Chromecast: no sound when casting video with AC3 stream

[ludo15]

Hi,

When I use the android app to cast to my chromecast, I don't have any sound when the video has Ac3 audio.
Pre-transcoding the videos does solve the issue, but I would love a more transparent solution.

Is there a way to solve this issue?

Thanks

Hi,
your chromecast may not support Ac3 audio, to force Mezzmo to always transcode mkv files that have ac3 audio you can edit the profile GoogleChromecast.prf and remove:

<format id="ac3" codec="ac3" encode="1">
</format>

(see this thread for its location: http://forum.conceiva.com/showthread.php/467-FAQ-Where-are-device-profiles-located)

or you can send an email to support [at] conceiva [dot] com and we will send you an updated profile.

Excellent, this did work, I have audio on my video. But when I seek the video using the android app, mezzmo chromecast interface hangs indefinitely.

If the Mezzmo server is transcoding the file on the fly then seeking may not be possible as the section of the file you seek to may not have been transcoded yet. Try pre-transcoding http://www.mezzmo.com/wiki/doku.php?id=pre-transcoding_files&s[]=pre&s[]=transcode your file to allow seeking.

Ok, I guess it couldn't be possible to jump transcoding to where the android app seeks... That would've be quite nice ;)

We are currently working on a feature that will do this using HLS (Apple HTTP Live Streaming), the Chromecast appears to support HLS so we will test here to see if it works and if it does we will include it in the Mezzmo 5.1 update.
