Even if it only happens some of the time, any links to Twitter posts where it's happened before?

A Former User

I'm using another browser based on Chromium (don't know if I can say the name of it) and I have the same problem. But the thing is... it doesn't happen on any other website, only on Twitter. So it might be a Chromium bug or twitter player bug.

You can name other browsers here.

Contacted devs about this months ago.They wanted bunch of information and than said they couldn't reproduce the issue and stopped responding.I still have this problem and as they can see a lot of people also suffers from the same thing.

Problem is still there. Has been here for a long time. I honestly wish there was paid version of Opera or bounty programs that would allow us to pay Opera devs so they could fix these huge bugs.

Windows 10 Edu (1803) 64-Bit
Opera 58.0.3135.127 (latest as of writing)
WidevineCDM 4.10.1196.0

Audio cuts off 9 seconds in. The last 2 seconds can be heard after a second playback: https://twitter.com/xxGodsLastGift/status/1114036356576088064

Tried without ad-blocker
Tried in Opera Beta 60.0.3255.20 (no extensions) (latest as of writing)
Tried in Opera Developer 61.0.3275.0 (no extensions) (latest as of writing)
No flags touched
Tried an new user account, clean profile, same problem

Works in Chrome 73.0.3683.103, Firefox 66.0.2, and Edge 42.17134.1.0 (all latest as of writing)
On these browsers where it works, at 9 seconds the audio jumps in volume and also has a different sound to it as if it changed mics(?)

I tried replacing the files in Opera's WidevineCDM folder (C:\Users[username]\AppData\Roaming\Opera Software\Opera Stable\WidevineCDM\4.10.1196.0) with the files from Chrome's WidevineCDM folder (C:\Program Files (x86)\Google\Chrome\Application\73.0.3683.103\WidevineCdm). Even tried replacing the whole WidevineCDM folder with Chrome's.
Still same problem.

Opera is using WidevineCDM 4.10.1196.0 while Chrome is using WidevineCDM 4.10.1303.2

This is intermittent. Some videos work fine, others don't. The video in the Tweet that I linked above fails every time in Opera and works every time in every other browser.
Twitter (and Facebook?) is almost unusable in Opera with this problem.

There's another thread on this too: https://forums.opera.com/topic/30327/twitter-videos-sound-problem

Having the same issue since so long but now I've had it.. the audio stops after 8-9 seconds in most videos on twitter & returns at the end of video.. It's really irritating. Also making the video fullscreen solves the audio issue but freezes the video itself. What is going on!
Tried everything, only solution is to copy tweet link & watch video on other browser.

Using version 58.0.3135.127
Win 7 64bit

It shouldn't make a difference, but try it anyway. In Opera, goto the URL opera://flags/#autoplay-policy and set it to "No user gesture required".

I can confirm with this one. This is a decoding issue. There's something significant about 9 seconds. If you listen to it in Chrome, at 9 seconds is when the sound switches to louder etc. and that's exactly when the audio cuts out in Opera.

Looking at opera://media-internals after playing the video, I see it's streaming blobs of the video/audio data and it switches to mono or something midstream.

Selected WMFAudioDecoder for audio decoding, config: codec: aac, bytes_per_channel: 2, channel_layout: 3, channels: 2, samples_per_second: 44100, sample_format: 2, bytes_per_frame: 4, seek_preroll: 0us, codec_delay: 0, has extra data: true, encryption scheme: Unencrypted, discard decoder delay: false

Same issue with Vivaldi. I guess the Windows Media Foundation that Opera and Vivaldi use to decode the audio doesn't like the channel count switching like that.

Are the videos that have this problem usually TikTok videos embedded in Twitter?

Tried it, still the same.

Here's another example that I bookmarked:
https://twitter.com/juventusfcen/status/1114541160213749760

Different length (1:23) yet the audio still cuts out at 9 seconds and comes back for the last 2 seconds (on the second playback).

I've noticed that it's from videos recorded & uploaded from mobile (vertical footage). Maybe they recorded it with the stock camera and uploaded it to Twitter or used the in-app camera (doubt it)?

If it is because of mobile (where the footage was recorded) then I don't know if it's the iOS's encoder or Android's encoder that Opera doesn't play well with.

The more patterns we can pull from more examples that we post, we can probably narrow down the cause.

It's a known issue (DNA-74703) and why the audio cuts out is known. However, it's not an easy fix to work around the issue. It needs reworking of the audio handling to fix it. Same for Vivaldi. Same for Firefox on Mac (I hear). The audio works fine on Firefox for Windows as they did some reworking that makes things work. As for Safari, the audio works, but Twitter serves up the audio to Safari in a different way, so that's not a great comparison. The reason it works in Chrome is because it uses ffmpeg for media instead of the Windows Media Foundation. It works in Edge too.

So, it's possible to fix in Opera. It's just going to take some work if Opera is able to provide the dev resources to do it.
