<div class="textblock"><p>Data-passing buffer type. </p>
<p>See also: <a class="el" href="classGst_1_1Pad.html" title="A class that represents objects contained by elements that allows links to other elements. ">Pad</a>, <a class="el" href="classGst_1_1MiniObject.html" title="This is a base class for some gstreamermm objects. ">MiniObject</a>, <a class="el" href="classGst_1_1Memory.html" title="GstMemory is a lightweight refcounted object that wraps a region of memory. ">Memory</a>, Meta, BufferPool</p>
<p>Buffers are the basic unit of data transfer in GStreamer. They contain the timing and offset along with other arbitrary metadata that is associated with the #GstMemory blocks that the buffer contains.</p>
<p>Buffers are usually created with <a class="el" href="classGst_1_1Buffer.html#a5b2694b0e0dfef39207ab92c72db5b53">Gst::Buffer::create</a>. After a buffer has been created one will typically allocate memory for it and add it to the buffer. The following example creates a buffer that can hold a given video frame with a given width, height and bits per plane.</p>
<p>Buffers can contain a list of <a class="el" href="classGst_1_1Memory.html" title="GstMemory is a lightweight refcounted object that wraps a region of memory. ">Gst::Memory</a> objects. You can retrieve how many memory objects with <a class="el" href="classGst_1_1Buffer.html#aa6d6c4d67bc3fae4f75fc3f57bffe031" title="Get the amount of memory blocks that this buffer has. ">n_memory()</a> and you can get a pointer to memory with <a class="el" href="classGst_1_1Buffer.html#ab99330eead323d11ab0bfe25159c5516" title="Get the memory block at idx in buffer. ">peek_memory()</a></p>
<p>A buffer will usually have timestamps, and a duration, but neither of these are guaranteed (they may be set to #GST_CLOCK_TIME_NONE). Whenever a meaningful value can be given for these, they should be set. The timestamps and duration are measured in nanoseconds (they are <a class="el" href="namespaceGst.html#ad35f82b74cae5822fe16b231e8293cda" title="A data type to hold a time, measured in nanoseconds. ">Gst::ClockTime</a> values).</p>
<p>The buffer DTS refers to the timestamp when the buffer should be decoded and is usually monotonically increasing. The buffer PTS refers to the timestamp when the buffer content should be presented to the user and is not always monotonically increasing.</p>
<p>A buffer can also have one or both of a start and an end offset. These are media-type specific. For video buffers, the start offset will generally be the frame number. For audio buffers, it will be the number of samples produced so far. For compressed data, it could be the byte offset in a source or destination file. Likewise, the end offset will be the offset of the end of the buffer. These can only be meaningfully interpreted if you know the media type of the buffer (the preceeding CAPS event). Either or both can be set to Gst::BUFFER_OFFSET_NONE.</p>
<p>To efficiently create a smaller buffer out of an existing one, you can use <a class="el" href="classGst_1_1Buffer.html#a6423c4c589568bf262197322ca4e5481" title="Creates a sub-buffer from parent at offset and size. ">copy_region()</a>. This method tries to share the memory objects between the two buffers.</p>
<p>If a plug-in wants to modify the buffer data or metadata in-place, it should first obtain a buffer that is safe to modify by using <a class="el" href="classGst_1_1Buffer.html#a48d6843caf65c5004c7258a9cd1fe315" title="Makes a writable buffer from the given buffer. ">create_writable()</a>. This function is optimized so that a copy will only be made when it is necessary.</p>
<p>Several flags of the buffer can be set and unset with the GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use GST_BUFFER_FLAG_IS_SET() to test if a certain Gst::BufferFlag is set.</p>
<p>Buffers can be efficiently merged into a larger buffer with <a class="el" href="classGst_1_1Buffer.html#a6eaed6c589650e08e5fe8dafc255eae9">append()</a>. Copying of memory will only be done when absolutely needed.</p>
<p>Arbitrary extra metadata can be set on a buffer with add_meta(). Metadata can be retrieved with get_meta(). See also Gst::Meta</p>
<p>An element should either unref the buffer or push it out on a src pad using <a class="el" href="classGst_1_1Pad.html#ab8f95c947da472b6cd7284ffca9b5b30" title="Pushes a buffer to the peer of pad.
