A cli-tool for inspecting content & metadata of files compliant to the RIFF container format.
Disclaimer: This software is part of a larger project I've been working on in my free time. I threw it together on short notice and I intend to patch additional functionality as time goes on. My experience with the C programming language is very limited and this software is mostly intended to be a fun and rewarding programming exercise. If you intend to use this software, please do so with caution. It's probably likely terribly written and you should keep that in mind.
Usage: riffdump [OPTION...]
-c, --count Count subchunks
-l, --list List subchunks
-s, --sub=<chunk> Specify the chunk to operate on (Default: RIFF)
-v, --verbose Produce verbose output
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
The following examples illustrate the most common use cases and serve as a short introduction to the software.
riffdump [file] - Retreives the extension identifier of a given RIFF-based file. This should describe the actual content type of the leading RIFF chunk that is the root of all subchunks. Fails if the file is not recognized as a valid implementation of RIFF.
riffdump [file] -c - Counts the number of subchunks that are direct descendants of the leading RIFF chunk. Does not count subchunks of subchunks (i.e. if a LIST subchunk is present).
riffdump [file] -c -s "LIST" - Counts the number of subchunks that are direct descendants of the specified LIST subchunk. Does not count subchunks of subchunks (i.e. if another LIST subchunk is part of the specified LIST subchunk).
riffdump [file] -l - Lists all subchunks that are direct descendants of the leading RIFF chunk. Does not list subchunks of subchunks (i.e. if a LIST subchunk is present). Subchunks are identified by their respective FourCC identifier.
riffdump [file] -l -s "LIST" - Lists all subchunks that are direct descendants of the specified LIST subchunk. Does not list subchunks of subchunks (i.e. if another LIST subchunk is part of the specified LIST subchunk). Subchunks are identified by their respective FourCC identifier.
riffdump [file1] [file2] [...] - Retreives the extension identifier of all given RIFF-based files. Processing multiple files at once is supported but not always recommended as this potentially removes explicit interpretations for the output. Readability is key, never sacrifice it.
riffdump -v ... - Produces verbose output. This works with most options and improves readability for humans. In general, verbose output is formatted and might include additional metadata.
