Hi! I’m trying to make work a multiple audio stream for hls but doesn’t change the language. The same master.m3u8 works on videojs but not in FV Player. Is made with Bento4 mp4-hls utility.
Here is the master.m3u8 file:#EXTM3U # Created with Bento4 mp4-hls.py version 1.2.0r637 #EXT-X-VERSION:4 # Audio #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="eng",LANGUAGE="eng",AUTOSELECT=YES,DEFAULT=YES,URI="audio/aac/eng/stream.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="hin",LANGUAGE="hin",AUTOSELECT=YES,URI="audio/aac/hin/stream.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="zho",LANGUAGE="zho",AUTOSELECT=YES,URI="audio/aac/zho/stream.m3u8" #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac",NAME="pol",LANGUAGE="pol",AUTOSELECT=YES,URI="audio/aac/pol/stream.m3u8" # Media Playlists #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=595687,BANDWIDTH=622783,CODECS="avc1.4D4028,mp4a.40.2",RESOLUTION=480x272,AUDIO="audio_aac" media-1/stream.m3u8 #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=942864,BANDWIDTH=986312,CODECS="avc1.4D4028,mp4a.40.2",RESOLUTION=640x360,AUDIO="audio_aac" media-2/stream.m3u8 # I-Frame Playlists #EXT-X-I-FRAME-STREAM-INF:AVERAGE-BANDWIDTH=72069,BANDWIDTH=116293,CODECS="avc1.4D4028",RESOLUTION=480x272,URI="media-1/iframes.m3u8" #EXT-X-I-FRAME-STREAM-INF:AVERAGE-BANDWIDTH=128713,BANDWIDTH=208246,CODECS="avc1.4D4028",RESOLUTION=640x360,URI="media-2/iframes.m3u8"

Hello, It’s possible to have some feedback on this issue? I’m testing my stream in some other players such as Theo Player and videojs and is working fine. I can change the audio track. The only one that doesn’t work is FV Player. Can someone give me a clue? I’ll apreciate it.
This is my testing stream:

Thank you very muchBrowser is returning 404 not found errors on aac files and the key pairs are only attached on ts files not aac. Is this the expected behaivour?
Thanks
Hello Gus,
sorry for the late response.
Encrypted HLS streams with multiple audio tracks need to obtain the decryption keys twice. It seems, this is the problem. There was a fix for it rather recently. Please, make sure you are using the beta version, not the release version of FV Player Pro.
Let me know if it helped.
Thanks,
MariaHello Gus,
it doesn’t seem like you are using an encrypted HLS stream actually. The video plays without issue on the HLS.js test page too: https://hls-js.netlify.app/demo/
Thank you for the screenshot, it reveals that FV Player Pro is actually using the Stream Loader to play your stream, but it’s not necessary as obviously the stream doesn’t use URL tokens as it plays on that HLS.js test page. But we will fix that.
My guess is that you have configured the dusqglx8g3hsd.cloudfront.net domain in Settings -> FV Player Pro -> Hosting -> Cloudfront. If you remove it from the configuration there no Stream Loader will be used and the video will play.
Thanks,
MartinHello Martin and Maria, thanks for your answer!
Regarding the encrypted HLS, yesterday I disabled the Cloudfront signed url option in order to let you check my stream. But in a real scenario we need this protection in order to protect from downloads. Is a good practice or you think that another layer of encryption on the hls encoding is needed? With this setup seems to be pretty secure and undownloadable.
I’m gonna check if as says Maria the beta version of the player fixes the multitrack problem.Hello Gus,
yes please, have a look if using the Beta version of FV Player Pro will fix the issue. We did some fixes to the Stream Loader there.
Encrypting the stream is necessary if you really want to protect your videos. That way the video won’t play even if you download the files.
Thanks,
MartinThanks for your help! With the beta version works fine.
Hello Gus,
in that case it’s about time to move this functionality from beta to release. Next time you check the changelog you should be able to see a note of which Beta improvements were moved into Release version. Then you can switch back to Release.
Thanks,
Martin
