1378077 - Allow audio decoder to output more channels when used with webaudio

Status: RESOLVED DUPLICATE of bug 1378070

(Core :: Web Audio, enhancement, P3)

Description

[Jean-Yves Avenard [:jya]]

This issue was reported to me as being a critical one during the Orpheus audio workshop.

WebAudio shares the same audio decoding architecture as playback.

For playback, as we must make sense of the audio channel ordering, we currently limit the number of audio channels allowed to 8.

In bug 1301518, we added an exception for opus type 255.

When use with WebAudio, we shouldn't restrict the number of channels allowed.

The leaves the question as to what to do with the channel ordering. Do we leave it as what the decoder output (which will vary with some codecs depending on the platform) or do we reorder what we can (up to 8 channels) and leave the remaining one as-is.

Up to the webaudio developer to write work around depending on the platform the code is running.

This was an issue, so I decided to do something about it. This now has been resolved in the spec after a long time bikeshedding: https://github.com/WebAudio/web-audio-api/issues/1089#issuecomment-309810325
