widevine isn't supplied with the chromium deb on linux amd64. you are misinterpreting what the flag does. if bundled is not set, then you hit this case always and widevine is never checked https://source.chromium.org/chromium/chromium/src/+/main:chrome/common/media/cdm_registration.cc;l=207?q=%22Widevine%20enabled%20but%20no%20library%20found%22&ss=chromium you get this error in log (which is what is happening on arm64 rn): `[31833:31833:0216/204151.842227:VERBOSE1:cdm_registration.cc(189)] Widevine enabled but no library found` bundled being set does not actually result in widevine being downloaded from google and supplied along with chromium which is what you are assuming it means.
on linux amd64, windows x86/x64/arm64, macos x64/arm64, and cros arm/arm64/x64 the BUNDLE_WIDEVINE_CDM flag gets set during the build for chromium and chrome https://chromium.googlesource.com/chromium/src/+/HEAD/third_party/widevine/cdm/widevine.gni#23 you could add an `|| target_cpu == "arm64"` under the linux case and get the same result as my patches I assume but I followed piOS and fedora chromium-freeworld's lead with their patches: https://github.com/rpmfusion/chromium-freeworld/blob/d2165a468332661df1439208eb930661caaa9f1e/chromium-enable-widevine.patch#L7-L8 https://github.com/RPi-Distro/chromium-browser/blob/ecaf4660a61064c1c2338131d6a4f0807c424123/debian/patches/widevine-other-locations#L19-L20 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/2008433 Title: Request to enable WidevineCDM checking on ARM64 Status in chromium-browser package in Ubuntu: New Bug description: If possible, could you please include a patch to enable widevinecdm checking on ARM64 linux? currently BUNDLE_WIDEVINE_CDM does not get set for arm64 linux (but does on amd64 linux) so chromium does not even check for widevine even if we have it available and placed in the directory manually.
