VirtualDub import MP4 no audio (error 00ff).

[SteveZ]

I have an MP4 video file that I have succeeded in importing using a downloaded MP4 plugin, but when trying to play it, I keep getting the error "No audio decompressor could be found to decompress the source audio format. (source format tag: 00ff)" I have K-Lite Mega Codec Pack, but have no idea what to do with it. I also am a little confused on how to install plugins for VDub, as it didn't come with a pre-created folder.

Any help would be greatly appreciated!

AAC cannot work in VirtualDub. If you find, download AAC decoder or convert AAC to WAV and use for external audio.

With MediaCoder or AudioCoder or another converter program can convert AAC to WAV...

[SteveZ]

So what would be my options as to import this video into VDub without/very little loss of quality?

[Hikmet]

Download and install FFMpeg and Directshow import plugins for VDub. And download "UT Video Codec" or "CamStudio Video Codec". This codecs lossless.

Use AudioCoder and Convert AAC video to PCM WAV format. Open VirtualDub, import video, after choose "Audio > Audio from other file" and select WAV file. After your works done in VDub, export video AVI format with lossless codecs and after encode MP4 this video. XmediaRecode is good program for encode videos.

I'm kind of a newb. If it's not too much trouble, could you give me a step by step tutorial just to get the video to work in VDub?

1.) Download 32-bit Vdub.

2.) Download FFMepg Input Plugin and DirectShow Input Plugin and install (Read "Readme" files).

3.) Download AudioCoder and install.

4.) Run AudioCoder, open MP4 File.

5.) Under "Audio" tab "Format > PCM" select and run "Start". Create WAV file.

6.) Open VirtualDub and open MP4 File.

7.) "Audio > Audio from other file..." and select WAV file. It's done

I really appreciate you helping me! Thank you so much! If I have a 64Bit system, will that make a difference? I've already got VDub 64Bit

32-bit plugins not work in 64-bit VDub and 64-bit plugins are less. 32-bit Vdub works in 64-bit system very well.

[SteveZ]

Thank you very much, it worked! I wish I could +rep you. However, my 193MB video will be 64GB after exporting to AVI. Is that normal?

I actually downloaded that and put it in the "plugins" folder that I had to create myself since there wasn't one in the 64Bit VDub download. It didn't work. However, I had to get another plugin to even import the MP4 video in question, which actually did work.

[Ai Haibara]

It's a 32-bit plugin, I believe, so it'll likely only work with the 32-bit version of VirtualDub.

This is not plugin, this is codec and only works under 32-bit OS...

[Ai Haibara]

That's what I get for keeping the VirtualDub/plugins discussion in mind.

I may have missed it but did you get an answer to the large file size you asked about? Most times you will have to set Video -> compression and possibly Audio -> compression to the VFW(video) codecs and ACM(Audio) codecs you have on your machine.

Video codecs will show up if VFW codecs are configured to use. If you have FFDShow or Klite installed, you set them to use under configuration -> VFW configuration.

A trick you can use when a file doesn't like your audio and refuses to play is just select Audio -> "Direct stream copy" and "Select from other file" and choose the input file again. It will use and copy the original audio.

NOTE: VirtualDub installs with just a plugins32 folder now and you can put all the plugins in it, both .vdf and .vdplugin plugins. You should find the Internal plugins (*.vdf) already installed in it.
NOTE: The FFInput and DshowInput decoders usually need to be manually selected by going to file, open, and drop down the type box and select them. They usually always work since ffinput uses FFMpeg to decode and dshowinput uses the directshow filters that Media Player would normally use. Just remember to set compression on video and audio or the file will be large.

Hope everything works well for you. I use VirtualDub a lot and have configured the beta version (1.10.3) to use ffmpeg in the external encoder feature so VirtualDub can save to FLV, Mpeg2, and MP4 as well as AVI now.
