In recent days and weeks there have been strange issues randomly reported regarding FlashyWrappers. Even for people with working FlashyWrappers, they started to report recording not working after few frames. Unfortunately, this turned out to be a problem in Flash Player 16+ breaking the technology being used to build FlashyWrappers. This technology was abandoned by Adobe almost right after it was released. It is being maintained by the community now and workarounds are being created.
The issue shows up only when using FlashyWrappers in multithreaded mode in Flash Player, because that’s where the issue originates. All native builds for AIR are using native threading and therefore shouldn’t be affected.
See this thread for details & progress: https://github.com/crossbridge-community/crossbridge/issues/77
The issue seems solvable even there might be some speed tradeoffs. It might still take some time to come up with the final solution and then also to rebuild FlashyWrappers for Flash Player with patched Crossbridge.
