gnome-network-displays's Introduction

WARNING

This project has been moved to https://gitlab.gnome.org/GNOME/gnome-network-displays

All issues have also been moved there.

This is an experimental implementation of Wi-Fi Display (aka Miracast).

The application will stream the selected monitor if the mutter screencast portal is available. If it is unavailable, a fallback to X11 based frame grabbing will happen. As such, it should work fine in almost all setups.

To get audio streaming, you need to change the audio output in pulseaudio to use the created "Network-Displays" sink.

To use it, you will need:

openh264 or x264
For audio supporting using AAC one of fdkaacenc, faac or avenc_aac
NetworkManager version > 1.15.2

Build

To build it locally:

clone the repository
install meson
run meson build on the cloned repository
run meson install on the build folder created by meson

Devices

The following devices have been tested:

Measy "Miracast Receiver" Model A2W
- Announces itself as EZMirror/EZCast
- Only supports uncompressed audio (LPCM) which is not supported yet
LG WebOS TV
MontoView (Software Revision 2.18.02)
MiraScreen

Testing

For testing purposes you can run with NETWORK_DISPLAYS_DUMMY=1 set. In that case, a dummy sink will be provided that allows connecting on localhost using any RTSP capable client to test WFD streaming.

You can connect to rtsp://localhost:7236/wfd1.0 then.

Debugging

Codecs

Appropriate video/audio encoders will be selected automatically. You should also get a notification if codecs are missing and an offer to automatically install these. To debug the codecs themselves, you can modify the default choice by setting the NETWORK_DISPLAYS_H264_ENC and NETWORK_DISPLAYS_AAC_ENC environment variables and specifying the gstreamer element to use (if supported and detected). Run with G_MESSAGES_DEBUG=all to see the selection at work during connection establishment.

Connection issues

P2P WiFi/WiFi Direct and the mechanism to establish a connection is a relatively complicated process that can fail in a number of different ways and stages.

As a first step, you should run with G_MESSAGES_DEBUG=all to get a better idea when the failure happens. Your TV/Display may also give an indication about the progress. Much of the information is also displayed in the UI, but might only be visible for a very short period of time.

Discovery

The first required step is successful discovery of the remote device. This step can already be problematic sometimes. Confirm the following, each ensuring that support exists:

Run gnome-network-displays with G_MESSAGES_DEBUG=all. This will print a lot more information. Theoretically it may be that we see the device, but think that it is not WiFi Display capable (e.g. because the wpa_supplicant support is missing, see further below). Look out for the following messages:
- WFDP2PRegistry: Got NMClient: The connection to NetworkManager works.
- WFDP2PRegistry: Found a new device, creating provider: This means that we have a seemingly usable P2P device installed.
- WFDP2PProvider: Ignoring peer "XX:XX:XX:XX:XX" (Y) as it has no WFDIEs set: This means there is a P2P device, but it does not seem to support WiFi Display. It may also mean that wpa_supplicant is not complied with the required support, see below.
- WFDP2PProvider: Found a new sink with peer X on device Y: The device has been found, everything should be good.
nmcli device shows your WiFi device and a corresponding p2p-dev-X device. If you do not see your WiFi device, then NetworkManager is probably not managing it for some reason. Both the main WiFi device and the P2P device need to be managed by NetworkManager.
iw dev should show an Unnamed/non-netdev interface device with type P2P-device.

If this is not the case, then the device is likely unsupported. One example of this are legacy wext drivers, which may support P2P operation, but are not (and will not be) supported by this software.
NetworkManager only support P2P operation together with wpa_supplicant. The use of iwd is currently not supported and you may have enabled it in NetworkManager.
If NetworkManager does not even show a device, then, as root, run
```
gdbus call --system --dest fi.w1.wpa_supplicant1 --object-path /fi/w1/wpa_supplicant1 --method org.freedesktop.DBus.Properties.Get fi.w1.wpa_supplicant1 Capabilities
```
This should output something like (<['ap', 'ibss-rsn', 'p2p', 'pmf', 'mesh', 'ft', 'sha384']>,). Make sure that p2p is listed here. If it is not, then wpa_supplicant was compiled without P2P WiFi support (CONFIG_P2P).
If a device is shown, but it does not work, then, as root, run
```
gdbus call --system --dest fi.w1.wpa_supplicant1 --object-path /fi/w1/wpa_supplicant1 --method org.freedesktop.DBus.Properties.Get fi.w1.wpa_supplicant1 WFDIEs
```
If this runs successfully, it'll return (<@ay []>,). This answer will be longer when we try to connect to a device, but only at that point. If it shows an error, then your wpa_supplicant was compiled without WiFi Display support (CONFIG_WIFI_DISPLAY).

