Hello,

There is a new twitch encoder for videos and vod downloading does not work for it,
I'm attaching the logs.
this is the vod I tried - https://www.twitch.tv/videos/2334138509

Technically, when watching live you see 1440p and 1080p available, but the vod only show 720p available. I think because the live stream up scaled with Nvidia partnership or something like that...

1440p and 1080p both 60 fps r in 265 (HEVC) now for select streamers who opted in for it (?)
in this case older browsers will show 720p60 in 264 (AVC) as the highest quality "transcode" so will the TD
(tho this is not true as 1080p60 HEVC/265 would be the highest quality transcode of the 1440p60 HEVC/265 source)

1440p and 1080p both 60 fps r in 265 (HEVC) now for select streamers who opted in for it (?) in this case older browsers will show 720p60 in 264 (AVC) as the highest quality "transcode" so will the TD (tho this is not true as 1080p60 HEVC/265 would be the highest quality transcode of the 1440p60 HEVC/265 source)

Twitch does not provide transcoding above 720. All streams with >1080 source that also have a 1080 option are being transcoded locally by the streamer. The 720, 480, 360, 160 resolutions are still being provided by Twitch though.

Sorry for the duplicate, didn't realize this was Av1 issue.
In any case, I still wonder why I can't even play the individual download files on my PC? I mean even if I directly download them from chrome network tab .

Because the video files are missing their headers. The M3U8 provides the header file name, which needs to be inserted at the beginning of every video file.
