Errors opening .avs for conversion

[Parypv]

Hey
I posted a thread here earlier and wanted to convert an mp4 with x264 vudeo, aac audio to xvid avi mp3 vbr 128kbps
i managed to succesfully convert the xvid avi
though the audio gave me problems - in another thread.
but now i'm trying to convert more of my vids so that i'm left with just vids no audio (so i can do all my audio at once and i have a complete vid)
i haven't messed about with my avs' , i've left them alone since they last worked, but for some reason when i open them with VDub (as i've always been doing when it has been working) i get an error saying ..:-
AVISynth open failure
DirectShowSource: the filter graph manager won't talk to me
xxxx, line 1.

Any ideas?

Thanks
Parypv

can you play the mp4 with wmp without any problems?

[Parypv]

Yh I always have been able to play them without any problems
Though there is one thing..recently when i was converting to xvid with vdub the pc sort of crashed in the middle of a convert..so i had to manually restart by "pressing the reset button"
could this have messed something up?
also when i play any mp4 now i get a green bar at the bottom??
though when i play it with quicktime player it's fine..
probably the player..though i don't know what this error is all about..because i need to sort my video out (which was easy before this erro) it's the audio that is unexpectadly giving me errors (see https://forum.videohelp.com/viewtopic.php?t=310528)

Thanks Baldrick

If you use

DirectShowSource("path to avi", false) does the script work ?

The false parameter tells avisynth to ignore the audio when loading. If this works, you know you still don't have the right audio codec.

[Parypv]

Nope. Doesn't work
I don't get why it would stop working all of a sudden. I could open my mp4's in vdub before and convert them..
Now i can't open the avs' in vdub - even though i haven't touched the avs'.
VDub is still the same as is the mp4's and the avs'.
Don't know why/how the errors came up when it was fine before..

Thanks

why don't you remove completely your AVISYNTH from your computer : in control panel/add remove programs, and the AVISYNTH's folder, and then reinstall AVISYNTH 2.5.7 RC1 version ?

maybe your DirectShowSource.dll is corrupt, or something

[Parypv]

Thanks for the suggestion but i'm still getting errors
Still have audio to figure out too.
Video converted perfectly before with the avs script..

Also just one more thing i need to add.
If i want to keep the resolution (fullscreen) the same from my source to the output, the ni'm sure there's no need for me to put LanczosResize as i've been told to do ??!
However though that is there, my output still seems to be in the same resolution so i don't know what that'll actually do...(LanczosResize)

[Abond]

Could you post the avs script,please?

[Parypv]

yep
here it is,

directshowsource("fullpathtomp4here", audio=false)
LanczosResize(640,480)

do i need LanczosResize if i want to keep the resolution as it is..

Thanks - i never got this error message before so i'm not sure whether if it is the script.
I've tried uninstallaing/reinstalling avi synth too..no luck

Many Thanks

do i need LanczosResize if i want to keep the resolution as it is

No.

[Parypv]

k then i'm getting rid of that - don't see the point of having it if i want to keep the original resolution.

Thanks GunS1inger

Now the avs is even more simpler - ...still won't open..same error

DirectShowSource: the filter graph manager won't talk to me

[Parypv]

Any ideas on what i can do.
I really need the help

Thanks guys

I assume that:

directshowsource("fullpathtomp4here", audio=false)

isn't the literal script, but that the path is accurately written.

Otherwise, never had the error, never seen the message. Try the AviSynth Forum at Doom9, where the AviSynth developers and most expert users hang out.

[Parypv]

yep the path is written..but the really crazy thing is that this error never came up before!
i was converting with that avs script fine earlier..then i tried again to get different results and i couldn't even open it!
Please guys this is really confusing me - what should i do?
could it be because i restarted my pc (from it freezing) from the "box" manually? - while it was converting
though nothing opens this up - vdub or vdubmod.
i've tried reinstalling avi synth
also tried saving in another location etc.
but if a proper error message is coming up it must be an "official problem"
"filter graph manager wont talk to me?"
what does that mean
maybe there's something wrong with my mp4 (which i doubt because i was converting fine before before this error came up - and i didn't touch the avs to make all this happen?!"

Thanks guys for the help

Happy reading.

Many thanks GunS1inger, will have a read

[Parypv]

Thanks GunS1inger!
All i had to do was re-install my codecs..i thought that was the problem...

Now i can go back to encoding the video - and the site you gave might have a solution to my audio problem
If not i'll be back!

Thanks again!

Parypv :P
