I am assuming I need to copy the AVFrame to a smaller AVFrame so I can pass it in. How does one copy a portion of a AVFrame. Do I use av_samples_copy? how do I use that and allocate a AVFrame from it?</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.804800033569336px; background: rgb(255, 255, 255);"><br></p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.804800033569336px; background: rgb(255, 255, 255);">Any help would be greatly appreciated.</p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.804800033569336px; background: rgb(255, 255, 255);"><br></p><p style="margin-bottom: 1em; border: 0px; font-size: 14px; vertical-align: baseline; clear: both; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; line-height: 17.804800033569336px; background: rgb(255, 255, 255);">I have tried:</p><pre class="lang-cpp prettyprint prettyprinted" style="margin-top: 0px; margin-bottom: 10px; padding: 5px; border: 0px; font-size: 14px; vertical-align: baseline; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; overflow: auto; width: auto; max-height: 600px; word-wrap: normal; line-height: 17.804800033569336px; background: rgb(238, 238, 238);"><code style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif; white-space: inherit; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"><span class="typ" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; color: rgb(43, 145, 175); background: transparent;">uint8_t</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;"> </span><span class="pun" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">*</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;"> data </span><span class="pun" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">=</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;"> </span><span class="pun" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">(</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;"> decodeAudio</span><span class="pun" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">.</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">data </span><span class="pun" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">);</span><span class="pln" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; background: transparent;">
