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.

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.
