"Segmentation Fault" when trying to run #61

Closed EFJackson closed 1 year ago

EFJackson commented 1 year ago

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.

colinarelliott commented 1 year ago

I am having the same issue as you with a Raspberry Pi 4B. I got rid of the config error on line 17 by removing the blank character on the last line.

Now I'm just getting "Segmentation Fault", which I believe is some kind of memory error in compiling. Perhaps support for the model of Pi 4B we have is not yet complete?

root@cues-pi-cam:/opt/raspindi# . raspindi.sh 
Segmentation fault
EFJackson commented 1 year ago

I know the project states it isn't guaranteed to support 4B, so I suppose I'm being a little cheeky from the get-go by asking anything.

My experience was similar to yours, and that unspecific segmentation fault is where I gave up. I realise this is my own inability to patch past an unsupported Pi model however, I'm certain raspindi delivers admirably within its stated scope. Do let me know if you managed to find a workaround.

I've resorted to using the much-less-flexible Dicaffeine in the meantime. It's pretty bulletproof for straightforward NDI streaming (though uses the legacy camera stack that raspindi does not), but judging from your profile we're in a similar line of work and you might find its reliance on a GUI (and therefore a mouse and screen) and 'program' behaviour as opposed to library less comforting for touring or set-and-forget integration into event/theatre tech.

Cheers

rf152 commented 1 year ago

Thanks for reporting this.

Could you just confirm please:

The error with raspindi.conf is a known issue to do with the linebreak at the end of the file.

colinarelliott commented 1 year ago

I have not tried the precompiled binaries. That will be one of my next steps

mayromlo commented 1 year ago

Having Segfault issues as well. Hoping you can help. Fresh (today) install of Bullseye (32bit). All updates applied. Compiled from source.

Confirmed Camera is up and running on the current 32 bit version of Bullseye using: libcamera-vid -t 0 --inline --listen -o tcp://0.0.0.0:8888 to stream to VLC over network.

rf152 commented 1 year ago

I have just managed to free up one of my Pi 4bs, so I'll have a look at this hopefully in the next few days.

rf152 commented 1 year ago

Out of interest, why use 32-bit on a pi 4b?

mayromlo commented 1 year ago

It's the default selected by raspberry pi imager. I normally change it to 64bit (and I did initially). Had no luck with it, so I thought it might be a 64vs32 thing (messing about with the precompiled libs). So I redid the 32bit image, but the same segfault there too. I don't think 32 or 64 matters much since I'm using a 4GB model (I think the distro is exactly the same). If I were to use a 8GB model then yeah I would definitely need 64bit to detect the extra RAM.

Thanks for looking into this.

mayromlo commented 1 year ago

Not sure if this helps, but did manage to get a bit further.....still segfault at the end, but I get some output. I commented out "options->Parse(argc, argv);" in main.cpp (in src directory).....recompiled and now I get the options printed on the screen as follows (but it still segfaults):

Back to the drawing board :-)

rf152 commented 1 year ago

Ok, I've had a bit of time to look at this this morning, and it comes down to a breaking change in libcamera-apps, which has broken raspindi. I've now put in a fix (updated the header files that I include in this repo because libcamera-apps doesn't have a header package), which should resolve it for now.

I'll have to have a look at a more sustainable solution to this one, as I don't want to have to do this every time libcamera-apps changes something!

Segmentation fault

marcelpoelstra commented 1 year ago

Just to add some hopefully useful input

The last fixes from Feb24 indeed seem to fix the issues with Libcamera. However, I tried installing a fresh RPi4 this weekend, using the RPi (Sony) HQ camera and it seems to output NDI, however, without the video. Another breaking change in libcamera maybe?
This setup turnsout working fine using the old installation that has worked for over a year now (That SD card is gold now ;) )
By the way, in the new setup, when using the libcamera-vid tool the camera itself works like expected. Unfortunately It really seems something with Raspindi again, just can't get my head around it myself...

rf152 commented 1 year ago

How are you installing raspindi? With the script, or with the pre-compiled binaries?

rf152 commented 1 year ago

I've just tested it with a fresh 64-bit lite image on a raspberry pi 4b 2Gb memory, installed using the easy-setup.sh script.

I get a working video stream with all the default settings.

marcelpoelstra commented 1 year ago

The pre-compiled binaries do not seem to work in this situation at all, they always come up with the segmentation fault like mentioned many times above. So I tried thevfollowing use cases: 1) Install a fresh (latest) Raspberry OS (Armv7) 64 bit. Checkout git master, and run easyinstall.sh. Outcome: It's outputting NDI, but with empty video stream. libcamera-vid sending UDP to my computer works like expected, so no issues with the camera or libcamera in that respect. 2) Install a fresh (latest) Raspberry OS armhf (32bit) Same steps, same outcome 3)Install the previous version of RaspberryOS (the one that was current when you made the fix)
Same steps, same outcome. Problem here is that libcamera gets updated as soon as you install libcamera-dev, so ends up being the same version as with the newest Raspberry OS distribution 4) Install the previous version of RaspberryOS (the one that was current when you made the fix)
This time trying to prevent libcamera from updating by apt-mark hold libcamera , but this breaks things later in the process when libcamera-dev is installed, since that will be the newest version from the repo, and is not compatible with the older libcamera.

