Flash error code 3321
Running Ubuntu 16.04 and Firefox 55 i installed freshplayer from webupd8 repository (ppa:nilarimogard/webupd8). I have then downloaded a chrome OS image to get the libpepflashplayer.so with DRM following these instructions https://ubuntuforums.org/showthread.php?t=2363550
libpepflashplayer.so from chrome OS image is 26.0.0.102 and it has DRM. strings -a libpepflashplayer.so | grep PPB_Flash_DRM returns PPB_Flash_DRM;1.1 PPB_Flash_DRM;1.0
When i test DRM at http://drmtest2.adobe.com:8080/SVP/SampleVideoPlayer_FP.html# with the video http://drmtest2.adobe.com:8080/Content/anonymous.f4v i get Flash error code 3321.
A quick Google search tells me it means the individualization step failed. I don't know it it has to do with Freshplayer, with Firefox, with the libpepflashplayer.so file from the Chrome OS image or something else.
Firefox is removing NPAPI support from Firefox, see https://support.mozilla.org/en-US/kb/npapi-plugins. Send all hate to Mozilla for this.
Fails with error code 3321 for me too. There are no new PPAPI calls. It looks like Flash performing some validation internally, but I don't have any idea what kind of. In the web numerous resources mention error 3321, and say that it's related to some URL denying by Chrome browser. I don't have restrictions implemented in the code, since Flash always asked for unrestricted URL access. So that part is mysterious too.
Tested a little bit more, and noticed "i15n" in error message. I though it was i18n, which is shortened "internationalization". But it's "i15n", which is "individualization". As far as I understand it's a process of acquiring decryption key or something similar. It's done via POST request, which somehow fails.
Long story sort, I tried Firefox 52.4.0 esr and drm test page works there.
Something changed in Firefox since 52.0, and I don't know yet, what particularly. More debugging needed.
Should be fixed in 4a29ab58e28e31e0e8a92dfd65e45775e73dcb21, which is now pushed to the master branch.
I would love to try it, but the newest compiled version of freshplayer i can find is 0.3.6, and I have never tried to compile from source code. Is v 0.3.9 around somewhere, or can somebody write a step by step guide to compiling it?
Many thanks in advance
write a step by step guide
There is an instruction on how to build and install the plugin: https://github.com/i-rinat/freshplayerplugin#install. It looks sufficient to me, but since I compile routinely, can't say whenever it's easy to follow.
I finally managed to build the plugin and can confirm that everything works fine. Many thanks for all the help.
For anyone not used to building I can add that what took me a while to figure out was that the cmake command needed the directory of the project like this:
$ sudo cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. freshplayerplugin-0.3.9
