mpp解码问题
本帖最后由 kato0315 于 2020-9-28 14:29 编辑下载官方镜像ROC-RK3328-PC-UBUNTU18.04-GPT-20200630-1405.img，从github上获取mpp源码。
试跑mpi_dec_test后发现有报错，也没有yuv数据输出到文件上。

lz，你还能从github上下载mpp代码吗？ luo 发表于 2020-9-30 15:47

https://github.com/HermanChen/mpp 注意你的test.h264是需要h264 raw数据，不能是打包的数据。 可以通过ffmpeg转换出h264裸流。 kato0315 发表于 2020-9-30 16:17

测试文件应该没有问题

您好，这个功能在哪里打开 楼主好，请问这个解决了吗
