted issue is solved, and I feel that my ongoing explanations are not helping you. In any case, please refrain from reporting problems or seeking any other sort of help from this project as long as you insist on those buffer settings.
