I completely agree with this.

This would happen at the end of the filter graph. This patch is for
something in the middle. For a complex graph, I do not think there is an
easy way of implementing with just command-line tools. We would need
some kind of movie sink for that.

But this is way too specific to be accepted. Hard-coded URL parameters,
nothing to set the formats, not even the possibility of a filter that
changes the resolution. This is exactly what I was warning about in this

And do not let us forget that the coding style is not at all what we do.
