Matching Audio Track Information Ensure that the audio tracks in both your content and ad HLS streams have identical language codes and attributes.
MediaTailor Configuration Verify that your MediaTailor configuration supports multi-language audio tracks and that the ad decision server (ADS) delivers VAST responses with matching audio tracks.
Thanks for your reply.
Here's my content playlist:
#EXTM3U #EXT-X-VERSION:4 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-STREAM-INF:BANDWIDTH=3310624,AVERAGE-BANDWIDTH=1703017,CODECS="avc1.640028,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=25.000,AUDIO="program_audio" contentVideo_1.m3u8 #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="eng",NAME="English",AUTOSELECT=YES,DEFAULT=YES,CHANNELS="2",URI="contentAudio%201.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="deu",NAME="German",AUTOSELECT=YES,DEFAULT=NO,CHANNELS="2",URI="contentAudio%202.m3u8"And here's the Ad playlist:
#EXTM3U #EXT-X-VERSION:4 #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-STREAM-INF:BANDWIDTH=513704,AVERAGE-BANDWIDTH=513704,CODECS="avc1.640028,mp4a.40.2",RESOLUTION=1920x1080,FRAME-RATE=25.000,AUDIO="program_audio" Ad1Video_1.m3u8 #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="eng",NAME="English",AUTOSELECT=YES,DEFAULT=YES,CHANNELS="2",URI="Ad1Audio%201.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="program_audio",LANGUAGE="deu",NAME="German",AUTOSELECT=YES,DEFAULT=NO,CHANNELS="2",URI="Ad1Audio%202.m3u8"In MediaTailor configuration, I'm providing the VAST XML having mediaFile tag which points to Ad content m3u8 playlist as an Ad decision server. What other configuration MediaTailor needs for it to detect the appropriate Language based Ad?@Basel Mohamed
Could you please expand in detail how to achieve this?

In AWS MediaTailor, preserving the audio language track selection during ad playback can be tricky because the player typically treats content and ads as separate streams, which can result in the loss of the selected audio track information when transitioning from content to ad playback and back.
Thanks for your comment. Is there any other way at all to configure this without having client dependency?
I have explored further here. I could see the #EXT-X-CUE-OUT:0, #EXT-X-CUE-IN tags properly on both audio and video playlists. My Ad decision server points to another HLS segment that has the proper audio and video segments. But when mediaTailor stitches, it manipulates and adds only ts segments to both. Still couldn't understand why?
