homeworkc / lazycast Goto Github PK

Hi, first of all, thank you very much for the work.
It´s a realy nice thing.

I´ve tried to setup my Pi3 to a miracast receiver wich worked perfectly.
As soon as I startet to turn my Pi into a standalone network
(https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md) (so its not connectet to my wifi an can receive the miracast) lazycast wont work anymore.
Tried everything: just one dhcp, solutions from other issues. Nothing worked for me.
Both parts, lazycast and the accespoint both work separately.

hi, first of all, thank you very much for the work.
It would be great if it worked!µ

So after setting the permissions and installing the dependencies, i run the ./all.sh script.
First it asks for the pin code, and i can connect my android phone. For a brief moment, i then see the android screen and hear the audio on the RaspberryPI , but this quickly disappears and a new pin code is asked. Here the output from the terminal:

pi@raspberrypi:~ $ cd lazycast/
pi@raspberrypi:~/lazycast $ ./all.sh

Hi,
I'm very impressed by your project. It's the only miracast solution that works out of the box I've found.
I try to integrate lazycast in my raspberry pi project, which I developped for schools in germany (--> http://mediakit.education).
But at one point I get stucked....
I use the wlan0 device as a router to give internet acces to students and I want to use lazycast parallel to this network connection....
I've seen that lazycast is creating a second wifi-device. And it's obviously possible to use it parralel to an internet connection via wifi, so the wlan device can handle two different network connections.
Do you have any idea how can I solve this problem?

Greetings
Olaf Koch

Hi homeworkc,
lazycast is the tool I was looking for.
Many thanks for this project.
Some times the ssid of the raspberry is no longer visible and therefore no longer possible to connect.
I get this error message:

Traceback (most recent call last):
  File "./d2.py", line 161, in <module>
    serverport=serverport[-1]
IndexError: list index out of range
PIN:
31093781
PIN:
Failed to connect to non-global ctrl_ifname: p2p-wlan0-6  error: No such file or directory

If I try to stop all.sh with a Ctrl-c I get this error message:

^CTraceback (most recent call last):
  File "./d2.py", line 17, in <module>
    import socket
  File "/usr/lib/python2.7/socket.py", line 53, in <module>
    import _ssl
KeyboardInterrupt
PIN:
Failed to connect to non-global ctrl_ifname: p2p-wlan0-6  error: No such file or directory

I should restart the raspberry and it works again.

Bests regards

hi, i very much need this kind of software. Reading about Lazycast i thought, well let's try it. But in the documentation, nowhere is mentioned that one need to first compile the software, of course since there are no binaries delivered but only source code. So, before doing anything else, i first type "make" and hope for a succesfull compilation.. but no; i have copypasted the output, including many compilation warnings and errors, below. Any idea why this happens and how i can solve it?
Btw: if i compile it like this, including the warnings, i can't get lazycast working properly; the connection stays for few seconds (i can see the android screen and audio on tv) but then it falls away and connection is broken;

here the compilation output:

Hello, senior.Thank you for your project. It helps me a lot。
There's a problem，
How to connect two Android displays together

can we mod the script somehow to make it work on raspbian without desktop ? it should work on a console-only OS. For example it could call omxplayer.

Is it possible to set it up so you don't have to type a new pin or no pin at all

I'm using a rpi 3b+ with a fresh setup of Buster that I downloaded directly from the rpi site a couple days ago. So everything is a new fresh setup of raspbian. I've gotten this to the point of being seen by an android phone. When I try to cast to the pi I get a new window that opens and it stays white and the phone shows that it's connected. When i have the phone disconnect from lazycast, that window on the pi closes. Here's the readout of everything from the terminal window.

I've been tracing down that error above about a file not found. I've gone through libavcodec and libavformat. But now I'm stuck at this file file. I believe it's looking for older versions of ffmpeg, however I haven't been able to use an older version of ffmpeg for some reason. Any suggestions on this would be greatly appreciated.

First of all thanks and congratulations for this project ( i didn't manage todo make work other rpi3 Cast solutions)

I downloaded release 1.0.1 with git
I set player1 (h264 player didn't work)
With android redmi note 3 pro i succesfully connected from wireless display entering the pin. Both audio and video worked pretty well.

