VP6 to H264

[HoodwILL]

What's up guys? Quick question:

I've had a few flash files layin' around for a while, and now I want to watch them on my X360. I typically use meGUI for all my 264/mp4 converting needs, but Media Info is telling me these flv's are encoded with VP6. I was never into flash all that much, and haven't done much encoding with it... can anyone point me in the right direction?

Thanks in advance! :)

Use DirectShowSource() in an Avisynth script and make sure to enable VP6F decoding in ffdshow. You can use the same for audio with audio=true, and you can check the delay (if any) by demuxing timecodes with moitah's flvextract.

Hmm. Well I currently don't have ffdshow installed, I am running Vista64 and I didn't think there was a stable version available. Also, what kinds of things will ffdshow install? Additional codecs? Will it try and be the default decoder? Because I'm not really in a rush to try it if that's the case.

Use 32-bit ffdshow if you're using MeGUI. You can set it not to be default quite easily: the point is that you need a VP6/VP6F decoder installed to use DirectShowSource() on them. If you can already watch them in a 32-bit media player, then you already have the necessary decoder.

or use mencoder (cli app) that doesn't install anything with something like;

mencoder.exe -ovc raw -oac pcm file.flv -o filen_menc.avi" 2> nul

to get unc avis, or you could make direct conversion to mp4/AVC/AAC if you feel masochistic enough to invent such command line.

sx264 should work,...

Got it. After the ffdshow install, I used flvextract to export the vid to avi, made a new avs and dropped it into meGUI. Worked like a charm!
- Thanks again for the help! :)

there is also a flv DS source filter from the MPC project.
once installed you can use DirectShowSource() to open your flv file directly from avisynth.

Does the ffmepg VP6 decoder offer controllable preprocessing? If so, tweaking that could be a big help in getting optimum detail without propogating forward too many blocking artifacts.

VP6's preprocessing was definitely its most impressive feature. It's amazing what it gets away with when you compare the same files with it off.
