Unable to open AVS in Avidemux

[videonyb]

Hi. I installed AVSproxyGUI for Avidemux.

But when I try to connect to it via Avidemux it shows error message:

Cannot find a demuxer for ::ADM_AVS_PROXY::

I get the same when AVSproxy automatically starts Avidemux after loading AVS file:

...
Initializing WinSock
WinSock ok
Binding on 127.0.0.1
Socket bound to port 9999
Waiting for client to connect...

> Exit Code: 0

What I do wrong?

Avisynth installed?

[videonyb]

Yeah. Avisynth 2.6, Avidemux 2.6

You may not have the source filters correct.

I've read that. I have all the recommended plugins...

OK.I install portable version with AVSproxyGUI also included and it works now, but...

When I try to save any video (loaded into avidemux via AVSproxyGUI) without re-encoding (Copy option for Video output) it shows another muxer error.

(if I load the video to avidemux directly then it works fine) :confused:

avisynth frameserves uncompressed video (and audio). You usually don't want to "copy" the stream

[videonyb]

It looks like avisynth and direct stream copying are incompatible.

Exactly.
The very first thing Avisynth does is to decompress video and audio, it only processes decompressed V & A. 'Direct Stream Copy' copies streams exactly as they are, ie compressed streams are copied without decompression.

EDIT: If you could do Direct Stream Copy on an avisynth source (input to some other program), then it would directly copy the
already avisynth decompressed Video and audio.

Yes, but you get same thing - uncompressed video

As soon as you touch avisynth, it gets decoded to uncompressed data

It's compatible with "stream copy" - if you mean uncompressed frames. Not the original stream compression. Vdub can do this, ffmpeg can do this etc.... There might be container limitations too (not all containers are suitable for uncompressed streams)
