• I can't compile ffmpeg, don't know how to install sdl2 properly

  11 mai 2019, par woopwoop399

  I’m compiling ffmpeg, on windows, with mingw-w64, and I need SDL2 so that the ffplay in ffmpeg compiles. I installed mingw-w64 using the web installer, I installed msys (to run the ./configure that comes with ffmpeg) using the all in one package provided by mingw-w64. I installed SDL2 by downloading dev binaries from their site and running make native in msys.

  So, it seems SDL2 isn’t installed properly or something.

  Here is the problematic part in ./configure :

  if enabled sdl2; then
  
      echo "SDL2-1"
  
      SDL2_CONFIG="${cross_prefix}sdl2-config"
  
      test_pkg_config sdl2 "sdl2 >= 2.0.1 sdl2 < 2.1.0" SDL_events.h SDL_PollEvent
  
      echo "SDL2-2"
  
      if disabled sdl2 && "${SDL2_CONFIG}" --version > /dev/null 2>&1; then
  
          echo "SDL2-3"
  
          sdl2_cflags=$("${SDL2_CONFIG}" --cflags)
  
          sdl2_extralibs=$("${SDL2_CONFIG}" --libs)
  
          echo "SDL2-config ${SDL2_CONFIG}"
  
          echo "SDL2-cflags ${sdl2_cflags}"
  
          echo "SDL2-libs ${sdl2_extralibs}"
  
          test_cpp_condition SDL.h "(SDL_MAJOR_VERSION<<16 | SDL_MINOR_VERSION<<8 | SDL_PATCHLEVEL) >= 0x020001" $sdl2_cflags &&
  
          echo "SDL2-4" &&
  
          test_cpp_condition SDL.h "(SDL_MAJOR_VERSION<<16 | SDL_MINOR_VERSION<<8 | SDL_PATCHLEVEL) < 0x020100" $sdl2_cflags &&
  
          echo "SDL2-5" &&
  
          check_func_headers SDL_events.h SDL_PollEvent $sdl2_extralibs $sdl2_cflags &&
  
          echo "SDL2-6-final" &&
  
              enable sdl2
  
      fi
  
      if test $target_os = "mingw32"; then
  
          sdl2_extralibs=$(filter_out '-mwindows' $sdl2_extralibs)
  
      fi
  
  fi

  This is the result of it, it never gets to SDL2-6-final and enable sdl2

  SDL2-1
  
  SDL2-2
  
  SDL2-3
  
  SDL2-config sdl2-config
  
  SDL2-cflags -I/usr/include/SDL2 -Dmain=SDL_main
  
  SDL2-libs -L/usr/lib -lmingw32 -lSDL2main -lSDL2 -mwindows
  
  SDL2-4
  
  SDL2-5

  This is the sdl2 installation log :

  And this is what happens when I just comment out that last check in ./configure and enable sdl2 anyway :

  I tried using msys2 instead, it compiles, but the debugger there doesn’t work for some reason. I need to run the source code of ffmpeg in debugger to have a chance of understanding anything there. I need to use the combination of codeblocks and gdb, and programs compiled with msys2 use weird pathnames like /c/bla/bla/bla/main.c, and codeblocks is righteously weirded out by that. The mingw-w64 uses more sane pathnames, I just checked that.

  Checked ffbuild/config.log, the problem is here :

• FFmpeg mosaic video creation, Why it doesn't work ?

  3 mai 2019, par Ege Darçın

  I am trying to build a mosaic from multiple videos in an android application using FFmpeg, I have found the wiki on how to do it. The link explains the process well but I am getting this error while processing it :

  I/Videokit : start run in main.

  register_exit

  term_init & parse options.

  D/Videokit : ERROR OCCURED

  The library that I’m using is WritingMinds, which is FFmpeg for Android compiled with x264, libass, fontconfig, freetype, fribidi and lame (Supports Android 4.1+). Basically, you write a string array of code which is passed to FFmpeg and it runs FFmpeg for you.

