explicit |
Constructor used for factory construction.
| string vrs::AudioContentBlockSpec::asString | ( | ) | const |
Convert to string, to store on disk & reconstruct later using factory constructor.
| bool vrs::AudioContentBlockSpec::isSampleBlockFormatDefined | ( | ) | const |
Tell if the audio sample format is fully defined. For instance, PCM audio data when we have enough details: sample format & channel count.
| void vrs::AudioContentBlockSpec::set | ( | ContentParser & | parser | ) |
when constructing from a string.
