@mainpage libdcp
libdcp is a small library to create Digital Cinema Packages (DCPs) from JPEG2000 and WAV files.
Most of the hard work is done by a (slightly patched) version of asdcplib (http://www.cinecert.com/asdcplib/)
which is included in the source distribution for libdcp.
libdcp is distributed under the GNU GPL.
Typical use might be:
@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%).
If you can generate content paths algorithmically, you may prefer to do something
like this:
@code
string
j2k_path (int frame)
{
stringstream s;
s << "my_j2ks/" << frame << ".j2c"
return s.str ();
}
string
wav_path (libdcp::Channel channel)
{
switch (channel) {
case LEFT:
return "left.wav";
case RIGHT:
return "right.wav";
}
return "";
}
...
// Our images are 1998x1080 (DCI Flat)
dcp.add_picture_asset (sigc::ptr_fun (&j2k_path), 1998, 1080);
// We have two sound channels
dcp.add_sound_asset (sigc::ptr_fun (&wav_path), 2);
...
@endcode
