qtcam's Issues

Unable to install on Ubuntu 16.04

I was wondering if this application will be updated to be able to install it on Ubuntu 16.04

make uvccamera API devoid of Qt classes

I found it difficult to port the uvccamera.h and related camera source files to apps which does not use Qt. are QMap and QString necessary?

No extensions available for the selected camera

I have a See3Cam_CU20 (HDR). I compiled from source and Qtcam runs, but when I select 'Extension Settings', I get the message 'No Extensions available for the selected camera.'

It is the 2nd camera in my device list.

I can change the standard camera settings fine (capture resolution, frame rate...).

Issue when compiling the source

I get this error when compiling the source as per your INTALL instruction

videoencoder.cpp:216:85: error: ‘av_packet_rescale_ts’ was not declared in this scope
             av_packet_rescale_ts(&pkt, pCodecCtx->time_base, pVideoStream->time_base);

qtcam with error QEGLPlatformContext

Hello
I have Jetson-TK1 and 2 cameras See3CAM_11CUG
I use Tegra124_Linux_R21.7.0_armhf.tbz2
and Tegra_Linux_Sample-Root-Filesystem_R21.7.0_armhf.tbz2

we try to use the UVC camera project
we are working with android 9 and usb camera from missumi
with USB Camera application from play store we can see the video
we can read the usb camera information
but from the UVC camera project there is message “check no usb camera”
we found that the interfacecount it is zero!!!

final int count = device.getInterfaceCount();   for (int i = 0; i < count; i++) {      final UsbInterface intf = device.getInterface(i);      if (matches(intf.getInterfaceClass(), intf.getInterfaceSubclass(), intf.getInterfaceProtocol())) {         return true;      }   }   return false;}

can you help us please
thanks in advanced

Multiple images capture

I have wanted to capture multiple images for an indefinite time for which I thought I would put the system call imageCapture(CommonEnums.TRIGGER_SHOT) in qtcam.qml under a continuous loop which would result in the trigger pressing again and again with burstlength=1. But upon build, this does not work and the trigger just captures 1 picture.
Why is that?

Can't cross-compile this repo for arm platform running Yocto Linux

HI, Can I cross-compile this codebase on a custom Linux Mint distribution (Yocto build) on arm platform ? Do I need to follow any specific instructions ?
$ dpkg --print-architecture
amd64
Thanks

firmware update with fwupd

would be nice to have firmware update with
https://github.com/hughsie/fwupd
and
https://secure-lvfs.rhcloud.com/lvfs/login

uvccamera::sendHidCmd seems wrong

I'm tracing through the see3CAM_CU135::setFrameRateCtlValue (btw, love that the name for the doxygen comment doesn't agree with the function name)

// Monitor read file descriptor for 5 secs

if(0 > select(1, &rfds, NULL, NULL, &tv)){

should the 1 be hid_fd + 1 instead?
The way this is written, I think it just waits 5 seconds. Turns out, tracing, hid_fd was 0 in my instance (so this worked).

We return true/false, how does the caller know how many bytes were read? Should it?

Ubuntu 20 support

Do you plan to add Qtcam support for Ubuntu 20?

Incorrect frame rate for video recording

I want to draw your attention to the part of file "videostreaming.cpp", function "Videostreaming::recordBegin(int, QString, QString)":

    v4l2_frmivalenum frmival;
    enum_frameintervals(frmival, m_pixelformat, m_width, m_height);
#if LIBAVCODEC_VER_AT_LEAST(54,25)
    bool tempRet = videoEncoder->createFile(fileName,(AVCodecID)videoEncoderType, m_capDestFormat.fmt.pix.width,m_capDestFormat.fmt.pix.height,frmival.discrete.denominator,frmival.discrete.numerator,10000000);
#else
    bool tempRet = videoEncoder->createFile(fileName,(CodecID)videoEncoderType, m_capDestFormat.fmt.pix.width,m_capDestFormat.fmt.pix.height,frmival.discrete.denominator,frmival.discrete.numerator,10000000);
#endif

Video recording is independent of the FPS, which we choose in the ComboBox "frame rate", in the section "Video Capture Settings".

