how to create a virtual file linked to the a real .avi video file ?

[marcorocchini]

Hi cats,

please I need to creare a virtual link-file to another real .avi video file.

For example if I have c:\myvideofile.avi

I need to have a "fake" myvideofile.avi also in v:\cats\

so that I have: v:\cats\myvideofile.avi that point to c:\myvideofile.avi

is it possibile this? also in windows XP?

and, if possible, the fake v:\cats\myvideofile.avi have to disappear if the source c:\myvideofile.avi does not jet exist

thanks

Right click drag/drop, select Create Shortcut Here.

but it's a .lnk and not a .avi

Symbolic link guide

Come down to "Symbolic Link with Vista and Windows7/8/10" then below "Enumeration of Hard links" and read text about xp below the picture.

Very time consuming.

And no to the second part ... you will definitively cause system problems.

mmmmm yes however I need this to read only a .avi file, not for write

Why, if I may ask?
You use batch scripts where making a path as a variable is not a problem. So why do you need that? I'm asking because this looks like wrong question/workflow, sort of.

IIRC old versions of avfs placed the dummy file in the same location of the avs. For sure they worked with XP

So if actual video was in "c:\" directory , but your avs was in "d:\dogs\are\better\than\cats\" directory, the fake AVI would also be in "d:\dogs\are\better\than\cats\" directory

Newer versions place it in c:\volumes and I don't think you can change the location . You might have to experiment and find a matching version of pismo mount

[marcorocchini]

I have try the pismo version 1.66 as older version, but for example if my .avs script is in d:\dogs\are (so that d:\dogs\are\me.avs) the pismo/avs system create a folder in "are" called me.avs and the result is: d:\dogs\are\me.avs\me.avi

but I'm a cat

Possibly I would like have the same .avi in the same folder

[poisondeathray]

Actually on old XP versions it creates a subfolder with the avs name

e.g.

"d:\dogs\are\better\than\cats\dogs.avs" will create a subfolder dogs.avs with dogs.avi inside (plus any audio tracks as wav), so full path looks like

"d:\dogs\are\better\than\cats\dogs.avs\dogs.av i"

EDIT: Oops I didn't see your post . I don't think you can specify/change the location on the old versions either

[poisondeathray]

Or another one was ffdshow's avstoavi . Old versions had it, I don't think newer versions have it anymore. I think it created the fake AVI in the same directory. It wasn't as reliable as avfs, however (the fake AVI didn't work in all programs, but the fake AVI made by avfs works with everything)

And _Al_ has a good question, why are you doing this ?

[Cornucopia]

No, no. Just use SUBST!

SUBST V: "D:\DOGS\ARE\BETTER\THAN\CATS\DOGS.AVS\"

And use V:\dogs.avi...

To delete virtual/subst drive,

SUBST V: /D

mmm I think to "solve" the problem using this subroutine and mklink.exe:

:Make_File_HD2HDinterlace <VCF_FILENAME> <AVS_FILENAME> <FILENAME> <ORG_FILENAME>

pfm unmount "%~n1_HDavs.avs"
     
         v:\automazioneclip\core\ffmpeg.exe  -n -i %4 -filter_complex "[0:1] [0:2] amerge,volume=%AudioVolume%" -c:a pcm_s16le "%DestFolder%\%~n1_HDavs.wav"
         rem v:\automazioneclip\core\ffmpeg.exe  -n -i %4 -filter_complex "[0:3] [0:4] amerge,volume=%AudioVolume%" -c:a pcm_s16le "%DestFolder%\%~n1_HDch3ch4avs.wav"

        rem ***Make The .avs Script File ***
        echo SetMemoryMax^(%SetMemoryMaxValue%^)>"%~n1_HDavs.avs"
        rem echo Import^("v:\automazioneclip\avisynth\plugins\IResize.avsi"^)>>"%~n1_HDavs.avs"
        echo LoadPlugin^("v:\automazioneclip\avisynth\plugins\LSMASHSource.dll"^)>>"%~n1_HDavs.avs"
        echo LWLibavVideoSource^(%4^)>>"%~n1_HDavs.avs"
        echo #colorMatrix^(mode="Rec.601->Rec.709"^)>>"%~n1_HDavs.avs"
        echo #ColorYUV^(levels="PC->TV"^)>>"%~n1_HDavs.avs"
        echo #ColorYUV^(gamma_y=-7, gamma_u=-7, gamma_v=-7^)>>"%~n1_HDavs.avs"     
        echo AssumeFPS^(25^)>>"%~n1_HDavs.avs"

        IF "%visualDeinterlace%"=="1" echo bob^(^).SelectEven^(^)>>"%~n1_HDavs.avs"

        echo #usa_1_Make_File_HD2HDinterlace>>"%~n1_HDavs.avs"
       
       del "%~dp1%~n1_blank.wav"
       del "%~dp1%~n1_blank.avs"
       rem del "%~n1_HDavs.avs"

       
       pfm mount "%~n1_HDavs.avs"

          for /f delims^=^" %%a in ('pfm flush "%~dp1%~n1_HDavs.avs"') do set "flushed1=%%a"
          set "flushed=%flushed1%\%~n1_HDavs.avi"
          del "%~dp1%~n1_HDavs.avi"
          v:\automazioneclip\core\mklink.exe /s "%~dp1%~n1_HDavs.avi" "%flushed%"
  
 goto :eof

it create a fake .avi file that point to c:\volumes\%file%.avs\%file%.avi

I use it to "feed" the catRazor NLE directly the mxf files without transcoding into .avi mjpeg

I didn't know NTFS supported POSIX-like symbolic links. Apparently they've been available since Windows Vista.

I tested the script also in windows xp and seems work well
