Hi,
I encountered an issue while installing this package on Arch Linux with Python 3.11.3. The installation fails with the following output:

Got the wrapper compiled (NDIlib.cpython-38-x86_64-linux-gnu.so), and examples running, with no errors after installing the NDI SDK on Ubuntu 20.04.

However, using the recv.py example I am having trouble receiving a video stream from a device broadcasting on our wifi network and I suspect the video format used is the cause. The example just shows a window with a looping video of a countdown.
EDIT: I must have goofed up the initial linking of the installed NDI SDK. Re-installed and now recv.py receives and shows the stream nicely.

My question still stands though:
Are there plans to support the NDI|HX linux driver? It doesn't seem to be supported in the current wrapper.
The driver can be downloaded from this site and the NDI SDK should pick it up from what the docs tell me.

Running on MacOS, ndi-python version 5.1.1.5 installed through pip/brew
pip install ndi-python
Requirement already satisfied: ndi-python in /opt/homebrew/lib/python3.10/site-packages (5.1.1.5)

I'm trying to implement an NDI router following the example in examples/router.py

I thought I had it set up correctly, and NDI players can see it, but they do not properly switch to the routed source.
I modified examples/find.py to print out the URL associated with the NDI source and discovered that it was being mapped to localhost (127.0.0.1)
e.g.:
dans-macbook:example dan$ python find.py
Network sources (12 found).
..
3. DANS-MACBOOK.BXB (HDMI1)
127.0.0.1:5961
4. DANS-MACBOOK.BXB (HDMI2)
127.0.0.1:5962

127.0.0.1:5964
7. DANS-MACBOOK.BXB (HDMI5)
127.0.0.1:5965
...

I do not find anything in the NDI SDK to specify the local address which should be used (am I missing something?).
Is this a problem with ndi-python, or is it a bug in the Mac version of the SDK?

Hi, I'm trying to use NDI to process some image from another software with CV2, so, at the moment, I just trasformed the received fram in numpy array and display it.
After a few seconds I get this message: Process finished with exit code -1073741819 (0xC0000005).
I'm using Python 3.9.18 on Windows 10 in a I7 7th generation

This is the code:

import sys
import numpy as np
import NDIlib as ndi
import cv2

def main():

if not ndi.initialize():
    return 0

ndi_find = ndi.find_create_v2()

if ndi_find is None:
    return 0

sources = []
while not len(sources) > 1:
    print('Looking for sources ...')
    ndi.find_wait_for_sources(ndi_find, 1000)
    sources = ndi.find_get_current_sources(ndi_find)

for i, s in enumerate(sources):
    print('%s. %s' % (i + 1, s.ndi_name))

ndi_recv_create = ndi.RecvCreateV3()
ndi_recv_create.color_format = ndi.RECV_COLOR_FORMAT_BGRX_BGRA

ndi_recv = ndi.recv_create_v3(ndi_recv_create)

if ndi_recv is None:
    return 0

ndi.recv_connect(ndi_recv, sources[1])

ndi.find_destroy(ndi_find)

while True:
    t, v, a, _ = ndi.recv_capture_v2(ndi_recv, 5000)

    if t == ndi.FRAME_TYPE_NONE:
        print('No data received.')
        continue

    if t == ndi.FRAME_TYPE_VIDEO:

        print('Video data received (%dx%d).' % (v.xres, v.yres))
        ndi.recv_free_video_v2(ndi_recv, v)
        image = np.copy(v.data)
        cv2.imshow('NDI', image)
        continue

    if t == ndi.FRAME_TYPE_AUDIO:
        print('Audio data received (%d samples).' % a.no_samples)
        ndi.recv_free_audio_v2(ndi_recv, a)

Hello, i want recv two single together in python.How can i do?

Hi, for some reason I can't set the ndi_name property for the NDIlib.RoutingCreate object.

Example:

if not ndi.initialize():
   return 0

route_settings = ndi.RoutingCreate()
route_settings.ndi_name = "test"

Result:

route_settings.ndi_name
>>> '`;\x12\x1d'

I'm using the develop branch code with NDI SDK 4. Any ideas on how to fix this?

Hello. Thanks for this library.

I'm running it on my Windows 10 using an RTX3070 but after the cmake and the build configuration for my OS I'm not really able to call the functions of the library. I can import it using the build files but when I run (e.g.) ndi_send = ndi.send_create() I get this error:

Traceback (most recent call last):
  File "ok.py", line 19, in <module>
    ndi_send = ndi.send_create()
AttributeError: module 'NDIlib' has no attribute 'send_create'

I'm importing through import NDIlib as ndi with a local folder

<pyfile>
<NDIlib>
    <NDIlib.cp35-win_amd64.pyd>
    <NDIlib.exp>
    <NDIlib.lib>
    <Processing.NDI.Lib.x64.lib>

Any idea what is this?
Thanks

Hi There,

I can receive an audio object;

while True:
# type, video, audio, metadata
t,v,a,m = ndi.recv_capture_v2(ndi_recv, 5000)

if t == ndi.FRAME_TYPE_AUDIO:
print("Audio data received (%d channels %d sample rate)." % (a.no_channels, a.sample_rate))

But i cant seem to do anything with it;

print(a.data)

results in;

AttributeError: unreadable attribute

Is this by design/has it not been implemented?

(BTW thanks very much, im loving this project!)

Python 3.11 is out and I'd love to use this NDI wrapper with the latest improvements to Python.

Thank you!

I'm having trouble finding the sources using the example code.

The environment is Ubuntu 20.04 and latest ndi-python.

