CameraBin error: "Failed to allocate required memory." with QCamera

henri · March 16, 2023, 8:27pm

With libcamera-still i can see the preview and control the camera but
this happens when i run multimediawidgets/camera example application
CameraBin error: “Failed to allocate required memory.”

Hardware:
Raspberry Pi 4
8GB Compute Module 4 (2GB ram)
CamArray Hat with four 64MB hawkeye autofocus cameras connected
SKU: MBS-SES-256
GTIN: 0618455044205
purchase link ArduCam 64MP Autofocus Quad-Camera Kit | MYBOTSHOP.DE, 374,95 €

Soft:
Latest 32-bit bullseye
Qt 5.15.2

as i tracked down the problem is with gstreamer v4l2 drivers as qcamera is using it and standalone gsteramer doesent work either with my arducams
the bug appears to have recently been fixed with 1.22.1 build at https://gstreamer.freedesktop.org/

v4l2h264dec: Fix Raspberry Pi4 will not play video in application

but i have yet no idea how to install that 1.22.1 version. the one i get with apt-get is 1.18

has anybody here countered this problem and knows how to fix?
or can you give me links with instructions how to build gstreamer from source and install the libraries since the latest gstreamer version i get with apt-get is 1.18

henri · March 16, 2023, 8:58pm

ok, i think i found the instructions to build and install gstreamer from source will try it out later.

@henri

Have you made any progress on this issue?
Has it been resolved?

henri · March 20, 2023, 12:06pm

I will try out the possible fix today/tomorrow. My plan is:

$ apt-cache depends libqt5multimedia5-plugins
libqt5multimedia5-plugins
Depends: libqt5multimedia5
Depends: libasound2
Depends: libc6
Depends: libglib2.0-0
Depends: libgstreamer-plugins-base1.0-0
Depends: libgstreamer1.0-0
Depends: libpulse0
Depends: libqt5core5a
|Depends: libqt5gui5
Depends: libqt5gui5-gles
Depends: libqt5multimediagsttools5
Depends: libqt5network5
Depends: libstdc++6

This means i have to

Remove libraries
sudo apt-get remove libqt5multimedia5-plugins
sudo apt-get remove libgstreamer1.0 libgstreamer-plugins-base1.0 libgstreamermm-1.0
just in case
sudo apt-get remove libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamermm-1.0-dev
Build and install gstreamer 1.22.1 from source following this guide in README:
Files · 1.22.1 · GStreamer / gstreamer · GitLab
Install the libq5multimedia5-plugins again
sudo apt-get install libqt5multimedia5-plugins

Will let you know if it worked.

henri · March 23, 2023, 4:12am

So this is where im at right now

sudo apt-get remove libqt5multimedia5-plugins
sudo apt-get remove libgstreamer1.0 libgstreamer-plugins-base1.0 libgstreamermm-1.0

Just in case

sudo apt-get remove libgstreamer*

VERY IMPORTNANT TO INSTALL meson as root otherwise will get build issue

$sudo pip3 install meson
$sudo pip3 install markdow typogrify
$sudo apt-get update
$sudo apt-get install ninja-build
$sudo apt install -y build-essential autotools-dev automake autoconf
libtool autopoint libxml2-dev zlib1g-dev libglib2.0-dev
pkg-config bison flex python3 git gtk-doc-tools libasound2-dev
libgudev-1.0-dev libxt-dev libvorbis-dev libcdparanoia-dev

libcdaudio-dev libdc1394-22-dev ladspa-sdk libass-dev
libcurl4-gnutls-dev libdca-dev libdvdnav-dev \

Make sure to get the tarball because checkout out 1.22.1 tag from git gave me problems i could not resolve.

$wget https://gitlab.freedesktop.org/gstreamer/gstreamer/-/archive/1.21.1/gstreamer-1.21.1.tar.gz
$tar -xf gstreamer-1.21.1.tar.gz
$cd gstreamer-1.21.1.tar.gz

FFmpeg didnt compile on my RPI4 (32-it OS), so to disable it cause got some ARMv proessor arhcitecture errors.