If everything looks good, but you still can't find the TV, then please try the following:

Search for it using another device at the same time.

Try running

gdbus call --system --dest fi.w1.wpa_supplicant1 --object-path /fi/w1/wpa_supplicant1 --method org.freedesktop.DBus.Properties.Set fi.w1.wpa_supplicant1 WFDIEs "<@ay [0x00, 0x00, 0x06, 0x00, 0x90, 0x1c, 0x44, 0x00, 0xc8]>"

Doing this will set the WFD Information Elements earlier in the process. It should not make a difference. But if it does, then some bigger changes will be needed.

If you can, try to get a capture of another device discovering it.
```
iw phy phyX interface add mon0 type monitor
ip link set mon0 up
```
Then connect to it using wireshark. You may need to disable your normal WiFi connection and change the channel using iw dev. Explaining the details is out of scope for this document.

Establishing a P2P Group

When you click on the TV, the first step is to establish a WiFi P2P connection. Check whether you see the message:

Got state change notification from streaming sink to state ND_SINK_STATE_WAIT_P2P
[...]
Got state change notification from streaming sink to state ND_SINK_STATE_WAIT_SOCKET

If you see both of these messages, then we have successfully created a P2P Group.

Network configuration and socket connection

What happens next is that both side will configure their network. Then the TV will establish a connection to gnome-network-displays.

Things could go wrong here:

Usually, NetworkManager will set up the network to be shared using dnsmasq
A local firewall might block DHCP requests/responses or prevent the later connection

At this point the IP link is there. You can do the following:

Look into the NetworkManager log whether you see something obviously wrong (unlikely, as otherwise it should disconnect immediately).
The low level link is established (i.e. a P2P network device has been created). This means, to debug further, we can montior this network device and see what is happening. We should see a DHCP handshake to configure the network, and then an attempt to establish an RTSP connection.

The easiest way to do this is to have wireshark running. Then, right after clicking on the TV, the P2P device will show up in the list. Quickly start a capture on it.

Alternatively, use a script like the following (as root):
```
interface=""; while [ -z "$interface" ]; do interface=$( ls /sys/class/net/ | grep -- p2p- ); sleep 0.1; done; echo $interface; tcpdump -i "$interface" -w /tmp/p2p-connection-dump.pcap
```
And then open the created dump file /tmp/p2p-connection-dump.pcap in Wireshark.

RTSP stream issues

Not all devices are compliant, and the standard is a bit odd. If you have problems where the stream seems to start, but then does not work or stop after a while.

Try the following:

Run with G_MESSAGES_DEBUG=all and check if you see something that is wrong. Note that certain warnings are expected.
Try grabbing a tcpdump/wireshark capture (see above) and check whether you see something weird in the RTSP stream.
It could also be an issue with the GStreamer pipeline not starting properly. This can possibly be debugged using e.g. GST_DEBUG=*:5, but is generally harder to pin point. Try it a few times, and check if the problem persists.

Microsoft Wireless Adapter v2 not working

Hi, I'm trying to connect to my Microsoft Wireless Adapter v2 (Miracast and WiDi compatible, firmware 2.0.8381) with gnome-network-displays, didn't succeed so far

firewall is off when experimenting

I got the ND_SINK_STATE_ERROR

It would be really great to make it work since this dongle is widely used, I'd gladly help for further debugging

Working like a charm on Windows 10

Using actually up to date manjaro liniux

Dyon Screencast

Hi,

this is my try https://github.com/ArnoldSchiller/dyontvcast/blob/master/screencast.txt
This is my attempt with this software. But I have no idea why it doesn't work. So far I come to a short black screen on the Dyon Smart TV and then that's it. Maybe a wfd ies entry would help me, but I have no idea what to put there.

Any Ideas?
Thank you and many greetings

Can't see Hisense SmartTV

I run app with :
G_MESSAGES_DEBUG=all gnome-screencast

And show this: https://pastebin.com/gMZ2scqp
And it doesn't show any video Sink in the GUI. What can i do?
Thanks.

How to check mutter screencast portal is avaliable?

