I recently found the libpd library which can be used when developing applications for Android. As I have understood, it can be used for example music related projects where low latency is required.
My question is if the library can be used with video as well? I need several video clips to be able to, on various Android devices, play simultaneously with as low latency as possible.

the short answer is "no".
libpd encapsulates the audio (and message) domain of "Pure Data".
for video, you will most likely be better of using a native solution.
(afaik, none of the graphics externals for Pd has been ported to android yet).
