Then just copy them in some local folder (usually where executable is) and change app paths int main(int argc, char *argv)

Then go and download exactly the same version from official website and extract just the DLLs so you end up with QtWebKit with Chrome 45 trying to use flash from Chrome 54 and failing sporadically - perhaps newer flash version is not backwards compatible with older browser.Ĭheck my previous on how to provide command line parameters to specify flash location (local to your app) but first find out the version of Chrome used by your QtWebEngine and download compatible flash player - e.g. you copied v45 DLLs from browser's directory to system wide location which later on v 54 (or latest) overwrote (lately they repackaged and removed flash from browser so now it installs as a separate package or on first use in system wide location and overwrites your copy) My guess (and it is just a wild guess) is that e.g. That's why it is always a good idea to use local copy and never touch system wide locations. On how to load the Pepper Flash player from a specific location by using command line arguments: -ppapi-flash-path=./libpepflashplayer.so locate and use proper (32/64 bit) libraries in their new location - see.locate and copy proper (32/64 bit) libraries to the expected location.NB! QtWebEngine still uses older version that checks the old location(s) for plugins so even if you have both new packages installed and flash is working in your browser QtWebengine probably still fails to find it in the new location so I guess you are using most recent Chromium web browser that comes packaged without pepper flash yet there must be a separate (system-wide) pepper flash package that should be pulled as dependency (or in case it is only 'recommended' then you must install it yourself - can you verify using you package manager if there is now separate pepper flash package and it is installed) Also during the split probably now system-wide pepper flash has move to a new (system-wide) location so can you verify that file is actually present with ls -la /usr/lib/PepperFlash/libpepflashplayer.so Google recently announced they'll stop packaging their browser and pepper flash plugin together. Is pepper flash running in your Chromium browser?
