上层 demo 软件很多额外开销

加了 -o 选项有写文件，去掉

去掉写文件性能好太多了，有点没道理，里面 mpp_buffer_get_ptr获取内存地址再拷贝到文件中

进一步分析了下，从mpp_buffer_get_ptr拷贝数据出来的性能很差
这是log，dump_mpp_frame_to_file耗时超过一帧时间，在58~68这个性能级别

硬解码时间，大家都差不多。
现在是解码后的数据搬运时间差距比较大，3288是DDR3，3566是DDR4，CPU性能差再多不应该拷贝720P的数据耗时差了快10倍
3288/3566的CPU算力跑分，有对比过，3288确实会好，3566也不会差很多
