I have the same problem. Edit: doesn't work in VLC app either.

[aminnez]

@alexmercerind same issue

[amir14a]

I have same problem, mp4 links works on vlc app but doesn't work on dart_vlc, I try dart_vlc example app without any changes and still not work.

[lukaexevio]

@alexmercerind, have you stopped supporting this package?

[fred-derf]

It looks like letsencrypt ssl certificates are broken, but others are working e.g.

https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3

works just fine. Letsencrypt is the most popular CA in the world.

I made a quick attempt to make it work with commandlineArguments: ['--gnutls-dir-trust=$dir'] to a copy of firefox's CA list without luck.

I'm not sure any commandlineArguments are working actually, my test with commandlineArguments: ['--http-user-agent=ArgumentsNotWorking/1.2.3'] fails to change the user agent.

[senatoregiorgio]

Any news about this error? Is there a workaround? I've encountered the same problem. The certificate is valid but the CA is Let's Encrypt.
