I am getting same errors when trying to compile for android |

Get same error when build ios |
|
Hi @dbogdanov can you please help here? this is happening even on normal build from master branch |
|
Okay, so, this persists, and, Essentia desperately needs pre-built libraries because compiling C++ is borderline impossible if you care about your sanity. @dbogdanov Same logs, same error messages, One in here: https://github.com/MTG/essentia/blob/master/src/algorithms/io/audioloader.h#L98 And others here: https://github.com/MTG/essentia/blob/master/src/essentia/utils/audiocontext.cpp#L33 Then we need to downgrade ourselves to version 4 of ffmpeg because there is a
there is only two occurrences of this function call. If I delete both (it is recommended to replace them with nothing), then the How the fuck are we going to find the latest version of ffmpeg 4. X? This is where things get beyond fucked up. In this patch, at, Sept. 15, 2021 from all libraries. So I am picking version 4.4 which released on 2021-04-09 Get the source code: $ wget https://ffmpeg.org/releases/ffmpeg-4.4.tar.xz
$ tar -xf ffmpeg-4.4.tar.xz
$ cd ffmpeg-4.4Then build the ffmpeg yourself: ./configure --disable-doc \

--disable-manpages \
--disable-podpages \
--disable-txtpages \
--pkg-config-flags="--static" \
--ld="g++"sudo make

# compile breaks if i don't remove decklink headers, try yourself before removing
sudo rm libavdevice/decklink*Configure won't throw any errors. If you run You are coming with me. Apply the following patch: https://git.ffmpeg.org/gitweb/ffmpeg.git/commitdiff/effadce6c756247ea8bae32dc13bb3e6f464f0eb with either using patch -i ffmpeg.patchwhere If you want to manually edit, open Change the #define NEG_USR32 NEG_USR32

}then run the makecommand again. If you have no errors, yay, we are in the same state! If make errors out, god save your soul, you are not with me anymore. run sudo make installif you got any errors, good luck, you are out again, if you see something like this when you run the built ffmpeg (essentia) ➜ ffmpeg-4.4.2 ./ffmpeg -version
ffmpeg version 4.4.2 Copyright (c) 2000-2021 the FFmpeg developersThen we are together again, and we are almost there! I say almost, because holy fucking shit, it does not end. Now that we have compiled FFMPEG, we can compile Essentia git clone https://github.com/MTG/essentia.git
cd essentia
python3 waf configure --build-static --with-tensorflowif it is all green python3 wafthere wont be any errors. if, somehow, you got error here, my condolences, you are out of my reach. if you have seen this output run previously, I thought building inside a virtual environment and then moving the include headers + library to the source code folder is the solution, but, if you run the waf install outside of a virtual environment, waf will place all the files to /usr/local/..., and library wont work outside of /usr/local/... Now it is time for GLSLang for libavcodec and various libraries of ffmpeg. git clone https://github.com/KhronosGroup/glslang.git

}change the audio path, configure, compile, run, have fun. tldr: if you don't have any solid reasons, just use python bindings instead. peace. edit: bunch of typos, bad english, poor grammar, pinch me if you dont understand anything |
|
Updates, I have managed to compile CPP library by myself, attached a CMakeLists.txt, if any future readers stumble upon this and follow the comment, let me know if anything goes wrong, I can use Essentia + QT without any problems and fairly fast compilation time. |
On what platform? I couldn't do it on Android 😢 |
|
@Joelcgx can you send the error message? |
Give me time to recompile because I formatted my computer, but the error came when I used the .so in android studio like when using essentia::init |
|
Yee I got you, hit me back with full compile log. Also be sure that you are not using the latest tensorflow libraries, use 2.12 for good measure. I will be here for three hours, i can respond instantly during that timeframe |
Compile FFmpeg 4.4 and EssentiaBelow is the script I used to compile: Script:

|
Is the libraries and headers under /usr/local/lib/libavutil.a latest ffmpeg? They have to be version 4.4 or lower. I dont know how you can determine it, but you should check the FFMPEG library versions first |
I followed those steps ffmpeg --version (Sorry if I'm very stupid or ignorant haha I'm new to this) joelcgx@joelcgx-HP-Compaq-8200-Elite-CMT-PC:~/Documentos/C++/ffmpeg-4.4$ ffmpeg --version

okay then it should all be fine. without doing make install, can you link to the libraries directly instead? like this https://github.com/caner-cetin/conan/blob/ffeb80726685f4421137a6c011bef4c6cf221731/CMakeLists.txt#L158 ffmpeg folder you are in contains all the required library, check relevant parts in my cmake |
I delete using sudo make uninstall and then use cmakelist.txt?? |
|
nonononono, keep the ffmpeg folder and your source folder as it is. are you using make? if yes, move on to the cmake if you can, if not, just replicate what I did with FFMpeg on make. All you have to do is take your ffmpeg folder, which, after you built the ffmpeg, every library folder will contain a binary such as libavcodec folder will have libavcodec.a and so on. As you see in my CMakeLists, I include all of that library folders and all the libraries inside the folders. Dont delete anything, just follow what I did on my CMakeLists. I know its convoluted but you can extract ffmpeg relevant bits fairly easily. |
Ok, I won't delete anything, this is the cmakelist I made, I don't know if it's right, but what do I put in source? A main.cpp (oh god I feel so stupid haha) # Specify the minimum version of CMake

yeeee you going right. dont fill main cpp, just put boilerplate empty main code inside main.cpp, compile, and if it compiles && builds, go into the ffmpeg folder then do in the folder aaaand then compile essentia. you got this mate i believe in youz |

I get this, something went wrong joelcgx@joelcgx-HP-Compaq-8200-Elite-CMT-PC:~/Documentos/C++/ffmpeg-4.4/build$ cmake ..

i understand the cause of error but i never encountered something like this what the fuck. Can you try re launching terminal, sudo make and sudo make install again? I dont know what is wrong because there is clearly a rule for install command in make. |
Well I tried to compile Essentia and it didn't throw an error: joelcgx@joelcgx-HP-Compaq-8200-Elite-CMT-PC:~/Documentos/C++/essentia$ sudo python3 waf build -p -j8

holy shit okay you got this. do and then again you will see essentia on my cmakelists, put it on the correct order related to ffmpeg (above ffmpeg) then compile run report me back |

dont install tensorflow like that change the linux commands (and the filename at tar) with windows equivalent ones, i dont know powershell commands sorry. for ffmpeg, honestly, i dont know mate. try rebuilding doing and then try compiling essentia again, then report back to me, if i dont reply back instantly i will get back to you in 8~ hours because its 7 am and im tired lol beep beep link i sent for tensorflow is dead use this |
dont worry man,It's 10 PM here, rest, I'll try, I'll do the same and thank you, I'll keep you informed |
