First of all, the board version is different. Mine (right) is 1.5, the one by @ascii211 (left) says 1.4. The one @eggrins got (image not supplied) has similar but not identical internals to either too, but in the end, the main chip is the same on all. contpic.twitter.com/c4xmsrAOse

Same as marcan's, mine reports 96kHz audio too. Similarly, it accepts 1080p in, and can only do UVC on 1080p at 5fps. I had to use MJPEG to get 30fps. full lsusb -v -d 534d:2109 output: https://lasagna.cat/i/4fcexoyj.txt  contpic.twitter.com/4p5P58ubCK

Some screen capture comparisons between a camlink 4k and "rullz". BTW, neither strips HDCP content (LOL). Test captures were at 1080p, rullz on YV12 (emulated), camlink on YUYV 4:2:2. Here's the x1 homepage, camlink on left, rullz on right. contpic.twitter.com/RyuHrFtjST

A capture of a dark scene. Neither are particularly good at capturing dark scenes, but there's a lot of artifacts on the rullz (even on YUYV 4:2:2). Raw: rullz: https://lasagna.cat/i/1bn2m0yp.png  camlink: https://lasagna.cat/i/wq8pgxb0.png  contpic.twitter.com/3oS119iuG1

Light scene. Both did quite well here (though rullz has worse colors) but if you zoom in, you can see that the rullz one isn't great with lines.

As 720p supposedly runs better (according to marcan's tweets), here's some comparisons of camlink and rullz in 720p. It does visually seem better in 720p to me too, not as good as camlink but still good.

One final comparison, in game capture, balanced light and dark environments. Raw: camlink yuyv: https://lasagna.cat/i/1hu32qd5.png  https://lasagna.cat/i/6bwcvk9d.png  rullz: https://lasagna.cat/i/uf2mannv.png  https://lasagna.cat/i/jmu4m13v.png  contpic.twitter.com/CcWhAHjJfZ
