Hi, I would like to direct play a movie to my Chromecast Ultra but i can't....

I can't understand why because here https://github.com/MediaBrowser/Wiki/wiki/Chromecast, it says that MKV is supported by Chromecast, but when I try to play it it says 

"The media is compatible with the device regarding resolution and media type (H.264, AC3, etc.), but is in an incompatible file container (.mkv, .avi, .wmv, etc.). The video will be re-packaged on the fly before streaming it to the device."...

 

Do you know why ?

Hi, this video has AAC 5.1. With AAC audio Chromecast only supports up to 2 channels. They dropped 5.1 support a couple years ago. Does this answer your question?

Can you find a movie with an AC3 audio track that has a bitrate of 384Kb/s and try it?

 

I have AC3 audio track that has a bitrate of 448Kb/s, I can try

What does actually work?

 

This one is Direct Playing, but none of files with AC3, whatever the bitrate, is Direct Playing, only Direct Streaming.

I need to investigate that a bit further.

 

I can't figure out if the problem is from Emby or from the Chromecast.

I tried again others ac3 audio codec video and eac3, ac3 never works and eac3 always work.

i'm trying to think that the problem is from the Chromecast...

No, it's only when it's aac more than 2 channels, or a secondary audio track (non-default).

Well I don't necessarily consider it a problem, that's just what it supports and doesn't support.

 

But yes the Shield can direct play more formats.
