+`MaixPy` supports playing `h264`, `mp4` and `flv` video formats, note that currently only `avc` encoded `mp4` and `flv` files are supported. Additionally, due to hardware encoder limitations, if you encounter issues decoding the video during playback, try re-encoding it with `ffmpeg` and then play it again. Refer to the following command:
+
+```shell
+ffmpeg -i input_video.mp4 -c:v libx264 -x264opts "bframes=0" -c:a aac -strict experimental output_video.mp4

+`MaixPy`支持播放`h264`、`mp4`、`flv`格式的视频，需要注意目前只支持`avc`编码的`mp4`和`flv`文件。此外由于硬件编码器限制，如果播放视频时发现无法解码，先尝试`ffmpeg`重新编码一遍后再试，参考命令：
