CMakeLists.txt 修改成自己编译的ffmpeg后，detect.sh中read_engine=opencv可以识别但是只有7-8的FPS，read_engine=opencv会显示

[h264_rkmpp @ 0x55a10d5fb0] Doing slow software conversion
Failed to convert YUV420SP to BGR
RgaBlit(1483) RGA_BLIT fail: Invalid argument
RgaBlit(1484) RGA_BLIT fail: Invalid argument

下面是修改后的CMakeLists.txt

cmake_minimum_required(VERSION 3.4.1)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

可执行文件名

project(${CMAKE_USER_APP_NAME})

设置编译器标志

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread")

skip 3rd-party lib dependencies

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,--allow-shlib-undefined")

install target and libraries

set(CMAKE_INSTALL_PREFIX ${CMAKE_USER_INSTALL_PREFIX})
set(CMAKE_SKIP_INSTALL_RPATH FALSE)
set(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)

用于指定程序运行时查找动态链接库的路径

set(CMAKE_INSTALL_RPATH ${CMAKE_USER_LIBRARY_PATH};${CMAKE_USER_LIBRARY_PATH}/ffmpeg)

lib and include path

link_directories(${CMAKE_USER_LIBRARY_PATH})
include_directories(${CMAKE_USER_INCLUDE_PATH})

添加 pkg-config，查找系统 FFmpeg 安装的路径

find_package(PkgConfig REQUIRED)
pkg_check_modules(FFMPEG REQUIRED libavcodec libavformat libavutil libswscale)

添加 FFmpeg 头文件和库路径

include_directories(${FFMPEG_INCLUDE_DIRS})
link_directories(${FFMPEG_LIBRARY_DIRS})

设置 FFmpeg 库

set(FFMPEG_LIBS ${FFMPEG_LIBRARIES})

rknn api

set(RKNN_RT_LIB librknnrt.so)
include_directories(${CMAKE_USER_INCLUDE_PATH}/rknn)

rga

set(RGA_LIB librga.so)
include_directories(${CMAKE_USER_INCLUDE_PATH}/rga)

opencv

find_package(OpenCV REQUIRED)
message(STATUS "**** OpenCV find: ${OpenCV_VERSION} ****")

video reader

include_directories(${CMAKE_USER_INCLUDE_PATH}/reader)

匹配 src 目录下的所有 .cpp 文件

file(GLOB SRC_FILES "src/*.cpp")

匹配 src/reader 目录下的所有 .cpp 文件

file(GLOB READER_FILES "src/reader/*.cpp")

将列表合并

set(ALL_SRC_FILES ${SRC_FILES} ${READER_FILES})

编译可执行文件

add_executable(${CMAKE_USER_APP_NAME} ${ALL_SRC_FILES})

链接库

target_link_libraries(${CMAKE_USER_APP_NAME}
${RKNN_RT_LIB}
${RGA_LIB}
${OpenCV_LIBS}
${FFMPEG_LIBS}
)

install target and libraries

install(TARGETS yolov5_muti DESTINATION ./)

install(PROGRAMS ${RKNN_RT_LIB} DESTINATION lib)

install(PROGRAMS ${RGA_LIB} DESTINATION lib)

install(PROGRAMS ${FFMPEG_LIBS} DESTINATION lib)

install(DIRECTORY model DESTINATION ./)
