# File Formats

[Odin](https://github.com/odin-lang/Odin) implementations of various file formats (WIP).

## ISO Base Media File Format (BMFF)

The base container format used for `MP4`, `HEIF`, `JPEG 2000`, and other formats.

Implemented from [ISO/IEC Standard 14496, Part 12](https://www.iso.org/standard/68960.html), fifth edition 2015-12-15 specification.

See also: [Library of Congress archivist's information about the format](https://www.loc.gov/preservation/digital/formats/fdd/fdd000079.shtml).

### Status

* `open`  opens a file and returns a handle.

* `close` closes the file and cleans up anything allocated on behalf of the user.

* `parse` parses the opened file.

* `print` prints the parse tree.

* Various convenience functions to convert things to Odin-native types.

* Initial test harness.

### TODO

* Add parse options, e.g. parse / don't parse the `mdat` box, etc.

* Add handlers for more box types.

* Add more box constraints, e.g. type `foo_` may appear only in `bar_`, zero or more times.

* Add a writer.

## Extensible Binary Meta Language (EBML)

The base container format used for `Matroska` and `WebM`.

Implemented from [RFC 8794](https://datatracker.ietf.org/doc/rfc8794/) and the [Matroska](https://www.ietf.org/archive/id/draft-ietf-cellar-matroska-08.html) specification.

### Status

* `open`  opens a file and returns a handle.

* `close` closes the file and cleans up anything allocated on behalf of the user.

* `parse` parses the opened file.

* `print` prints the parse tree.

* Various convenience functions to convert things to Odin-native types.

* Initial test harness.

### TODO

* Add parse options, e.g. parse / skip clusters, etc.

* Add more element constraints, e.g. type `foo_` may appear only in `bar_`, zero or more times.

* Add a writer.

* Add tables and enums for [tags](https://datatracker.ietf.org/doc/html/draft-ietf-cellar-tags-06) and [codecs](https://datatracker.ietf.org/doc/html/draft-ietf-cellar-codec-06).

## Other file formats

TBD. Various compression algoritms and file formats are under construction in my compression repository.
