• Live555 : X264 Stream Live source based on "testOnDemandRTSPServer"

  26 octobre 2017, par user2660369

  I am trying to create a rtsp Server that streams the OpenGL output of my program. I had a look at How to write a Live555 FramedSource to allow me to stream H.264 live, but I need the stream to be unicast. So I had a look at testOnDemandRTSPServer. Using the same Code fails. To my understanding I need to provide memory in which I store my h264 frames so the OnDemandServer can read them on Demand.

• Cant link against ffmpeg with openssl using cmake

  24 mars 2017, par David Barishev

  I have build ffmpeg libraries statically for x86 android using a custom configuration.Now i wanted to add them in my android project.

  Im using ffmpeg 3.2.git, android studio 2.3.

  I created a folder named distribution which had my binaries, and the minimum headers i needed for it to not tell me about missing header (Except for the avutil- i just included them all), located the root of my project.
  I edited my cmake to include the libraries :

  add_library(
  
           native-lib
  
           SHARED
  
           src/main/cpp/native-lib.cpp )
  
  
  
  set(distribution_DIR ${CMAKE_SOURCE_DIR}/../distribution)
  
  
  
  add_library(lib_avcodec STATIC IMPORTED)
  
  set_target_properties(lib_avcodec PROPERTIES IMPORTED_LOCATION
  
      ${distribution_DIR}/libavcodec/lib/${ANDROID_ABI}/libavcodec.a)
  
  
  
  add_library(lib_avfilter STATIC IMPORTED)
  
  set_target_properties(lib_avfilter PROPERTIES IMPORTED_LOCATION
  
      ${distribution_DIR}/libavfilter/lib/${ANDROID_ABI}/libavfilter.a)
  
  
  
  add_library(lib_avformat STATIC IMPORTED)
  
  set_target_properties(lib_avformat PROPERTIES IMPORTED_LOCATION
  
      ${distribution_DIR}/libavformat/lib/${ANDROID_ABI}/libavformat.a)
  
  
  
  add_library(lib_avutil STATIC IMPORTED)
  
  set_target_properties(lib_avutil PROPERTIES IMPORTED_LOCATION
  
      ${distribution_DIR}/libavutil/lib/${ANDROID_ABI}/libavutil.a)
  
  
  
  add_library(lib_swresample STATIC IMPORTED)
  
  set_target_properties(lib_swresample PROPERTIES IMPORTED_LOCATION
  
      ${distribution_DIR}/libswresample/lib/${ANDROID_ABI}/libswresample.a)
  
  
  
  
  
  include_directories(
  
                            ${distribution_DIR}
  
                            )
  
  
  
  find_library( # Sets the name of the path variable.
  
            z-lib
  
  
  
            # Specifies the name of the NDK library that
  
            # you want CMake to locate.
  
            z )
  
  
  
  target_link_libraries( 
  
                     native-lib
  
  
  
                     ${z-lib}
  
  
  
                     lib_crypto
  
                     lib_ssl
  
  
  
                     lib_avfilter
  
                     lib_avformat
  
                     lib_avcodec
  
                     lib_swresample
  
  
  
                     lib_avutil
  
  
  
                      )

  I also restricted the build to only x86, in my app build.gradle :

  ndk {
  
              // Specifies the ABI configurations of your native
  
              // libraries Gradle should build and package with your APK.
  
              abiFilters 'x86'
  
      }

  The project gradle sync worked successfully.
  I wrote the following code in my cpp file :

  #include 
  
  
  
  
  
  extern "C"{
  
      #include "libavformat/avformat.h"
  
  }
  
  JNIEXPORT void JNICALL
  
  Java_com_example_david_testffmpegcpp_MainActivity_stringFromJNI(
  
          JNIEnv *env,
  
          jobject /* this */) {
  
  
  
      av_register_all ();
  
      avformat_network_init ();
  
  
  
  
  
  }

  Just to check if the library works, but i cant seem to link against the libraries correctly. It complains about undefined symbols.
  What did i do wrong ?

  EDIT :

  I changed the order of the linked libraries, and was able to remove all error for ffmpeg’s library functions not found, and i added zlib,that removed some more.

  The only error left are those how are related to openssl, its logical since i compiled my ffmpeg libraries with openssl.

  I tried linking my openssl static libraries that i used for compiling ffmpeg like this :

  set(ssl_dir ${CMAKE_SOURCE_DIR}/../../../FFmpegBuild/Openssl/output_19/android)
  
  
  
  add_library(lib_ssl STATIC IMPORTED)
  
  set_target_properties(lib_ssl PROPERTIES IMPORTED_LOCATION
  
      ${ssl_dir}/openssl-${ANDROID_ABI}/lib/libssl.a)
  
  
  
  add_library(lib_crypto STATIC IMPORTED)
  
  set_target_properties(lib_crypto PROPERTIES IMPORTED_LOCATION
  
      ${ssl_dir}/openssl-${ANDROID_ABI}/lib/libcrypto.a) 
  
  
  
  include_directories(      ${ssl_dir}/openssl-${ANDROID_ABI}/include
  
                            ${distribution_DIR}
  
  
  
                            )

  And linked against them :

  target_link_libraries( # Specifies the target library.
  
                         native-lib
  
  
  
                         ${z-lib}
  
  
  
  
  
                         lib_ssl
  
                         lib_crypto
  
  
  
                         lib_avfilter
  
                         lib_avformat
  
                         lib_avcodec
  
                         lib_swresample
  
  
  
                         lib_avutil
  
  
  
                          )

  But i’m still getting the error that i state below.
  My question is why ? Also if i already built ffmpeg in static mode, how come i need to relink openssl again ?

• ffmpeg : init filtergraphs only after we have a frame on each input

  27 mai 2016, par Anton Khirnov

  ffmpeg : init filtergraphs only after we have a frame on each input
  This makes sure the actual stream parameters are used, which is
  
  important mainly for hardware decoding+filtering cases, which would
  
  previously require various weird workarounds to handle the fact that a
  
  fake software graph has to be constructed, but never used.
  
  This should also improve behaviour in rare cases where
  
  avformat_find_stream_info() does not provide accurate information.
  This merges Libav commit a3a0230. It was previously skipped.
  The code in flush_encoders() which sets up a "fake" format wasn’t in
  
  Libav. I’m not sure if it’s a good idea, but it tends to give
  
  behavior closer to the old one in certain corner cases.
  The vp8-size-change gives different result, because now the size of
  
  the first frame is used. libavformat reported the size of the largest
  
  frame for some reason.
  The exr tests now use the sample aspect ratio of the first frame. For
  
  some reason libavformat determines 0/1 as aspect ratio, while the
  
  decoder returns the correct one.
  The ffm and mxf tests change the field_order values. I’m assuming
  
  another libavformat/decoding mismatch.
