[gst-devel] Gstreamer transcoding Flash FLV in 0.10

[Matthias Bläsing]

Hey,

I have a script, that should do what you want - It's pretty rougth, but
could be improved:

http://www.doppel-helix.eu/any_to_flv

This is python utilizing the gstreamer bindings and uses yamdi to insert
metadata. This can be trivially changed to flvtool2.

HTH
