I'm trying to capture the preview feed off of my a590 and although I know it's not possible with something like gPhoto using the cannon api, I keep reading things about ptpcam, and now something about chdkcam. I installed ptpcam (on linux, but I also have windows) but I couldn't find out how to grab the video. Then I read something about chdkcam, but all the documentation on any of this amounts to developers in 24-page forum threads discussing their current issue. The wiki for chdkcam and googling "chdkcam download" certainly doesn't yield any info. So my questions are:
1) Can someone tell me if it is even possible to do capture the feed in this way and point me to any instructions if it is?
2) Where do I download chdkcam to even test it?
Thank you for the great project!
