Youtube won't encode to OGG

Hi. I've found that many videos on YouTube have OGG stream available. But I can't get it, uploading my own video to the service. Compare the available streams for random video from YouTube and for my video:



Why does it happen? How to force OGG and HQ WebM encoding???

To my knowledge there isn't a way to force Youtube to encode to specific formats.  I do know they have changed their encoding standards many times,  so it's possible they had previously encoded to Ogg, but no longer use it for new uploads.

Also,  how long are you waiting after the upload before checking the formats that are available?  YouTube doesn't finish the encoding for all formats at the same time, some finish and become available before others.

YouTube does not use Ogg at all. Vorbis is used in WebM.

A difference between the two videos is that the Dayton Football-video is available in VP9/Media Source Extensions, whereas Test 4Kff is not. That is also why only ”WebM 360p” (with VP8) is listed. Popular videos/channels are prioritised for VP9-encoding.

So this takes place, well, thanks. But how much popular the channel have to be? Is there some documentation describing this terms?

I was going to test youtube audio encoding quality, and I found out that it uses something like FhG AAC for the audio stream. But then I was surprised that on other videos there are Vorbis streams also...

I haven’t seen any such documentation, it is only what people have noticed when using YouTube, see for example Doom9.

Just published my test video on youtube. Will try to get >1000 views. I see that on my channel most of popular videos has VP9 streams, but there are few videos with >1000 views but without VP9. It's strange... Looks like here is some random factor or something we don't know...

Anyway, now I'm sure thet popularity of the channel isn't enough.

Using youtube-dl, I got this list of available formats for https://www.youtube.com/watch?v=Z4C82eyhwgU

Using MKVToolNix, I created MKA-files from 171 and 43, and MediaInfo gives this information, identical for the two files:
Code: [Select]
File size                                : 2.22 MiB
Duration                                 : 2mn 26s
Overall bit rate mode                    : Variable
Overall bit rate                         : 127 Kbps

Exact sizes of the MKA-files:
43: 2 327 563 bytes
171: 2 327 575 bytes

Appears that identical settings were used for the two Vorbis-encodings.
