Are there any plans to add USB camera support?

Expose more of the options to be configured by the user (if desired):

• Auto White Balance
• Saturation
• Sharpness
• Contrast
• Brightness
• ISO
• Exposure Mode
• Metering Mode
• Rotation (#7)
• Mirror
• Video Stabilisation

Describe the bug*
I think the segfault from issue 49 happens on line 162 of main.cpp. Commenting that out results in a bad_alloc on line 134 of main.cpp. That's as far as I could get with my limited knowledge of C++.

Raspberry Pi OS Lite (64bit) - Debian Bullseye on a Raspberry Pi 4B (2GB) (I switched in the 64bit NDI modules as I mentioned in my other issue.

My original device (CM4 4GB/32GB) is still working flawlessly, I have not installed any updates or patches, and will not until this starts working...

hello, is there the possibility to change the parameters of the camera, like the contrast or the color thanks to a python command ? before installing Raspindi I used the command

CONTRAST IMG -100 - 100 (step1)

def imgSetContrast(self,m):
    if -100<=m<=100:
        subprocess.call(['v4l2-ctl', '--set-ctrl', f'contrast={m}'], shell=False)
        self.imgContrast=m
        print (f'Contrast={m}')

necessarily now it is no longer valid
thank you for your help and your work

Sorry for putting this in the issues tracker (feel free to mark this as closed). Just wanted to say that this is super awesome as the NDI SDK isn't even available for ARM processors anymore. This really turns $30 board with the really nice high quality pi cameras into powerful tools for livestreams at events. Keep up the good work (already made a public GUI for this btw ;) )

could you just drop a word whether this solution is meant for raspberry camera modules or USB connected webcams also and how to configure?

Hello! I'm getting this issue I'm not able to solve... Does anybody know how to fix it?

Thank you! 🙏

Is your feature request related to a problem? Please describe.
I would like to be able to adjust camera settings on the fly, is this possible? or do we need to change the config file and reload the service?

Describe the solution you'd like
Ability to adjust live, via control app, python interface, or some sort of web interface?

i get the message
cp: cannot stat 'lib/raspicam/*': No such file or directory
Done

on a raspberry zero with raspberry OS lite.

after having executed ./easy-setup.sh

what i could have done wrong ?

Thanks a lot in advance

Describe the bug
The preview tally status is not updated correctly. Program tally works as expected.

To Reproduce
Start raspindi on the Pi in a terminal window, and observe the tally status being printed to stdout.
Create two scenes in OBS, one containing the raspindi source, the other one empty.
Cue the raspindi scene into the preview. The PVW tally shows "1", PGM tally is "0". Ok so far.
Cut into the raspindi scene. The PGM tally shows "1". PVW tally remains at 1, wrong!
Cue the empty scene into preview. Still the PVW tally does not go back to zero.

Expected behavior
PVW tally should be a zero when not cued.

Additional context
Might as well be an OBS bug, can't test with other tools atm.

Hi! I wanted to try and get this working but I'm running into the following message when I try to run raspindi.sh:

/opt/raspindi/bin/raspindi: error while loading shared libraries: libcamera.so.0: cannot open shared object file: No such file or directory

I'm doing this on a currently fresh Raspbian Bullseye Lite install. I found this issue from another project that might suggest something has changed concerning libcamera in Raspbian. But I'm not skilled enough to look in your source and try to correct for it, if that is even the problem.

I've tried the precompiled files, easy-setup script, and step-by-step instructions each on clean installations but I continue to get to the same error message.

I might be overlooking something very basic here. Sorry if that's the case.

Something that would really make this project shine is the ability to add audio along with the video source, this way full microphone and video setups could run just off the raspberry pi! This might be a bit much to request but if its possible I bet it would be a great addition.

Another feature could be the ability to see all the config options or pass options in the command line. The changelog shows that you can add config parameters but doesn't say where.

I Tried to use the compiled version (on raspberry pi 4 running bookworm) but there is a lib compatibility error:

./raspindi-aarch64: error while loading shared libraries: libcamera_app.so.1.2.1: cannot open shared object file: No such file or directory

Then I tried to build it as well and it seems there was again some breaking changes in libcamera. Or I'm doing something wrong ?

Is it possible to rotate the camera?
Thanks for sharing.

Is there a way to make the delay more deterministic? Maybe by timestamping the NDI stream somehow and then making sure all of my PCs are using the same NTP source?

I'm having the issue that I have to modify the delay on a weekly basis to get the RPI-NDI camera (on the same gigabit switch as the streaming PC) in sync with the audio, which is captured directly through an audio interface (not connected to the RPI). It is usually around 333ms, but this past Sunday it was more than 1s, while nothing changed in the hardware or software setup on either the RPI or the streaming PC.

Clean install of Debian GNU/Linux 11 (bullseye) 64Bit on a Pi4B

Everything appears to be ok. I can grab a still image from the camera with libcamera-still -o test.jpg

raspindi appears to start cleanly.
I can see the NDi source available in NDi Studio Monitor

But I have no image at all, black screen.

