sound streams too slow on online TV

Unread post by Bito_MUC » 2019-02-01, 21:49

Hi friends of Pale Moon,

my Pale Moon (v. 28.3.1) running under Linux Mint 19.1. has a problem with TV streams like https://www.zdf.de/live-tv or https://live.daserste.de/ or https://www.arte.tv/de/live/: While I can see the pictures with normal velocity and good resolution, the sound runs as slow as if the movie would run in extreme slow motion, so that you don't understand a single word. It seems that I am not the only one with that issue (see https://forum.palemoon.org/viewtopic.php?f=5&t=16241&p=158839&hilit=sound#p158839. With youtube videos, everything is fine.

I am rather sure that this is not a matter of the more than 10 years old hardware I use, because on the same machine I can watch TV streams without any problem when I use Firefox ESR 51.9 (the last Firefox that uses "legacy" extensions).

Do you have an idea what might go wrong here?
Thank you for your help

Everything works fine on Windows (daserste HD streams fine), so likely something to do with the Linux media back-end (and potentially with very old hardware)
That it works on Firefox 52 ESR for you has little bearing on UXP -- we've made plenty of changes to the media back-end.

(and they are STILL broadcasting "Tatort" in 2019? Wow! Some things never end XD)

I can't actually see any of the streams (I think the site is asking me to install some kind of a player, ZDF-Player ???), but I agree with Moonchild on this. Has to be an OS/driver issue. I've seen similar problems on other OSes... or OS flavors ;).

One solution that helps with some sites is to ensure that you're running in Firefox Compataibility mode. The menu tree walk is...
  • Tools
  • Preferences
  • Advanced
  • Compataibility User Agent Mode "Firefox Compatibility" (at the drop down menu)
And restart the video. I did some testing, and did not have to restart the browser.
There's a right way

And then there's my way

Could the videos be played on an independant player like vmc for example.?

Thank you, Walter. With these changes, my Pale Moon plays TV streams as it should be.
:)
But there is one thing I don't understand: Why does it make a difference whether the respective video stream comes from youtube or from another source? The TV streams I had problems with, aren't really "live" as little as those from youtube, but come from a repository called mediathek or so. But this question, I am afraid, might only show that I am only a stupid user and not a "computer nerd".

Back in the days when I watched TV streams I've seen browsers going audio unsync with stream duration.
Tatort stream in "High" quality runs fine here on xubuntu 14.x-32, Intel 900/2.2 GHz, 1GB (clean cache), even fullscreen.
However, when set quality to "Very High" I get micro hangs in 2 second sequences and audio stream unsyncs very soon. - Just hardware limits.

at Bito_MUC:
From my knowledge there is certainly more than one reason in the chain, like compatibility settings, browser sniffing for automatic settings, some channels limit bandwith/speed, different video "standards" and decoding/playback abilities and not at last, your hardware, video card, drivers, etc. ... so it's a bit more than downloading some bytes and watch them in a player.

thank you for your advice. I did not realise that checkbox before. Now I have checked it and the thread can be closed