$meson builddir -Dgst-plugins-base:gl_winsys=egl -Dlibav=disabled
$ninja -C builddir
$meson setup builddir
$meson compile -C buildir

$sudo meson install -C builddir$ gst-launch-1.0 --version
gst-launch-1.0: error while loading shared libraries: libgstreamer-1.0.so.0: cannot open shared object file: No such file or directory

$sudo gedit /etc/ld.so.conf.d/randomLibs.conf
#add this line to the file or if the ibgstreamer-1.0.so.0 was installed somewhere else add that path
/usr/local/lib/arm-linux-gnueabihf
sudo ldconfig

$gst-launch-1.0 --version
gst-launch-1.0 version 1.21.1
GStreamer 1.21.1
Unknown package origin

When i try to run my app that uses QCamera this is the error i get:

Error: cannot create camera service, the ‘camerabin’ plugin is missing for GStreamer 1.18.
Please install the ‘bad’ GStreamer plugin package.

I will now try to compile and install the bad plugin package with -Dbad=enabled. But im not sure if it will fix this because it seems to me that when i install sudo apt-get install qtmultimedia5-dev this will automatically install and try to use the 1.18 gstreamer - this is what i conclude from that error message.

henri · March 23, 2023, 7:43am

$meson builddir --reconfigure -Dbad=enabled -Dgst-plugins-base:gl_winsys=egl,wayland -Dlibav=disabled -Dgst-plugins-bad:camerabin2=enabled
$meson compile -C builddir
$meson install -C builddir

And now my QCamera app cant even detect the camera… . Before this it would detect and camera would at least make a sound. but its silent now.

Can you reccommend me some other class I could use for this camera? I see some people have used the qcam code from lib-camera. Anybody have a working project setup with that code?

All i need is to have the cameras to be able to capture pictures and control zoom from my Qt application.

henri · March 23, 2023, 9:22am

I think ill try next to bring the fix commited to 1.22.1 into 1.18 gstreamer and build it from source with just that fix. cause its really just changing one row in 1 file.

Edward · March 23, 2023, 9:25am

@henri

I don’t know enough about GStreamer

But if you want to try this, I can give you some advice.

If you want to use qcam, it only takes a few steps

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
chmod +x ./install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p libcamera
./install_pivariety_pkgs.sh -p libcamera_apps
./install_pivariety_pkgs.sh -p 64mp_pi_hawk_eye_kernel_driver

then use direct

qcam

I have also written some examples about taking pictures.

henri · March 23, 2023, 10:45am

Tx, but what i will need to do is to take this QT C++ code from qcam\apps\src - libcamera/libcamera.git - libcamera official repository and put into my QT C++ app. Just a small problem is that if i build libcamera from source i do it with meson, but my application uses qmake so combining the two codebases might not be a trivial task.

So I just found out that the fix in gstreamer 1.22.1 that makes camera work with Qt is just one line in gstreamer source code. What i will try next is to check out gstreamer 1.18 source code, put that fix in it, compile and install since my qt app was able to reqonize camera when gstreamer 1.18 was installed. This is the fix if im not mistaken: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/67df248270491116af6099bf3bec5c740dfe3042

henri · March 24, 2023, 3:26am

This fix didnt work out. It was either the qt plugin didnt use it, this fix wasnt enough. Theres a lot of files had changed from 1.18.6 to 1.22.1 but i think i succeeded carrying that fix over. This is what i did:

# So the packages i compiled were not replace with packages from remote repo i installed with apt-get
sudo apt-get remove gstreamer1.0-plugins-good

# Now when i do
pi@raspberrypi:~ $ gst-launch-1.0 --version
gst-launch-1.0 version 1.18.6
GStreamer 1.18.6
Unknown package origin

