[opus] encoder with FEC+DTX enabled but not detecting noise

[Suresh Thiriveedi]

Hi,

When we pass around 9K samples of only ambient noise (no voice), the
encoder which is enabled FEC+DTX is detecting only some 140 frames as
non-voice (returning only TOC, no frame content). We were expecting all or
more to be identified as non-voice.

Our idea was to check how the decoder re-generates the original ambient
noise during the silence duration (when we feed NULL to decoder) when the
FEC+DTX enabled.


Please clarify.

Thanks
Suresh
