It is a modified version of https://github.com/mozilla/mp4parse-rust Code of Conduct: ================ Contributors to this project agree to the Freedesktop.org Code of Conduct: https://www.freedesktop.org/wiki/CodeOfConduct/ Prerequistes to build: ====================== - a C++ 11 compiler (tested on gcc 4.7 and up) - libboost 1.33.1 (Boost.String, Boost.Test, Boost.Variant) - libjpeg - libxml > 2.5.0 (for the test suite) - libcurl (option for the test suite bootstrap) - Rust 1.64 If building from the git tree you also need: - automake/autoconf - autoconf-archive - pkg-config for the associated m4 macros Optional Gnome support - gdkpixbuf ## Rust crate Starting with 0.4.0, libopenraw is developed as a Rust native crate with a C API. There the standard layout for a Rust crate applies, and `lib/` contains the crate part to build the dynamic library for the C API. Supported file format: ====================== Here are the supported file formats. For details per-camera, see below: - Canon CR2 - Canon CR3 - Canon CRW (not those coming from CHDK firmware like A610) - Nikon NEF and NRW - Olympus ORF - Pentax PEF - Epson ERF - DNG - GoPro GPR - Sony ARW and SR2 - Minolta MRW - Panasonic RAW and RW2 - Fujifilm RAF How to build: ============= Using automake/autoconf: $ ./autogen.sh $ ./configure --prefix=... $ make $ make install DESTDIR=... Supported formats: ================== T Tested and proven to work. (I have a sample.) Y Yes, it is there. (Untested as I do not have a sample but the format is known to be similar.) Yes, it is for the whole format. N Not supported. B Known to be Broken. (Needs to be fixed. I have a sample but further work is required.) X Not needed. # Sample file needed.

It require you to provide your own RAW files and configure it. testsuite/testsuite.xml is an example of valid XML configuration file that works on my local machine. TODO2: provide a better description of the test file. TODO3: fix ordiag to allow outputting a test case in XML. Running the testsuite --------------------- $ make check This will run it automatically. If you need to bootstrap the testsuite, you can go as follow: WARNING: The bootstrap will download "random" files from the internet. They currently aren't validated. $ make $ cd testsuite $ ./testsuite -b -d directory Here directory is the existing directory where files will be downloded. If you build in a different directory than the source directory, you need to set the `srcdir` environment to the path where the testsuite binary is build.
