== Description ==
Given an AviSynth script as input, '''avs2pipemod''' can send video, audio, or information of various types to [http://en.wikipedia.org/wiki/Standard_streams stdout] for consumption by command-line encoders or other tools. It is a continued development of [http://forum.doom9.org/showthread.php?t=160383 avs2pipe]. Thanks to Chris Beswick for releasing avs2pipe under [http://www.gnu.org/licenses/gpl-3.0.html GPL 3.0].

===Differences compared to the original:===
* Display total elapsed time.
* contents of 'info'
* New option 'benchmark'.
* New option 'trim'.
* New option 'x264raw'
* New option 'dumptxt'
* 'y4mp', 'y4mt', 'y4mb' and 'rawvideo' options instead of 'video'.
* FieldBased input will be corrected to framebased on yuv4mpeg2 output modes.
* Colorspace conversion that takes colormatrix and interlace into consideration.
* 'wav', 'extwav' and 'rawaudio' option instead of 'audio'.
* Convert bit depth function in audio output mode.
* Only the compilation with mingw/msys is supported.
<br>

== Requirements ==
* [http://sourceforge.net/projects/avisynth2/ AviSynth 2.6.0] or greater
* Supported color formats: [[Y8]], [[YV12]], [[YV16]], [[YV24]], [[YV411]]

== Usage ==
<pre>avs2pipemod  ver 1.3.0
built on Dec 19 2025 08:15:34

Usage: avs2pipemod [option] input.avs
  e.g. avs2pipemod -wav=24bit input.avs > output.wav
       avs2pipemod -y4mt=10:11 input.avs | x264 - --demuxer y4m -o tff.mkv
       avs2pipemod -rawvideo -trim=1000,0 input.avs > output.yuv

   -wav[=8bit|16bit|24bit|32bit|float  default unset]
        output wav format audio(WAVEFORMATEX) to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -extwav[=8bit|16bit|24bit|32bit|float  default unset]
        output wav extensible format audio(WAVEFORMATEXTENSIBLE) containing
        channel-mask to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -rawaudio[=8bit|16bit|24bit|32bit|float  default unset]
        output raw pcm audio(without any header) to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -y4mp[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as progressive.
   -y4mt[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as tff interlaced.
   -y4mb[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as bff interlaced.

   -rawvideo[=vflip default unset]
        output rawvideo(without any header) to stdout.

   -info  - output information about aviscript clip.

   -filters - output external plugin filters/functions list to stdout.

   -benchmark - do benchmark avs script, and output results to stdout.

   -dumptxt - dump pixel values as tab separated text to stdout.

   -dumpprops - dump frame properties as JSON string to stdout.

   -trim[=first_frame,last_frame  default 0,0]
        add Trim(first_frame,last_frame) to input script.
        in info, this option is ignored.

   -dll[=path to avisynth.dll  default "avisynth"]
        specify which avisynth.dll is used.

note1 : in yuv4mpeg2 output mode, RGB input that has 720pix height or more
        will be converted to YUV with Rec.709 coefficients instead of Rec.601.

note2 : in fact, it is a spec violation to use WAVEFORMATEX(-wav option)
        except 8bit/16bit PCM.
        however, there are some applications that accept such invalid files
        instead of supporting WAVEFORMATEXTENSIBLE.

note3 : speaker positions in files output by '-extwav' are set using
        the clip property from avs+.
        if it is not set, general speaker positions are used instead.
