Description

An advanced JPEG decoder for AviSynth 2.6.

Limitations

JpegSource does not support the following:

• YUV440 JPEGs (AviSynth does not support this colorspace)
• CMYK/YCCK JPEGs
• JPEGs with arithmetic compression

RGB encoded images are supported, but AviSynth does not support planar RGB so there's a work around to correctly display RGB JPEGs.

See the examples below.

Requirements:

- AviSynth 2.6.0 Alpha5 or later

- Supported color formats: Y8, YV12, YV16, YV24, YV411

- SSSE3 capable CPU

Syntax and Parameters

JpegSource (string file, int "rec", int "length", float "fps_num", int "fps_den")

string  file =

Path to image file. Path can be omitted if the script is in the same folder as the image file.

int  rec = 1

Number of reconstruction passes.

int  length = 1000

Clip length in frames.

float  fps_num = 24

FPS numerator.

int  fps_den = 1

FPS denominator.

Examples

JpegSource with default settings:

JpegSource("image.jpg", rec=1, length=1000, fps_num=24, fps_den=1)

Correctly display an RGB encoded JPEG:

JpegSource("RGBimage.jpg")
MergeRGB(last, UToY8(), VToY8(), "RGB24")
