Possible to set user agent? Raspberry pi support

[owenthewizard]

Is it possible to set the user agent? For example to be able to use this to watch Netflix on the Raspberry Pi.

[gort818]

You can, but just curious why would you need to?

[gort818]

You can set the user agent by adding this lines in mainwindow.cpp

//QString UserAgent = "user agent goes here";
//this->webview->page()->profile()->setHttpUserAgent(UserAgent);

i think it should work if you simply run: netflix -user-agent="Mozilla/5.0 (X11; CrOS armv7l 6946.86.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.91 Safari/537.36"

user agent for chromeos (you know that you will need the widevine libs from the chrome recovery image to get it work on arm platforms?)

[owenthewizard]

@omni6 Didn't work, according to this tool; @gort818's method worked.

[gort818]

@owenthewizard I am glad it worked, just curious is there a specific reason you need to set the user agent. If it is really needed I can add a way to change it.

[owenthewizard]

@gort818 Playing Netflix on the Raspberry Pi requires the user agent to be spoofed, as per @omni6's comment.

[gort818]

@owenthewizard Ok did not know that.. I might be able to add something that checks if you are running raspberry pi and and set it to chromeos.. what do you think? would that make it easier?

[owenthewizard]

@gort818 That would be nice, I was going to do that in my fork but you could probably do it better as I don't have experience with Qt.

[gort818]

Ok I will leave this open.. I might have it done today

[gort818]

@owenthewizard ok I just updated it can you give it a go and see if it works?

[owenthewizard]

@gort818 What version of chromium-widevine should I extract widevine from (if it matters)? Alternatively, where can I find a download of 61.0.3163.140? Debian and Arch don't seem to have it anymore.

[gort818]

What distro are you on?

I found this https://github.com/kusti8/chromium-build/releases/download/netflix-1.0.0/chromium-browser_56.0.2924.84-0ubuntu0.14.04.1.1011.deb

Here is it on arch https://archive.archlinux.org/packages/c/chromium/chromium-61.0.3163.100-1-x86_64.pkg.tar.xz but it is for x86

[omni6]

Download for arm? No way afaik. A while ago i commented this https://archlinuxarm.org/forum/viewtopic.php?f=47&t=11600#p56272 but the .deb package dissapeared. You can try something like this: https://forum.vivaldi.net/topic/23226/widevine-and-flash-for-vivaldi-on-arm-spotify-and-tidal-access https://help.vivaldi.com/article/raspberry-pi/

But generally you have to extract this two files out of the chros-recovery into this directory:

/usr/lib/qt/plugins/ppapi/libwidevinecdm.so
 /usr/lib/qt/plugins/ppapi/libwidevinecdmadapter.so

[owenthewizard]

Extracting the widevine libraries from @kusti8's package was a success!

Tested on Arch Linux ARM, Netflix works as expected, however the resolution and framerate are nothing to write home about. I suspect this is because ffmpeg on Arch Linux ARM was not compiled with the the MMAL-accelerated h264 codecs. I will recompile ffmpeg and report back.

[gort818]

O nice! at least we got it going! Did my fix for the Useragent work as intended?

[owenthewizard]

@gort818 Indeed! I saw the user agent change and 1080p unlocker on stdout.

[owenthewizard]

Recompiling ffmpeg didn't make much of a difference that I could tell, maybe the Arch Linux ARM Qt5-webengine package doesn't use system-ffmpeg? Although I think it would as it does in upstream Arch.

[gort818]

I wish I had an extra raspberry pi but there are all busy as headless servers. I wonder if streaming at 1080p it bogging down the cpu.. check your cpu temps when streaming it might be throttling.

[gort818]

@owenthewizard what model pi do you have? Also if you have a time could you do a quick how you got it running on your pi, I would like to add it to the readme for other users.

[omni6]

You're sure that qt5-webengine uses hardware acceleleration (egl)? Had problems to get this work on my odroids but i know that compatiblity is better with raspi. Does it play youtube in hd & fullscreen flawless?

[omni6]

@owenthewizard can you test this?