You can see an example:
If you run Qtcam, and then select the minimum value of "frame rate" (5-10 FPS), and start to record video, then the video will be recording with the basic (standard) FPS, but the camera itself will work with the FPS which we have pointed out earlier "frame rate". Because of this, the video file with an incorrect value FPS: video recording will be slower, and playing video file will be accelerated.
The same problem can be obtained by selecting a different value in comboBox "frame rate", different from the standard...

I think that part of the code, which I quoted above, should be replaced by this:

    v4l2_fract temp_interval;
    if (m_has_interval) {
        temp_interval = m_interval;
    }
    else {
        v4l2_frmivalenum frmival;
        enum_frameintervals(frmival, m_pixelformat, m_width, m_height);
        temp_interval = frmival.discrete;
    }
#if LIBAVCODEC_VER_AT_LEAST(54,25)
    bool tempRet = videoEncoder->createFile(fileName,(AVCodecID)videoEncoderType, m_capDestFormat.fmt.pix.width,m_capDestFormat.fmt.pix.height,temp_interval.denominator,temp_interval.numerator,10000000);
#else
    bool tempRet = videoEncoder->createFile(fileName,(CodecID)videoEncoderType, m_capDestFormat.fmt.pix.width,m_capDestFormat.fmt.pix.height,temp_interval.denominator,temp_interval.numerator,10000000);
#endif

startup problem and display issue on high resolution video

when using QTCam I am facing 2 issues:

1- the program startup takes a long time. also i have the following warning :
libpng warning: iCCP: known incorrect sRGB profile

second issue, when using ECON C80, C130 cameras or a logitech camera and i go to a high resolution (1920x1080 and higher) the camera display begin to lag and "framed" (frames are not continuous). even when i use mjpeg on high fps (30)

i am building the code on QT 5.9.2

Failure to build on 4.1+

I have this ECON camera: https://www.e-consystems.com/industrial-cameras/ov2311-monochrome-global-shutter-camera.asp

Following V4L2 doc https://www.kernel.org/doc/html/v4.9/media/uapi/v4l/control.html#example-enumerating-all-user-controls, the device tells me the only control available is BRIGTHNESS.

I expected to have control also on EXPOSURE_TIME. Is there a way to get control over it?

If yes, does this needs playing with hidraw-device-like properties? Is there a code sample in this repo related to this specific use case (modifying EXPOSURE TIME)?
If no, is EXPOSURE TIME control not supported on ov2311? Is this documented or intended?

'make install' installs into wrong qml directory

I compiled from source which proceeded fine, but when I ran 'make install' it does the following:

cp -f -R /home/jseng/qtcam/src/qml/qtcam /usr//qml/

It seems to not install into the /usr/share/qml directory. When I try to start the program, I then get an error that it cannot find /usr/share/qml/qtcam/Views/qtcam.qml

When I fix the makefile manually, the install works.

Can't compile on Debian Sid

Hi, currently on Debian 9 and completely unable to compile from source. There's an instruction to download a .run file for qt dependencies, and the file just doesn't work. A more detailed compiled instruction would be useful, or if possible to supply compiled deb packages would also be great.

ov5640 camera not detected

Hi
we have a ov5640 camera and we want to use it on a banana pi m64 board.
qtcam can always show capture using a usb camera we connected to our board but it doesen't recognize the ov5640 and it shows the name wrong and error "resource is busy".
we used another app (guvcview) to capture frame and it recognized the camera without any problem but for some reasons we can't use that app.
could you please tell us how to define the camera for your application?

Create Github release

Hello, Void Linux is interested in packaging qtcam.
I see that you have releases described in Release.ini and I was just wondering if you could tag a release on Github for the build infrastructure to pull from.

Thanks

to me

From what I can tell the uses for QAudioDeviceInfo were split up between QMediaDevices, QAudioDevice, QMediaFormat, and maybe some others.
There is a blog post detailing the overall changes to Qt Multimedia going into QT6 here:
https://www.qt.io/blog/qt-multimedia-in-qt-6

I would look through this post along with the Qt6 documentation for Qt Multimedia classes.

