VSPipe

Synopsis

vspipe <script> <outfile> [options]

vspipe's main purpose is to evaluate VapourSynth scripts and output the frames to a file.

If outfile is a hyphen (-), vspipe will write to the standard output.

If outfile is a dot (.), vspipe will do everything as usual, except it will not write the video frames anywhere.

Options

-a, --arg key=value

Argument to pass to the script environment, it a key with this name and value (bytes typed) will be set in the globals dict

-s, --start N

Set output frame range (first frame)

-e, --end N

Set output frame range (last frame)

-o, --outputindex N

Select output index

-r, --requests N

Set number of concurrent frame requests

-c, --container <y4m/wav/w64>

Add headers for the specified format to the output

-t, --timecodes FILE

Write timecodes v2 file

-p, --progress

Print progress to stderr

--filter-time

Records the time spent in each filter and prints it out at the end of processing.

-i, --info

Show video info and exit

-g, --graph <simple/full>

Print output node filter graph in dot format to outfile and exit

-v, --version

Show version info and exit

Examples

Show script info:

vspipe --info script.vpy -

Write to stdout:

vspipe [options] script.vpy -

Request all frames but don't output them:

vspipe [options] script.vpy .

Write frames 5-100 to file:

vspipe --start 5 --end 100 script.vpy output.raw

Pipe to x264 and write timecodes file:

vspipe script.vpy - --y4m --timecodes timecodes.txt | x264 --demuxer y4m -o script.mkv -

Pass values to a script:

vspipe --arg deinterlace=yes --arg "message=fluffy kittens" script.vpy output.raw

AVFS

AV FileSystem is based on AVFS and shares most of its source code and functionality. This package has several uses. It can easily make a script file openable by any application, as it appears like a real, uncompressed avi file. It can also be used to bridge the 32/64 bit gap, since a plain file can always be read.

To use it simply run avfs in the core32 or core64 directories with the script name as argument. This will create a virtual file in C:\\Volumes.

The alt_output argument of set_output is respected and can be used to get additional compatibility with professional applications.

Avisynth Support

Note that this AVFS version is also compatible with Avisynth 2.6 and Avisynth+. When using Avisynth+ higher bitdepth output is also supported. The easiest way to obtain a recent version is to extract avfs.exe from the portable VapourSynth archives.
