@tateu: Wow, great job  . Works great on the files I tried, except for the ones I didn't have a decompressor for. Maybe you could show the FourCC in the "Could not init VFW" error message so we know which decompressor to look for. It's really cool that VirtualDub can open all these formats now .
EDIT: Ah nice, I was able to switch to mode=0 to open the file and see the file information. It's Sorenson Video 3 which I found in ffdshow and enabled so now it works in mode=-1. |

FLV Input Driver [EDIT: Updated link]
I implemented TimeToPositionVBR/PositionToTimeVBR based on the audio tag timestamps. It seems to work pretty well, maybe I'll just leave it like this, but I'm not sure yet. Also, PCM audio might work with this version, but I don't have a FLV file to test it with (only have one .flv with PCM but there's no video stream). The synch in most files is pretty good now. I did spot one file that was quite a bit off but it isn't a problem with the audio, rather because the framerate of the video was variable.
EDIT: I should warn everyone, it's a bad idea to direct stream copy the MP3 audio into an AVI. It doesn't play correctly in most players, maybe because the MP3 frames are split across the AVI chunks or something, I'm not sure.
Also if you just want to extract the MP3 without decompression, you might think to File > Save WAV and strip off the RIFF headers, but I don't recommend this because the end may be slightly truncated (I think this would be fixed by using ceil instead of rounding nAvgBytesPerSec, I'll consider doing that). Instead, I recommend FLV Extract.
EDIT2: I'm thinking about how to handle variable framerate videos because a handful of the FLVs I saved from YouTube are like this. I could pad gaps of missing frames with drop frames, it might not be too hard. |

I've uploaded a new build of my WMV plugin, which adds experimental support for loading WMA files (audio only):

Moitah, you're right, it should display the required codec info if it fails. In auto mode, I think it should fall back to using Quicktime API's if VFW fails. Otherwise, it's not much of an auto mode.
Hmm...I though I had checked what happens when you preview quicktime video in one of the filters, such as sharpen...I guess I didn't. In RGB24 & RGB32, the preview displays upside down, in YUY2 it is scrambled and in YV12 it crashes. I guess I'll have to fix that. |

It's just another video container...Open Media Framework Interchange. It's the standard format that Avid's capture to. At work, we switched to an Avid editing system a few years ago; we had previously been using Avi based systems. The switch to an Avid was the reason I started working on Quicktime and OMF file import, in the first place. |

This is really great what is happening. I wish to thank you to all!
phaeron, could it be possible to expand this approach for support of output plug-ins as well?
fccHandler, how about a support for loading of successive VOB files in one go? |

Kewl.
I have VP6 decoder installed, and some players show these (like GOM).
I don't know what these have eaten, but yes, have some:

http://www.loadusfx.net/storm.flv
If these work at your end then my decoders are screwed up. ;D

DirectShow decoder?
GOM Player is DirectShow player and most other too.
VirtualDub not use DirectShow filters - required VfW codecs (or wrapper as ffdshow VfW).
Repeat...
Switch-on VP6F in ffdshow VfW configuration?
ffdshow video encoder configuration > Decoder > Codecs > VP6F (and FLV1)

@fccHandler:
On [Input playback] of the short file maryann.wma downloaded from http://heustess.com/soundbytes.htm I get the following error message:
The audio codec reported an error while decompressing audio data. Error code 512 (ACMERR_NOTPOSSIBLE)
I also get this error message from the longer files downloaded from http://heustess.com/music.htm

But the truth - if played decompressed, but not filtered - right at the end shows the message: " The audio codec reported an error while decompressing audio data. Error code: 512 (ACMERR_NOTPOSSIBLE) "
Preview inpet - bad
Preview filtered - good |