[owenthewizard]

@gort818 I have a Raspberry Pi 3 Model B. Basically I just cloned and built qtwebflix, then extracted the widevine libraries from @kusti8's chromium build.

@omni6 I don't think it's using hardware acceleration because Netflix was much smoother on my Raspbian card, not to mention being in 1080p. I can use the PKGBUILD you provided but I don't see how it is any different than what I did manually. Netflix worked without registering the plugins, do they need to be registered if they're in /usr/lib/qt/plugins/ppapi/?

I'm planning on doing some more testing this weekend. @gort818 is it possible that hardware acceleration is disabled in qtwebflix? I don't know about the internals of qtwebengine but chromium disables hardware acceleration by default on Linux iirc and needs --ignore-gpu-blacklist to override it.

[omni6]

I can use the PKGBUILD you provided but I don't see how it is any different than what I did manually.

no it is fine if you can do it manually, but if qtwebflix ofiicially support rpi there should be IMO a simple solution to get widevine work.

and needs --ignore-gpu-blacklist to override it.

and --use-gl=egl ?

[gort818]

@owenthewizard this is with --ignore-gpu-blacklist --enable-gpu-rasterization

And with out

Can you give that a try and let me know.

Also try

--enable-native-gpu-memory-buffers

To check the settings add this in the providers file for easy access.

gpu=chrome://gpu

[owenthewizard]

Wow I'm an idiot... Netflix runs perfectly smooth with --ignore-gpu-blacklist... I somehow forgot I needed that...

Anyway, attached are screenshots of chrome://gpu with --ignore-gpu-blacklist, --use-gl=egl, --enable-gpu-rasterization, and --enable-native-gpu-memory-buffers. However I would only recommend using --ignore-gpu-blacklist because enabling the last two cause intermittent issues (e.g. black screen) in Netflix. --use-gl=egl didn't seem to have an effect.

@omni6 The PKGBUILD works as expected, but I think you can drop binutils from the makedepends as it is included in base-devel.

Apologies for the 720p screenshots, I'll be able to test on a 1080p screen tomorrow (at the earliest).

Edit: I think it is safe to say that the Raspberry Pi is now a supported platform.

[gort818]

@owenthewizard awesome glad it is working! @omni6 How would we go about making your PKGBUILD a dependency for arm users?

[omni6]

Basically it is already a dependency for qtwebflix. This pkgbuild provides=('qt5-webengine-widevine') what is a dependency for qtwebflix. x86_64 users have to take widevine from aur, arm users can use the pkgbuild. But you could update the readme.md and provide the link for arm users.

build requires base-devel group to be installed

mkdir qt5-webengine-widevine-rpi && cd qt5-webengine-widevine-rpi
wget https://gist.githubusercontent.com/omni6/e557af6a67a41343aa859816d0113ced/raw/0c4d4f09cdb295ba47e5022adab4813766262f46/PKGBUILD

makepkg -csi

@owenthewizard raspi 3 is aarch64, right? Tested on my 64-bit odroid and this doesn't work but on your raspi everything was fine... i ask because then i should add aarch64 as architecture...

[owenthewizard]

@omni6 Raspberry Pi 3 technically supports aarch64 but upstream only provides support for aarch32. I used a Raspberry Pi 2 Arch Linux ARM tarball to install (armv7). I am planning on testing aarch64 soon (tm), as according to the Gentoo Wiki video hardware acceleration works under aarch64.

[gort818]

@owenthewizard there are some new options you can now set useragent from the commandline.

Usage: qtwebflix [options]
Qtwebflix Help 

 To Control playback rate :
 CTRL + W = speed up 
 CTRL + S = slow down 
 CTRL + R = reset to defualt

Options:
  -h, --help                   Displays this help.
  -v, --version                Displays version information.
  -p, --provider <provider>    Set content provider eg. netflix.com
  -u, --useragent <useragent>  change useragent eg. "Mozilla/5.0 (X11; Linux
                               x86_64; rv:63.0) Gecko/20100101 Firefox/63.0"
