Error frame 0 in VirtualDubMod

[rocky12]

Why do I get error frame 0 in VirtualDubMod when I open up the video? What does it mean?

Something about B frame decoder lag? The video doesn't start with an I frame. Just skip the first frame or two.

Yesterday I tried skipping more then two frames. I still get errorr decoding..

Install Avisynth and FFDShow. Create a simple avisynth script in notepad that says

DirectShowSource("pathtoyourvideo/videoname.avi")

and load this script into virtualdub instead.

I keep getting open failure. Is my script right. I'm tring to use VirtualDub to DeMux audio from video. I rather use virtualdub, or mod.

DirectShowSource("G:\Running Scared (2006).avi")

Is your video indeed stored in the root directory of drive G?

I suspect, though, it's a problem with the filename (especially the parentheses). Try renaming the AVI (or just copy it) to a filename without spaces and parentheses, then use that filename in the AVISynth script and see if it works.

Do you have AviSynth installed? You need that to use DirectShowSource().

If you use VirtualDubMod you can get it to generate the AviSynth script for you. This prevents typos and makes the process a little easier. Start VirtualDubMod then select File -> Open Video File. At the bottom of the open file dialog there is a pulldown labeled "Use AviSynth Template". Select DirectShowSource. Then select your video file as usual. An AVS script will be created in the same folder as the video and it will be opened automatically. In the future (if you close VirtualDubMod and restart it) you can open the AVS script directly.

I don't understand. When I open the video directly, I get error frame 0.

You really have to help us out here. Exactly what error message do you get? Is it only the first frame or does it persist through the entire video?

Using AviSynth's DirectShowSource might behave differently than opening the video directly in VirtualDub because DirectShowSource uses Windows' DirectShow system to read and decompress the video. Opening the file directly uses VirtualDub's internal file reader/splitter and Windows' VFW (Video For Windows) library to decompress frames. VFW is an older, more primitive, less capable video handling system.

Thank you. I got it to work. I made a thread in audio.