But when i disconnect from android raspbian Desktop is not shown, nor can i use keyboard to show any shell. Unique solution is rebooting rpi3 (yesterday i managed booting It with ctrl+ alt+ del)

Any advice? (Is this a bug)

Hi,

When I try to connect my wind10 pc, the programs finish by saying can't open display. The PC is connected to the device tho. Any Idea what may have gone wrong ?

The documentation does not mention how to build the project. It just says "Make all.sh, d2.py, player.bin, h264.bin, control.bin, and controlhidc.bin executable:"

On raspbian-nspawn-64, the architecture is aarch64 instead of starting with armv.

This causes d2.py always open VLC instead of other binaries. (Line 194 of d2.py)

More information on architecture info on raspbian-nspawn-64 -

i have freezes when streaming from my mobile phone(Redmi Note 8)
maybe there are some settings in config files that increase performance or something else.
thanks

Every start of lazycast with all.sh takes more time until I can establish a good connection.
Also the number of p2p-wlan0 grows. At the moment ifconfig shows p2p-wlan0-84...
How can I reset everthing to the starting values?

When I attempt to connect to my lazycast Rpi3, I get the error "couldn't connect to your device." I was hoping to change the interface the lazycast uses for its network to see if that would help, but I cannot find a way to change the interface.

Win 10 mirroring works perfect until I open a browser (Edge/Chrome) and try to play a youtube video...Local Videos are no problem.

First off, I just wanted to say thanks for your work on this amazing project!

As far as I can tell, the option for using alsa as sound output (presumably the default device) is ignored and treated as HDMI for the player player (see here), while it's supported for h264 (see here). Is there a reason for this?

At the moment, I'm trying to get USB audio working (I'm running on a Pi Zero W, so I don't have an analogue input, instead USB to analogue) but even with h264 it ends up going through HDMI anyway, so I wanted to try player. FWIW, a command like omxplayer -o alsa test.mp4 works just fine.

Any info much appreciated!

First off, thank you for your efforts to make this a useful casting app. I have high hopes that I can get it working. I've tried this install a couple of different ways. Using an RPi CM3+ with 2 wireless dongles (edup ep-n8508 and Edimax EW-7611ULB), an RPi3A+ with built-in wifi.
I typically have been using SSH to connect and install things.

I've tried this first using Raspbian Buster Lite with no success. Essentially wifi would not longer work after the

"sudo apt install network-manager network-manager-gnome openvpn openvpn-systemd-resolved network-manager-openvpn network-manager-openvpn-gnome"
and
"sudo apt purge openresolv dhcpcd5" commands.

I was able to run the all.sh with ethernet, but got the same error posted here #43 (comment)

I tried this on an existing system and with a fresh image, on the CM3+ and RPi3A+, wifi would fail around 89% finished with installing and wlan0 could no longer be found.

Using a fresh image of "Raspbian Buster Desktop with recommended software" I tried skipping those steps and could get to all.sh giving me a pin code, but I couldn't find the device on the network, so I went and installed network manager which again, kills wlan0 around 89% finished with the install.
Going into Advanced Network Settings in the Raspbian desktop I can then make a connection called the same name as the all.sh script will name it, make that a hotspot using the wlan0 device, and Cloned MAC address = "Stable"
I can also use a USB to Ethernet adapter to keep an internet connection on the device. After rebooting it looks like I can connect to the device as a hotspot, but the password is the one I have it in Advanced Network Settings, not a pin.
Also after that reboot, all.sh fails:
pi@Streamer:~/lazycast $ ./all.sh

Selected interface 'p2p-dev-wlan0'

The only way I can get a pin is by removing the Hotspot connection and letting wlan0 either just scan or be connected to an SSID.
There must be something I'm missing here. is there anything obvious from what I've mentioned that could be causing this problem?

My Windows 10 source, recognizes the raspberry as a wireless display, but it can't establish a connection between them. Can anyone tell me what the issue is?

I followed all the advice given in the readme.

Regards and thanks for your help in advance

Strajuck

Wondering whether this can work with rpi1 with wifi-usb dongle, or even with LAN.

Thanks.

Do you have or have tried to run lazycast on a buildroot raspberry?

thanks for your work.

Hello.

I found your lazycast tool and it suits my need perfectly. I want to connect my Pi3 to my ceiling mounted projector and use it as a wireless display for my Windows PC.

