.MTS files don't stream to Chromecast (high bit-rate home videos) [solved]

[Guest]

I'm trying out Emby and Plex and today i'm trying to use it to watch home movies which are stored in .MTS container (filmed on a Panasonic camera). I can watch it on the browser and the phone fine, but it won't stream to the Chromecast.

 

Is it doable? Thanks.

HI there, what happens when you try to stream to chromecast?

[Guest]

Hi Luke. It gets the 'thinking dial' for about half a second then the screen just blanks.

Ok, please attach the information requested in how to report a media playback issue. Thanks.

Hiya. Sorry it's taken so long to come back - I actually wiped my testbed and started over, hence the extensive delay.

 

I've tested a couple of other files (i don't actually remember what the original one was now) which are filmed with the same camera - and the same result.

 

I've attached the logs.

 

Thanks.

@@DifficultDerek if you lower the Chromecast quality setting to force a full transcode, does this resolve it?

[Guest]

Sorry, how do i do that? I've googled Chromecast quality settings but the only thing i've found is via the Chrome browser (which i don't use). Is it in Emby? The Transcoding section?

 

I set that to Slow / 21. Didn't work.

 

These videos are short (like a couple of minutes) but the bitrate on this particular one i'm trying right now is 28,087. And ~250mb.

No, it's in the app settings that you're casting from. Click your user icon in the top right -> then playback settings -> then chromecast quality will be under that.

 

Please let us know if this helps. Thanks.

Hi Luke - that worked.

 

I could stream all the way up to 25Mbps but no higher. It might be because my ChromeCast is an older model - it doesn't have 4K capability so it probably is has limited bitrate capability at 1080 too.

 

Thank you.

Thanks for the feedback. I think what needs to happen is we really should automatically transcode these. I think there's some kind of compatibility problem with these videos. The problem is they look like ordinary h264 so it's hard for us to detect that it should be transcoded, so that's why you had to use the quality setting to force the transcoding. We'll look at improving it. Thanks.
