ArmSoM-RK3588编解码之mpp解码demo解析：mpi_dec_test

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

• 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：文章来源地址https://www.toymoban.com/news/detail-761473.html
