+### test_decoder
+
+`test_decoder` 展示了如何使用不同平台的解码器,解码不同的编码类型.
+
+`test_decoder` 支持一些配置项, 如下:
+
+- codec_name : 解码器名称 (可以通过 `-h` 查看具体支持的解码器)
+- input : 输入文件
+- display : 是否输出至屏幕
+- fps : 刷新帧率
+
 ## 其他
 
 在不同的平台上, 或者不同的驱动上, 相同的测试用例可能出现不同的效果, 或者更严重点甚至无法运行或者崩溃.

+### test_decoder
+
+`test_decoder` demonstrates how to use decoders on different platforms to decode various types of codecs.
+
+`test_decoder` supports several configuration options as follows:
+
+- codec_name: Name of the decoder (you can view the supported decoders using `-h`)
+- input: Input file
+- display: Whether to output to the screen
+- fps: Refresh rate
+
 ## Others
 
 On different platforms or drivers, identical test cases may yield different results or even fail or crash due to cross-platform compatibility issues that are hard to detect and address during development or due to logical errors within MMP-Core itself.
