Thanks for your attention,slomo.  I reopen it first for your attention.  I am
not so familiar with the buffer handling.  Maybe the following codes related? 
Please take a moment help me to find it out.My project is blocked by it. Thanks
if (gst_structure_has_field(structure, "codec_data")) {
    extra_data_buf = (GValue *) gst_structure_get_value(structure,

            AML_DUMP_BUFFER(info->configdata, "Audio Codec Data");
