                 * NOTE: We can choose decoder's buffer mode here.
                 * There are three mode that decoder can support:
                 *
                 * Mode 1: Pure internal mode
                 * In the mode user will NOT call MPP_DEC_SET_EXT_BUF_GROUP
                 * control to decoder. Only call MPP_DEC_SET_INFO_CHANGE_READY
                 * to let decoder go on. Then decoder will use create buffer
                 * internally and user need to release each frame they get.
                 *
                 * Advantage:
                 * Easy to use and get a demo quickly
                 * Disadvantage:
                 * 1. The buffer from decoder may not be return before
                 * decoder is close. So memroy leak or crash may happen.
                 * 2. The decoder memory usage can not be control. Decoder
                 * is on a free-to-run status and consume all memory it can
                 * get.
                 * 3. Difficult to implement zero-copy display path.
                 *
                 * Mode 2: Half internal mode
                 * This is the mode current test code using. User need to
                 * create MppBufferGroup according to the returned info
                 * change MppFrame. User can use mpp_buffer_group_limit_config
                 * function to limit decoder memory usage.
                 *
                 * Advantage:
                 * 1. Easy to use
                 * 2. User can release MppBufferGroup after decoder is closed.
                 *    So memory can stay longer safely.
                 * 3. Can limit the memory usage by mpp_buffer_group_limit_config
                 * Disadvantage:
                 * 1. The buffer limitation is still not accurate. Memory usage
                 * is 100% fixed.
                 * 2. Also difficult to implement zero-copy display path.
                 *
                 * Mode 3: Pure external mode
                 * In this mode use need to create empty MppBufferGroup and
                 * import memory from external allocator by file handle.
                 * On Android surfaceflinger will create buffer. Then
                 * mediaserver get the file handle from surfaceflinger and
                 * commit to decoder's MppBufferGroup.
                 *
                 * Advantage:
                 * 1. Most efficient way for zero-copy display
                 * Disadvantage:
                 * 1. Difficult to learn and use.
                 * 2. Player work flow may limit this usage.
                 * 3. May need a external parser to get the correct buffer
                 * size for the external allocator.
                 *
                 * The required buffer size caculation:
                 * hor_stride * ver_stride * 3 / 2 for pixel data
                 * hor_stride * ver_stride / 2 for extra info
                 * Total hor_stride * ver_stride * 2 will be enough.
                 *
                 * For H.264/H.265 20+ buffers will be enough.
                 * For other codec 10 buffers will be enough.
