Black screen with .MP4 in VirtualDub

[Toonyto]

Hello everybody,

I've installed K-Lite_Codec_Pack_670_Mega and I have installed the plugin to read .MP4 in virtual from this page : https://www.videohelp.com/tools/virtualdub. I put it in the Plugin folder of VirtualDub.

The problem is that it doesn't work. Thanks to the plugin I can open the video but the screen is black and when I push play the screen stay black even if it seems that the video is read. I tried it with Windows Vista 32bit and also with Windows 7 64bit and the problem is the same on both.

I've then installed the AMVapp pack (http://www.animemusicvideos.org/guides/avtech/amvapp.html). I tried also to create an .asv file with DirectShowSource("C:\mypath\myfile.mp4") in it, this open the video but the screen is green and when I push play VirtualDub crashes.

I have no idea how I can solve this problem, I would be very thanksfull if one of you could help me and explain me hox to do because I'm beginner in video processing or codec managment.

Thanks you in advance

Moving you to our editing section. Did you try the directshow plugin http://forums.virtualdub.org/index.php?act=ST&f=7&t=15093&st=0 ?

1) install avisynth

2) download ffmpegsource2 plugin, unzip to avisynth/plugins directory (especially the .dll and .exe)
http://code.google.com/p/ffmpegsource/

3) create a script: open a .txt file in notepad in the same directory as video, change the filenames/paths to match, save it, change extension from .txt to .avs

aud=ffaudiosource("video.mp4")
vid=ffvideosource("video.mp4")
audiodub(vid,aud)

4) open .avs in vdub

download ffmpegsource2 plugin, unzip to avisynth/plugins directory (especially the .dll and .exe)

You don't need the .exe (for most purposes).
ffmsindex.exe is a standalone program for creating indexes.
It is not needed for indexing invoked from an Avisynth script (via the ffvideoSource, ffAudioSource or ffIndex commands).

Thank you for your advices.
After installing the last version of Avisynth I tried the script :

aud=ffaudiosource("Z.mp4")
vid=ffvideosource("Z.mp4")
audiodub(vid,aud)

but it doesn't work and gives me this error :

Avisynth open failure:
FFIndex: Failed to open 'c:\Z.mp4.ffindex' for writing
(C:\Z.avs, line 1)

Do you know what can be the problem ?


Then, I tried again the script :

Directshowsource("C:\Z.MP4")

This didn't work before I tried what you advised me but now it's working ! The picture stops sometimes but at least I could open it. It seems that it's the installation of the last version of Avisynth which made it working.


Anyway if you have an idea of what could be the problem with the other script [aud=ffaudiosource("Z.mp4")/vid=ffvideosource("Z.mp4")/audiodub(vid,aud)] and what does the error message means i'm interested in it because I would like to understand this problem.

[Gavino]

Looks like it is failing to create the index file.
Do you have write access to "C:\"?
Which version of ffms2 are you using?
It's odd that the error message mentions FFIndex (rather than FFAudioSource or FFVideoSource), since you don't call that in your script.

The MP4 plugin in that link is broken and the author dropped support long ago. You need to use the quicktime input plugin instead.

Maybe try VFW configuration in ffdshow and enable support for MP41, MP42, MP43 and maybe Other MPEG4 (MP4S, M4S2)

...Or try with old MS MPEG-4 VKI codecs.

Hello, sorry that I couldn't answer before. Thank you very much for your replies, it's working, I can play MP4 format. It is still quite unstable but it's working.
Thanks.
