C++ (Cpp) createBusFromInMemoryAudioFile Examples

Example #1

File: AudioBuffer.cpp Project: eocanha/webkit

RefPtr<AudioBuffer> AudioBuffer::createFromAudioFileData(const void* data, size_t dataSize, bool mixToMono, float sampleRate)
{
    RefPtr<AudioBus> bus = createBusFromInMemoryAudioFile(data, dataSize, mixToMono, sampleRate);
    if (!bus)
        return nullptr;
    return adoptRef(*new AudioBuffer(*bus));
}

Example #2

File: AudioBusQt.cpp Project: ZECTBynmo/LabSound

PassOwnPtr<AudioBus> AudioBus::loadPlatformResource(const char* name, float sampleRate)
{
    QString path = QStringLiteral(":/webkit/resources/audio/");
    path.append(QLatin1String(name));
    QResource resource(path);
    return createBusFromInMemoryAudioFile(resource.data(), resource.size(), /* mixToMono */ false, sampleRate);
}

Example #3

File: AudioBuffer.cpp Project: 0omega/platform_external_webkit

PassRefPtr<AudioBuffer> AudioBuffer::createFromAudioFileData(const void* data, size_t dataSize, bool mixToMono, double sampleRate)
{
    OwnPtr<AudioBus> bus = createBusFromInMemoryAudioFile(data, dataSize, mixToMono, sampleRate);
    if (bus.get())
        return adoptRef(new AudioBuffer(bus.get()));

    return 0;
}

Example #4

File: AsyncAudioDecoder.cpp Project: joone/chromium-crosswalk

void AsyncAudioDecoder::decode(DOMArrayBuffer* audioData, float sampleRate, AudioBufferCallback* successCallback, AudioBufferCallback* errorCallback, ScriptPromiseResolver* resolver, AbstractAudioContext* context)
{
    RefPtr<AudioBus> bus = createBusFromInMemoryAudioFile(audioData->data(), audioData->byteLength(), false, sampleRate);

    // Decoding is finished, but we need to do the callbacks on the main thread.
    // The leaked reference to audioBuffer is picked up in notifyComplete.
    Platform::current()->mainThread()->taskRunner()->postTask(BLINK_FROM_HERE, threadSafeBind(&AsyncAudioDecoder::notifyComplete, AllowCrossThreadAccess(audioData), successCallback, errorCallback, bus.release().leakRef(), resolver, context));
}

Example #5

File: AudioBuffer.cpp Project: darktears/blink-crosswalk
