Hi,
on ubuntu 20.04 it seems too bright / saturated, frames with squares (eg notebook ones) are shared as points on the edges.
Is there a way to reduce this effect?
Thanks in advance.

Got this error when trying to run the compiled binary. All the dependencies are already installed. Am I missing something here?

When I start the program it crashes after I connected to it with my ios device
Console output:

There isn't even a window that appears when starting it, if that should happen.

If I run uxplay on debug mode, I can see I am missing decoder H.264. I am not sure what to install this decoder, any help is appreciated.

Running Kubuntu 20.04.

Hi,
Thanks for this great project! The build was done very quickly and without a problem.
But unfortunately, I cannot connect via an iPad, problem is that I don't see the server name when I
open screen mirroring from quick actions.
This is what I got from the application execution:

*** WARNING *** Please fix your application to use the native API of Avahi!
*** WARNING *** For more information see <http://0pointer.de/blog/projects/avahi-compat.html>

What could be the issue? I'm using ArchLinux.

I am runningUxPLay in Ubuntu 20.04.1 LTS. When I put the command ./uxplay on a terminal the following messages appear :

Initialized server socket(s)
*** WARNING *** The program 'uxplay' uses the Apple Bonjour compatibility layer of Avahi.

This should be ok. However, if now I open "Screen Mirroring" on my iPad, it doesn't detect the UxPlay server.

I've checked #38 and #2 and I've tried all the solutions in there to try and get a window to pop up, but nothing works.

The iphone sees UxPlay are an option when I click on Airplay but when I click on it, it gives me an error pop up saying that It couldn't connect after about half a minute.

I'm running Ubuntu 21.04
I'm also getting this warning when running uxplay

Runs great, I have found one issue. If I stop mirroring, and quit uxplay in terminal. If I run uxplay again without closing terminal it won't work, it looks like is running fine, but ipad won't connect. I have to complete restart a new terminal session and then launch uxplay, then ipad connects and mirror gui is launched. I was able to duplicate this issue a few times.

I'll see if I can dig in a bit more.

I've been following the development of this and rpiplay.
I don't have much knowledge of gstreamer but I've compiled the project successfully on pi Stretch and ran it with the same parameters as rpiplay. I can connect to it with an iphone and ipad and connection information is shown in the terminal windows.
Unlike rpiplay I am not getting the ios screen output. Can you provide some more information on execution?

I am using Pop OS 20.10. My iPad is successfully being mirrored to my laptop, but the only thing that troubles me a little is the quality. The iPad screen is looking blurry despite using a 5Ghz Wifi network.

Is there something I can do? Is it because of my network?

If you start the mirroring and then close the window, UxPlay keeps running in the background and then you cannot see the iPad screen again unless you kill uxplay process.

I went through the UxPlay source code, but I wasn't able to figure out how it manages its window streaming. I thought this would be just a matter of using a callback and checking a window status, but, well, couldn't do it.

I think a solution would be to stop the whole thing when the window is closed, but I didn't find any callback to trigger when the window is closed... Is it hard to implement?

I successfully compiled the program, got it running and connected my iPhone. However I can't find any info on how to watch the stream. Some additional steps on how to use the program in the README would be useful

Would like to forward the mirror stream to an application which accepts h264 streams only from V4L2 devices.

Perhaps UxPlay -> v4l2loopback via gstreamer ?

Or is gstreamer not necessary as middleman ?

Would appreciate any help and/or insight as to how either of these could be accomplished (setting up the V4L2loopback device and configuring GST to sending the stream to it or sending stream directly to a V4L2loopback device).

Thanks!

As mentioned here https://github.com/FD-/RPiPlay/pull/191, resolution and framerate can be determined with RPiPlay.

Is it possible to add this feature into Uxplay?

Hi, I successfully built the project on Fedora 32 but when I try to use Airplay from the iPad and click on "UxPlay" nothing happens and after a while I get an error saying "Unable to connect to UxPlay". I have tried with a 5ghz wifi network (using my Android phone as a wifi hotspot and my house wifi).

Hi.
I was using uxplay for a while without issues on Manjaro but yesterday I was suddenly unable to connect to the server from my iPad.

