I have just install ubuntu 14.04 on my new PC and have same issue above on firefox 46 but my old one with firefox 46 still work fine even if I uninstall firefox and reinstall it

@mangui Do you have any idea?

[shacharz]

It has to do with FF's mediaSourceExtension: window.MediaSource.isTypeSupported('video/mp4; codecs="avc1.42E01E,mp4a.40.2"'); returns false in FF on ubuntu

I overridden the function, and those are the logs:

window.MediaSource.isTypeSupported = function(){return true;};
function window.MediaSource.isTypeSupported()

[mangui]

is ffmpeg installed ?

[shacharz]

yea, what does it have to do with it?

[mangui]

what is the output of https://www.jwplayer.com/html5/mediasource/ test section ?

is ffmpeg installed ?

Chrome bundles its own H.264 and AAC decoders, whereas Firefox relies on the operating system to provide H.264 and AAC decoders.

The Media Source Extensions are available for:

• WebM: true
• MP4: true
• TS: false

but window.MediaSource.isTypeSupported('video/mp4; codecs="avc1.42E01E,mp4a.40.2"') returns false

[shacharz]

what is the output of https://www.jwplayer.com/html5/mediasource/ test section ?

FYI that page tests nothing, the test section is static. Just for the kicks here's a Firefox 8!!! passing the tests :)*

[shacharz]

So yea, apperently the default Repo for Ubuntu 14.04 comes without the needed codecs (The default 16.04 comes with them btw)

Here's a command to add them: sudo apt-get install ubuntu-restricted-extras

Also, here's a tester that actually works.

@shacharz - the youtube tester will of course still succeed even if media.mediasource.whitelist=true in about:config because youtube is/was whitelisted.

@shacharz @robwalch Do we have any way to catch this error? May be using hls.js api's? I just trying to show error message banner to the user... getting waring message like Media resource blob:[...] could not be decoded.

Hi @joyson-madtha0,

Please file a new issue.

This issue has been closed for over 7 years. Even if your issue is with Firefox on Ubuntu a lot could have changed since then, and we can't help you without a detailed Bug Report describing how to reproduce the error you are experiencing. Be sure to include the version of hls.js you are using, the platform (OS and browser versions), debug logs (very important for errors/escapes), and other items in the Bug Report Template. Thank you!
