=============================================== vsrawsource - Raw format reader for VapourSynth

raw(uncompressed) video source filter for VapourSynth. Also, YUV4MPEG2 and WindowsBitmap(24bit/32bit RGB) are supported.

Usage:

>>> import vapoursynth as vs
>>> core = vs.Core()
>>> core.std.LoadPlugin('vsrawsource.dll')
>>> clip = core.raws.Source('/path/to/file.raw')

If input file has alpha channel,
>>> clips = core.raws.Source('/path/to/file_with_alpha.raw', 1920, 1080, src_fmt='BGRA')
>>> base = clip[0] # RGB24 clip
>>> alpha = clip[1] # GRAY8 clip

options:

- **width**          video width (1~ default 720)
- **height**         video height (1~ default 480)
- **fpsnum**         framerate numerator (1~ default 30000)
- **fpsden**         framerate denominator (1~ default 1001)
- **sarnum**         sample aspect ratio numerator (0~ default 1)
- **sarden**         sample aspect ratio denominator (0~ default 1)
- **src_fmt**        color format of source video (default 'I420')
- **off_header**     offset to the first frame data (0~ default 0)
- **off_frame**      offset to the real data for every frame (0~ default 0)
- **rowbytes_align** byte alignment of all rows of frame (1~16 default 1)

these options will be ignored if source is YUV4MPEG2/WindowsBitmap.

supported color formats:

see format_list.txt.

Note:

When input video has alpha channel, this filter returns a list which has two clips.
clip[0] is base clip. clip[1] is alpha clip.

How to compile:

on unix system(include mingw/cygwin), type as follows::

$ git clone git://github.com/chikuzen/vsrawsource.git
$ cd ./vsrawsource
$ ./configure
$ make

if you want to use vs2015 then

- create a an empty dll
- add rawsource.c
