This thread shall begin much like one of my previous ones...

One day I got bored (again) and thought it would nice to have a plugin to open mkvs and similar things. That attempt failed miserably because it turns out that ffmpeg has just as much documentation as the average open source project.

But as you all know you can't let computers win. Ever.

This plugin should support decoding of all FFmpeg supported video formats with frame accurate seeking in avi, mkv and mp4 and possibly some others. Haali's parser is used for matroska since the ffmpeg one has serious issues and FFmpeg for everything else. Opening files is however a bit slow due to the required indexing.

Note: The real name is "Fabulous FM Source 2" and is in no way related to FFmpeg.

How to use as an image source in VapourSynth:
import vapoursynth as vs

first_image = 4
num_images = 160
filename_pattern = 'D:/imgseq/output_{0:05d}.jpg'

c = vs.get_core()
placeholder_clip = c.std.BlankClip(clip=c.ffms2.Source(filename_pattern.format(first_image), cache=False), length=num_images)
def image_loader(n):
    return c.ffms2.Source(filename_pattern.format(n + first_image), cache=False)[0]
clip = c.std.FrameEval(placeholder_clip, image_loader)
