How to open FLV files with AviSynth

For FLV videos using VP6 codec:
Create AVS script:

DirectShowSource("C:\clip.flv",fps=29.97,convertfps=true)

You will need FLVSplitter.ax installed into System32 folder, and DGDecode.dll in Avisynth Plug-ins folder.


For FLV videos using FLV1 codec
Type in the console

C:\WINDOWS\system32\rundll32.exe ffdshow.ax,configure

(make sure to change to your ffdshow directory)
Alternetively find the "ffdshow/videodecoder configuration" in your Windows Start Menu.

Click on Codecs and enable FLV1 (set to libavcodec).

Install Gabest flvsplitter. Then

regsvr32 path\to\filter.dll

Create AVS script:

DirectShowSource("C:\clip.flv")

Then you can open the AVS script with Virtual Dub, use AVIsynth PlugIn for Adobe Premiere to open AVS scripts,...

You can also use VirtualDub plug-ins for opening FLV files
