AudioDecoder: isConfigSupported() static method

config

The dictionary object accepted by AudioDecoder.configure

A Promise that resolves with an object containing the following members:

supported

A boolean value which is true if the given config is supported by the decoder.

config

A copy of the given config with all the fields recognized by the decoder.

TypeError

Thrown if the provided config is invalid; that is, if doesn't have required values (such as an empty codec field) or has invalid values (such as a negative sampleRate).

The following example tests if the browser supports several audio codecs.

const codecs = ["mp4a.40.2", "mp3", "alaw", "ulaw"];
const configs = [];
for (const codec of codecs) {
  configs.push({
    codec,
    sampleRate: 48000,
    numberOfChannels: 1,
    not_supported_field: 123,
  });
}
for (const config of configs) {
  const support = await AudioDecoder.isConfigSupported(config);
  console.log(
    `AudioDecoder's config ${JSON.stringify(support.config)} support: ${
      support.supported
    }`
  );
}
