No audio [Opus]

[TiraelSedai 0]

Hi.

 

I have LG MT49s and one of the video I've downloaded from YT wasn't having sound.

 

Video: VP9

Audio:

OPUS stereo Default
OPUS
stereo
2 ch
48000 Hz
Default: Yes

 

I don't think my TV supports Opus codec.

 

Plex was transcoding both video and audio, which wasn't ideal but it worked.

Hi, is this over Dlna, or are you using our LG app? Thanks !

LG app.

@@SamES didn't we look at opus in the app recently?

I can play this one (VP9/Opus in a webm container) but DirectPlay fails and it falls back to transcoding.  @@Luke, we may need to revisit this combination as it looks like DirectPlay is not correct.  I suspect Opus is a problem.  I remember testing Opus on Roku but I believe I did look at this on LG as well at some stage so not sure why it is a problem now.

Can you provide the full MediaInfo or even a sample file?  Is your file webm?

Sorry, I already deleted the video.

 

Your sample is not playable on any device (including in VLC on PC\Win)

[SamES 1056]

OK, I've previously checked Opus on Roku and Tizen, but not web0s.  

 

@@Luke, for LG, the canPlayType test for 'audio/ogg; codecs="opus"' passes, but my test files with opus audio don't play so I expect it is not really supported.

 

I'll push a change for this.

Great, thanks.

When can I expect update to be live?

[Luke 42077]

As soon as it gets through LG review. Thanks.
