ni-media's Introduction

NI MEDIA

NI Media is a library for reading from / writing to audio streams developed at Native Instruments.

Motivation

The goal is to have a modern C++ library for dealing with audio streams in an idiomatic C++ style.

Modern:

a clear separation of concerns (modular instead of fat classes)
support for ranges and iterators

Idiomatic:

based on std.streams.
integrates well with STL algorithms and boost

The following example demonstrates how to stream an entire audio file into a vector:

#include <ni/media/audio/ifstream.h>
#include <vector>

int main()
{
    auto stream = audio::ifstream("hello.wav");
    auto samples = std::vector<float>(stream.info().num_samples());
    stream >> samples;
    // use samples
}

Components

audiostream: the main library for reading from / writing to audio streams.
pcm: a small library to convert pcm data from / to arithmetic types.

Dependencies

boost ( algorithm, endian, filesystem, format, icl, iostream, local, math, program-option, regex, system)
flac & ogg, for flac support (CMake option NIMEDIA_ENABLE_FLAC_DECODING)
vorbis & ogg, for ogg vorbis support (CMake option NIMEDIA_ENABLE_OGG_DECODING)
googletest for building the tests (CMake option NIMEDIA_TESTS)

Platforms

ni-media requires a c++14 compliant compiler and is currently supported and tested on these platforms:

Windows ( requires Visual Studio 2015 Update 3 or higher )
Mac OS X ( requires Xcode / Clang 7.3 or higher )
iOS ( requires Xcode / Clang 7.3 or higher )
Linux ( requires GCC 5.0 or higher, Clang 7.3 or higher should also work )

Building

First, build and install boost filesystem, iostream, system and program-option to path/to/dependencies. Optionally install any codecs that you want to use, for example flac and ogg-vorbis. Now configure ni-media with CMake (version 3.16.0 or higher is required)

cmake -G YOUR-PROJECT-GENERATOR -DCMAKE_PREFIX_PATH=path/to/dependencies/ path/to/ni-media

Specific codecs can be enabled / disabled by passing additional CMake options.

We can now build ni-media:

cmake --build .

Testing

googletest is required for testing and needs to be installed to path/to/dependencies. The unit tests can be enabled with CMake option NIMEDIA_TESTS.

cmake -G YOUR-PROJECT-GENERATOR -DCMAKE_PREFIX_PATH=path/to/dependencies/ -DNIMEDIA_TESTS=ON path/to/ni-media

Before running the tests some reference test files need to be downloaded using git-lfs:

git lfs pull -X ""

To execute the tests run:

cmake --build . --target test

ni-media's Issues

Flaky ifstream tests with Windows Media Foundation

We have randomly failing ifstream tests when using wmf's mp3 decoders. Let's figure out why.

Supported File Formats

I just used libsndfile for a library, but this looks like a great contender.

Is there documentation on what formats are supported? I could find wav and aiff subfolders, and now I am guessing those are the supported file formats?

Compiler warning in positioning.h

/home/wolfv/Programs/ni-media/audiostream/src/ni/media/iostreams/positioning.h:35:14: warning: enumeration value '_S_ios_seekdir_end' not handled in switch [-Wswitch]

As it's the only warning and seems easy to solve, would be nice! :)

Getting the exact number of frames from a stream

Hi There !

We're investigating how to handle loading wav files whose size - as declared in the RIFF header - is incorrect and a lot larger than the data actually contained in the file.

In such cases, we would like to crop the sound to the actual data and ideally, be able to determine the exact size without having to read the whole file upfront.

As expected, ifstream::num_frames will return the value read in the header.

However, the documentation states:

num_frames may differ from the actual number of frames in the stream
as this information relies on the codec. The only way to obtain the exact
number of frames is by seeking to the end of stream and retrieving the frame position.

So, we're trying to use ifstream::frame_tellg but it seems to return the same value as num_frame.

Here's an example code that evaluates the number of frame using num_frames, frame_seekg and by reading the data,.

  // Build a ifstream
  const auto filePath = makeTestFilePath("BB3_100_drum_break_paprika.wav");
  auto stream = audio::ifstream{filePath.string()};

  // Get the number of frames reported
  const auto reportedFrameNum = stream.info().num_frames();

  // Position the stream at the end
  stream.frame_seekg(0, std::ios_base::end);
  const auto seekedNumFrame = size_t(stream.frame_tellg());

  // Read the data until exhaustion to get the actual data contained in the file
  const auto dataFrameNum = [&]() {

    stream.frame_seekg(0, std::ios_base::beg);
    size_t frameCount{0};

    constexpr std::size_t kNiMediaReadChunkSize = 4096 / sizeof(float);
    const auto samplesPerChunk =
      std::min<std::size_t>(kNiMediaReadChunkSize, reportedFrameNum);
    std::vector<float> data(samplesPerChunk * stream.info().num_channels(), 0.0f);

    while (stream.read((char*)data.data(), std::streamsize(samplesPerChunk)))
    {
      frameCount += stream.frame_gcount();
    }

    return frameCount;
  }();

  std::cout << "Number of frames returning by num_frames " << reportedFrameNum
            << std::endl;
  std::cout << "Number of frames in the file " << dataFrameNum << std::endl;
  std::cout << "Number of frames from seeking " << seekedNumFrame << std::endl;

  CHECK(seekedNumFrame == dataFrameNum);

The output will be

Number of frames returning by num_frames 423360
Number of frames in the file 98090
Number of frames from seeking 423360

our expectation would be that seeking would also return 98090.

