It does a deblocking of the picture, using the deblocking filter of h264. Ported from AviSynth plugin http://www.avisynth.nl/users/fizick/mvtools/deblock.html
deblock.Deblock(clip clip[, int quant=25, int aoffset=0, int boffset=0, int planes])
clip: Clip to process. Any planar format with either integer sample type of 8-16 bit depth or float sample type of 32 bit depth is supported.
quant: The higher the quant, the stronger the deblocking. It can range from 0 to 60.
aoffset: Quant modifier to the blocking detector threshold. Setting it higher means than more edges will deblocked.
boffset: Another quant modifier, for block detecting and for deblocking's strength. There again, the higher, the stronger.
planes: A list of the planes to process. By default all planes are processed.
aoffset is inferior to 16, the filter does nothing at all. The same goes for
