Twitter video's sound gets muted.

  • @leocg thank you for the information!

  • @leocg yes from second to al the next.

  • Hi all - any news on the fix?

  • I thought I was the only one having this issue!

  • 3 MONTHS, THREE, FREAKING, MONTHS!*
    Come on guys! What y'all doing over there?
    Fix this, for the sake of god.

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

  • 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.

  • @leocg It's Vivaldi.

  • this may or may not help sum...
    try this..

    Look @ your WidevineCdm folder version..

    is it this version 4.10.1146-96.0

    if so go back to this version 4.10.1146.0

  • same problem.. pls FIX !!!!

  • 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.

  • same problem...

  • 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

  • @bninja96 same 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

    audio decoder config changed midstream, new config: codec: aac, bytes_per_channel: 2, channel_layout: 2, channels: 1, samples_per_second: 44100, sample_format: 2, bytes_per_frame: 2, 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?

  • @burnout426 said in Twitter video's sound gets muted.:

    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. 👍
