Demux/Remux h264 f4v?

[filetree]

I am using Adobe Live Media Encoder to stream, and it says out h264 as an f4v, and NOTHING can edit this.
I'd love to be able to remux to at the minimum FLV.
Would be great to demux the h264 and mp3 streams and remux to mp4.

I've searched, and found nothing

ffmpeg -i in.f4v -vcodec copy -acodec copy -y out.mp4

If you want a GUI, Super Video converter can extract streams from one container and mux them into another, but it can be hit and miss at times. FormatFactory also has a function for doing the same thing under "Advanced". Actually, I'd try FormatFactory first.

Both programs support a lot of different input file types, but I'm not sure f4v is one of them. There's a very good chance simply exchanging the extension to flv will have any program which opens flv files then able to open them. It usually works for the MP4 variants such as m4v if they don't include DRM.

AviDemux can open h.264/mp3 FLV files and save out to mp4 or mkv. It is a direct stream copy so there is no recompression.

I find the daily builds of version 2.6 keeps flv video/audio in sync. I have problems with sync with the 2.5 branch.