I can find the ndi source with obs studio and also the avahi in the terminal:
❯ avahi-browse -a

• wlp0s20f3 IPv6 mevo-24V3K _ls-cameraman._tcp local
• wlp0s20f3 IPv6 mevo-24V3K _mevo-studio._tcp local
• wlp0s20f3 IPv4 mevo-24V3K _ls-cameraman._tcp local
• wlp0s20f3 IPv4 mevo-24V3K _mevo-studio._tcp local
• wlp0s20f3 IPv4 MEVO-24V3K (Mevo-24V3K) _ndi._tcp local

the ndi.find_get_current_sources(ndi_find) will always return empty list and i'm not sure where to start debugging.

Thanks in advance for any suggestions.

Hi! I'm sending video frames using send_video.py and trying to receive them using either recv.py or recv_cv.py. On the sending side, it is printed that frames are being sent like this:

But on the receiving side, it is only showing 'Looking for sources' when running both files like this:

What should I do?

Hello,
I am noticing something not quite right with the send_audio_16bpp.py example. I have installed on both Windows and Raspberry Pi, and testing with NDI Monitor on Windows.

The audio is not silent, but instead sounds like a taser. Same behavior coming from both Windows and Raspberry Pi. If I run the C++ NDIlib_Send_Audio_16bpp example, I get a source of silent audio.

Anybody else experience this?

I've come across this problem several times while developing an application but i've always just let it pass since it's a debug problem. I'll open this issue since its becoming more prevalent:

Example:
source_object = ndi.Source() source_object.ndi_name = ndi_name print(source_object.url_address)

Expected Behavior:
print(source_object.url_address) should print None or output an error

Actual Behavior:
Exits the application immediately
When debugging using VS Code and PTVSD, Server[1] closes unexpectedly

I compiled the module successfuly but attempting to load it while in the same directory as the so fields yields the below error.

Traceback (most recent call last):
  File "input.py", line 3, in <module>
    import NDIlib as ndi
ModuleNotFoundError: No module named 'NDIlib'

TLDR: The example code is incorrect for the current implementation and does not align with the original NDI spec. This means it is easy to create a memory leak if you're using the example code.

In the NDI SDK documentation, they specifically call NDIlib_recv_capture_v3 (or NDIlib_recv_capture_v2) with a receiver and then the pointers for each frame. You can also supply NULL if you don't want a frame.

However in the code base for ndi-python we specify ALL 3 pointers, which means we need to free all 3 of these pointers.

In the examples folder, we do not explicitly free them, so there is potential for memory leaks if this is running for a long time (I got to 10GB after 17hours while testing)

Suggest changing the C++ implementation, or changing the examples so that the other 2 frames are freed.

For anyone looking for a quick solution in their own code you can do something like:

(
    frame_type,
    video_frame,
    audio_frame,
    meta_frame,
) = ndi.recv_capture_v3(ndi_connection, 5000)

# As this implementation of NDI implicitly gives you ALL 3 frame types
# You must make sure you free them, else you will get a memory leak!

if frame_type == ndi.FRAME_TYPE_VIDEO:
    # do stuff
    ndi.recv_free_video_v2(ndi_connection, video_frame)

if frame_type == ndi.FRAME_TYPE_AUDIO:
     # do stuff
    ndi.recv_free_audio_v3(ndi_connection, audio_frame)

if frame_type == ndi.FRAME_TYPE_METADATA:
     # do stuff
    ndi.recv_free_metadata(ndi_connection, meta_frame)

According to your example, i can get image by recv_capture ,but it depends on how the while circulation fast. if a ndi resource is playing a video, how can I get a while video to save as v1.mov in local file.

Thank you for everything.

When sending images, the FPS limit seems to be 29,97 regardless of resolution.
Is there any way to increase the upper limit of FPS? Or is this a NDI specification?

There are many similar problems online, and they mostly seem to be solved by downgrading specific packages or installing cmake.
My current packages are all updated. Is there any help...?

ERROR: Failed building wheel for ndi-python

Failed to build ndi-python
ERROR: Could not build wheels for ndi-python, which is required to install pyproject.toml-based projects

I have seen the same error in windows machine also.

Please provide solution to fix this issue.

Thank you 😃

CMAKE doesn't build with 64bit python version:

CMake Error at lib/pybind11/tools/FindPythonLibsNew.cmake:127 (message):
  Python config failure: Python is 64-bit, chosen compiler is 32-bit
Call Stack (most recent call first):
  lib/pybind11/tools/pybind11Tools.cmake:16 (find_package)
  lib/pybind11/CMakeLists.txt:33 (include)

Same issue when installing through PyPy's pip or building yourself.

"Error in configuration process, project files may be invalid" CMakeOutput.log contains nothing either. Win 10 x64. CMake v3.20.0-rc1 using the GUI.

Select source downloaded from git, select empty folder as output, click configure, get error.

Edit: also tried in debian with the same error.

Install module more easily

I am trying to run the recv_cv.py example on Ubuntu 20.04 and I keep getting a frame which displays the error "Video decoder not found please visit ndi.tv/formats for help and information." Do you have an idea on how to solve this? Thank you.

The current FindNDI.cmake will compile fine on aarch64-rpi4, but requires modification to include the arch. Could we add it as a supported aarch for building, as it works just fine when modifications are made.

example modification to FindNDI.cmake that worked:
set(NDI_ARCH "aarch64-rpi4")

set(NDI_LIBRARY_DIR "${NDI_DIR}/lib/${NDI_ARCH}-linux-gnueabi")

Currently the cmake file does not do arch, only 32 or 64 bit, as far as I can tell.
