Hello,
I tried recording video by using the FFS internal feature. Only one format is proposed (h264) - I had a look in debugging tools but I have not found some specific settings -. FreeFLV player was able to read the first image and after there was a black display without any message. I tried with others players (VLC, ..) and the format was unknown. I tried also to record by using the W10 internal feature (W+ALT+R) which works very well for others sims: nothing ran.
Best regards
gerod
