8 years ago Hi @carthach ,
Thank you for letting me know that. From this line in the console log:
- FFmpeg (or LibAv on debian/ubuntu) seems to be missing.
The following algorithms will be ignored: ['AudioLoader', 'MonoLoader', 'EqloudLoader', 'EasyLoader', 'MonoWriter', 'AudioWriter']I understand that no audio loader will be available if i compile essentia without ffmpeg. Is it correct? If ffmpeg is required, so why the document here said that ffmpeg is optional?
Thank you, Tien.

8 years ago "libavcodec/libavformat/libavutil/libavresample (from the FFmpeg/LibAv project): for loading/saving any type of audio files (optional)".
It's optional but as the documentation says if you don't use it you won't be able to do any loading/saving of audio files. Some of us use Essentia with frameworks like JUCE and openFrameworks, in which case we use their own audio I/O features and compile a reduced version of Essentia without FFmpeg.

8 years ago I got it. It means I have to compile essentia with ffmpeg in order to use essentia in iOS. Thank you much, @carthach

8 years ago Note that if are not obliged to use ffmpeg. You can load audio using native iOS methods and then do analysis in Essentia.

8 years ago I had build the ios library successfully by the recommended command.
But I needed MonoLoader for read audio file, so I remove the --lightweight in recommended command, and I run it as follow in macOS:
./waf configure --cross-compile-ios --fft=ACCELERATE --build-static
The output is:
LogicdeMacBook-Pro:essentia logic$ ./waf configure --cross-compile-ios --fft=ACCELERATE --build-static

'configure' finished successfully (0.278s)It created static lib successfully, but some errors occurred in xcode when I used it:
Hello,
I have just compiled essentia for iOS and now I'm trying to create an iOS example follow this tutorial: http://essentia.upf.edu/documentation/howto_standard_extractor.html
The problem is when I run my project, it said that MonoLoader is not available. It seem that no audio loader is available in my essentia binary.
Here is the log of Xcode:
