[Numpy-discussion] out parameter for np.fromfile

I was wondering what would your thoughts be on adding an output parameter to np.fromfile? The advantage would be when interfacing with executables like ffmpeg which are arguably easier to use by calling them as a subprocess compared to a shared library in python. Having the output parameter in np.fromfile would enable pre-allocation of large arrays that are reused during the computation of new image frames when decoding large video files. Thoughts are appreciated! Mark
