I think this will change. Nvidia hired devs on Nouveau, NVK is coming along, etc

Some of it probably comes from other companies that are unable or unwilling to relicense it even if Nvidia wanted to
Looks like the birdie has escaped phoronix…
In the small chance that this comment is serious, Nvidia is found this because the corporate server-based customers need the ability to troubleshoot and debug the driver.
The actual trade secrets are being moved into the proprietary firmware blob and out of the driver.
PNG is a rather slow algorithm based on the DEFLATE compression from zip/gzip. You could extract to bmp or some other uncompressed format. First, to ensure it is lossless, make sure it supports the video’s pix_fmt without needing conversion.
I have a 5900x (zen3), and apparently I got a bit unlucky with the silicon and ended up with a CPU that’s slightly unstable at its stock voltages and stock boost clock. The system would freeze and reboot randomly, and the bios would report an MCE error. This crash could be reproduced with near 100% success by doing sha1 hashing specifically for some odd reason. This is not a Linux issue, it’s a hardware defect.
It may be an Asus motherboard specific thing, but I found a workaround by going to the bios settings, precision boost overdrive, and increasing the voltage scalar to like 7. Now it’s been two years and I have only ever had it happen once since I changed that, so I’m happy.
I already force Wayland global for SDL games because the xwayland one has a horrible stutter while the native Wayland works flawlessly. Making it the default sounds reasonable to me. If specific programs don’t work with it, they can override it
Ratios that extreme would probably only be seen in cases where the source video was really poorly compressed anyway, which is what the commenter probably experienced. I’ve had that happen before too. Expect more like half the size compared to H264, which is still pretty good
At its highest compression setting (zstd -T0 -19 --long
), it’s about the same as lzma in compression ratio (varies a bit from file to file though), but slightly faster to compress, and much much faster to decompress. Decompression speed is not significantly affected by the compression setting (though compression speed is) and is usually at least a few hundred MiB/s to 1G+
Please do not use exfat on anything critical. It is slow as hell, it does not have journal or CoW to ensure consistency on unintended shutdown, and is designed to be extremely simple to implement, not robust. Good for flash drives and sd cards, but not normal storage.
