|
|
<p>The level 2 interface provides read-write access to FLAC file metadata; all metadata is read into memory, operated on in memory, and then written to file, which is more efficient than level 1 when editing multiple blocks. </p>
|
|
<p>Currently Ogg FLAC is supported for read only, via <a class="el" href="group__flac__metadata__level2.html#ga3995010aab28a483ad9905669e5c4954">FLAC__metadata_chain_read_ogg()</a> but a subsequent <a class="el" href="group__flac__metadata__level2.html#ga46bf9cf7d426078101b9297ba80bb835">FLAC__metadata_chain_write()</a> will fail.</p>
|
|
<p>The general usage of this interface is:</p>
|
|
<ul>
|
|
<li>Create a new chain using <a class="el" href="group__flac__metadata__level2.html#ga381a1b6efff8d4e9d793f1dda515bd73">FLAC__metadata_chain_new()</a>. A chain is a linked list of FLAC metadata blocks.</li>
|
|
<li>Read all metadata into the the chain from a FLAC file using <a class="el" href="group__flac__metadata__level2.html#ga5a4f2056c30f78af5a79f6b64d5bfdcd">FLAC__metadata_chain_read()</a> or <a class="el" href="group__flac__metadata__level2.html#ga3995010aab28a483ad9905669e5c4954">FLAC__metadata_chain_read_ogg()</a> and check the status.</li>
|
|
<li>Optionally, consolidate the padding using <a class="el" href="group__flac__metadata__level2.html#ga0a43897914edb751cb87f7e281aff3dc">FLAC__metadata_chain_merge_padding()</a> or <a class="el" href="group__flac__metadata__level2.html#ga82b66fe71c727adb9cf80a1da9834ce5">FLAC__metadata_chain_sort_padding()</a>.</li>
|
|
<li>Create a new iterator using <a class="el" href="group__flac__metadata__level2.html#ga1941ca04671813fc039ea7fd35ae6461">FLAC__metadata_iterator_new()</a></li>
|
|
<li>Initialize the iterator to point to the first element in the chain using <a class="el" href="group__flac__metadata__level2.html#ga2e93196b17a1c73e949e661e33d7311a">FLAC__metadata_iterator_init()</a></li>
|
|
<li>Traverse the chain using FLAC__metadata_iterator_next and <a class="el" href="group__flac__metadata__level2.html#gaa28df1c5aa56726f573f90e4bae2fe50">FLAC__metadata_iterator_prev()</a>.</li>
|
|
<li>Get a block for reading or modification using <a class="el" href="group__flac__metadata__level2.html#gad3e7fbc3b3d9c192a3ac425c7b263641">FLAC__metadata_iterator_get_block()</a>. The pointer to the object inside the chain is returned, so the block is yours to modify. Changes will be reflected in the FLAC file when you write the chain. You can also add and delete blocks (see functions below).</li>
|
|
<li>When done, write out the chain using <a class="el" href="group__flac__metadata__level2.html#ga46bf9cf7d426078101b9297ba80bb835">FLAC__metadata_chain_write()</a>. Make sure to read the whole comment to the function below.</li>
|
|
<li>Delete the chain using <a class="el" href="group__flac__metadata__level2.html#ga46b6c67f30db2955798dfb5556f63aa3">FLAC__metadata_chain_delete()</a>.</li>
|
|
</ul>
|
|
<dl class="section note"><dt>Note</dt><dd>Even though the FLAC file is not open while the chain is being manipulated, you must not alter the file externally during this time. The chain assumes the FLAC file will not change between the time of <a class="el" href="group__flac__metadata__level2.html#ga5a4f2056c30f78af5a79f6b64d5bfdcd">FLAC__metadata_chain_read()</a>/FLAC__metadata_chain_read_ogg() and <a class="el" href="group__flac__metadata__level2.html#ga46bf9cf7d426078101b9297ba80bb835">FLAC__metadata_chain_write()</a>.</dd>
|
|
<dd>
|
|
Do not modify the is_last, length, or type fields of returned <a class="el" href="structFLAC____StreamMetadata.html">FLAC__StreamMetadata</a> objects. These are managed automatically.</dd>
|
|
<dd>
|
|
The metadata objects returned by <a class="el" href="group__flac__metadata__level2.html#gad3e7fbc3b3d9c192a3ac425c7b263641">FLAC__metadata_iterator_get_block()</a> are owned by the chain; do not <a class="el" href="group__flac__metadata__object.html#ga6b3159744a1e5c4ce9d349fd0ebae800">FLAC__metadata_object_delete()</a> them. In the same way, blocks passed to <a class="el" href="group__flac__metadata__level2.html#gaf61795b21300a2b0c9940c11974aab53">FLAC__metadata_iterator_set_block()</a> become owned by the chain and they will be deleted when the chain is deleted. </dd></dl>

<p>Write all metadata out to the FLAC file. This function tries to be as efficient as possible; how the metadata is actually written is shown by the following:</p>
|
|
<p>If the current chain is the same size as the existing metadata, the new data is written in place.</p>
|
|
<p>If the current chain is longer than the existing metadata, and <em>use_padding</em> is <code>true</code>, and the last block is a PADDING block of sufficient length, the function will truncate the final padding block so that the overall size of the metadata is the same as the existing metadata, and then just rewrite the metadata. Otherwise, if not all of the above conditions are met, the entire FLAC file must be rewritten. If you want to use padding this way it is a good idea to call <a class="el" href="group__flac__metadata__level2.html#ga82b66fe71c727adb9cf80a1da9834ce5">FLAC__metadata_chain_sort_padding()</a> first so that you have the maximum amount of padding to work with, unless you need to preserve ordering of the PADDING blocks for some reason.</p>
|
|
<p>If the current chain is shorter than the existing metadata, and <em>use_padding</em> is <code>true</code>, and the final block is a PADDING block, the padding is extended to make the overall size the same as the existing data. If <em>use_padding</em> is <code>true</code> and the last block is not a PADDING block, a new PADDING block is added to the end of the new data to make it the same size as the existing data (if possible, see the note to <a class="el" href="group__flac__metadata__level1.html#gae1dd863561606658f88c492682de7b80">FLAC__metadata_simple_iterator_set_block()</a> about the four byte limit) and the new data is written in place. If none of the above apply or <em>use_padding</em> is <code>false</code>, the entire FLAC file is rewritten.</p>
|
|
<p>If <em>preserve_file_stats</em> is <code>true</code>, the owner and modification time will be preserved even if the FLAC file is written.</p>
|
|
<p>For this write function to be used, the chain must have been read with <a class="el" href="group__flac__metadata__level2.html#ga5a4f2056c30f78af5a79f6b64d5bfdcd">FLAC__metadata_chain_read()</a>/FLAC__metadata_chain_read_ogg(), not <a class="el" href="group__flac__metadata__level2.html#ga595f55b611ed588d4d55a9b2eb9d2add">FLAC__metadata_chain_read_with_callbacks()</a>/FLAC__metadata_chain_read_ogg_with_callbacks().</p>

<p>The <em>temp_handle</em> must be open for writing. The equivalent minimum stdio fopen() file mode is <code>"w"</code> (or <code>"wb"</code> for Windows). It should be an empty stream, or at least positioned at the start-of-file (in which case it is the caller's duty to truncate it on return).</p>
