RK3588 Encoding and Decoding Analysis of Mpp Decoding Demo: mpi_dec_test

1. Introduction

mpi_dec_test is the official decoding demo from Rockchip
This article analyzes the code and decoding flow of mpi_dec_test

2. Environment Introduction

Hardware environment:
ArmSoM-W3 RK3588 Development Board
Software version:
OS: ArmSoM-Sige7 Debian11

3. Mpp Decoding Flow Analysis

mpp1

mpp_create: get MppCtx instance and MppApi structure
mpp_init: init decoding type and format of MppCtx
mpi->control: configure decoding parameters through commands
decode_put_packet: input stream: encoded data MppPacke, e.g. H264, H265 data
decode_get_frame: get decoded data stored in MppFrame, e.g. YUV, RGB data
mpi->reset: reset decoder to normal initialized status
mpp_destroy: release allocated memory, destroy properly

4. Important Function Analysis

mpp_init function: init decoding type and format of MppCtx

Prototype of mpp_init function:

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

Instance of calling mpp_init function:

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;  
 }

Parameter analysis of mpp_init function:

MppCtxType parameter: init encoder or decoder

MPP_CTX_DEC : decoder   
MPP_CTX_ENC : encoder

MppCodingType parameter: coding format

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 Flow Analysis

mpi_dec_test decode command example:

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

mpi_dec_test flow analysis:

main() ---> dec_decode() ---> thread_decode() ---> dec_simple() ---> mpp_destroy()

The main function parses parameters based on input cmd params (cmd param char **argv corresponds to command -i /oem/200frames_count.h264 -t 7 -n 200 -o /oem/decode.yuv -w 1920 -h 1080) and saves to structure MpiDecTestCmd *cmd
dec_decode(cmd) is the encapsulated decoding function. Pass in structure MpiDecTestCmd * cmd to complete decoding
Function dec_decode executes some MPP init operations: mpp_create() mpp_init(), mpp_dec_cfg_init(), mpi->control. After init, create decode thread: thread_decode to decode.
Decode thread: thread_decode thread judges whether to use dec_simple decoding or dec_advanced decoding based on variable cmd->simple
After decoding the last frame, execute pthread_join() function to wait for thread_decode： thread_decode to end and release thread
After thread release, execute reset : mpi->reset(ctx) reset decoder to normal initialized status.
After decoder reset, release allocated memory through mpp_destroy(), some destroy operations to prevent memory leak.

6. mpi_dec_test Usage Example

Execute decode command in terminal:

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

Analysis of command: -t 7: input H.264 stream, -i :input file, -n 200 :decode 200 frames, -w :image width, -h :image height

Decode output as below:
