AvsProxy/VapourSynth proxy

Avisynth is a powerful scripting language with plenty of plugins. The sad thing is that it is only available on Windows. More info at avisynth2.sf.net.

AvsProxy is a small executable meant to be run on Windows or under Wine. It is to be compiled with Microsoft Visual C++ tools as Avisynth is C++. GNU C++ does not like VC++ at all. The good news is that Microsoft has a free version of VC++ called Visual Studio Express.

AvsProxy, as the name says, is a proxy between Avisynth and Avidemux. It will ask Avisynth frames and make them available on a socket interface so that Avidemux can read them.

The syntax is simply

avsproxy foo.avs

or

wine avsproxy.exe foo.avs (if you are running Wine)

Note:

• It works as well under 32 bits or 64 bits Linux, with 32 bits or 64 bits Avidemux, SMP or not.
• If you have error starting AvsProxy, it means either your Avisynth or Avisynth-under-Wine installation is incomplete.

Once you have started AvsProxy, it is waiting on its socket to receive commands. Now we have to make Avidemux aware that it must read over that socket.

There are two ways to do it

• Using a fake script. It must contain “ADAP” as first line, add a few lines of text afterward

ADAP

lkmlfdkmdlkdmlkdmflfkmkfmfdlkmflkfdmldkf

• Using File→Connect to AvsProxy menu entry

Now avidemux connects after reading the fake file…

This example is done on a 64 bits SMP system, and it works without problem.

Avisynth Proxy GUI for Windows(nbsp)(ndash) a graphical user interface for AvsProxy written by LoRd_MuldeR

VapourSynth is the next gen version of AviSynth. As a bonus, it is natively multiplatform. As for Avisynth, a small proxy used, but this time there is a native GUI for it : vsProxy_gui.

Select the .vs file, and then click run.

VSProxy is using the same internals as AVSProxy, so as far as avidemux itself is concerned, VSPRoxy = AVSProxy.

On the avidemux side, select File→connect to avsproxy and you are good to go.