The console doesn't show anything appart from the avahi warnings. I tried turning on debugging but still nothing. Tried to restart avahi-daemon, nothing.

The iPad sees the server but when selected it just loads indefinitely and then says it's unable to connect.

There was a recent xorg update on Manjaro, maybe that's the problem?

Thanks

Everything looks fine at the first glance.
The iPad connects to UxPlay.
But there is no video pop-up opening for Ubuntu 20.04.

After awhile:

Any ideas?

So RPiPlay is where active development continues. It compiles for all linux platforms, (+ maybe macos)
You can now run RPiPLay instead of UxPlay on a non-raspberry-pi machine.

-----------------------also----------------------------------------------------------------------------------
In the Pull requests for RPiPlay there is a simple change #196 opened by Waester to use the apple standard ports
(see Pull request "Use static ports" at github FD-/RPiPlay) udp 6000, 6001, 7011; tcp: 7000, 7100
so it works through a firewall with those ports open.

to fix the uxplay code to use these ports:
edit UxPlay/uxplay.cpp line 250: replace "unsigned short port = 0;"
by "unsigned short port = 7000;"

edit UxPlay/lib/raop_ntp.c line 192: replace "unsigned short tport = 0;"
by "unsigned short tport = 7011;"

edit UxPlay/lib/raop_rtp.c line 231: replace "unsigned short cport = 0, dport = 0;"
by "unsigned short cport = 6001, dport = 6000;"

edit UxPlay/lib/raop_rtp_mirror.c line 489: replace "unsigned short dport = 0"
by "unsigned short dport = 7100;"

(i.e., just replace 0 by 7000, 7011, 6001, 6000, and 7100 in these files)

Then open firewall ports 6000, 6001, 7011 as udp, and ports 7000, 7100 as tcp
UxPlay will then work with a firewall running.

The GUI works fine and is visible on my screen but whenever I try to share the UxPlay window on its own without sharing my entire screen, it doesn't appear on the options.

When I run $./uxplay, nothing shows up. If I run $GST_DEBUG=3 ./uxplay, I get the following message. Any suggestions?

Works perfectly on fedora 32
but on arch the program runs but nothing shows up on iOS when hitting Screen Mirroring.

I am using a 5GHz connection (intel 6235 wifi)

Also is there a way to print logs? Thank you

I might look really stupid, but how do I start the server? Which command do I have to type in?

Thanks a lot!

Ok now I know that you can start it with ./uxplay

But then I get a warning message:

Hi. I wasn't able to complete the installation because I get the following error in the make step.

I can see and select UxPlay on the iPad (same wifi network), but no window is showing and I get no further debug information about a connection on the console.

Any idea how to fix this? Does the firewall block something?

the audio works but there is not any video on Ubuntu 20.04.

I have a fresh KDE Neon installation, after having built UxPlay without errors, i get

Unable to connect

Unable to connect and iPad can't find it

Info

• Laptop: Arch Linux x86_64
• iPad: iPadOS 14.4.2

I tried the ways below, but it still didn't work:

1. Turn off the firewall
2. Make sure my iPad and laptop connected to the same 5GHz WiFi
3. Try using the self compiled version and the version in the Arch User Repository
4. No proxy used

The only hint I get is output from Konsole but I don't know how to fix it.

I would be very grateful if the developer could provide a solution.

Thanks!

macos is unix env

I tried to see whether I could make UxPlay run with Ubuntu 16.04. I upgraded openSSL to version 1.1.1h and then edited the file link.txt in the CMakefiles/uxplay.dir directory to point to the correct version of librcypt.so on my computer. Running make then ran without errors.

After starting uxplay and trying to connect an iPad, I immediately got a segmentation fault (The iPad saw the uXplay server and the uXplay server established the connection).

So I guess there are other dependencies that are not compatible with ubuntu 16.04. If these are simple manual upgrade issues, I can try to to this. It is not terribly urgent though, since at some point I will be upgrading to 18.04.

Any suggestions are welcome. Thanks in advance.

I'm eager to install UxPlay on all the Linux systems at home. Right now, the airplay name shows up as 'UxPlay'. I'd like to have multiple computers running UxPlay and have a way to set the name that shows up (other than editing the source and recompiling :) - I believe that simply adopting the hostname for the UxPlay name would be a good solution.