The application will stream the selected monitor if the mutter screencast
portal is available. If it is unavailable, a fallback to X11 based frame
grabbing will happen. As such, it should work fine in almost all setups.

I checked https://jgrulich.cz/2018/07/04/how-to-enable-and-use-screen-sharing-on-wayland/ and https://wiki.gnome.org/Projects/Mutter/RemoteDesktop and not sure how to check if any of that options (screencast portal, xdg-desktop -portal) is avaliable

Any command to check if I have everything setup correctly? I'm on arch linux and wayland

$ echo $XDG_SESSION_TYPE

installation mint 19.2 (ubuntu 18.04)

sorry, i'm a bit of a noob. i can't see anywhere in the readme how to install it on linux mint 19.2 (ubuntu 18.04). can anyone please guide me through the installation for ubuntu?

thanks in advance

gnome-screencast does not see all WiFi Display devices.

Trying out screencast on our X11 laptops we can see neighbouring WiFi display devices
but our own projectors (Epson) does not show up.
Is Epson different? Maybe something we have forgotten ?

feature request: dev package

I understand the project is still mainly in development but any chance we could get a nightly dev .deb or something along those lines? Could help get more to test if nothing else.

Cant connect to anycast dongle (miracast)

After showing this:

Establishing connection to sin ... then Error

how to find error log?

How can we try this out? no Install guide

How complete is this? are their instruction on how to try this out.?

Fails with Smart TV LG WEBOS

Hi !
It's not possible for me to connect my Ubuntu Laptop with WebOS (TV LG).
It's function on Windows but not on Ubuntu.

Error in Ubuntu 19.04

Today they updated network-manager to 1.16 in the daily build of Ubuntu disco, so we finally can try this in Ubuntu, I did so, installed the dependencies run meson and ninja, everything fine, then I run gnome-screencast but I got an error 'Screencast portal is not available' between other warnings, I'll attach screenshot.

flatpak yml or json manifest support

First of all thank you for developing this tool.
I am on Ubuntu 16.04 platform and some dependencies to build gnome-screencast fails.
Flatpak provides latest SDK libraries to build and run it in my platform.
Would anybody help me prepare .json or .yml manifest to build it?

No feedback when WiFi is disabled

The user should be prompted to enable WiFi to use Miracast.

gnome-screencast howto?

I tried gnome-screencast under X11/MATE and I cannot see anything to cast to.
We have projectors here which Windows can cast too but I don't see any of them in
gnome-screencast.

Am I missing something?
I use Gentoo with a custom kernel, is there something I need to add?

LG webOS failure to connect

Hi, sorry to dig this one up again but it looks like I am having a very similar error like #41 although stopping firewalld did not help.
I am also on fedora 30 with your COPR and on LG webOS.

The TV is found as a sink.
The TV says "[no name] connecting".
Then the TV says detecting Miracast signal.
Then the Connection fails.

Does not give feedback when connection was cancelled by sink

When I try to connect gnome-screencast to my Sharp TV, after one or two seconds of "Connecting..." my TV returns to display a "Ready for connection" message, as if the connection was refused. However, GNOME Screencast continues to display the "Establishing connection" dialog as if the connection was not refused.

My hypothesis is that the connection was refused, as GNOME Screencast continues showing that message indefinitely. I am on Fedora 29 Wayland

Cannot connect to any sink (real or dummy)

When I run:

I get a window with the dummy wfd sink, and after some time, it also finds my Samsung Smart TV:

...and immediately the window gets closed;

When I select my Samsung TV, it stays hanging on "connecting" too.
When I use Windows 8.1 I can perfectly mirror the laptop's screen to the Samsung TV (it gets installed as a "projector"), so it cannot be a hardware problem.

When I use this software I actually get a connect, the Samsung TV shows a window where it wants permission for the laptop to connect.

The gnome-screencast software seems to be falling back to its X11 mode, but I understand that is expected behaviour.

I am running on Ubuntu 19.04 ; recompiling wpa_supplicant with version 2.8 (which has default P2P enabled) didn't make any difference.

What am I doing wrong?

EDIT: I am a newby on meson, so I just built it by going into the directory where README.md resides, do meson builddir, cd builddir, ninja. Hope that was alright, couldn't find any pointers in the doc...

EDIT: Added multiple quotations so that it is not inline code but multi-line.

