- * @code
- * #include <libdcp/dcp.h>
- * using namespace std;
- *
- * libdcp::DCP dcp ("My Film DCP", "My Film", libdcp::DCP::FEATURE, 24, 50000);
- *
- * vector<string> j2k_files;
- * j2k_files.push_back ("1.j2c");
- * ...
- * j2k_files.push_back ("50000.j2c");
- *
- * // These images are 1998x1080 pixels (DCI Flat)
- * dcp.add_picture_asset (j2k_files, 1998, 1080);
- *
- * vector<string> wav_files;
- * wav_files.push_back ("L.wav");
- * wav_files.push_back ("R.wav");
- * wav_files.push_back ("C.wav");
- * wav_files.push_back ("Lfe.wav");
- * wav_files.push_back ("Ls.wav");
- * wav_files.push_back ("Rs.wav");
- * dcp.add_sound_asset (wav_files);
- *
- * dcp.write_xml ();
- *
- * @endcode
- *
- * This will create a DCP at 24 frames per second with 50000 frames, writing
- * data to a directory "My Film DCP", naming the DCP "My Film" and marking
- * as a Feature. We then add the picture and sound files (which creates
- * MXF files inside the DCP directory) and then write the required XML files.
- *
- * If you want to report progress for long jobs (add_picture_asset() can
- * take a long time, in particular, as it must do a lot of disk I/O for
- * large DCPs), connect to the libdcp::DCP::Progress signal and report its parameter
- * to the user (it will range between 0 for 0% and 1 for 100%).
