That's what I was suspecting in the first place, that the video was uselessly decoded and then discarded when using a fakesink.
So I will definitely use the "flags" solution to disable the video. This is the right way to do it.

I'll have a look at that.

Thanks a lot, it seems to solve my issue (I'll check with some more videos, but it seems OK for the moment), and it also prevents the application from uselessly decoding video frames, and saves CPU. Great!...
