Description: RichFLV is a free Adobe Air tool that performs a number of operations on FLV video files, including merging files, extracting sections from larger FLVs, exporting audio as FLV or MP3, converting to SWF, extracting individual frames to image files, and defining cue-points and metadata. Operations can be performed on the whole video or user-defined sub-sections.
If you’ve been looking for a tool that can work with FLV video (merge, cut, demux, edit) this may be the one you were waiting for. What is interesting about this tool, aside from being FLV-specific is that it can handle (read/write) FLV without the need to install any external codec packs on your system.
