Video output mode is bitrate based, format flash video, container, flash video - source is auto select - Backend is VFW with the codec file path set C:\WINDOWS\system32\vp7vfw.dll.

Now I hit start it goes through a testing phase which seems to take forever as in the time tab I only way the first 30 sec. So I usually hit skip - then it switches to transcoding in progress, but I never get a VP7 config window :(..... ????
Vorbis audio and VP7 video is not supported by FLV.

FLV support only:
- H.364/FLV1 or VP6 video with audio MP3 or Nellymoser or ADPCM,
- H.264/AVC video with AAC audio.

Why encode to FLV?


BTW
Adobe Flash Player (9 and 10) support MP4 and MOV (with H.264/AVC video and AAC audio) too - not only FLV.
FLV with H.264 and AAC is currently used on YouTube and some other.
If You want...
In MediaCoder must:
- encode to MP4 (H.264/AAC)
- open new .mp4 file and re-mux to FLV (copy audio/video to FLV container)
... of course for this use latest 'stable' or development MediaCoder build.

Yes I'm aware of that, and I'm doing some testing on VP7 so It needs to be PV7 - I can do without the Vorbis audio, but I do need at least the flv on2vp7 video and an audio format that is supported

Can't.


If You look at Warp Video Player or Jittr Video Player... it not use FLV, but encypted AVI with VP7 video video and separately OGG Vorbis audio.

So there is no way to get a flv with on2vp7?

Can I get mp4 with on2vp7?

So what is possible with on2vp7? If the files on on2's website are not FLV and not MP4 what are they?

It's AVI container (with .vp7 extension) - maybe slightly modified, but still AVI.
File with .tc8 exension is similar to .asx, .wvx, .ram, ... - it's just text file with redirection to video stream and few other infos.

AHH OK gotcha now... I still want to get my h264 file encoded with the vp7 codec - now I take it that I can use the Vorbis audio if I'm using AVI as the container? and on2 as the codec?

Vorbis in AVI? It's very problematic...
Can use FFmpeg as encoder, but transcoded file probably will not be playable correctly.

Of course can just use VirtualDub and Vorbis ACM codec, but...

What is the purpose? :?

I dont think virtual dub will open my QT mov h264 file?

actually my source file is MPEG-4 with AVC codec (FourCC: avc1)
