I am new to Linux and I'm trying Ubuntu 20.04.1 on a USB key to see what it's like. I wanted to watch a movie on Prime Video using Firefox, but I couldn't : it asked me to allow DRM, which I did. But still, I wasn't able to watch my movie (says an error occured) and I tried on Netflix (error F7355): issue is the same.
I have been looking on the internet for a solution but I couldn't find any. I have :
- Updated Firefox using
sudo apt install --only-upgrade firefox
- Changed
media.libavcodec.allow-obsolete;false
totrue
in Firefoxabout:config
- Checked that I have OpenH264 and Widevine plugins activated
- Tried commands I found online... Such as
sudo apt-get install libavcodec-extra
,sudo apt-get update && apt-cache search libavcodec-extra
,sudo apt-cache search libav | grep extra-
orsudo apt-cache search libav | grep extra-
...
Most of the posts I found were pretty old. It seems like i'm missing this "libavcodec" but I don't really know what it is nor how I should get it.
I can play YouTube videos, however Twitch videos do not work (Error 4000)
Could anyone help me ? I was happy with my Linux experience so far, but I'm a bit disapointed that it's so hard to do something as simple as watching a stream !
Thanks a lot and sorry for my english, I'm not a native speaker.