  Clearly, it is a parsing error but I believe that I have put the command in order. I have tested the files, locations and FFmpeg with other commands like trim, mute audio etc and only mosaic doesn’t work. I have tried different options, string manipulations but that didn’t work, Furthermore, I’ve seen OpenGl error if I put a big typo error.
  Here is the code on the wiki :

                  FinalPath.toString()};
  
                  execFFmpegBinary(m);

  This is the string that I send to the FFmpeg.

  The expected result would be a video created on the "FinalPath" which is on the external storage. However, I am getting an error message and nothing else. I have a tight deadline so it would be hard for me to switch to another system and learn it, I’m already new to FFmpeg stuff. Any suggestions ?

  Update : I’ve implemented error handlers of the library, not just FFmpeg part, and it points reports as (’"nullsrc’ is not a filter) . However, I need to put (") into there to run the code and I use it as (\"), which does not solve the problem. Removing them is not an option because the statement after the filter needs the quotation marks.

  Update2 : Here is the current log :

• Android : FFMpeg (video creation) crashes with no exception when loading binaries in lower APIs (18 in my case) but works in newer ones

  6 mai 2019, par Diego Perez

  I have an app that uses FFMpeg for video creation (these next lines are the relevant build.gradle plugin files) :

  //writingminds
  
  api 'com.writingminds:FFmpegAndroid:0.3.2'
  
  //JavaCV video
  
  api group: 'org.bytedeco', name: 'javacv', version: '1.4.4'
  
  api group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '4.0.1-1.4.4', classifier: 'android-arm'
  
  api group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '4.1-1.4.4', classifier: 'android-arm'

  And my app is working (and creating video) just fine in my phone with a newer Android 8 version but I’m having weird problems in my old API 18 tablet (where, as a note, I had to install multidex).

  These next lines are the main part of FFMpeg video creation, where binaries are loaded, and, in fact, binaries load are where app crashes in my tablet in the line "ffmpeg.loadBinary(new LoadBinaryResponseHandler()..."

  As you can see, I have a try/catch where the app crashes, but it crashes with no aparent exception, as catch blocks are never hit.

  public static String recordVideo(JSONObject objJSON) {
  
  
  
      String strReturn = Enum.Result.OK;
  
  
  
      try {
  
          fileName = objJSON.has("file_name") ? String.valueOf(objJSON.getString("file_name")) : "";
  
          videoPath = objJSON.has("video_path") ? String.valueOf(objJSON.getString("video_path")) : "";
  
      } catch (JSONException e) {
  
          ExceptionHandler.logException(e);
  
      }
  
  
  
      FFmpeg ffmpeg = FFmpeg.getInstance(ApplicationContext.get());
  
      try {
  
          ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {}
  
  
  
              @Override
  
              public void onFailure() {}
  
  
  
              @Override
  
              public void onSuccess() {}
  
  
  
              @Override
  
              public void onFinish() {}
  
          });
  
      } catch (FFmpegNotSupportedException e) {
  
          // Handle if FFmpeg is not supported by device
  
      } catch (Exception e) {
  
  
  
      }
  
  ...

  These next lines are the relevant part of the LogCat, but I cannot figure out where the problem resides, maybe an out of memory problem ?

  Any help will be much appreciated.

  Edit 1 :

  Still investigating and entered FFmpeg.java to the method loadBinary while debugging, which code I’ll paste below and the line making the crash is switch (CpuArchHelper.getCpuArch())

  @Override
  
  public void loadBinary(FFmpegLoadBinaryResponseHandler ffmpegLoadBinaryResponseHandler) throws FFmpegNotSupportedException {
  
      String cpuArchNameFromAssets = null;
  
      switch (CpuArchHelper.getCpuArch()) {
  
          case x86:
  
              Log.i("Loading FFmpeg for x86 CPU");
  
              cpuArchNameFromAssets = "x86";
  
              break;
  
          case ARMv7:
  