WiFi Direct instead of WiFi P2P

I see in GNOME Network Display the message "No Wi-Fi P2P adapters found" and when I look up Wi-Fi P2P I see it was initially called that, but they settled on Wi-Fi Direct.
https://en.wikipedia.org/wiki/Wi-Fi_Direct

And also found a typo on the copr page:
https://copr.fedorainfracloud.org/coprs/benzea/screencast/

dnf install gnome-newtork-displays

dnf install gnome-network-displays

Is the patch needed? Why you did not create a pull request to the gst-rtsp-server repository like you did with NetworkManager?

Segmentation Fault

I can't connect to my LG Smart TV because gnome-network-displays crashes with a segmentation fault error.
The output from ´G_MESSAGES_DEBUG=all gnome-network-displays --display=$DISPLAY´ is the one below. I'm running updated Arch and I have already installed openh264 but didn't solve it.

trying to connect to Roku 4

Fedora 30 using the copr package at https://copr.fedorainfracloud.org/coprs/benzea/screencast/

Roku 4 comes up in the network displays, no prompt on the TV, I've stopped firewalld entirely, no iptables rules and made sure selinux=permissive, here's journalctl output, hope this gives a clue thanks for this great package!

F30 broken dependencies

I do not know where to report your copr repo issue. I am a newbie, please be patient with me.

Dependecies not met on F30 when installing from copr benzea/screencast:

nothing provides gstreamer1-plugin-openh264 needed by gnome-screencast-0.1.0-0.20190306git887b4da3.fc30.x86_64

Thank you in advance

Debian gstreamer-rtsp-server

Hi, I am excited to use this app, however, I have a problem when building the app. I end up with the following message:

Dependency gstreamer-rtsp-server-1.0 found: NO (tried pkgconfig and cmake)

src/wfd/meson.build:20:0: ERROR:  Dependency "gstreamer-rtsp-server-1.0" not found, tried pkgconfig and cmake

I am using Debian 10, and I have tried to install several packages which may related to it as follow:
-gstreamer1.0-rtsp
-gir1.2-gst-rtsp-server

Both not solve my problem. Could you please kindly give me a suggestion to have a successful build. Thank you in advance.

Better Category in desktop files

Categories=GTK seem inappropriate, how about
Categories=AudioVideo instead?

Implement WFD IE setting for the source interface

As was found out by @cunidev in issue #4, we need to set the WFD IEs correctly for some sinks to work. At least a few sinks work fine without doing so, but in these elements e.g. the port to connect to is set.

This will need changes on the network manager side. For anyone affected by this, you can run the following command (as root) before starting gnome-screencast to work around this issue:

gdbus call --system --dest fi.w1.wpa_supplicant1 --object-path /fi/w1/wpa_supplicant1 --method org.freedesktop.DBus.Properties.Set fi.w1.wpa_supplicant1 WFDIEs "<@ay [0x00, 0x00, 0x06, 0x00, 0x90, 0x1c, 0x44, 0x00, 0xc8]>"

Codecs are installed but: WfdMediaFactory: Error creating encoding pipeline.

wfd-encoder-bin.log

For the life of me, I do not know what I am doing wrong here.
Logged on in Debian Testing (With Experimental NetworkManager), X11 or Wayland, same result.
gnome-screencast cloned from gitlab and compiled successfully.
Codecs check out, I think. Can anyone deduce the cause of the following output?

How to build the package?

How to build the package on debian? I'm new to meson build system. this repo lacks of installation instruction which makes me a bit struggle to build. By reading out quick start on meson, I run:

$ cd gnome-network-displays-0.90.0
$ mkdir builddir
$ meson builddir

But it seems it has many dependencies problems. and some package not available on apt package management system. Should I install the dependencies one by one what stated on error log of meson build, or does it have other easier method to install and solving all dependencies?

Thanks

Miracast removed in Android 8.0 (Oreo)

Hello

My Philips TV 65PUS6412/12, 65" LED-TV tells me when i run The Airpay Android App and want to enable Miracast in the Settings, that Miracast-Functionality was removed since in Android 8.0 (Oreo). So is there an alternative like Chrmecast Protocol?

