[Clam-devel] pyclam: CLAM python bindings (some preliminary results)
Hi all, Recently I been playing a little with Boost.Python and CLAM library and I'd like to show you the results: By now I was able to parse with sucess only a subset of clam classes and the problems that arose with basic ones were temporary solved with a couple of workarounds (especially because dynamic types), but I believe those issues could be solved in a better way with more work on it. If you agree and like the idea, let me know and i'll upload my work to the repo along with some instrucctions to get it running. This is how the python code looks like at the moment: (fft_example.py) import clam from math import sin samples = 1024 sampleRate = 8000.0 sineFreq = 400.0 myaudio = clam.Audio() myaudio.SetSize( samples ); myaudio.SetSampleRate( sampleRate ); vector = myaudio.GetBuffer() for i in range(samples): vector.set( i, 0.625+0.5*sin(2.0*sineFreq*400.0*((float(i))/sampleRate)) ) #print vector[i] myspectrum = clam.Spectrum() specFlags = clam.SpecTypeFlags() specFlags.SetFlag( specFlags.GetFlagPosition(Polar), 1 ) specFlags.SetFlag( specFlags.GetFlagPosition(Complex), 1 ) specFlags.SetFlag( specFlags.GetFlagPosition(MagPhase), 1 ) specFlags.SetFlag( specFlags.GetFlagPosition(Polar), 1 ) specFlags.SetFlag( specFlags.GetFlagPosition(MagPhaseBPF), 1 ) myspectrum.SetType( specFlags ) myspectrum.SetSize( samples/2+1 ) fconfig = clam.FFTConfig() fconfig.SetAudioSize( samples ) myfft = clam.FFT_ooura() myfft.Configure( fconfig.getReal() ) myfft.Start() print Running object myfft.Do( myaudio.getBase(), myspectrum.getBase() ) print Storing spectrum clam.XmlStorage.Dump( clam.toComponent(myspectrum), FFTResult, pyFFT_example.xml) -- Other example: (playfile.py) import clam import time filename = ./test30seg.mp3 network = clam.Network() reader = network.AddProcessing( MonoAudioFileReader ) config = clam.MonoAudioFileReaderConfig() config.SetSourceFile( filename ) if not network.ConfigureProcessing(reader, config): print Could not open the file sink = network.AddProcessing( AudioSink ) network.ConnectPorts( reader+.Samples Read, sink+.AudioIn ) portaudio_player = clam.PANetworkPlayer() network.SetPlayer( portaudio_player ); network.Start() time.sleep( clam.MonoAudioFileReader( network.GetProcessing(reader) ).GetLength() ) network.Stop() -- The current available namespace of clam bindings: clam.Audio clam.MonoAudioFileReaderclam.__file__ clam.Component clam.MonoAudioFileReaderConfig clam.__getattribute__ clam.ConnectControlsclam.Networkclam.__hash__ clam.ConnectPorts clam.NetworkPlayer clam.__init__ clam.ConnectTypedControls clam.PANetworkPlayerclam.__name__ clam.DataArray clam.Processing clam.__new__ clam.EFFTType clam.ProcessingConfig clam.__reduce__ clam.Enum clam.ProcessingData clam.__reduce_ex__ clam.Errclam.SendFloatToInControl clam.__repr__ clam.ErrNotFoundclam.SendFloatToOutControl clam.__setattr__ clam.FFTclam.SpecTypeFlags clam.__str__ clam.FFTConfig clam.Spectrum clam.eFFT_IUA clam.FFT_base clam.Storageclam.eFFT_NREC clam.FFT_ooura clam.XmlStorage clam.eNone clam.FlagsBase clam.__class__ clam.eRFFTW clam.Flags_less__4u__grate_ clam.__delattr__clam.so clam.GetFloatFromInControl clam.__dict__ clam.toComponent clam.IllegalValue clam.__doc__ Let me know.

Wow, all that working in python seems amazing to me. Great work, Hernan! Could you sent a tarball/patch? i want to play with it. :-) David.

6mb is to much load i would prefer the files to compile it + instructions. I can wait.

Great work, Hernan! Could you sent a tarball/patch? i want to play with it. :-) I'll send you the compiled .so (about 6mb) to test it just put it in the same dir of the python script (or where you run the python as interpreter or ipython). Then I'll prepare some instructions in order to allow you compile it by your own (beside boost.python other tools are needed like py++ and gccxml) along with the tarball of the project. ___ Clam-devel mailing list Clam-devel@llistes.projectes.lafarga.org https://llistes.projectes.lafarga.org/cgi-bin/mailman/listinfo/clam-devel

Re: [Clam-devel] pyclam: CLAM python bindings (some preliminary results)
Hi again, I prepared a tarball[1], see the README file for instructions. Most problems and issues are commented and explained inside the code (don't worry, the project are a few files) Some notes: * As said is a subset of classes, i was increasing the code base step by step and i think i can continue in the same way. * I had to do a simple wrap to some classes since dynamic types brought me problems with the parse and bindings (like audio or spectrum) * It's a pity i couldn't get it working the original Array class because the way is implemented (with pointers and by hand memory allocation) since std::vectors bindings to numpy vectors works nearly from scratch. I managed to get working a wrap with the [] operator, but no supports assigment at the moment (the workaround is the set method). * I was able to parse SpecTypeFlags and Flags classes but couldn't get working a binding to a std::bitset in python. The workaround is use specFlags.SetFlag( specFlags.GetFlagPosition(Polar), 1 ) instead of specFlags.bPolar=1 * Other things i can't remember at the moment :-D, just check the project files! Of course, there are a lot of things to improve, is just a preliminary approach with the mind in have a couple of examples working, not more.
