 This may seem cumbersome but the idea of this source filter is to provide the actual encoded data without any colorspace conversions or resizes (these are usually really poor quality in other decoders).<br>
 AviSynth colorspace support is quite limited, fortunately most common JPEG formats are natively supported in AviSynth 2.6 (Y8, YV12, YV16, YV24 and YV411).

 == Description ==
 An advanced JPEG decoder for AviSynth 2.6 which decodes JPEGs directly in their native colorspace. It supports [http://en.wikipedia.org/wiki/Arithmetic_coding arithmetic] and [http://en.wikipedia.org/wiki/Huffman_coding Huffman] encoded JPEGs. In addition, JpegSource has an optional reconstruction pass that can only be done during the decoding stage. This process can accurately suppress common JPEG artifacts (blocking, ringing/mosquito noise, etc). The reconstruction pass is harmless on high quality JPEGs but can produce excellent results on highly compressed JPEGs. This technique yields better results than other post-processing methods.
