Function audioConfigOf

audioConfigOf(
    entry: Uint8Array,
):
    | {
        audioSpecificConfig: Uint8Array;
        channels: number;
        sampleRate: number;
    }
    | undefined
The AAC config and the channel and rate facts of an mp4a sample entry, read from its esds: an ES_Descriptor (tag 0x03) holds the DecoderConfigDescriptor (0x04, 13 bytes of stream facts) which holds the AudioSpecificConfig (0x05). The ES_Descriptor's three optional fields (a stream it depends on, a URL, an OCR stream) come first and are skipped by their flags.
Parameters

    | {
        audioSpecificConfig: Uint8Array;
        channels: number;
