Bug 272788 – [GStreamer] Does not play sound correctly when using some video players

• Component: Media
• Status: RESOLVED INVALID

[Aleksandr Shamaraev]

Hello.

When playing video from some platforms, the audio track does not work correctly (clicks, crackling, voice). There is sound, but the words are unintelligible, and the sound itself is not entirely correct.

For example, there is a problem when playing a video
https://rutube.ru/video/aef32c5e5ec079e8a2dc3587b0c493e3/

But if, for example, you watch YouTube, then there are generally no problems with voice and sound.

There are also problems with sound in other video players on the Internet.

Unfortunately, I don’t know what could be the reason.
At first I thought that the problem was related to the Epiphany package and created a report there

https://gitlab.gnome.org/GNOME/epiphany/-/issues/2315

But from there I was redirected to you.

Hello 
Created a log using MiniBrowser

In MiniBrowser the situation is the same as in Epiphany

Hello.

No, Epiphany release.

$ epiphany --version
Web 46.0

But when I wrote a report in Gnome, I collected the package on my computer and checked it.

Epiphany 46.0-32-g650105b3

Everywhere the result is the same with sound.

The audio decoder used in your pipeline is avdec_aac, known for various issues.

Please install the gstreamer fdk-aac plugin.

Hello!
Thanks a lot.
Everything worked.

Can we make WebKit refuse to use avdec_aac instead of just misbehaving?
