This filter loads raw video data.
RawSource (string filename, int width, int height, string
pixel_type, int "offset")
filename: the raw file e.g. a YUV-file.
width = 720, height = 576: you must specify the image dimensions. width is max 2880.
pixel_type = "YUY2": the type of the raw data. An appropriate mapping to AviSynth's internal data is done. Supported types: RGB, RGBA, BGR, BGRA, YUYV, UYUV, YV12, I420.
offset = 0: constant header offset.
The framerate is fixed to 25fps, you can change it with AssumeFPS, if you need (e.g. for NTSC-material).
If a YUV4MPEG2-header is found, width/height/framerate/pixeltype is set according to the header data. Only fixed-length FRAME headers are supported. Note that YUV4MPEG2 is raw video with a header (avsyuv outputs it for example).
LoadPlugin("c:\myprojects\rawsource\release\rawsource.dll") RawSource("d:\blue_sky.yuv", 1920, 1080, "YV12") bilinearresize(352, 288) # raw UYVY file with and offset of 1024: RawSource("c:\video\test2.2vuy", 720, 304, "UYVY", offset=4*256) # uncompressed mov with an offset of 48: RawSource("x:\uncompressed_yuv_no_audio_720x486.mov", 720, 486,"UYVY", offset=48)
Here's a link which contains avi2yuv, which can be used to make raw yuv files. You need to feed it with uncompressed RGB files, otherwise it doesn't work.
