flvmeta is a metadata injector for FLV video files. FLVmeta aims to be a replacement for tools such as flvtool2. It is able to inject all known metadata tags into the onMetaData event, as well as insert an onLastSecond event. flvmeta is also able to fix very large FLV files with invalid 24-bit timestamps to make proper use of 32-bit extended timestamps. It is written in portable C, and can therefore be compiled on a variety of platforms, including Linux, Windows, and MacOSX. It is also pretty fast and has a very small memory footprint.
