AVInfo is a utility for displaying AVI, MPEG (1 and 2), OGM, MKV, and IFO (DVD) information. It returns the length of a clip, FPS, resolution, codec, audio and video bit rate, number of key frames, sound parameters, the number and type of streams, and the language for audio/subtitles. It then generates a file list with statistics (HTML, plain text, or CSV).
dwarf-ng is a small and powerful object file manipulator. With dwarf-ng, you can read, edit, and manipulate section headers, inject code or data, and create new section headers of object files. Currently, it handles object files in the PE, Mach-O, and ELF formats. For the moment, dwarf-ng only has a command-line interface. dwarf-ng is fully scriptable (as it has a scripting language), and is flexibly configurable.
