Hi! These are the files associated to the recording, both from the streams/1 and streams/hibernate folders:

(Also the viewer integrated into OM has 2 fps.) If I understand this correctly, then already the video stream output by the recording applet outputs broken flv. That's why I never believed this would be an ffmpeg issue.
