Which external or library (GEM, PixelTango, ...) do you recommend me to process video?
PixelTango builds on top of Gem, so there is no realy difference here. (i don't think that PixelTango comes with an abstraction for Gem that does right out-of-the-box what you need)

You need one value for each pixel row in an image? That will probably require writing a custom external to do that.
not necessarily. if you have plenty of cpu left, you could go for Gem's [pix_dump], which dumps the entire image as a list into "pd-space". then you can do whatever you want with it (e.g. use iemmatrix to calculate what you need).
another solution with Gem might be to use [pix_resize] with a width of 1 and then [pix_dump] the image "column".
other libs: i am sure there are some simple resizing mechanisms in GridFlow. if you need to do more complicated stuff on the data, GridFlow might be a good choice anyhow, since you could stay in grid-space rather long and only do the conversion into pd-space at the very end.
pdp/pidip: i don't know, but i am sure there are solutions here too.
so it really depends on what else you want to acchieve. if it has to run on w32, then the solutions are limited. (but i don't know)
