AC3 and Chromecast 2 = direct play instead of transcoding

[Simon_Dec 0]

Hi,

 

I just installed Emby on my server and when I tried to play a MKV file which contains an AC3 audio track on my Chromecast 2 I can see the video track well but I did'nt have any sound. Video is played in "Direct play" mode.

 

I read on Internet that there is some issues with MKV/AC3 combo on a Chromecast, but how can I ask Emby to transcode the audio track.

 

I attach the log file, the path of the video I tried to play is "/files/TV Shows/The Crown/Season 01/The Crown - S01E01 - Wolferton Splash.mkv".

 

Thanks in advance

Set the bitrate limit in the app to something other than auto to force a transcode.

There is no way to only transcode the audio track ?

Hi, just so I understand, the Chromecast has detected that your audio equipement supports ac3, but you're saying that in fact it doesn't and you need to convert the audio?

I'm using a Chromecast 2 which is connected to my TV. Emby decided to direct play the stream to the Chromecast in AC3 and there is no sound on the TV.

 

Edit : I setted the bitrate lower to force transcoding. It's ok for the video track, but ffmpeg only copy the ac3 audio track so my problem is already here.

Anybody ?

Hi, sorry, what model TV do you have? The reason we are direct playing is because we have auto-detected that your TV supports AC-3. You're saying it doesn't so we have to figure out what the best approach to resolve this is. I would like to look into your TV model to see if the auto-detected is wrong or not.

 

Thanks !
