Default Audio Playback Issues

[rangeroob 0]

Hello first off thanks for the your hard work on emby and the roku app. Now to my issue I am having it seems the roku app doesn't like my audio defaults when direct playing on the roku app. I have a number of anime that I put the Japanese as the default language but when played on the roku app it plays the English audio track regardless unless I force it to transcode the file and then it plays the default japanese language. I tried to see if it is the same on other apps including the android and web app but strangely enough they both play the right audio track. If logs are needed let me know.

Which roku app?

 

The roku has 3 flavors of awesome. Was it the official old app, official new beta app, or blue neon night app?

I tested both with beta and official app but have the same issue

Can you please give us specifics on a single instance, including what you have your subtitle handling settings set to under your user playback options?  Thanks.

 

How to Report a Problem

So if I were to play an affected file and made sure that the default language is Japanese when direct playing it does not play the Japanese audio but the English one (which I have set up as the secondary audio). My subtitles are all burnt into the video but the settings are set to English and Default.

 

My Emby Server version is at 3.2.10

 

I set a log through the roku beta app at 5:04 PM EST

 

the file I played was Black_Blood_Brothers_S1E10.m4v

What are the codecs used on the audio stream? These are both AAC and english is the first track? This is because m4v is masqueraded as mp4. Mp4 has this problem with secondary audio tracks. You would have much better luck remux all these into the MKV container if you expect to be able to direct play.

I believe I solved the issue though for me there is going to be a lot of re-ripping involved. I tested with a tool called mkvtoolnix it allows to change the default audio to Japanese and then i can encode to m4v and it plays the right audio and it plays fine on all three platforms. Thanks for all the input

You can do this with just a remux using ffmpeg (-disposition option).  If you like using mkvtoolnix instead and want to convert the resulting file back to an m4v/mp4, you can use ffmpeg for that too very easily, as it's just a container swap.  No re-encoding is needed for either option...just remuxing (stream copying) since you're just altering the info in the container.  I can post sample ffmpeg command lines for either operation if needed.  I keep my videos in mkv containers, personally, which makes in-place header/container editing much easier and it supports more audio options, but I can understand using m4v/mp4 for compatibility reasons.
