numberOfChannels/sampleRate check in AudioDecoderConfig/AudioEncoderConfig
chrisguttandin opened this issue · comments
Right now a valid AudioEncoderConfig needs to have a numberOfChannels and a sampleRate property greater than zero.

A similar check does not exist to validate an AudioDecoderConfig.

Chrome seems to perform the same non-zero checks for an AudioEncoderConfig and AudioDecoderConfig. But as far as I can tell they are not covered by a WPT.
The checks for an AudioEncoderConfig were added here: #780.
Yeah, we talked about harmonizing implem and tests in an issue not too long ago, but I can't find it.
For decoding, it's not 100% required to provide the sample-rate and the channel count, sometimes it's possible to determine them from the bit stream. Sometimes it is required though.
For encoding, it's always required.
