Widevine problems in Chrome and Firefox on Ubuntu 19.10

I am having problems streaming some TV sites (ITV Hub, BritBox) on Ubuntu 19.10 in Chrome. This is a recent problem that has only recently started, a few weeks ago there was no problem streaming these sites. I regularly update my system and if is therefore very likely that an update is responsible and I only noticed days or weeks later.

I have started to look at the possibility that Widevine DRM is resonsible after James Shade Ubuntu 19.10 some drm content not streaming noted that-.

The problem is the same in Firefox (72.0.1) and Chrome (79.0.3945.130) (with DRM enabled in both). I note that both ITVPlayer and BritBox are getting an error 400 from a call to as the page loads (this returns with a successful 200 response in Windows). This was all working fine in December

I have looked at the folder /opt/google/chrome/WidevineCdm and found this manifest.json file.I notice that there is no Linux entry under "platforms-OS" surely there should be.

{ "manifest_version": 2, "update_url": "", "name": "WidevineCdm", "description": "Widevine Content Decryption Module", "version": "4.10.1610.0", "minimum_chrome_version": "68.0.3430.0", "x-cdm-module-versions": "4", "x-cdm-interface-versions": "10", "x-cdm-host-versions": "10", "x-cdm-codecs": "vp8,vp09,avc1,av01", "x-cdm-persistent-license-support": false, "x-cdm-supported-encryption-schemes": ["cenc","cbcs"], "icons": { "16": "imgs/icon-128x128.png", "128": "imgs/icon-128x128.png" }, "platforms": [ { "os": "win", "arch": "x86", "sub_package_path": "_platform_specific/win_x86/" }, { "os": "win", "arch": "x64", "sub_package_path": "_platform_specific/win_x64/" }, { "os": "mac", "arch": "x64", "sub_package_path": "_platform_specific/mac_x64/" } ] }

There is a file called "libwidevinecdm.so under /opt/google/chrome/WidevineCdm/_platform_specific/linux_x64 but I cannot read it.

I would really appreciate any help with this.

X86 = Intel (Wintel) Architecture 32 bit X64 = Intel (Wintel) Architecture 64 bit at a guess Mac64 = Apple Intel architecture 64 bit

Unless you have a Sun server, or something IBM your machine will be one of these architectures (there is no hardware specifically designed for Linux (yet).

I don't think this will impact the DRM.

An experiment might be to try running Chrome as sudo (might pipe clean a rights "writer" somewhere).
