    I've recently changed my PC and re-installed everything but I couldn't find LWLibavVideoSource.dll anymore. Since it's needed to open various files (mostly .mkv for me) I'm wondering if someone can provide a link or pin a location where to find it. It's easy to find the other (LSMASHSource) but LWLibavVideoSource.dll not.

    Thanks everyone

  2. It's the same .dll for both functions (LSMASHSource.dll), there is no LWLibavVideoSource.dll

    Thanks for your reply poisondeathray.

    I'm using my old script (that worked for year)

    LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\LSMASHSource.dll")
    LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\TIVTC.dll")
    LwLibavVideoSource("C:\===Work===\01.mkv")
    TFM()
    TDecimate()

    and now I'm getting this message when I load it in VirtualDub (''File C:\===Work===\scripts3.avs does not have a video stream'')

    I'm getting it's a video codec problem ?

    Thanks for your help

  4. Can you open a simple script like
    Code:
    BlankClip()
    ?

    Are you using VirtualDub 32 bit or 64 bit?

  5. What video codec is used in your source file? I had LWlibavVideoSource() give a similar message with a VC-1 video recently.

    @ Sneaker: BlankClip() is working I can open that script. I'm using VirtualDub 32 bit

    @ jagabo: I tried different .mkv (VC-1 & Mpeg4) same result.

  7. Normally VirtualDub should display a proper error message coming from AviSynth. In VirtualDub go "File"->"Open Video File", select "AVIFile input driver" in the drop-down menu at the bottom and then select your .avs file. What is the error message?

    Note that LWlibavVideoSource() has certain dependencies depending on the binary (usually some version of Microsoft VC++ runtime package).

    @sneaker: I'm getting this message: ''Avisynch open failure: LoadPlugin: unable to load C:\Program Files (x86)\AviSynth\plugins\LSMASHSource.dll'', error=0xc1 (C:\===Work===\script3.avs, line 1)

    LSMASHSource.dll is in the \plugins dir.

  9. I think then you are either missing a dependency or are using wrong binary (not for 32 bit or not for AviSynth).
    Where exactly did you download the .dll? Try from here.

    As was mentioned by sneaker check to see if you have the VC redist package
    http://avisynth.nl/index.php/LSMASHSource#Requirements

    Make sure not to get 32 and 64 bit versions mixed up (error=0xc1)

    Ok, I deleted everything.

    Now I have avisynth 32 bit + L-SMASH-Works-r929-20170225-32bit (I only copied LSMASHSource.dll within the plugins dir.)

    Using basic script (to simply open .mkv)

    LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\LSMASHSource.dll")
    LwLibavVideoSource("C:\===Work===\01.mkv")


    Open the script using VirtualDub 1.10.4 (32 bit) and I'm getting the error: File "C:\===Work===\scripts4.avs does not have a video stream''

    (the .mkv file play well with VCL and Windows Media Player)

    @sneaker: I got the files from here: https://www.dropbox.com/sh/3i81ttxf028m1eh/AAABkQn4Y5w1k-toVhYLasmwa?dl=0
