Note that this only allocates the <a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> itself, the buffers for the data must be managed through other means (see below). <a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> must be freed with <a class="el" href="group__lavu__frame.html#ga979d73f3228814aee56aeca0636e37cc" title="Free the frame and any dynamically allocated objects in it, e.g.">av_frame_free()</a>.</p>
<p><a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> is typically allocated once and then reused multiple times to hold different data (e.g. a single <a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> to hold frames received from a decoder). In such a case, <a class="el" href="group__lavu__frame.html#ga0a2b687f9c1c5ed0089b01fd61227108" title="Unreference all the buffers referenced by frame and reset the frame fields.">av_frame_unref()</a> will free any references held by the frame and reset it to its original clean state before it is reused again.</p>
<p>The data described by an <a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> is usually reference counted through the AVBuffer API. The underlying buffer references are stored in <a class="el" href="structAVFrame.html#a4a64d05cc676bfa8e18bf22d16c8a51f" title="AVBuffer references backing the data for this frame.">AVFrame.buf</a> / <a class="el" href="structAVFrame.html#a254a144d113ceedc003ec1547cc5bd54" title="For planar audio which requires more than AV_NUM_DATA_POINTERS AVBufferRef pointers, this array will hold all the references which cannot fit into AVFrame.buf.">AVFrame.extended_buf</a>. An <a class="el" href="structAVFrame.html" title="This structure describes decoded (raw) audio or video data.">AVFrame</a> is considered to be reference counted if at least one reference is set, i.e. if <a class="el" href="structAVFrame.html#a4a64d05cc676bfa8e18bf22d16c8a51f" title="AVBuffer references backing the data for this frame.">AVFrame.buf</a>[0] != NULL. In such a case, every single data plane must be contained in one of the buffers in <a class="el" href="structAVFrame.html#a4a64d05cc676bfa8e18bf22d16c8a51f" title="AVBuffer references backing the data for this frame.">AVFrame.buf</a> or <a class="el" href="structAVFrame.html#a254a144d113ceedc003ec1547cc5bd54" title="For planar audio which requires more than AV_NUM_DATA_POINTERS AVBufferRef pointers, this array will hold all the references which cannot fit into AVFrame.buf.">AVFrame.extended_buf</a>. There may be a single buffer for all the data, or one separate buffer for each plane, or anything in between.</p>
<p>sizeof(AVFrame) is not a part of the public ABI, so new fields may be added to the end with a minor bump. Similarly fields that are marked as to be only accessed by <a class="el" href="group__avoptions.html#gab1d208d09e487741a28016919225bef6" title="Gets a pointer to the requested field in a struct.">av_opt_ptr()</a> can be reordered. This allows 2 forks to add fields without breaking compatibility with each other. </p>
