RK3399Pro入门教程（6）硬件编解码器MPP库的使用

是的，GitHub 上有我们对接好的ffmpeg和gsteamer

大神，github 的地址发一下，可以吗？

编译完源码后，test中的执行文件运行后都没有任何输出和报错，请问这是什么原因

有个版本mpp他输出输到syslog里去了，你用journalctl来看看

好的，谢谢

沙发,大佬，请问你有使用mpp实现硬解码吗？

您好，我这边是rk1808的板子，系统是debian9，在运行官方测试程序mpi_dec_test的时候，输出如下：

1. root@rk1808:~/rtsp# ./mpi_dec_test -t 7 -i Tennis1080p.h264 -n 9
   
2. mpi_dec_test: cmd parse result:

33. mpi_dec_test: decoder_get_frame get err info:1 discard:0.
    
34. mpi_dec_test: decode_get_frame get frame 8
    
35. mpi_dec_test: decoder_get_frame get err info:1 discard:0.
    
36. mpi_dec_test: decode_get_frame get frame 9
    
37. mpi_dec_test: reach max frame number 9
    
38. mpi_dec_test: test success max memory 14.34 MB
    

复制代码

虽然最后提示成功，但是感觉有问题，每次get err info都是1。

另外，如果我把-n选项调大一点，比如执行命令：

1. ./mpi_dec_test -t 7 -i Tennis1080p.h264 -n 1000

复制代码

期间就会有这样的输出：

1. mpp_device: mpp_device_send_reg ioctl VPU_IOC_SET_REG failed ret -1 errno 14 Bad address
   
2. hal_h264d_vdpu_reg: H264 VDPU FlushRegs fail, pid=641.
   
3. mpi_dec_test: decoder_get_frame get err info:1 discard:0.
   
4. mpi_dec_test: decode_get_frame get frame 119
   
5. mpi_dec_test: decoder_get_frame get err info:1 discard:0.
   
6. mpi_dec_test: decode_get_frame get frame 120
   
7. mpp_device: mpp_device_wait_reg ioctl VPU_IOC_GET_REG failed ret -1 errno 110 Connection timed out
   
8. hal_h264d_vdpu_reg: H264 VDPU wait result fail, pid=641.
   
9. mpi_dec_test: decoder_get_frame get err info:1 discard:0.
   

复制代码

内核是4.4.194的，/dev/vpu_service设备文件也是存在的。

请问一下，这会是什么问题？

求道友来一份depian10的H264编码源码 万分感谢

道友有编码源码了吗，来一份，十万分感谢

下载源码 编译安装之后
“-- Installing: /usr/local/include/rockchip
-- Installing: /usr/local/includ ...

深得我心，看见大家都这么难我就放心了

是否只有toybrick的才能安装？   我的为什么安装的时候都是显示unable to locate package rockchip-***

已解决
楼主好，我在使用mpp解码时遇到了如下问题：就是判断不了mpp正常运行了没有，还是代码哪里出错了。我debug了一下，发现frame是空的但是返回的ret是成功。
1.在执行mpi_dec_test时，日志会有这样的信息Sep 03 03:43:50 debian10.toybrick kernel: rk_vcodec: vpu_service_ioctl:2140: error: unknown vpu service ioctl cmd 40086c01与手册上的不同，但是最后会显示test success。这对程序的正常执行会不会有影响。
2.我对mpi_dec_test基础上加将读取的帧转换成jpg保存起来（copy的github上的FFMPEG代码），发现保存的图片是空的。3.在ffmpeg_rtsp_mpp-master执行后读取的yuv文件也是花屏（yuvplayer）
