While I could always use ant video to capture a streaming video, Win8, newest AntV and Mozilla FFox versions, now it will not recognize any site's video's playing at all. Anyone have any idea what to check? I reset FF and got a new AV add-on, to no avail. Made no other major program changes. Can uTorrent be interfering with it (but it is rarely if ever open or on)? Any advice/help/suggestions are greatly appreciated.
I had the same issue and found this article that explained why it stopped working and how to fix. https://support.ant.com/hc/en-us/articles/115000513446-Firefox-51-Multi-Process After changing the setting AVD is working again.
