Hello strk,

Yes, here's the code from video_stream_instance.cpp:

video_stream_instance::add_invalidated_bounds(InvalidatedRanges& ranges, 
        bool /*force*/)
        geometry::Range2d<float> bounds;

Yes, that must be the reason.

Same problem. I already used the URL printed by Gnash when it says
"Connection established to movie:"
Perhaps youtube recognizes Wget via UserAgent.
If you can download it yourself, just use ffmpeg command line tool to
convert the video to whatever other format and it will print the frame
rate among some other verbose information.
