I have noticed that some of media when trying to play via Roku when I click play the sound starts but I get solid bright green screen.

 

When I look in the dashboard it says its playing as "Direct Stream"

 

I have noticed this issue most often with older seasons of Top Gear

The files are .MKV

 

Roku Emby version is 3.0.33

 

Anyone else get this green screen?

It says its update to date:

 

Version 7.6.0  Build 4120

 

Also I watched these same Top Gear episodes with the old Roku Emby client last year and they worked fine.

 

Not sure what would be causing the bright green screen now with this version of the client?

Sounds like maybe the item needs to be transcoded.

 

Can you post the media info from the web app for it please?

@@ebr  Why would the same media play fine in the old Roku App last year but with this new app just display a bright green screen with the audio playing fine?

We don't know, that's why he is asking questions to try and identify it. In addition to what he asked, can you please attach a server ffmpeg log for both the new and old apps? thanks !

I will get the info when I get home, I don't have the old app anymore since you pulled it from the Roku store, there is only the new app now.

@@dcook try the blue neon night app. The old app with a few new tricks. In preferences, set the theme to standard. It will look familar then.

My initial guess is that the old app transcoded it.

So I tried the current roku app, the beta app and the blue neon app and the same green screen in all of them.

I know for a fact that these media played fine last year in the original roku app.  So my guess is that one of the server updates that happened between last year and today are causing the green screen.  Otherwise it would not be happening in all 3 apps on the Roku.

 

The same media plays fine on my Android phone, Android Tablet and via the Web Browser

Server is: Version 3.2.22.0

 

I am not sure what you mean by post the media info?

 

This is all I see when I view an episode in the web app:

I have attached the log for each attempt to watch via Roku

 

I can watch other stuff fine with the Roku app.

roku emby 3.024.txt

roku emby blue neon.txt

roku emby-beta 3.034.txt

There is something in the new roku firmware causing it. This sounds like a roku firmware issue, especially if all 3 apps experience it. To make sure can you try with "force transcoding w/o directstream" in the blue neon app? If this works it will confirm @@ebr's suspicion. It should be transcoding, to work around a new bug introduced in the roku firmware. Do you have a sample of that video handy so I can forward to roku.co forums? Thanks. :)

If I try playing again the same media in BN app and select "force transcode" it works fine.

 

I am running the latest firmware for my Roku

 

@@ebr can you add a "Force Transcode" option either in the new Roku app or in the Emby Server?  

It would be easier if I could just have transcoding turned on all the time, I have 16 cores doing nothing most of the time.

 

@@speechles here is a link to the media:  https://drive.google.com/open?id=0B_PgmDeDsZ_HcUpvdEkxY1A2Snc

 

Its not just that one though I have tried dozens of different episodes

Scroll down on that page and there are specific details about the media (codec, resolution, etc.)

Oh snap it's level -99 because its that god awful Divx 5.0 codec. BLEH.. I had code in the capabilities to detect this, but i forgot to set the isRequired flag to true. Big mistake...

 

 

    mpeg4Conditions.push({
        Condition: "NotEquals"
        Property: "CodecTag"
        Value: "DX50"
        IsRequired: true
    })

 

This is the code required to fix it ebr. This should let the server know mpeg4 with dx50 is a no go.

So is it a Roku firmware issue? or a Emby Roku Client issue?

Its a speechles error that was copied into the new app. I forgot to set isRequired=true for that condition. Thanks for spotting it. Your reward is auto-detect will properly see this now. Thanks again. :)

So is this fixed for all the Roku apps?  Or just the Blue Neon one?

 

That one code change fixes all the roku emby apps for this issue.

 

I will have a new blue neon update very soon.

 

I am sure ebr/luke will have a new beta update too. Roku has to approve the standard emby app, so it will take longer since their eyes have to approve it.

Thx.  This can be tested in the next beta of the official Roku app (3.0.35)

The issue is still happening, Bright green screen with audio. I am using 3.0.41

 

If I use Blue Neon and select Force Transcode it works fine.

 

Any idea when this bug can be fixed?

@@dcook When you force transcode, can you then fast forward a bit? After this press OK on the remote to pop up the OSD. Does it say (copy) for both audio and video and show (directstream)? For "Why?" does it show just container? If so, can you show the media info for the video at hand, and possibly offer a short sample of it. I'd like to have it in the "test" folder with the rest of the problem files Ive ever encountered. Knowing the media info should expose a way to differentiate it as not direct playable.

 

Also, it may just be "something in the water" causing it. Recent roku firmwares have been causing problems, even once solved issues are popping up again. Hello 4GB bug again? Really roku.. for shame. About all I can now offer as wisdom is to make clever use of the force options of blue neon. This is exactly why those options exist. Hopefully these recent issues make the official team adopt force options like blue neon has. The force options have proven themselves useful time and time again. Perhaps, have it hidden behind a setting like "Show advanced playback options" and if enabled, expose ways to force direct and force transcode. I am telling you if users could work around the problem in app they would. It is when they cant they come here.

 

Psst...Hey emby devs, please save yourselves the headaches of rokus firmware mistakes and adopt the playmethod changer. Thanks. :)