What am I missing?

My RPI 4 running raspindi has been working well for a few months now, until about a week ago.

Symptoms

raspindi source is detected, but video is just black. Other sources, like NDI's own screen capture, is still working.

What changed?

The only thing that changed was a recent windows update, although I'm not sure which one. It stopped working on multiple Windows PCs, while continuing to work on other Windows PCs and all Linux PCs (using the exact same RPI4).

• The Windows PCs on which it does NOT work are all on update 10.0.19042.
• The Windows PCs on which it DOES work are all on update 10.0.18363.
• It's working on LinuxMint.

Whose fault?

At first, I though this was a problem with the obs-ndi plugin that I'm using. See DistroAV/DistroAV#651 . But NDI Studio Monitor is showing the exact same symptoms.

Since nothing changed in raspindi, it's probably not the raspindi's fault.

However, since other NDI sources are still working, it might be possible to get this working again from raspindi's side?

With the announcement today of NDI 5, I would like to look at using NDI 5 as the library.

It reports to have performance improvements, as well as new features.

Describe the bug
Running /opt/raspindi/raspindi.sh hangs in the terminal; nothing happens.
This is on a Raspberry Pi 3B with a Pi Camera Module 1.2.

To Reproduce
Steps to reproduce the behavior:

1. Follow installation instructinos based on Raspberry Pi OS; assure no errors
2. Run /opt/raspindi/raspindi.sh

Expected behavior
Something happens.

Additional context
Should this work with a pi camera module?

Describe the bug
Modifying /etc/raspindi.conf does not change the framerate of the NDI stream.

To Reproduce
Steps to reproduce the behavior:

1. sudo nano /etc/raspindi.conf
2. Change "fps" to 25 (line 5)
3. exit, save, restart raspindi
4. NDI stream still at 29.97p

Expected behavior
I would expect the fps to change accordingly.

Additional context
Changing the size of the video works (i.e. 1920x1080).
Also changing rotation and/or mirroring works.

I have also changed tried altering the name of the parameter in line 5 (fps, framerate, frame-rate...) - to no avail.
I also tried changing the format of the framerate to 25.00 - also no difference.

thanks, ahoi, j

hi, I am trying to deploy two raspberry as cameras for a small church in the center of Madrid (spain), our idea is to broadcast the sunday by instagram, for this we have two raspberry with camera and a PC, in the pc we have obs last version with the plugin: https://github.com/obs-ndi/obs-ndi, before it worked fine but with the last versions we got errors compiling so now we move raspberrpi os to image (raspindi-3.0.3.img.gz) and raspberry works well but we start OBS...

Hi - Really great implementation, works a treat and stable. I was wondering if you had looked at using the encoder h/w on the pi ? Taking a look at the stats it appears is all CPU and so not really possible to get a smooth stream on a Model 3 above CIF (352 × 288) ?? The thought would be to use the mmal library and offload to the GPU/VPU?

Is your feature request related to a problem? Please describe.
'illegal instruction' when running raspindi on piZeroW

Describe the solution you'd like
build opt. for PiZeroW to support addition Pi models

Describe alternatives you've considered
Not using PiZero : -) - It's possible the single core won't be up to the task, but it stills has GPU and v2.0x is making full use to hopeful of 1280x720 @ 25fps is possible

Additional context

With buster onward, libcamera is the new method of accessing the camera. Need to investigate the move to libcamera from mmal functions directly.

This will bump raspindi to v3, as it is a major change

I get this error when running build.

pi@raspberrypi:~/raspindi $ sh build.sh
src/main.cpp:17:10: fatal error: libconfig.h++: No such file or directory

Hi, really cool project and exactly what I need for something I'm working on.

When trying to get this running on a fresh Bullseye install on a Pi 4 Model B, after following the step-by-step instructions, I get the following:

Parse error at /etc/raspindi.conf:17 - syntax error
Segmentation Error

The extent of my troubleshooting (hampered by a lack of skill) on this has been tracking down the reported line, which is:

# mirror: "none"; // Options: none, horizontal, vertical, both

I've tried the various listed options, as well as removing the line entirely and that hasn't done the trick.

I appreciate this is probably less a bug report and more a matter of my own inability, but any advice would be greatly appreciated nonetheless!

Edit:
With a little more fiddling, I removed the hash and space prior to each option line in raspindi.conf. This may or may not have been a good idea, but it has left me with solely Segmentation Fault as an error when trying to run raspindi.sh

Couldn't say if this was useful information at all.

I have used the official imager to setup a new Pi 4 (4GB) running Buster lite three times: SD card 64bit, SSD 64bit, and SSD 32bit. After the machine comes up the first time, I apt update/upgrade, install git, and follow the install instructions given on this repo. For 64bit, I needed to do what was mentioned here:

#45

But, other than that, I think I'm working with clean installs that are free of any accidental misconfiguration.