Is this the api we're supposed to use ? is there another way ?

Cheers.

PS: Here's the file this test was ran with BB3_100_drum_break_paprika.zip

Switch to a path interface instead of using `std::string` for file paths

On Windows, conversions between std::string and path interfaces results in UTF-8 strings being converted to ANSI, resulting in non-ANSI characters being lost in the conversion process. This results in files not being loaded correctly because they'll fail our valid path checks.

Unable to sample_seekg to the last sample in an AIFF file

Using an AIFF file as input, I am unable to sample_seekg to the last sample in the file. If, however, I read the file sequentially using the extraction operator, I can read all samples in the file (including the last one). I tested this on 7e2de4b.

The following example shows the issue:

    auto in = audio::ifstream{getSamplePath("sample.aif")};
    const auto inputSampleCount =
      static_cast<int>(in.seekg(0, std::ios::end).sample_tellg());

    float value;
    if (in.sample_seekg(inputSampleCount - 1) >> value)
    {
        // this code is never executed
    }

My expectation would have been to be able to sample_seekg to all samples in the file, understanding its argument as an index from zero to inputSampleCount - 1.

Consider the following code, using the same input as above:

    auto in = audio::ifstream{getSamplePath("sample.aif")};
    const auto inputSampleCount =
      static_cast<int>(in.seekg(0, std::ios::end).sample_tellg());

    auto readCount = 0;
    float value;
    in.seekg(0, std::ios::beg);
    while (in >> value)
    {
      ++readCount;
    }

At the end of the execution, readCount == inputSampleCount (as expected).

Furthermore, consider the following example in which each sample is sample_seekg to individually:

    auto in = audio::ifstream{getSamplePath("sample.aif")};
    const auto inputSampleCount =
      static_cast<int>(in.seekg(0, std::ios::end).sample_tellg());

    auto readCount = 0;
    float value;
    in.seekg(0, std::ios::beg);
    while (in.sample_seekg(readCount) >> value)
    {
      ++readCount;
      if (readCount == inputSampleCount)
      {
        break;
      }
    }

At the end of the execution, readCount == inputSampleCount - 1, which is not what I expected (I expected readCount == inputSampleCount).

Am I understanding the API incorrectly here?

Parsing large wav files may end up in infinite loop

See #63.

We've noticed that the bitmask 0xfffffe used to pad chunks while reading wave files could cause the seek position to be corrupted when seeking to positions larger than the bitmask. In the worst case, as encountered by us, this may end up in an infinite loop as the parser would start interpreting random parts of the file as chunk id and size and would move randomly through the file, possibly never leaving the loop.

We think this is a rather critical issue.

Linux does not support mp4 or m4a?

Only wav?

P.S.: I also tried to add all dependencies through conan, that ensures that all libraries are being linked but got same result.

AAC Encoding?

Long time no see :)

Wondering if you gang have looked at supporting encoding, and is it realistic to support encoding AAC? Not sure the state of OS support, but could make bandwidth to work on this topic if its viable

Cheers

MP3 File Reading may Freeze

We seem to have found an issue trying to load the following file. (Zipped so it can be attached) TestMp3.zip

From what I can tell, there seems to be a bug in the code responsible for reading the MP3 file in media_foundation_helper.h L89.

        try
        {
            *read = static_cast<ULONG>( m_source.read( reinterpret_cast<char*>( buffer ), toRead ) );
            return S_OK;
        }

While we're working with template arguments here, m_source in practice is implemented using boost::iostreams::file_descriptor. On windows, this class implements read like this:

    DWORD result;
    if (!::ReadFile(handle_, s, static_cast<DWORD>(n), &result, NULL))
    {
        // report EOF if the write-side of a pipe has been closed
        if (GetLastError() == ERROR_BROKEN_PIPE)
        {
            result = 0;
        }
        else
            throw_system_failure("failed reading");
    }
    return result == 0 ? -1 : static_cast<std::streamsize>(result);

The issue comes from returning -1 in case no bytes were read. SyncronousByteStream::Read casts this to unsigned long and returns 4294967295.

The calling code sadly I can't debug but my assumption would be that it calls Read() until no more bytes are read. Since this cast would cause the number of bytes read to never reach 0, it will continue to read indefinitely or we reach some undefined behaviour.

One solution would be re-interprete -1 (EOF) to 0 (no bytes read), which, from what I can tell, fixes the endless loop and allows ni-media to successfully parse the file.

Why this issue doesn't affect other (most?) mp3 files I don't know. Sadly the documentation on the calling (Windows Media Foundation) code is somewhat limited. :)

Cheers!

Benchmarks

Hey Folks

On first glance this looks really great, so thanks for putting it out there!
I was wondering: have you done any benchmarking on different platforms or against other libraries?
If so publishing any results on the readme or pushing the benchmarks themselves would be amazing.

Cheers!

ALAC support on Windows

Hey,

Hope you are doing well.

I built a script to create Traktor stems called Stemgen. It is based on ni-stem and it creates MP4 audio files using ALAC or AAC. But Traktor can't read ALAC stems on Windows. And it really is a shame to be forced to encode lossy audio files to be able to use stems on Windows.

I haven't been able to test this hypothesis yet but I think that this issue is coming from this library.

More context in the forum and on GitHub.

Can you confirm this hypothesis? Happy to help and send a PR if that's the case :)