I didn't get it to work using Buster, having the same problem already mentioned not having Internet access anymore after downgrading. So I just used an older (stretch) Raspbian rom. Now it works up until the password is printed to the screen every couple of seconds.

In Windows 10, however, it says my PC does not support wireless displays (the laptop is 10 years old).
On my phone (Android), the lazycast does show up in the list of wireless displays, but when I click it it says "connecting" for a while (20s or so) and then stops. I am also never asked for the password.

Is it supposed to work on Android? Of is it Windows only?

After fiddling for 2 hours I took a break and went out to get some takeout. And guess what, in the restaurant there is a TV in the corner saying "connect your screen wirelessly". Tried it, and it worked on the first try. It says "connecting" for 3-5s, and then it's connected.

Any idea?

Download wpa_supplicant source as described in command.txt

Edit p2p_supplicant.c function wpas_p2p_mac_setup
After:
u8 addr[ETH_ALEN] = {0};
Add two lines:
os_memcpy(wpa_s->own_addr, wpa_s->conf->p2p_device_persistent_mac_addr, ETH_ALEN);
os_memcpy(wpa_s->global->p2p_dev_addr, wpa_s->conf->p2p_device_persistent_mac_addr, ETH_ALEN);

Add following option to wpa_supplicant.conf
p2p_device_persistent_mac_addr= wanted mac address

Now P2P Go device always = p2p_device_persistent_mac_addr
For example my conf:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=0
country=US
persistent_reconnect=1
p2p_device_persistent_mac_addr=3e:50:84:9d:7e:11
mac_addr=0
p2p_interface_random_mac_addr=0
network={
ssid="DIRECT-AO"
bssid=3e:50:84:9d:7e:a5
psk="yrf6u5IC"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
mode=3
disabled=2
}

it works, when i turn off my firewall in windows.
can you please list what protocols and ports i need to open in firewall ?

I just set up Lazycast, i installed the requirements and then did git cloned Lazycast and chmodded every thing

Have downloaded the repo onto my Rpi 3A but when I try can connect either my laptop or tablet it just say failed to connected.

lazycast successfully runs on RPi3, says it's ready and displays a pin.

When I go to "Cast screen" on my Android device it just keeps searching for the device and never finds anything.
I tried with 3 different devices, that are able to connect to other sinks.

Not sure what to do next or how to debug it.

Failed to connect to non-global ctrl_ifname: (nil) error: No such file or directory

I am using ethernet to connect my pi, since the wireless module has broken if that helps.

Hey, ii'm trying to implement this on last rpi 3b+ and take advantage on 802.11ac and 5ghz that this rpi offers. As far i can understand, i can add on the all.sh file "freq=5" to use 5GHz mode. Is it possible to add dual-band(2.4 and 5ghz) compatibilty? and is it possible to use 802.11ac p2p connection to have a more stable connection and better latency?

Another question, is it possible to add support to multigestures using UIBC? Is there any document regarding uibc that i can read?

I setup Lazycast on PI3 with 7" LCD and at start it works fine, i have my Win 10 desktop on the PI3 screen but after few min that i am working with it turns white with "untitled" in the caption and loos the desktop that i am streaming.
From connection it looks fine all is working just loosing the desktop stream, any idea?

Another issue i have is that it is not utilizing the compleet screen size, i have a black frame around the desktop image. any way to optimize that?
Nir

what mean?

wpa_cli set device_type 7-0050F204-1
wpa_cli set p2p_go_ht40 1
wpa_cli wfd_subelem_set 0 00060151022a012c
wpa_cli wfd_subelem_set 1 0006000000000000
wpa_cli wfd_subelem_set 6 000700000000000000

where i can read about wfd_subelem_set arguments? is there any information anywhere about "wfd_subelem_set"?

how do "key_mgmt=NONE"?
how do open security without password and any pin at all?

Hello, thank you very much for this great project.

I'm using my android phone to test that it's OK， occasionally no display on the pi desktop.
But when I use win10 as a source, win10 don't pop the window to enter pin code, but to enter it on the other end(Raspberry Pi).

