how do i get the *.flv input plugin to work with virtualdub?

[snafubaby]

For some reason it is not working for me. Anyone have any suggestions? I have copied the FLVinput plugin to plugins32 folder. When I go to load an flv file into video dub, it gives an error saying 'unable to locate a video codec to decompress the video track.'. Any suggestions?

Use mediainfo to identify the codec in the flv and make sure you have it installed (ie if you can play it you have it installed - edit unless you play with vlc or mpchc which use their own internal codecs).

Secondly you can use the directshowsource option in the open dialog window of virtualdub to open just about any file type you can across.

Thanks for your help, Yoda313. I have a different problem. I used a different way to attempt to convert the .flv file. I used Freemake video converter, and played back the newly made file. The audio is very slow. I just need to increase the speed of the file. It's like playing an old 45rpm record at 33rpm speed. Could you suggest a way to increase the speed?

[yoda313]

I don't use that software so off hand I can't suggest anything.

HOwever I'm gonna take a guess if its a flv file its PROBABLY h264 and aac audio. Aac audio is pretty well supported these days (unless its 5.1 aac then you have problems if you want to playback the 5.1, it should auto downconvert to stereo on most if not all players that handle aac).

If it is aac and your destination player (be it hardware or software) can play aac than you should look for a "copy audio stream" option in freemake. Either that or some other phrase in the audio setup where you do not make any changes to the audio.

Virtualdub likes, or at least LIKED to use the older VFW (Video For Windows) codecs which are still available in FFDshow or K-Lite Megapack with FFDshow. That would mean downloading codec, setting FFDShow FLV VFW codec to enable, etc. If you found another way great. I'm not familiar with Freemake but just a suggestion. Make sure when you converted it didn't default the audio or even video to some rarely used like uncompressed or Indeo that may be using an old codec on your machine. This I have had happen a lot of times. Use MediaInfo before and after to be sure what you had and what ended up with.
Yoda313 hit it right on the nose in his posts. Just thought I'd add my 2 cents worth in case it helps.

Hi. Thanks for your help Budman and Yoda. The current problem i am having is that the original video is not loading into Virtualdub very well. The audio part, anyway. I checked the file with mediainfo, and it says the audio is 44.1KHz/22.05 KHz, 2 channels AAC (HE-AAC/LC) I did install the AAC codec, so i am wondering what is going on. When i try to play the video in V-dub, it's saying "No audio decompressor could be found to decompress the source audio format." Lemme know if you might know of a fix. Thanks!

aac acm

or use the ffinput driver instead of the flv plugin. It can open practically anything in vdub

If you can play in Media Player then you have the codecs to play installed. Make sure you install AVISynth because you can use it to play videos in VirtualDub with its scripts.

Create a text file with one line-- > Directshowsource("c:\<path>\<videoname.avi>) or mp4 or what ever actual video name is. Save as text with avs extension (anyname.avs). Drag that to virtualdub and it will load the video as if you drug the video instead and will use Windows Directshow filters normally used for Media Player. Everything else is the same as whatever you need to do.

I'll probably get chastised for this but whenever I get a new computer I install Avisynth, FFmpeg and the K-Lite codec pack. Everything like VirtualDub, Avanti, Avidemux, etc work fine after that. In your case, if you can play in Windows Media player then you most assuredly have the directshow filters installed and only need AVISynth installed to use the script method above.

I put a video on my website which you can watch to see it in use at Budmansite.com under the Virtualdub page.
Let me know if it works for you,
Thanks

Just checked mine and mine uses the ac3 filter 1.63 as shown below





I actually downloaded the AC3 1.63 filter and installed separate. Might try that one if you don't want to try AVISynth method.

UPDATE: I get the same no codec message with or without AC3 filter in Virtualdub so I tried the AVISynth method and works fine.

Thanks

Thanks again, Budman! I installed the aac filter and voila! The video loaded in fine.

The only issue i am having is with Freemake video converter. I initially used Freemake to try to convert this video, and that's when i ran into problems and decided to use virtualdub. Anyway, whenever i try to use that software to convert my video file to an .mpg file i can convert to a DVD, the audio gets slowed down to a crawl, like playing a 78rpm record on 33rpm speed. Got any ideas?

[Budman1]

I downloaded and installed freemake and converted to MPEG and DVD formats without the problem you're describing. If you use mediainfo on the VTS_01_1.vob file, what does it say for audio? Just wondered what is coded as. Also, do you have Any codec packs installed or generic Windows for the most part?
Thanks

What you didn't understand is that there are two audio systems under Windows: DirectShow and the older ACM. VirtualDub uses ACM. Media players use DirectShow. Installing a DirectShow AAC decoder allows media players to play AAC audio. But you need to install an ACM decoder for VirtualDub to access the audio.

This is analogous to the two video systems in Windows: DirectShow and the older VFW. Media players use DirectShow, VirtualDub uses VFW.

@snafubaby -

I don't think you mentioned that you were trying to make a dvd.

What we should have suggested knowing that was to simply use avstodvd in the beginning. It will read virtually any file you throw at it. You can create great customization with it and burn with imgburn aftwards to boot. (freeware fyi).

Edit - just to be clear you would input your original flv file, not any converted file after the fact.

Edit 2 - also avstodvd does both converting and authoring. It will encode to mpg internally with hcenc or quenc - those come installed when you install avstodvd.
