To be fair the bitrate of the video is insane at ~5700 Mbit/s. The bitrate is so insane that you should really consider using an NVME drive for playback.

MPC-HC could kinda play it but only with extreme stutter and lag. My CPU (Ryzen 9 5900x) was completely maxed out.

I think you need hardware acceleration for a video like this.

Forget playback. How was that video file recorded? How do you even store data that fast, let alone encode it?

You can read more about why and how it was made here: https://www.svt.se/open/en/content/

The only place I could find where I could kinda play the video is inside Davinci resolve, but it doesn't look how I would like it to. Probably due to the apparent lack of HDR support in Resolve on Windows (unless you have a separate TV connected to the PC somehow.

Ohhhhhh. It's a video decoder torture test. "If your app can play this it can play anything" sort of deal. That makes sense.

Also makes sense that VLC puked.

I think it's more of a test for encoding, not sure if you are really supposed to try and play it in an app.

1 Terrabyte RAM with a 64GB RAM Drive perhaps?

Vlc has hardware acceleration afaik. I think its more a case of the ffmpeg codec not supporting it yet because what the actual fuck haha

Yeah, I think it's a good idea to try ffplay if VLC (or mpv) fail.

[–] lud@lemm.ee 2 points 1 year ago* (last edited 1 year ago)

I get similar results with ffplay compared to MPC-HC. I unfortunately haven't been able to get proper hardware acceleration to work anywhere.

Or maybe it does work and it's still bottlenecked by the CPU somehow.

Haha, that's fair 😂

JPEG2000 = not lossless

[–] lud@lemm.ee 10 points 1 year ago* (last edited 1 year ago) (1 children)

JPEG2000 supports both. That's why I specifically said that the video is lossless

[–] deadly4u@lemmy.ca 2 points 1 year ago

Right! Sorry, I assumed this was regular JPEG

Where can I try this

I downloaded "natural complexity" or something like that. Unfortunately FTP downloads are limited to 100 Mbit/s so downloads can take a while. Imo they should make a torrent.

Certain programs can do multithreaded downloads on ftp servers. Winscp is one that can do it. Idk about other software
