I would like to change speed of a video (i.e. changing fps) during playing by MIDI controller. How one can do it via Pure Data?

@Ajax.D If you want to load the video in pure data, have a look at the gem external and in particular the object [pix_film] which allows you to trigger the video frame-by-frame.
If you want Pd to control the speed of another video playback program, it depends on the program and which massages that program receives.

gem external

The first option. Thanks a lot! I do have a look.