              Log.i("Loading FFmpeg for armv7 CPU");
  
              cpuArchNameFromAssets = "armeabi-v7a";
  
              break;
  
          case NONE:
  
              throw new FFmpegNotSupportedException("Device not supported");
  
      }
  
  
  
      if (!TextUtils.isEmpty(cpuArchNameFromAssets)) {
  
          ffmpegLoadLibraryAsyncTask = new FFmpegLoadLibraryAsyncTask(context, cpuArchNameFromAssets, ffmpegLoadBinaryResponseHandler);
  
          ffmpegLoadLibraryAsyncTask.execute();
  
      } else {
  
          throw new FFmpegNotSupportedException("Device not supported");
  
      }
  
  }

  I’ll keep on investigating...

  Edit 2 :

  Further debugging has just lead me to the exact line where app crashes, and it’s CpuArchHelper.java from FFmpeg library :

  The line causing the crash is the next :

  String archInfo = cpuNativeArchHelper.cpuArchFromJNI();

  and I cannot even go inside cpuArchFromJNI() with F7 as it just crashes.

  package com.github.hiteshsondhi88.libffmpeg;
  
  
  
  import android.os.Build;
  
  
  
  class CpuArchHelper {
  
  
  
      static CpuArch getCpuArch() {
  
          Log.d("Build.CPU_ABI : " + Build.CPU_ABI);
  
          // check if device is x86 or x86_64
  
          if (Build.CPU_ABI.equals(getx86CpuAbi()) || Build.CPU_ABI.equals(getx86_64CpuAbi())) {
  
              return CpuArch.x86;
  
          } else {
  
              // check if device is armeabi
  
              if (Build.CPU_ABI.equals(getArmeabiv7CpuAbi())) {
  
                  ArmArchHelper cpuNativeArchHelper = new ArmArchHelper();
  
                  String archInfo = cpuNativeArchHelper.cpuArchFromJNI();
  
                  // check if device is arm v7
  
                  if (cpuNativeArchHelper.isARM_v7_CPU(archInfo)) {
  
                      // check if device is neon
  
                      return CpuArch.ARMv7;
  
                  }
  
                  // check if device is arm64 which is supported by ARMV7
  
              } else if (Build.CPU_ABI.equals(getArm64CpuAbi())) {
  
                  return CpuArch.ARMv7;
  
              }
  
          }
  
          return CpuArch.NONE;
  
      }
  
  
  
      static String getx86CpuAbi() {
  
          return "x86";
  
      }
  
  
  
      static String getx86_64CpuAbi() {
  
          return "x86_64";
  
      }
  
  
  
      static String getArm64CpuAbi() {
  
          return "arm64-v8a";
  
      }
  
  
  
      static String getArmeabiv7CpuAbi() {
  
          return "armeabi-v7a";
  
      }
  
  }

  This is ArmArchHelper.java class :

  package com.github.hiteshsondhi88.libffmpeg;
  
  
  
  class ArmArchHelper {
  
      static {
  
          System.loadLibrary("ARM_ARCH");
  
      }
  
  
  
      native String cpuArchFromJNI();
  
  
  
      boolean isARM_v7_CPU(String cpuInfoString) {
  
          return cpuInfoString.contains("v7");
  
      }
  
  
  
      boolean isNeonSupported(String cpuInfoString) {
  
          // check cpu arch for loading correct ffmpeg lib
  
          return cpuInfoString.contains("-neon");
  
      }
  
  
  
  }

  Edit 3 :

  Reading carefully LogCat I’ve noticed there is a TransactionTooLarge Exception :

  04-28 21:44:46.103 450-13973/? W/ActivityManager: Exception thrown during pause

          at com.android.server.am.NativeCrashListener$NativeCrashReporter.run(NativeCrashListener.java:86)

  Maybe this is what makes my app to crash, but I don’t know what to do with that, as it happens inside the FFMpeg library :s

  Edit 3 :

  As a note, I’ve tried in an old Android 4.2.2 (API 17) phone I also own and it’s working just fine, the video is generated without crashing.
