                     *
                     * 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.