# But after that removal the gst-launch-1.0 cant play back camera anymore. Maybe it was my "fix" in code that broke it. Ill roll that back and rebuild
# So what i did now is that i uninstalled everything related to gstreamer
sudo apt-get remove libgstreamer* libqt5gstreamer* gstreamer1.0*

# I just try to make as full install as possible

Anyways at this point i give up and work on some other stuff. maybe over time somebody will fix it for qt5 or ill try to use libcamera instead of QCamera or ill see if my camera works in qt6.

henri · March 25, 2023, 11:41pm

I tried the steps you described but got error:
-bash: /usr/local/bin/qcam: No such file or directory

Also tried to build qcam from source, installed it and ran it from command line but got some errors about
arducam_64mp properties json

henri · March 26, 2023, 12:01am

ok, the qcam with your script was installed to /usr/bin/qcam and it displays video. It works but the qcam i compile from source does not work with my camera. I tried both 0.0.4 and 0.0.1 versions. Can you tell me why?

when running qcam log i compiled from source:

Also i get the following error when i try to run your python examples:

pi@raspberrypi:~/Desktop/picamera2_examples $ python3 SavePng.py

I have 32-bit bullseye, kernel 5.10.something, RPI4 CM4

@henri

Are you using our github repository

I tested the manual compilation in the afternoon and found no problems.

henri · April 2, 2023, 1:48pm

I gave it one more try. Compiled qt5.15.2 from source, then cross-compiled it for RPI4, 32-bit bullseye 6.1.xx

Compiled gstreamer 1.22.1 from source that i thought has fix for it.

Then ran my qt app that uses Camera, i get the same failed to allocate required memory error.

Running gstreamer from command line gives the same error:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! fbdevsink

From this i conclude that the issue has not been fixed in gstreamer and i have to use libcamera qcam example to get qt into my raspberry qt app.

I managed to convert libcamera simple-cam meson example to QT project. I used chatgpt to convert meson.build to .pro file. For those in the future who are struggling integrating libcamera to qt i have uploaded the project to GitHub - henrihallik/simple-cam-qt: libcamera simple-cam QT project conversion.
Also chatgpt proved vital working through various linker errors that occured. So if u need more help , just ask openais chatgpt. https://chat.openai.com/chat

@henri

simple try:
write a CMakeLists.txt

cmake_minimum_required(VERSION 3.6)
set(CMAKE_CXX_STANDARD 17)

set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}" ${CMAKE_MODULE_PATH})
project(simple-cam)

find_package(PkgConfig REQUIRED)
pkg_check_modules(CAMERA REQUIRED libcamera)

#pkg_check_modules(CAMERA REQUIRED libcamera)
include(FindLibEvent.cmake)
find_package(LibEvent REQUIRED)


find_library(LIBCAMERA_LIBRARY libcamera.so REQUIRED)
find_library(LIBCAMERA_BASE_LIBRARY libcamera-base.so REQUIRED)

include_directories(. "${CAMERA_INCLUDE_DIRS}")

set(LIBCAMERA_LIBRARIES "${LIBCAMERA_LIBRARY}" "${LIBCAMERA_BASE_LIBRARY}")
add_executable(simple-cam simple-cam.cpp event_loop.cpp event_loop.h)

target_link_libraries(simple-cam "${LIBCAMERA_LIBRARIES}" event event_pthreads)

I really don’t have a lot of time to come up with some interesting examples, if anyone is interested, I hope to share them below.

I managed to compile this with QT creator installed on my RPI4

https://github.com/henrihallik/simple-cam-qt

It detects cameras when im trying to run it from terminal.
But when i try to run it from QT creator this is the error i get:

15:59:09: Starting /home/pi/Desktop/build-simple-cam-Desktop-Debug/simple-cam ...

Any Ideas why this happens?

Anyways this is the log i get when running from command line:
