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.
Since version 1.0.7, it is also able to fix very large FLV files with invalid 24-bit timestamps to make proper use of 32-bit extended timestamps.
FLVmeta is written in portable C, it can therefore be compiled on a variety of platforms, including Linux, Windows, and MacOSX. It is also fast and has a very small memory footprint.
