Opus/Ogg pre_skip issue

[Lee Matthews]

Hi

I'm grabbing audio from a mic to save to a file using the following pipeline :

autoaudiosrc ! audioconvert ! opusenc ! oggmux ! filesink

The recorded file plays fine under vlc and firefox, but chrome does not seem to like it.

It appears that there is an issue to do with "minimum codec delay" or pre_skip, chrome requires a minimum of 80ms.

I've tried looking at oggmux and opusenc using gst-inspect-1.0, but I cannot find any reference to pre_skip.

Does anyone know what the default pre_skip value is and how I may change it ?

Thanks
Lee
