[PD] recording GEM output weird framerate

@ Lazzaro: yes I know, thanks for specifying, but the problem is that the
duration of audio and video files I record don't match each other.
@ Cirylle: ok, now maybe I understand.
I'm actually already using a similar abstraction of yours to monitor fps :)
My patch is completely automatic, it's a sonification/visualization of large
amount of data, thus I just press a toggle to start it.
if while recording the fps monitor shows 10fps, it means that also pix_write
will record only 10 frames per second and _not_ 20 as I stated in gemwin, is
I was probably wrong assuming that whatever fps is stated in gemwin will be
the recorded fps, even though the machine can't reproduce it in real-time.
Ok, so, if I can only record at 10 fps, what do you suggest to finally have
a recorded video with a decent framerate? (apart from changing machine...)
I guess I could use ffmpeg to double the framerate, but the video might be