With kind regards
Marc

Should I try on top of merge commit? Which seems to be https://gitlab.freedesktop.org/NetworkManager/NetworkManager/commit/ce3f7bf812c21773251748693cd39d2fb54b9055

Can't see my Sony TV which is Miracast enabled

I have installed "gnome-screencast" from your COPR repo

Streaming shows black screen after installing audio drivers

Worked (somewhat) properly before, but after installing gstreamer "bad-nonfree" plugins from RPMfusion (for audio support) I get only a black screen with those warnings:

(gnome-screencast:3663): GLib-GObject-WARNING **: 16:22:53.447: g_object_set_is_valid_property: object class 'GstX264Enc' has no property named 'max-rc-lookahead'
Warning from pulseaudio-source: Impossibile registrare l'audio a velocità adeguata

Translated: "Can't record audio at appropriate speed"

Configure connection for local routing only

If the remote peer becomes group owner, then we end up trying to use the connection to connect to the internet. That is pretty stupid, we need to only use the connection for the local network.

(I have private a trace where this happened.)

Typo in copr instructions

"dnf install gnome-newtwork-displays" has a little bit too much 'w' in it ;)

It should read:

dnf install gnome-network-displays

Ninja test failure - appstream ?

Can you tell me how to overcome this ninja test issue?

New name?

The current name is a bit confusing, as "screencast" is most commonly used for video recordings of the screen (analog to "screenshot").

Some clearer, but still generic alternatives (from the IRC discussion last week) if we intend this to be an "official" GNOME app:

Network Displays
Remote Displays
Wifi Displays

On the other hand, if this is intended to be a third-party app we could brainstorm some less generic names.

packets drop even with the dummy sink

Unable to stream even to the dummy display.
After running gnome-network-displays with NETWORK_DISPLAYS_DUMMY=1 and G_MESSAGES_DEBUG=all, I get the following log after selecting the dummy display and connecting to the rtsp server using vlc.

I've 'x264' installed, why would screencast possibly tell me it won't find an encoder? Tried on a laptop using both the intel GPU and AMD GPU with the same result.

Gnome-screencast crash

After connecting to the tv the application crash with the following messages:

** (gnome-screencast:3347): WARNING **: 10:11:11.347: WfdClient: No resolution found, falling back to standard FullHD resolution.

Chromecast support

It would be nice to support other devices and not only Miracast (revision 1).

One such device that a lot of users at home would likely benefit from is the Chromecast. An implementation is available in VLC.

In principle it looks like the following is needed:

Implement a stream that can be downloaded via HTTP from our machine (i.e. we need a simple "HTTP server" that is able to serve the stream as one large "file". We can probably use the same codecs as for WFD, but we'll need a different container.
Implement discovery of chromecasts (using avahi)
Implement the command and control required to start/stop/restart streaming on the chromecast

Streaming freezes after a few seconds

I have tried with both the Screencast portal and the X11 interface, it streams successfully for a few seconds (albeit it lags a lot, whereas streaming from my phone is pretty smooth). After like 20-30 seconds my TV simply gets stuck on one frame (at least that's what I see). There are no errors/warnings in the output with the Screencast portal, except that audio can't be recorded fast enough. Tell me if I can provide any more information or how I can debug it, I find the project super cool :)

Virtual Screens?

It would be interesting to have the option to instead of casting the contents of the existing screen, to create a new virtual screen to be casted.

This would be useful for presentations and also cases where people have niche screen sizes, like ultrawidescreen monitors.

Destination address required

I basically get the same as #37. However I have installed the latest git version. The stick I'm trying to connect to is a microsoft miracast stick. I don't know what the exact name of that thing is. It just says Wireless Display Adapter on the side, but its some years old by now.

Logs from G_MESSAGES_DEBUG=all gnome-network-displays: gnome-network-displays.log

Notable from logs:

** (gnome-network-displays:25873): DEBUG: 18:11:18.284: Got state change notification from streaming sink to state ND_SINK_STATE_WAIT_SOCKET
** (gnome-network-displays:25873): DEBUG: 18:11:26.930: WFDP2PProvider: Peer removed

** (gnome-network-displays:25873): DEBUG: 18:11:29.879: Got state change notification from streaming sink to state ND_SINK_STATE_ERROR

Note: I had a compatible audio codec installed, but removed it in an attempt to isolate the issue. The logs are from when the audio codec was not available (which does not appear to limit the function)

Thanks for putting this together, it feels like we are very close!!!

This appears to be different than #30 as the error mentioned pipeline creation (which is not visible in my logs)

App Icon

As discussed on IRC, here's the app icon I've been playing with:

This would work for all the generic new app names proposed in #22, but if the name ends up changing, I can try something else.
