Most Youtube videos work perfectly but a few Youtube videos not working in Opera

@victorxstc It can be a codec issue. Can you access Statistics for Nerds on those videos that doesn't play?

Any difference if you disable extensions and adblocker?

victorxstc

victorxstc @leocg

@leocg yes, stats for nerds shows no codec for the failed video:

Viewport / Frames 777x437 / -
Current / Optimal Res 0x0
Volume / Normalized 15% / 15% (content loudness -1.5dB)
Codecs
Color

Disabling all the extensions and restarting Opera did not help.

@victorxstc While trying to watch one of those videos, check opera://media-internals and see if it shows any error message for that playing.

victorxstc

victorxstc @leocg

@leocg I tested 4 of the previously failed videos. To my surprise, 2 of them played smoothly this time (without me doing absolutely anything)!! But 2 others still fail to play.

I tested one of the failed videos with opera://media-internals info. It gave these 4 errors:

What does https://html5test.opensuse.org/ in Opera say for h.264 and opus?

victorxstc

victorxstc @burnout426

@burnout426 it says it has both of them. However, I have now installed the codecs externally. I wish I had checked this before installing the codecs so that I could see whether my Opera lacked codecs for them or not.
Anyways, now I can watch all previously failed videos. Though it still lacks some codecs like h.265:

@victorxstc In the previous posts, the log seems to show that the problem was with the AAC codec.

victorxstc

victorxstc @leocg

@leocg All reports are for the same video. is it possible that Youtube has changed the codec of the said video from AAC to H.264?

leocg

leocg Moderator Volunteer @victorxstc

@victorxstc Nope, because AAC is an audio codec and H264 is a video codec.

Usually they are together.

If you change your YouTube settings to use AV1 on low resolution videos, does anything changes?

What specifically did you install?

victorxstc

victorxstc @leocg

@leocg Thanks for explanation.

If you change your YouTube settings to use AV1 on low resolution videos, does anything changes?*

Apparently it needs me to sign into my Youtube account. I am using Opera without an account.

I logged into my account and set it to always use AV1. But no change happened. Please note that my problem was resolved a couple of days ago after installing external codecs; so we should have tested this AV1 setting beforehand.

@victorxstc Try the option that I mentioned, to use AV1 for low resolution.

victorxstc

victorxstc @leocg

@leocg There was no such an option. The only available ones were these:

AV1 settings
Auto (recommended)
Prefer AV1 for SD
Always prefer AV1

leocg

leocg Moderator Volunteer @victorxstc

@victorxstc It's the second one.

burnout426

burnout426 Volunteer @victorxstc

@victorxstc Okay. Usually codec packs like that only provide DirectShow codecs that wouldn't help with Opera as Opera uses the Windows Media Foundation instead. But, if things are working for you now, might as well go with it.

victorxstc

victorxstc @leocg

@leocg changed the settings but nothing happened again. Again, I think it is a bit too late for this test. I should check this out in the next installation of Windows and Opera (when the issue exists again).
