问题描述

我知道Roku一次不支持多个视频.但是，某些开发人员将两种内容混合在一起，即多个播放和多个音轨. Roku是否支持多个音轨?

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?

我试图在Roku中播放MultipleAudioTrack.我使用以下代码在此处找到多个音频轨道?"m.video.availableAudioTracks :"m.video.availableAudioTracks，但此处没有任何轨道.我的流签入VLC MediaPlayer.这里有两轨.但是，我在Roku中找不到.我的音频格式是AAC.我也在这里设置m.video.audioFormat = "aac".播放多个音频所需的任何其他配置.

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.

我的m3u8文件在下面.

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

m3u8文件是否需要任何配置.

Is there any configuration required for the m3u8 file.

我阅读了HLS.文档.但是，我对HLS Stream还是有一些疑问.我使用了Roku Premiere plus设备.

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.

对于CC，我使用下面的代码启用隐藏式字幕"选项.

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" }

在M3u8文件内容中不可用.它在我的ts文件中可用.我在上面提到了我的M3u8内容.

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

以同样的方式，我尝试使用编码启用多音轨.

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

我使用跟随字段"来获取多个音轨.

I used Following Field For fetching a multiple Audio Track.

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

我指的是此播放多音轨的示例.

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

我使用aac音频格式在Roku视频播放器中播放音频.

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

我在其他视频播放器(VLC，IOS内置播放器，EXO播放器)中检查了相同的M3u8文件，它会自动显示两个音轨.

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

我不确定.但是，我认为Roku Video Player Compalsary在M3u8文件中需要多个音轨.像下面一样.正确吗?

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"

但是，这里可以将EXT-X-MEDIA标签放两次吗?

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

或者我不知道我要添加哪个特定字段.

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

我在Roku知识中心文章中找到了一篇文章不Roku支援多个音轨

但是，我不需要同时启用多个音轨.或也不需要同时玩.我一次只需要一个音轨.因为，我知道任何媒体播放器都不同时支持多个音频轨道和视频轨道.

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.

我需要在运行时更改音轨.如果我的默认曲目为英语并使用此选项，则将其更改为西班牙语"或其他任何语言.

我的实际问题是Roku提供的如何启用音频轨道选项以及m3u8文件中需要哪些字段.启用这些选项.还是Roku已停止支持音轨选项?

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?