That is strange, how come this doesn't work with me? Please note I use the HQ camera, but do I need to set something different in the .conf file maybe? Never had to do that before to be honest

BTW what was the exact version of the image you used?

rf152 commented 1 year ago

I'm using the HQ camera as well. You shouldn't need to change anything in the configuration file.

I used the latest downloaded with the Raspberry Pi Imager, which is 2023-02-21.

marcelpoelstra commented 1 year ago

Bizarre..... I will just start all over from scratch again, but I really can't get my head around this. And also, the old SD card with the image and this software from a year ago also still works flawlessly....

Sorry to bother you, It must be some oversight here :S

rf152 commented 1 year ago

It's no problem - I'm keen to make sure it's not an issue with the software, as I want it to work for everyone as well as it seems to work for some!

It's an odd one, certainly. If you want I can image the sd card that I have and upload it so you can just image the SD card and know that it's a working raspindi, and you can then install any additional tools/software that you want to?

marcelpoelstra commented 1 year ago

That would be great indeed :) In the mean time I also will try again with a fresh install like you did

In any case I will post the result here.

marcelpoelstra commented 1 year ago

OK to make sure, what I just did :

1) Download the 2023-02-21. from here : https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm64-2023-02-22/

2) Use Raspberry Pi Imager 1.74 (Mac) to burn it on a microSD.

3) Boot the Pi with the fresh microSD

4) There is no git installed by default so I have to install that first : apt install git Reading package lists... Done Building dependency tree... Done Reading state information...

Apt updat was needed before I could install git.

5.) clone the raspindi repo

6.) Run easy-setup.sh

that fails.... after auto updating a multitude of packages and starting to compile :

So I'm afraid I'm really stuck here

rf152 commented 1 year ago

Interesting - thats an issue with finding the libcamera so, which is a new one on me. Can you try running sudo apt install libcamera-apps?

I'm just imaging the working SD at the moment, as soon as it's done, I'll upload it :)

marcelpoelstra commented 1 year ago

Cool, I'm currently doing a new test, this time not using the official Raspberry Pi Imager app, but using BalenaEtcher on my Macbook, and doing the config edits on the boot partition of the microSD manually. Somehow I want to make sure the official imager does not do any nasty tricks besides setting up Wifi and SSH. Update on this coming up

marcelpoelstra commented 1 year ago

OK, so I did the test again with the same image (23/02) and this time manually editing the ssh and wifi config on the bootfs partition of the microSD before putting it in the Rpi. This of course went fine, however, the rest of the outcomes are the same.
It ultimately failed on linking the executable again.

So we can rule out the official imager doing nasty (config) stuff in the background.

By the way, in all cases above I used libcamera-hello as well to make sure the camera is properly detected and working.

OK installing libcamera-apps did fix the linking issue.

However, I'm still getting an empty NDI stream :

some more debugging : When I tried to be smart and install libcamera-apps prior to running easy-install.sh, there is another linking issue popping up :

Interesting.

Try running sudo apt install libcamera as well (so install both libcamera and libcamera-apps).

What I don't understand is why they're not installed by default when on the image that I'm using (which is supposedly the same version) it is!

rf152 commented 1 year ago

I've now uploaded the raspberry pi image to https://github.com/raspberry-pi-camera/raspindi/releases/download/v3.0.3/raspindi-3.0.3.img.gz

Could you give it a go and see if it works as you expect it to.

Username is pi, and password is raspberry

marcelpoelstra commented 1 year ago

On your first suggestion, after flashing a fresh microsd:
sudo apt install libcamera0 Reading package lists... Done Building dependency tree... Done Reading state information... Done libcamera0 is already the newest version (0~git20230124+9b860a66-1). libcamera0 set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So I stopped here since that would not make any difference with my previous attempt where I first installed libcamera-apps before running easy-install.sh.

Now I'm up to the exiting part (hopefuly ;) ) and that is trying out your image. Please hold on !

marcelpoelstra commented 1 year ago

OK this is getting weirder by the minute.

Your image works, but also here empty NDI output.

While the camera is clearly working :

Does it display if you use the NDI tools to monitor it (NDI Studio Monitor on Windows, NDI Video Monitor on Mac)?

Good point, this one shows the video indeed :) Also in case of your image it shows the video in my OBS

Next up (for me at least) is what the difference is between your image and what I did myself before. So please ignore my last message about empty NDI

marcelpoelstra commented 1 year ago

Oh by the way, after requesting the NDI with the Newtec viewer it now also shows in the other tool......
