Lots of Trouble Converting FLV to AVI

[elykl335]

Hey everyone,

I'm a complete newcomer when it comes to all of this video stuff. I have recently started doing Starcraft 2 commentaries, and hence have been using Fraps to capture the video, and then stitching it together using VirtualDub and the XviD MPEG 4 codec.

Today, I got started with streaming. The local recording is one 40 minute long FLV file. I want to split it up into separate segments, and I have read all over these forums (I've been looking all day) on different ways to open it in VirtualDub, or convert it to AVI. I can not open it in VirtualDub, I have tried using FLV Extract, and have tried using WinFF and VLC to convert, or to do anything with it that might make it usable. All of these failed, I'm assuming because I do not have ffdshow setup/configured correctly.

Can someone please help me out with configuring it properly? Whether it be opening it in VirtualDub (preferred), converting it, or anything else, I just want an easy way to be able to split up this file. Preferably without installing another program for video editing specifically for the FLVs.

I am running Windows 7 64 bit.

Maybe, download this http://fcchandler.home.comcast.net/~fcchandler/Plugins/FLV/index.html and follow the instructions in the readme.
Cheers.

Definitely got me closer. Now it loads and says Missing Codec [AVC1]. I do have the H.264/AVC Codec enabled in the ffdshow VFW configuration. Upon playing, it says "No audio decompressor could be found to decompress the source audio format."

Hmmm. ffdshow should work; you might want to check FLV1 on the ffdshow decoder tab.
Are you using the 64 bit version of ffdshow AND the 64 bit version of Virtualdub?
If not, download and install the matching version(s).

p.s. Installing both the 64 bit AND the 32 bit versions of ffdshow can save a lot of hassles.

I have ensured that I have 64 bit VirtualDub as well as ffdshow. I have read that I have to have the FLV1 and VP6F codecs set to libavcodec. Is this in both the VFW Configuration and Video Decoder Configuration? Do I have to have anything set in the Audio Decoder Configuration, besides MP3?

Also, I have heard that many people use FLVextract to deal with FLV files. However, when I try this, the resulting video comes out as a ".264" format, and neither VLC nor VirtualDub can open it. Does anyone know what might fix this?

I see above you have enabled h.264/avc in the configuratoin as well, make sure it's the VFW config

try installing x264vfw

if the audio is aac, then you might need aacacm as well

alternatively, you can use the vdub directshow input driver plugin to open flv files

or load through an avs script (this is the most reliable method by far)

This is elementary video, vdub isn't supposed to be able to open it

You need to put it into a container. eg. mkvtoolnix for mkv, then use the vdub mkv plugin


If none of these work, try using ffdshow 32bit, vdub 32bit, or use a different converter like avidemux, xvid4psp, any video converter, mediacoder etc...
