Playback of DRM test is failing. #340

Closed Zombie-Ryushu closed 6 years ago

Zombie-Ryushu commented 8 years ago

Playback of Protected content under Flash is failing. I'd like to know if there is a work around required such as installing ChromeOS Flash.

PepperFlash from desktop Chrome doesn't have DRM support, while PepperFlash from ChromeOS does.

If you have libpepflashplayer.so file, you can check for support by calling

strings -a libpepflashplayer.so | grep PPB_Flash_DRM

Version from ChromeOS have output like:

PPB_Flash_DRM;1.1
PPB_Flash_DRM;1.0

while for desktop one there is nothing.

Adobe is now offering Pepper Flash as an independent download from Chromium. Is this Pepper Flash unable to do DRM?

Is this Pepper Flash unable to do DRM?

Unable.

Test is the same, there should be string PPB_Flash_DRM inside a binary. Both i386 and x86-64 versions I tried have no such string inside.

You still can download ChromeOS recovery image directly from Google. It has PepperFlash inside.

This issue was about Flash plugin itself unable to do DRM-related computations. It's required to use version at from ChromeOS, since PepperFlash for desktop Chrome have no DRM-related code compiled in.

Additionally, there is another issue with DRM, #359. Reason is unknown. Probably, something Firefox-related, since drm test page works in Firefox 52 ESR on my machine.