The camera works. It has been working fine with a Pi 2, and I can use libcamera on the Pi 4 to pull images and video. Yet, I'm getting this every time I try to start raspindi:

Options: verbose: 0 info_text:#%frame (%fps fps) exp %exp ag %ag dg %dg timeout: 5000 width: 1280 height: 720 output: post_process_file: rawfull: 0 preview: none qt-preview: 0 transform: identity roi: all metering: average exposure: auto ev: 0 awb: auto flush: false wrap: 0 brightness: 0 contrast: 1 saturation: 1 sharpness: 1 framerate: 25 denoise: off viewfinder-width: 0 viewfinder-height: 0 tuning-file: (libcamera) lores-width: 0 lores-height: 0 mode: unspecified viewfinder-mode: unspecified bitrate: 0 profile: level: intra: 0 inline: 0 save-pts: codec: YUV420 quality (for MJPEG): 50 keypress: 0 signal: 0 initial: record split: 0 segment: 0 circular: 0 Segmentation fault

I've been around Linux and programming for many years, but I don't claim to be any great sage. To me, Segmentation Fault speaks of a memory management problem. So, I ran memory tests - which the device seemed to pass. I was initially trying to use a 64bit OS, and I know there are differences in how 32/64bit relate to memory, so I switched to 32bit. Didn't help, same "Segmentation fault". I wondered if maybe my somewhat cheap SSD was at fault, so I tried it on a standard SD card. Didn't help.

I'm going to try a Pi 3, to hopefully prove whether my procedure can work. But, I still want to get a Pi 4 working. The readme references latency on a Pi 4, so someone has got it to work. Was that pre-Buster? What am I missing?

I hope I'm not missing something stupid. I've tried to do my homework to not waste anyone's time. But "Segmentation fault" isn't highly descriptive for a Google search. Can someone tell me how to get a more verbose output, at least?

Thank you!

I followed the steps on the README to run raspindi from the binary. I have a raspberry pi 4 with a fresh install of raspbian bullseye 64bit.

• ran uname -m and my arch is aarch64
• download libndioutput-aarch64.so into /usr/lib
• download libndi-aarch64.tar.gz and unzip into /usr/lib
• download raspindi.conf.default and mv to /etc/raspindi.conf
• download raspindi-aarch64 and mv to /usr/bin/raspindi. run chmod a+x
• run raspindi

result:
root@camera2:/etc# raspindi
raspindi: error while loading shared libraries: libencoders.so.1: cannot open shared object file: No such file or directory

I've tried to search for a debian package that contains this file but I haven't had much luck

I used the latest raspbian bullseye 64bit image. I used the easy-setup.sh script, which installed several libraries (I've doublecheked that all of the compile and runtime libraries listed on the README are installed). when it executes the build.sh I get this compiler error:

Am I missing a library? Or do I not have a correct version?

Hi,

Is it possible to capture 2 ndi camera's (thru a switch) and stream these to an ip with a raspberry?
With this code I mean or is this beyond the capacities of this hub?

Kind regards,

Hi - newcomer to Raspi but long history in SW eng.

Seems this implementation uses mmal which is specific to the onboard camera.
Since I have a load of C920s spare I was wondering how feasible it would be for me to convert this over to use Webcam input.

Suspecting the answer is just go buy the onboard camera.

We are getting a pair of PTZ cameras for our livestreaming operation and was looking for a way to utilise the Webcams as local closeups for our worship band.

I wanted to apply the changes described below for my arducam camera, but since raspindi doesn’t seem to use “raspstill”, the changes don’t take affect. Is there a way to apply these changes via raspindi.conf file?

Is your feature request related to a problem? Please describe.
I'd like to run multiple pi's to have multiple video streams in the same network. I can do this by changing the video stream name in main.cpp to, for examples Video Feed 2, build and install again; and then I can run two.

Describe the solution you'd like
Currently, without doing the above, when i try this, the first camera works but the second does not; the application runs but I don't see its NDI stream. I suspect this is because the streams have the same name?

Describe alternatives you've considered
Add stream name to the configuration file?

Additional context
Add any other context or screenshots about the feature request here.

I'm just trying this for the first time. I'm installing on a Pi4 Model B, running lightweight Pi OS (64 bit)

Following the 'compile your own' step by step instructions I get as far as "./build.sh" which generates the following output.

Is your feature request related to a problem? Please describe.
After successfully maintaining a stable stream on a pi4 w/HQ camera combo I started testing pi3B+ w/different camera modules I had on hand. Eventually I tested with a Lintest HD-1 hat and found that I could get a stable and performative stream but colors were unusable as in raspivid the HD-1 uses awb off, red Gain set to 1.0, and blue Gain set to 1.0, but gain control is not exposed in this project.

Describe the solution you'd like
MMAL_PARAMETER_CUSTOM_AWB_GAINS available (preferably modifiable with the config file)

Describe alternatives you've considered
I'm still trying to figure this out myself but I'm not having much luck, so the only other alternative I have is that I am going to explore some other HDMI -> CS-2 modules as well but that's more avoid the problem then an alternative solution.

Since this project has moved to use libcamera, could you please enable support for external USB webcams?
Support for using webcams via UVC and/or V4L2 would be a big plus.

Thanks!
