[gis4ever]

every time i try to open the .avs file this comes out

[*] AVI: Opening file "C:\Users\AM\Desktop\RRR.avs"

[E] Error: Avisynth open failure:

No combination of filters could be found to render the stream.

Audio returned: "DirectShowSource: couldn't open file

do you have haali media splitter + ffdshow installed?

for directshow to work, you need a working directshow splitter and decoder. What does graphstudio say when you render the file? do the pins connect?

on win7 you need win7dsfiltertweaker to enable ffdshow

or you could use ffmpegsource2 instead of directshowsource

Windows (DirectShow) doesn't natively know what MKV and MP4 files are. You need to install DirectShow file readers and splitters for Windows to access them. Haali will work for that. Then you need DirectShow decoders for whatever codecs are used in those files. ffdshow contains decoders for all common video codecs.

do you have haali media splitter + ffdshow installed?

yes i have.

and my operating system is
Windows Server 2008 R2

Have you enabled the appropriate decoders in ffdshow? Can WMP play the files in question? That would be the test that DirectShow filters are installed properly and working.

Also, if you are working in 64 bit Windows be aware that 32 bit programs require 32 bit codecs. 64 bit programs require 64 bit codecs. The two don't mix.

Have you enabled the appropriate decoders in ffdshow?

you go easy on me sir im a noob.

Can WMP play the files in question?

i don't have WMP, but it plays just fine on Media Player Classic

----
and im on 64-bit Windows

( i have installed them using K-Lite Codec Pack)

MPC has it's own file reader/splitters and many codecs built it. It doesn't have to rely on DirectShow installed filters. Try disabling all of them and see if you can play the files:

View -> Options -> Internal Filters... uncheck all the source filters and transform filters. Exit MPC and restart it for the changes to take effect.

You may want to note which are enabled so you can reenable them after testing.

[gis4ever]

did what u said but it still plays the file.

[poisondeathray]

Instead of fiddling with your directshow filters/splitter and trying to get them to work, you can use ffmpegsource2 as suggested above (alot easier, and more consistent, because directshow isn't necessarily frame accurate, and can vary from system to system depending on what filters you have installed)

[gis4ever]

okey I'II but tell me plz about installing ffmpegsource2, is all i have to do is coping the two files(ffms2.dll and FFMS2) to the Avisynth Plugin Directory, or what?

[poisondeathray]

yes copy the ffms2.dll and ffms2.avsi to the aivsynth\plugins directory

the syntax for both audio & video is

ffmpegsource2("video.mkv", atrack=-1)

or

vid=ffvideosource("video.mkv")
aud=ffaudiosource("video.mkv")
audiodub(vid,aud)