Hello,
I tried lazycast and everything works very well -- thanks for your work homeworkc.
Only one problem: when I cast a screen, I always get a black Border of about 10% around the picture, no matter which resolution of the screen I choose -- even with the native resolution of the screen attached to the raspi. This happens to all players (I tried no. 1/2 and the omxplaxer, always the same).
This results in poor readability of text because some pixels are droped.
Is this a bug or a feature?
I thought that omxplayer is using fullscreen, but this seems not to be.
Best regards,
orlo11.

I used to work with my raspberry with lazycast from my win10 computer, it used to work but not anymore. The screen is seen but everytime I try to connect with the pin showing on the shell it has troubles
I tried on differents win10 pc and it's still the same

my windows 10 doesn't discover rpi3.
the display is ready is displayed on rpi3.

It works fine when raspberry pi 3 is rebooted. But everytime it takes time to display pin. Before that it goes on the loop like Available interfaces: p2p-dev-wlan0 wlan0 Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-wlan0-5' Available interfaces: 'INTERFACES' command timed out. Selected interface 'p2p-dev-wlan0' Available interfaces: p2p-dev-wlan0 wlan0 Selected interface 'p2p-dev-wlan0' OK Selected interface 'p2p-dev-wlan0' Available interfaces: p2p-dev-wlan0 wlan0 Selected interface 'p2p-dev-wlan0' OK
After waiting for 10-15 minutes, it finally shows pin and then works flawlessly when connected. Once disconnected, it does not work when I try to connect again and I have to reboot to make it work.

Can following issues be solved ?

• Making process to display pin fast
• To work again without rebooting when it is disconnected
• Some times lazycast doesn't show up even when the pin is shown

Do you accept new feature requests? Are you working on making this a set-and-forget product?

How much time do you spend working on this project?

Hello,
I gave lazycast a try.
I took a raspbian buster out of the box, did apt update and full-upgrade (all today 2020-01-31)
installed udhcpd, downgraded wpasupplicant via aptitude, installed lazycast 1.2 (and also 1.1).
When I connect from an android phone (Galaxy S7) I see messages in the terminal, where I started all.sh, but no picture (on the phone it looks like it would work).
Then I tried from a Win 10 machine. I can connect, but there only appears an empty white window with the title "Unbenanntes Fenster" (as my locale is de_DE -- means "Unnamed window"), the panel remains on the screen.
I can use the mouse, connected to the Raspi, to control the Win 10 machine, so the back channel works.
This happens whatever I choose as player. I even changed the "d2.py" to run omxplayer, but always the same result.
Does anyone know a solution? It seems, the player starts in a wron way.
Regards
orlo11.

my win 10 laptop connect a wireless display option cant see lazy_on_raspberrypi

I installed and set up the raspberry pi accordingly and this is what happenes:

1. surface pro connects to pi successfully
2. i see the mirrored screen on the pi
3. after 3 to 10 seconds the connection shuts down

I'm thankful to anyone trying to look into my problem.

I followed all the step in the main page, i see the rasp from my win 10 but can't connect after i insert the pin:

in yellow: not possible to connect

A very useful feature would be Miracast over Infrastructure, which is supported under Windows 10 1703 and later. In companion with Chromecast-like GUI this feature would make lazycast a very useful solution even in semi-corporate networks. Please consider adding it in future releases.

Hi homeworkc, Have you tested wps_pbc to connect? I use my android phone for testing, which is always fixed as wps_pin. I want to find a simpler way to connect, and it was a bit of a hassle to type the password every time.

Hi. When I try and connect my windows 10 laptop to lazy it works perfectly for about 15 seconds before the raspberry pi appears to drop the connection. Windows still thinks it is screen mirroring but the feed is no longer visible on the raspberry pi.

Hi.
First of all, thank you for your great work. This project is exactly what i'm looking for with expanding my home media center functionalities. Have you considered integrating your solution into XBIAN or any other distro? I'm having trouble using this with XBIAN. I managed to stream my screen using player=1, player=2 and player=3(omxplayer). The only difficulty that arises is that I need to have some player already opened and then lazycast somehow hijacks the screen and mirroring works. It works really great and I'm wondering if I could make this solution into something more generic.

Hi,
I was trying to improve the connection and make the streaming more smooth by using a usb wifi dongle. It was Asus USB AC53 Nano, however, even I disable raspberry pi's internal wifi, the program keeps looping in Available interface: wlan0... And there's no pin that shows up.

I would like to ask if it's possible to use an external wifi chip to use lazycast. Thanks!
