State of the world update!

Adding a note to this ticket: thumbor should apply deinterlacing on files that indicate interlacing in their video metadata; this will require a quick call into ffprobe.

There's now active work on thumbor again, which should help us actually resolve this. :) I'm committed to help with some documentation on how to add type formats, and trying to bang the MPEG stuff back into shape.

Claiming this, taking a quick look at current status. Worst case this should be doable with a small patch to librsvg's C API and rsvg-convert.

Was with. At least I'm pretty sure. ;)

Could you check whether turning off "check spelling while typing" fixes this? (In the browser's Edit > Spelling and Grammar menu.)

Nope, that looks distinct. But I'll double-check what it generates.

Hmm. Well first we should not throw an exception, if that's not resulting in a proper API error result. That should be fixed. :)

BTW. i was listing to this clip on my airpods, and noticed that ogvjs doesn't handle multichannel opus correctly either (i guess not totally surprising, we probably don't do any channel mapping, as that is a 'post codec' thing generally).

Looks like we should escalate this. Let's assign it at our meeting today.

Workaround seems to be doing the job; before creating the AudioContext, I have it create an <audio> with a short silent MP3 and force it to play. This seems to get the system audio mixer to see it as media instead of ringer, and the hardware ringer switch no longer disables the Web Audio output.

Yeah we just plum forgot to fix this. :) It's an irksome DoS vector though, so good to fix! Merged the patch to master; I'm leaving the branch patches until someone's ready to deploy.

*nod* latest rev is like this, seems sensible. i set the horizontal size cutoff for audio at 150px, could go tighter if we want.

Agreed. Latest patch rev shows only the duration for audio, and hides CC for short videos. Sound good or hide entirely on short (vertically) vids?

Ok, confirmed Safari likes 1 and 2-channel but not 5 or 6 (5.1) channel Opus.
It plays back a Vorbis 5.1 channel file but I don't know if the channel assignments or correct or anything (I have no suitable hardware).

Currently got something like this but the absolute positioning means the CC label and the duration label could overlap unless i give them more room. Also if placeholders can be made smaller we may need to exclude them.

(Poking this today)

Hrm, I hate having to replicate base browser behavior as workarounds lol. ;)

I think this is only a win if we're using aggressively high level stuff (high chroma subsampling, or 10-bit HDR) which we don't yet have any infrastructure for sensibly detecting and providing fallbacks for.

Yep, squashing from 5.1 channels to 2 channels resolves it. \o/

Ugh, even a newer transcode isn't running. Maybe it doesn't like the 5.1 audio?

Huh, I already did this in 2018: c6b601c4b

Confirmed; appears to be due to the second source file using high-resolution 4:4:4 chroma subsampling, which requires profile 1 on VP9 instead of the default profile 0 (limited to 4:2:0, which is usually the default).

(taking this)

I generally like the new experience, but the loading indicator appearing on the top of the page even for inline players looks a bit out of place. Couldn’t that also be shown inline, where the actual player will appear?

Should be quite easy to do this. :)

Do we do this with other modals in OOUI? Is there a best practice we should adhere to?

Resolving as fixed pending it turning out that these came back in larger numbers.

I just did a quick local test on current code, and using ffmpeg as the backing for thumbtime it does appear to work. Please re-open if it's still not working elsewhere and we'll try to diagnose!

Sorry, wrong bug!

Marking this resolved as nobody seems to be complaining in the last year and a half :D
