Anything you need from me, let me know. And of course, I'm on windows. But it shouldn't make a difference.

I've checked in some changes to our chromecast receiver. Please restart your casting app and try again. Let me know if there's a difference. Thanks.

Going to try this tonight. What do you mean by “casting app”? I do it via Chrome in browser— so, restart Chrome?

Yes exactly. Thanks.

[Luke 40096]

Or in the case it's the browser so you can just refresh the page.

Still went through transcoding. Server and ffmpeg logs attached.

Still trancoding here too, would you like me to play a specific test file?

I'm wondering if the Chromecast in these TVs updates itself when we restart the tv?

I’m not sure. Something did update recently though. The Dolby Vision icon has changed.

Any updates to address this? I’d reaaaaaally love for this to work. I’ll donate $5!

The problem is that the chromecast api's are saying hevc is not supported. I realize the TV supports, the question is whether or not it's supported through Chromecast.

 

@, as a test, can you try forcing direct play via user permissions? Then try to play a 4k hevc mkv with ac3 audio. Thanks.

[Guest asrequested]

When I get a chance, I'll test that.

Luke, will EAC3 work? I've got a 4k no HDR with EAC3.

How do I force direct play via user permissions?

Don't allow transcoding

It should, but try all of the variations that you have. I'm aware the TV supports them natively. The issue is whether they are allowed via it's built in Chromecast.

OK, first round of quick testing. Tried 3 different movies. One without HDR (Bright), and 2 with HDR. Casting to my display, Bright wouldn't play. I saw the poster/backsplash, the progress bar came up, but playback didn't begin. The other two did play. My display changed to HDR10, also. But I never got audio. One of the movies had an AC3 track. I selected that before playback, the display info said that was what was being used, but no sound was produced. Trying other audio codecs, no audio was produced. Also, while playing, playback would freeze briefly and periodically, then resume. I have a feeling that was due to whatever was happening with the audio??

[Luke 40096]

what's the media info from the web app for each of the three?

[Guest asrequested]

Bright

 

    

 

Justice League

 

 

Blade Runner 2049 (Playback of this one, was a little jerky)

 

[Luke 40096]

We've seen before that level 51 h264 on chromecast won't play, so that one's not surprising.

[Guest asrequested]

I hadn't realized it was H264. So I'm going to convert it to HEVC.

[Guest asrequested]

On further experimentation, 4k HDR with audio was achieved, with these user settings. I had previously disabled conversion without re-encoding. With this, the movie is directly streamed, not directly played.
