Are there any programs for Ubuntu 13.04 that allow the user to edit the metadata of FLV videos? I would prefer a graphical user interface. Command-lines are fine if that is all that exists.
flvmeta is a command line tool available for Windows, Mac and Linux that can add metadata (in the form of a string) to flv files
(replace NAME and VALUE with your values)
You can check whether the metadata has been added by running
Please note that flvmeta 1.1.0 at least is needed for this to work, while the version packaged for Ubuntu 13.04 is an old release, v1.0.11.
PiTiVi - allows users to easily edit audio/video projects based on the GStreamer framework. PiTIVi provides several ways of creating and modifying a timeline. Ranging from a simple synopsis view (a-la iMovie) to the full-blown editing view (aka Complex View) which puts you in complete control of your editing.
For install it from a terminal, use next command:
