I did some testing with VCS, embedding a http server into the code that exposes a web interface on the local network that you can access with a phone, tablet, whatever. It would route actions from the interface to the program, giving you basic remote controls for setting the current capture …

The alternative is to make it convenient for the user to make the switch. Keyboard shortcuts are obvious, but you could do audio triggers via microphone, read inputs from a foot pedal, use the phone as a remote, whatever's handy.

If we're only talking graphics vs text mode, how about training a neural net to detect whether it's looking at a DOS prompt? I'm thinking text mode is typically starkly contrasted with graphics, and the AI check can probably run in real time. Ok. Though, there is not "the text mode". You can train …

the resolution is just off and so it doesn't switch to the correct preset, so I manually have to set it to the correct resolution and then it picks the correct preset. If the wrong resolutions aren't random, you can try defining alias resolutions (Ctrl+A or something like that) so they'll be …

I made a quick web app for playing and corrupting Rally-Sport in the browser. Rally-Sport is a Finnish racing game from the mid-90s, and corrupting is the modifying of game asset files for entertaining or otherwise interesting results. The app comes with a selection of pre-made corruptions - i.e. …

I am running Datapath VisionAV capture with the VCS software and I just can't get proper colors. Everything is too dark. For instance in this screenshot the white color is rgb(239, 239, 239) instead of (255, 255, 255) and the blue widow bar is (0, 0, 112) instead of (0, 0, 128). With the original …

With a K6 300 (bottlenecking), I've seen temps reduced by up to 4 C load and idle by downclocking from 143 to 100 MHz, with 0-5% loss in performance up to 800 x 600 (tested in Quake 3, Need for Speed 5, 3DMark 99). So not a big reduction in temps, but also no clear benefit in running the card full …

Anyone ever encountered this and knows a solution? I've seen the same with a VisionRGB-E1S. I don't think the VisionRGB-PRO2 had the problem, but I can't remember for sure. It should be possible to fine-tune the positioning via the video card's control panel (if supported - Matrox at least should) …

This might be a stupid question but I'm trying to understand the aspect ratio setting: Capturing an input resolution of 640x400, is forced aspect ratio 4:3 and output resolution to 200% the same as setting aspect ratio to native and output resolution to 1067x800? It might be slightly slower with …
