I just discovered something that VLC REALLY didn’t like to play. A 4K50fps JPEG2000 YUV444 12bit lossless ~48 GB video that was only 1 minute long.
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.
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.
Yeah I could definitely see this for slo-mo and data recording in an actual laboratory setting that requires it to be as accurate as humanly possible. Idk if this is a standard though I’m not a scientist.
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.

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

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.
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 😂

It’s basically intended to test encoding and stuff like that.
Maybe some kind of super slow motion high resolution type thing?

JPEG2000 = not lossless
JPEG2000 supports both. That’s why I specifically said that the video is lossless

Right! Sorry, I assumed this was regular JPEG
Where can I try this

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