• libavdevice : Improve example in deprecation message for opengl and sdl

  8 avril 2024, par Alexander Strasser

  libavdevice : Improve example in deprecation message for opengl and sdl
  When piping ffmpeg into ffplay both programs write a status line in
  
  the terminal. That causes flickering and invisibility of one or the
  
  other status line.
  As compromise set ffplay log level to warning, so it doesn't show
  
  the status line.
  The user is usually testing ffmpeg command lines and want's a
  
  preview of the result. This way the user can see the ffmpeg output
  
  and still see errors and warnings from ffplay, should they occur.
  Additionally set PTS to zero in ffplay to lessen the delay until
  
  the frames are displayed. Without it delay is quite observable
  
  when e.g. live capturing with low frame rates.

• how to resolve Linking error undefined reference to symbol 'avcodec_open2@@LIBAVCODEC_54

  20 septembre 2016, par TobSta

  I’m getting the following linking error

  Linking CXX executable test_decode
  
  /usr/bin/ld: /home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG/libWrapFFMPEG.a(DecodeFFMPEG.cpp.o): undefined reference to symbol 'avcodec_open2@@LIBAVCODEC_54'
  
  //usr/lib/x86_64-linux-gnu/libavcodec.so.54: error adding symbols: DSO missing from command line
  
  collect2: error: ld returned 1 exit status
  
  make[2]: *** [test_decode] Error 1
  
  make[1]: *** [CMakeFiles/test_decode.dir/all] Error 2
  
  make: *** [all] Error 2

  cmake . && make works for WrapFFMPEG, but for test_decode, i get the linking error when building

  My CMakeLists.txt for test_decode :

  cmake_minimum_required (VERSION 2.8)
  
  #cmake_policy(SET CMP0003 OLD)
  
  
  
  # Add executable
  
  add_executable(test_decode test_decode.cpp)
  
  
  
  find_package(OpenCV REQUIRED )
  
  message(STATUS ${OPENCV_INCLUDE_DIRS})
  
  include_directories (${OPENCV_INCLUDE_DIRS},      "/home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG")
  
  find_library (WrapFFMPEG WrapFFMPEG "/home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG")
  
  
  
  
  
  message(STATUS ${WrapFFMPEG})
  
  link_directories( ${WrapFFMPEG} )
  
  
  
  
  
  # Link to the WrapFFMPEG library
  
  target_link_libraries(test_decode LINK_PUBLIC ${OpenCV_LIBRARIES} ${WrapFFMPEG})
  
  
  
  add_custom_command(TARGET test_decode POST_BUILD COMMAND xcopy /i /y \"${FFmpeg_RUNTIME_LIBS}\" \"${CMAKE_CURRENT_BINARY_DIR}\")

  and my CMakeLists.txt for WrapFFMPEG :

  cmake_minimum_required (VERSION 2.8)
  
  file(GLOB sources *.cpp *.h)
  
  
  
  list(APPEND CMAKE_MODULE_PATH "/home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG")
  
  
  
  find_package( avformat REQUIRED)
  
  find_package( avcodec REQUIRED)
  
  find_package( avutil REQUIRED )
  
  find_package( swscale REQUIRED )
  
  
  
  include_directories(    
  
  ${AVFORMAT_INCLUDE_DIR}
  
  ${AVCODEC_INCLUDE_DIR}
  
  ${AVUTIL_INCLUDE_DIR}
  
  ${SWSCALE_INCLUDE_DIR}
  
  )
  
  
  
  
  
  set( 
  
  FFMPEG_LIBRARIES    
  
  ${AVFORMAT_LIBRARY}
  
  ${AVCODEC_LIBRARY}
  
  ${AVUTIL_LIBRARY}
  
  ${SWSCALE_LIBRARY}
  
  )
  
  
  
  add_library(WrapFFMPEG ${sources})
  
  
  
  #add_library(WrapFFMPEG DecodeFFMPEG.cpp DecodeFFMPEG.h )
  
  set(FFMPEG_INCLUDE_DIR     "/home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG/ffmpeg")
  
  find_library (FFMPEG FFMPEG "/home/t/NetBeansProjects/FaceCept3D/WrapFFMPEG/ffmpeg")
  
  message(STATUS ${FFMPEG_LIBRARIES})
  
  message(STATUS ${FFMPEG})
  
  include_directories($(FFMPEG_INCLUDE_DIR}))
  
  message(STATUS ${FFMPEG_INCLUDE_DIR})
  
  
  
  
  
  # Make sure the compiler can find include files for our WrapFFMPEG library
  
  # when other libraries or executables link to WrapFFMPEG
  
  target_include_directories (WrapFFMPEG PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})
  
  target_link_libraries(WrapFFMPEG avutil avcodec avformat swscale)

  resulting in link.txt :

  /usr/bin/ar cq libWrapFFMPEG.a CMakeFiles/WrapFFMPEG.dir/DecodeFFMPEG.cpp.o CMakeFiles/WrapFFMPEG.dir/Tutorial.cpp.o /usr/bin/ranlib libWrapFFMPEG.a

  did CMake not find ffmpeg ?
