crashes from time to time about qtwebflix HOT 20 CLOSED

I haven't had any crashes, can you show me the output?

from qtwebflix.

ehh at the moment qt5-webengine-widevine doesnt work at all. i had to switch in to kde-unstable branch for testing purposes. this webengine version misses the properitary codecs, so no qtwebflix atm. but i think i cant trace that anyhow, nothing qt related crashes...
netflix screen: an error occurred please.... error code ... so far i remember.

i will report when qt 5.10 comes in stable repo.

from qtwebflix.

not much, but here we go:

Ok we might just need an update qt5-webengine-widevine , I will do some tests and find a solution.

from qtwebflix.

Ok I just tested I have zero issues everything is still working, do you have chromium installed?

from qtwebflix.

@omni6 Ok I just installed the latest chromium and qtwebflix does not work, so it seems we have a conflict. I uninstalled it and everything works again.

from qtwebflix.

no thats not the issue i meant.
this is even worse, on what distro are you? On arch we noticed this already, theoretically it could be that qt5-webengine prefers the libwidevinecdmadapter.so from /usr/lib/chromium installed with the chromium package. Link. I dont know how you use/installed the widevine libs. But if one have chromium installed, no addition widevine stuff should be needed because webengine detects the chromium libs.... but this is not confirmed yet.

from qtwebflix.

I tested on Arch and Ubuntu, No crashes on either. Well why not move libwidevinecdmadapter.so to /usr/lib/chromium? This is what QT says

On Linux the Widevine plugin comes with the Google Chrome installation and can be found in “/opt/google/chrome/”, and on some distros such as Arch it also comes as a system package for Chromium and will be under “/usr/lib/chromium/”. The CDM Pepper plugin is named libwidevinecdmadapter.so and depends on libwidevinecdm.so which you can find with it.

Qt Blog wrote:
Qt WebEngine will try to find an already downloaded or installed version of the plugin, but while convinient this might not be enough if you want to ship an application that relies on it being present. In that case you need to extract from Google Chrome and place it in the application or ‘plugins/ppapi’ folder.

that is what we've done, and it worked long time. the problem why not simply use /usr/lib/chromium are conflicts between chromium packages and webengine packages. same files different owners --> conflict.

take a look:
https://bugreports.qt.io/browse/QTBUG-64071

from qtwebflix.

@omni6 Ok I will try something later on, let you know how it goes.

from qtwebflix.

@omni6 I reinstalled chromium and renamed /usr/lib/chromium/libwidevinecdmadapter.so and
libwidevinecdm.so. Netflix will not work in chromium but qtwebflix will work.

That is all I got so far I cannot do anything on my end.

from qtwebflix.

@omni6 I got it!
change the desktop file to
Exec=/usr/bin/netflix --register-pepper-plugins="/usr/lib/qt/plugins/ppapi/libwidevinecdmadapter.so; application/x-ppapi-widevine-cdm"

from qtwebflix.

or we can just set an alias for netflix , also check the aur package you need to make some changes.

Thanks!

from qtwebflix.

all done, works like a charm! Good job :)

from qtwebflix.

Awesome thanks for your patience!

you should consider to announce qtwebflix on e.g https://www.reddit.com/r/kde/ or https://www.reddit.com/r/linux/. i think it has the ability to get much more used, problem is that nobody knows it. There is a lack for packaging in various distros, you really should make it more popular.