I was able to compile uxplay with no issue; after disabling the firewall, I seem to be able to connect (from ipad pro), but no window with the mirrored screen is appearing. The ipad seems to think it is mirrored to uxplay. There are connection closed messages when clicking "stop mirroring" on the ipad.

This is on ubuntu:

As the title says, when one iPad connect streaming works fine. When a second iPad connects the first one isn't kicked from the connection, but the video streams somehow merge and give some very weird results. See image. When moving content on either iPad the image on the computer reflects this but elements of both iPad's screens are displayed.

To reproduce:

1. Start uxplay
2. Connect an iPad to screen mirroring
3. Connect a second iPad to screen mirroring
4. Mayhem

I don't know if the same issue appears with other iDevices but I imagine it does

Hello,
I have a problem connecting my Ipad using UxPlay. I am running ubuntu 20.0.4 Focal. I fire uxplay using ./uxplay. When I click on my Ipad the button to mirror screen I can see uxplay has been discovered, but when I click on it nothing happen. I can the the wheel on my iPad running but nothing show up on my screen. I have tested various solutions, including changing the video sink etc... but it seems that the iPad can not connect. I have even disabled secure boot.
Does anyone has a solution ?

I am currently running Kubuntu 20.04 LTS on AMD Ryzen 7 2700X / NVIDIA GeForce 1060 3GB, when I try to connect to uxplay, it crashes immediately with these outputs:

This software is very useful. However, due to the bandwidth it requires, it would be extremely useful if sharing could also be done via USB cable. Are there any prospects for making this work?

Hi, I am trying to run this after building from source, and I have heard several people say that I need to remove the gstreamer1.0-vaapi package for Intel Graphics (I am using an Nvidia graphics card). However, gstreamer1.0-vaapi seems to be a requirement for the pop-desktop component. Is there a workaround for this so that I can run UxPlay without removing gstreamer1.0-vaapi?

After running ./uxplay and mirroring, here is the output that I get.

Hi,

Would anyone have any advice how to run ExPlay in full screen rather than in a window, similarly to RPiPlay?

Thx

Thanks for making this. I'm having a problem with the build, in that it can't find a header file. After 'make' I get:

One common fix for this is to install a libavahi-compat-libdnssd-dev, but in my case it's already installed:

Hi, I tried this app and it works great for a single device. However, when I try to stream from 2 apple devices in parallel, seems like streams just overlap each other within the same window. Noticed the same issue on RPiPlay as well. Is there any way to run multiple streams?

OS: Ubuntu 20.04
Apple devices: iPhone and iPad

Hi, this project is a great tool and it works really well.
Yet, it only works with a workaround on my company / a public network.
I need my smartphone to generate a hotspot onto which I connect with the iPad and the Linux PC
What could be the reason that it does not work for the public WLAN out of the box?
Is there something I can do to make it work?

It's just the 1% missing to make it perfect, sorry ;-)
Best regards,
Lukas

Hello :)
Since the Airplay-showing window has no Title it is impossible to share this window within a BigBlueButton-session (probably other video-conferencing-tools, too)
I'm afraid that I don't understand the sourcecode deep enough to figure out where the window is created to set an apropriate name.

It would be GREAT if you could add this.
sincerely,
Jesko

Thanks for this cool project!

Unfortunately I only see garbage in the stream from my iPhone 7 (iOS 13.6). Running on a ThinkPad W540 with a Nvida.
First I had no pic at all, then I followed the help in #2 and changed the videosink.

Any ideas?

Hi,

I could install UxPlay without issues. After running uxplay I can find it with my iPad, but when I try to connect I get a Segmentation fault error.
Here is the full screen log:

Initialized server socket(s)
*** WARNING *** The program 'uxplay' uses the Apple Bonjour compatibility layer of Avahi.
*** WARNING *** Please fix your application to use the native API of Avahi!

Segmentation fault (core dumped)

I'm using Ubuntu 20.10 and a Intel graphics card (UHD Graphics 620 (Whiskey Lake))

Any idea how to fix it?

UxPlay starts, but a window do not show up.

Prompt shows:

libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0

It looks like they devices connected successfully, but I get no window on the laptop that shows the ipad screen.
