no directplay for some 4K video

[barnum 5]

Hi All,

 

On my TCL 4K Android TV (tcl 50c725), Emby transcode some 4K video, I found that in the log :

• "Info App: Profile: VideoCodecProfile, DirectPlay=false. Reason=Android-Exo.Height Condition: LessThanEqual. ConditionValue: 1088. IsRequired: False. "

The same file on my mi box 4 use Directplay.

Can you tell me why Emby doesn't use directplay ?

 

Thanks,

My emby server is 3.6.4

I try several 4K, I have the same problem on all files

Can you please play that item for a few seconds and then follow the instructions to send a log from the app?

 

[barnum 5]

I made some new tests,

With emby client 2.0.09 and 2.O.33 it work

With the last version, it doesn't

[barnum 5]

I generate the log and send them,

The user was "vincent"

[barnum 5]

I see in the beta :

2.0.37

• Fix issues with purchase
• Fix HEVC playback on some device

Maybe that fix doesn't work

[ebr 16169]

Okay, I think there is a bit of a waterfall effect happening in your case.  The initial issue is that the TV doesn't support the audio (DD+) so that requires a remux and then the TVs h264 decoder is reporting it only supports a max height of 1088 so we are transcoding to that resolution.

11-17 16:08:46.799  3702  3702 I System.out: *** Max h264 height: 1088

Seems odd to me that the panel would support different resolutions for the different codecs...  

[ebr 16169]

Do you happen to have any 4K content that is h264?  If so, can you play that and send a log?

[ebr 16169]

Also, if you could provide the ffmpeg log from the previous test.  Thanks.

[barnum 5]

but why it work with the old version of the client ?

Because, previously, we were just assuming the device supported 4K and this caused problems on some devices that don't.  Now we actually ask the system.

[barnum 5]

OK I understand the difference.

But My tv with the old version of the client was able to do directplay for all that files.

And when I put those video on a usbkey, I can play them.

My TV is able to do "Dolby AC4, Dolby TrueHD, Dolby Atmos, ..."

As that's the only way to see where the chain is breaking and what does your TV report as supported. 

[barnum 5]

OK, I'll try to do new test maybe today on on Monday nest week

I'll regenerate all log client and ffmpeg (it's the ffmpeg-transcode file right ?)

Yes please, thanks.

[ebr 16169]

Hi.  Do you know if you have any 4K items in h264 instead of HEVC?  Your TV says it only supports 4K with HEVC and I'd like to try and confirm if that is true or something off in its reporting.

Thanks.

[barnum 5]

I only have HEVC

can you tell me where I can get some test video ?

Convert any of those to AVC? You can do it within Emby itself.

Yep.  Or maybe try this.  To force it to direct play in Emby, temporarily disable transcoding of video permissions for the user in the server.

[barnum 5]

what do you mean by disable video permission ? (my server is under Ubuntu 20.04)

I thought that there was no way to Force directplay ?
