Play MultipleAudioTrack in Roku

Question

I know about Roku doesn't support multiple videos at a time. But, Some Developers are mix up two things multiple playbacks and multiple audio tracks. Roku Does Support Multiple Audio Track?

I tried to Play MultipleAudioTrack in Roku. I used the below code to find a multiple audio track Here ?"m.video.availableAudioTracks :"m.video.availableAudioTracks but here not available any track. my stream check-in VLC MediaPlayer. Here two-track available. But, I not found in Roku. My Audio Format is AAC. I also Set Here m.video.audioFormat = "aac". Any other Configuration required to Playing a multiple Audio.

My m3u8 file is below.

#EXTM3U
#EXT-X-TARGETDURATION:9
#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-VERSION:3
#EXTINF:8,
RokuMedia00000001.ts
#EXTINF:8,
RokuMedia00000002.ts
#EXTINF:8,
RokuMedia00000003.ts

Is there any configuration required for the m3u8 file.

I read the HLS Documentation which is provided by Roku. But, I have still some doubts regarding HLS Stream. I used the Roku Premiere plus device.

For CC, I enable Closed Captions options using coding it's below.

m.videoContent.streamformat = "hls"
m.videoContent.subtitleTracks = [{ language: "EN", description: "EN", trackName: "eia608/1" }]
m.videoContent.subtitleConfig = { trackName: "eia608/1" }

It's not available in M3u8 file content. It's available on my ts File. I mention my M3u8 Content in the above.

Same way, I tried to enable Multiple Audio Track using Coding.

I used Following Field For fetching a multiple Audio Track.

?"m.video.availableAudioTracks :"m.video.availableAudioTracks
m.video.audioFormat = "aac"

I refer to this example of playing a Multiple Audio Track.

I used the aac audio format for playing audio in the Roku video player.

I check the same M3u8 File in other Video Player(VLC, IOS inbuilt player, EXO Player) It takes automatically shows two audio track.

I'm not sure. But, I think Roku Video player Compalsary required multiple Audio tracks in M3u8 File. Like below. Is it Correct?

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="aac",NAME="English",LANGUAGE="en",AUTOSELECT=YES,\
DEFAULT=YES,URI="RokuMedia00000001.ts"

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="aac",NAME="Spanish",LANGUAGE="es-ES",AUTOSELECT=NO,\
DEFAULT=NO,URI="RokuMedia00000001.ts"

But, Here It possible to Put the EXT-X-MEDIA tag in Two Times?

or I don't know which specific field will add I required.

I found one article in the Roku Knowledge Center article Does Roku support multiple audio tracks?

But, I'm not required to enable multiple audio tracks at the same time. or also not required to playing simultaneously. I required to at a time only a single audio track. Because, I know any media player not support multiple audio track and video track the same time.

I required to change the audio track at run time. If my default track in English and using this option, I change to It Spanish or any else.

My Actual question is a how-to enable audio track option which provide by Roku and which fields are required in m3u8 files. To enable these options. or Roku has stopped supporting audiotrack options?

If not mistaken, if Your stream manifest has two audio tracks You should be able to see it in default ROKU menu by pressing * on the remote. I think the option is called available audio tracks or something like that. Anyhow, are You able to see two tracks in that menu? — U.Mitic
Yes I check. but not available. I also check same stream in vlc media player here i found but in roku not available. — Nikunj Chaklasiya
@U.Mitic I refer to this github.com/ctraganos/roku-sdk/blob/master/examples/source/… example. Here I check with my stream but not able to find multiple audio tracks using this example. — Nikunj Chaklasiya

I'm not certain about Audio files, but I know that Rokus don't allow you to buffer more than one Video at a time. This effectively means that a Roku cannot play more than one Video at a time.

The same could be true for audio files but I am not certain.
