[MPlayer-users] Issue playing opus audio

[Илья Валеев]

Hello!
I'm trying to play opus audio with mplayer. When I open file, mplayer
return this:

If I try to play file with "-ac fflibopus" like this:

>mplayer file.webm -ac fflibopus

mplayer returns this:

> Playing file.webm.

If I try to play file with "-demuxer lavf" like this:

>mplayer file.webm -demuxer lavf

mplayer returns this:

If I add this to config file:

>audiocodec A_OPUS
>  status working
>  fourcc OPUS
>  driver ffmpeg
>  dll fflibopus

or this:

>audiocodec A_OPUS
>  status working
>  driver ffmpeg
>  dll fflibopus

mplayer only returns lines like this one:

>Option audiocodec needs a parameter at line 4



It does not matter for me how to open file: with libopus or with ffmpeg.
Can you tell me please, how to configure system to play opus encoded files?
