what is libmpcdec</a></h2>
libmpcdec is a library that decodes musepack compressed audio data. Musepack is a free, high performance, high quality lossy audio compression codec. For more information on musepack visit <a href="http://www.musepack.net.">http://www.musepack.net.</a><h2><a class="anchor" name="using">
using libmpcdec</a></h2>
Using libmpcdec is very straightforward. There are typically four things you must do to use libmpcdec in your application.<h3><a class="anchor" name="step1">
step 1: implement an mpc_reader to provide raw data to the decoder library</a></h3>
The role of the mpc_reader is to provide raw mpc stream data to the mpc decoding library. This data can come from a file, a network socket, or any other source you wish.<p>
See the documentation of <a class="el" href="structmpc__reader__t.html">mpc_reader </a> for more information.<h3><a class="anchor" name="step2">
step2: read the streaminfo properties structure from the stream</a></h3>
This is a simple matter of calling the streaminfo_init() and streaminfo_read() functions, supplying your mpc_reader as a source of raw data. This reads the stream properties header from the mpc stream. This information will be used to prime the decoder for decoding in the next step.<h3><a class="anchor" name="step3">
step 3: initialize an mpc_decoder with your mpc_reader source</a></h3>
This is just a matter of calling the <a class="el" href="mpcdec_8h.html#a13">mpc_decoder_setup()</a> and <a class="el" href="mpcdec_8h.html#a14">mpc_decoder_initialize()</a> functions with your mpc_decoder, mpc_reader data source and streaminfo information.<h3><a class="anchor" name="step4">
step 4: iteratively read raw sample data from the mpc decoder</a></h3>
Once you've initialized the decoding library you just iteratively call the mpc_decoder_decode routine until it indicates that the entire stream has been read.<p>
For a simple example of all of these steps see the sample application distributed with libmpcdec in src/sample.cpp. <hr size="1"><address style="align: right;"><small>Generated on Sun Oct 23 16:35:24 2005 for libmpcdec by
