Chrome browser libpepflashplayer.so fails to load

[mwpow3ll]

I downloaded both the master src and the 0.3.6 release src and built (both produce same results), copied the libfreshwrapper-flashplayer.so to ~/.mozilla/plugins, created ~/.config/freshwrapper.conf and set the path to Chrome pepper flash (which by defaults includes the manifest.json with the version), and loaded Firefox. Firefox sees the fresh wrapper flash player plugin, but when I go to http://www.adobe.com/software/flash/about/ I see the error that libpepflashplayer.so failed to load. The path supplied in the conf file is correct and Chrome uses the same flash just fine. chmod 755 doesn't help... any options?

Hi.

Just to be sure, are you using full path to the libpepflashplayer.so, including file name?

Also, try to run ldd -r -d libpepflashplayer.so in a terminal emulator in the directory where libpepflashplayer.so is located. This command tries to load a library and shows what functions (-r) and exported data (-d) are missing. Something like "not found" or "not defined" in its output means there is something wrong with libraries versions.

freshwrapper.conf (essentially example config with the path set, but when I tested the chrome pepper flash instead of the ChromeOS, I used the same path and copied it in)

Were those ldd with -r and -d flags? I've seen something like that with PepperFlash from ChromeOS on an older Linux distribution. ChromeOS had newer libc, and PepperFlash depended on newer symbol versions.

By the way, what distribution are you using? What PepperFlash version? Where did you get it?

Some distributions have SELinux policies enabled by default, which can prevent applications from loading libraries from a user's directories.

Hi, I have just tested out flash from ChromeOS recovery image with freshplayer. I have a few odd observations which may useful here.

Since it is a bit confusing, In the following I will call pepper flash that comes with Chrome browser on Linux (without DRM support) pepper-flash for Linux and the pepper-flash extracted from ChromeOS recovery image ChromeOS flash.

1. in order for Adobe to pick up ChromeOS flash, it seems that first one must have a copy of pepper-flash for Linux installed in the system (say by installing Chrome) AND run Firefox once BEFORE editing freshwrapper.conf to change pepperflash_path to point to ChromeOS flash. Firefox Tools > Addons > Plugins shows flash version to be 26 (version of flash for Linux)

Now close Firefox, edit freshwrapper.conf to change pepperflash_path to point to ChromeOS's libpepflashplayer.so (maybe somewhere in $HOME). Start Firefox, go to Tools > Addons > Plugins. Note that It still shows version 26.

Now go to
http://www.adobe.com/software/flash/about/
and flash is detected and reported as version 25 (version of ChromeOS flash) The message asks you to update flash, just ignore it. Go to
http://drmtest2.adobe.com:8080/SVP/SampleVideoPlayer_FP.html
to do the DRM test, it works. Right click to check flash version, it is reported as 25

2. If the system does not have pepper flash for Linux already installed (more about NPAPI flash later), or if one instalsl freshplayerplugin, then edits freshwrapper.conf and starts Firefox without running it once with pepperflash_path pointing to a copy of pepper-flash for Linux. Firefox > Tools > Addons > Plugins would show flash version to be 0.0.0.0, 1.1.1.1. or some such nonsense. Flash still works for some sites (right click video and flash version is reported as 25 on such sites) but adobe's sites don't pick it up.
   Go to http://www.adobe.com/software/flash/about/ it will tell you to install flash. Likewise the drm test video viewer doesn't open, instead there is a message telling you to get flash.

3. On Ubuntu 16.04, if I compile freshplayer from source, then NPAPI flash must not be installed, otherwise Firefox would just use it, and there is no DRM support.

However, if I install freshplayer from webupd8's ppa, then NPAPI flash (adobe-flashplugin) is installed as dependencies and in that case ChromeOS's flash does load correctly. I suppose the webupd8 maintainer must have changed something.

P.S I tested with a clean Firefox profile to make sure that these are not artifacts due to addons.

Hello and thanks for this wonderful workaround to still use flash.

Instead of flash animations i get a brown yellow placeholder with failed to load error message. Used Version: 3.0.9. Flash works ok in chrome. freshplayer plugin shows in Firefox plugins.
Full path is set in freshwrapper.conf. Also tried putting libpepflashplayer.so in path /usr/lib/pepperflashplugin-nonfree like mentioned in README.MD.

The ldd -r -d for libpepflashplayer.so and libfreshwrapper-player.so gave no errors.

I'm pretty sure it can find libpepflashplayer.so

Has something fundamentally changed in flash, that the wrapper
doesn't work anymore?

Hmm. PepperFlash still works on my machine. I tested only with Flash from Chrome, but haven't tried Flash from ChromeOS yet. Both from Chrome and from ChromeOS, latest available versions.

Have you tried to remove path from freshwrapper.conf? Have you tried the latest freshplayerplugin source? I haven't touched sources for a bit, so forgot what was implemented when. But the latest version seems to be working.

Thanks for your reply.

Without the path it still the same problem. In The default freshwrapper.sh
there is a path, but is commented out.

I use version 3.0.9 downloaded from freshplayerplugin page here on github rigHt now.
Before a fedOra 28 package also freshplayer 3.0.9 with same problem.

Is there a newer one?

Is there a newer one?

There is, from this repository. However I just checked and found no essential changes from 0.3.9 there.

Let's try to figure out which libpepflashplayer.so is loaded. Start Firefox under strace from terminal emulator. You'll need to close Firefox before that, to ensure that whole Firefox runs under strace and not only that part that activates already running copy:

strace -f -e openat,lstat -o log firefox

Navigate to any page with Flash elements, try to load it. You need to see that placeholder message to ensure that FreshPlayerPlugin is started. Then close Firefox. Search for libpepflashplayer in log file:

grep libpepflashplayer log

There should be a list of paths that are tried.
