news2024/11/16 5:35:18

1. 简介

  • [RK3588从入门到精通] 专栏总目录

  • mpi_dec_test 是rockchip官方解码 demo

  • 本篇文章进行mpi_dec_test 的代码解析,解码流程解析

2. 环境介绍

  • 硬件环境:
    ArmSoM-W3 RK3588开发板

  • 软件版本:
    OS:ArmSoM-W3 Debian11

3. mpp解码流程解析

在这里插入图片描述

  • mpp_create :获取 MppCtx 实例以及 MppApi 结构体
  • mpp_init: 初始化MppCtx 的编解码类型与格式
  • mpi->control:通过相应的命令来配置解码参数
  • decode_put_packet:输入码流:编码数据 MppPacke,例如264、265数据
  • decode_get_frame: 获取解码的数据存放到MppFrame,例如YUV、RGB数据
  • mpi->reset:使解码器恢复为正常初始化后的状态。
  • mpp_destroy:释放申请的内存空间,做销毁善后工作

4. 重要函数解析

mpp_init函数:初始化MppCtx 的编解码类型与格式

mpp_init函数原型:

MPP_RET mpp_init(MppCtx ctx, MppCtxType type, MppCodingType coding)

mpp_init函数调用实例:

ret = mpp_init(ctx, MPP_CTX_DEC, MppCodingType::MPP_VIDEO_CodingAVC);
if (ret)
 {
    mpp_err("mpp_init failed ret %d\n", ret);
    goto MPP_TEST_OUT;
 }

mpp_init函数参数解析:

  • MppCtxType 参数:初始化编码还是解码

    MPP_CTX_DEC : 解码
    MPP_CTX_ENC : 编码
    
  • MppCodingType 参数:编解码的格式

    MPP_VIDEO_CodingAVC :   H.264
    MPP_VIDEO_CodingHEVC:   H.265
    MPP_VIDEO_CodingVP8 :   VP8
    MPP_VIDEO_CodingVP9 :   VP9
    MPP_VIDEO_CodingMJPEG : MJPEG
    

5. mpi_dec_test 流程解析

mpi_dec_test 解码命令举例:

sudo mpi_dec_test -i /oem/200frames_count.h264 -t 7 -n 200 -o /oem/decode.yuv -w 1920 -h 1080

mpi_dec_test 流程解析:

main(  ) ---> dec_decode(  ) ---> thread_decode(  ) ---> dec_simple(  ) ---> mpp_destroy(  )
  • main函数根据传进来的参数(参数char **argv 对应命令中的 -i /oem/200frames_count.h264 -t 7 -n 200 -o /oem/decode.yuv -w 1920 -h 1080)对参数进行解析保存到 MpiDecTestCmd * cmd 结构体中
  • dec_decode(cmd) 函数是封装好的解码函数,传入 MpiDecTestCmd * cmd 结构体即可完成解码
  • dec_decode 函数执行了一些MPP的初始化操作:mpp_create() mpp_init() ,mpp_dec_cfg_init() , mpi->control。初始化之后创建解码线程: thread_decode 进行解码。
  • 解码线程: thread_decode 线程根据 cmd->simple 变量判断是使用 dec_simple 解码还是 dec_advanced 解码
  • 解码完最后一帧之后执行 pthread_join() 函数等待解码线程: thread_decode 结束后做线程释放工作
  • 线程释放完毕之后执行reset复位操作:mpi->reset(ctx)把解码器恢复为正常初始化后的状态。
  • 解码器复位之后通过mpp_destroy()释放申请的内存空间,进行一些销毁操作防止内存泄漏。

6. mpi_dec_test使用实例

终端执行解码命令:

sudo mpi_dec_test -i /oem/200frames_count.h264 -t 7 -n 200 -o /oem/decode.yuv -w 1920 -h 1080
  • 其中,-t 7 表示是输入 H.264 码流,-i 表示输入文件,-n 200 表示解码 200 帧 -w 图像宽度 -h 图像高度

解码输出如下:
