<pre wrap="">I'm having an issue when using osxaudiosink on iOS 12. It looks like iOS 12
sets the AudioChannelLayout.mChannelLayoutTag = 6619138. </pre>

I think this value mean kAudioChannelLayoutTag_Stereo<br>
<br>

<br>
and the channel layout should be something like the "case 2" in the
actual GStreamer code<br>
<br>

<br>
probably a patch to gstosxcoreaudio is needed, the patch should be
not too hard to write, I'll try to fix this bug myself if the
problem still happen after iOS 12 release <br>

<pre wrap="">However, in
gstosxcoreaudio, GStreamer only supports mChannelLayoutTag =
kAudioChannelLayoutTag_UseChannelDescriptions.
if (layout->mChannelLayoutTag !=
kAudioChannelLayoutTag_UseChannelDescriptions) {
GST_ERROR
("Only kAudioChannelLayoutTag_UseChannelDescriptions is
supported.");
*channels = 0;
*channel_mask = 0;
return FALSE;
}
Is this an iOS 12 bug or something GStreamer needs to update.