What is the update then ?

Hi

Thank you for contacting Qt Account Support.

According to documentation, the QAudioDeviceInfo class was deprecated
going into Qt6.
You can see here https://doc.qt.io/qt-5/qaudiodeviceinfo.html
[https://doc.qt.io/qt-5/qaudiodeviceinfo.html] that the dropdown to the
left only has 5.15 LTS as an option, the absence of Qt6 versions means
it is no longer included.

16.04 [avi @ 0x6383e00] No streams to mux were specified

I got this error on Linux Mint 18 (Ubuntu 16.04)

it was unable to record the video.

When in trigger mode, the video feed is not working?

I was wondering why the updated video feed does not update when I am in trigger mode? Is there a specific design consideration that I just don't understand? I think that feature would improve your application.

Problems with enableTriggerMode()

Hello!
I'm developing program for capturing images from two See3CAM_11CUG cameras. In my project I'm using Qtcam source code.
I'm trying to switch cameras to the Trigger mode using following method from uvccamera.h.
But write function returns -1 with error EINVAL.
Before switching to trigger mode camera is opened:
fd = open(device.c_str(), O_RDWR | O_NONBLOCK, 0);
After that the camera is initialized with the necessary exposure value and the pixel format is set to V4L2_PIX_FMT_YUYV.
Could you please tell, what could be the reason of such error? Maybe there are some necessary conditions that must be met before switching to the trigger mode?

Thank you in advance.

How to install qtcam on raspberry pi

I just started a project that uses See3CAM_CU51 that requires QtCam to open. I need to open it on a raspberry pi. However, I cannot use apt-add-repository on a raspberry pi. May I ask how I can install qtcam from the source code.

Thank you very much

trigger does not work

I have see3cam_CU51 model and I wired a few wires to some external GPIO pins to send triggering signals. Once in trigger mode on Windows e-camview software, sending the pulses triggers the camera and images are stored. But doing the same exact thing on QtCam software has no effect (same camera, same wiring etc.). Why QtCam does not respond to hardware triggering but Windows software does? Thanks

qtcam keep crashing when Color Space/Compression stay at MPEG

The default setting of qtcam was fine the view the camera image correctly.
However, when I try to change the "Color Space/Compression" under Video Capture Settings from YUVU to MPEG, the program crash.

And because the program kept the setting, so even if I restart the qtcam and select the camera, it crash immediatly.

I tried to purge the program setting by sudo apt-get purge qtcam, but this didn't works.

How can I remove the config to default?

Project MESSAGE: x86_64 bit libs
Project ERROR: Unknown module(s) in QT: multimedia qml quick

Similarly when installing dependencies the following error is obtained:
E: Unable to locate package qtdeclarative5-dialogs-plugin
E: Unable to locate package qtdeclarative5-qtmultimedia-plugin

Compile instructions

I think that more detailed and decoupled from Ubuntu/Debian compilation instructions should be provided into the INSTALL instructions.
Thanks in advance.

QML file contains feature which are not supported by QT Quick Designer

I'm trying to modify QTCam using the QT Creator application.

When I try to view the design tab on most of the Views images, I get the following warning:

Line: 193: This type (Timer) is not supported in the Qt Quick Designer. (M204)

as well as

Line: 220: Imperative code is not supported in the Qt Quick Designer. (M203).
Line: 223: ""
Line: 315: ""

Etc.

I'm using the community edition of Qt Creator found here: https://www1.qt.io/download-open-source/?hsCtaTracking=f977210e-de67-475f-a32b-65cec207fd03%7Cd62710cd-e1db-46aa-8d4d-2f1c1ffdacea

See3CAM_CU51: "Trigger Mode Enabling Failed"

I have used the See3CAM_CU51 camera and every time I attempt to go to click the button 'Trigger Mode' in the 'Extension Settings' tab and I get a Failure error of, "Trigger Mode enabling failed". What is the issue? I tried with 2 cameras and I still get this error.

Using the github qtcam I followed the instructions by compiling the code in the commandline:

change common.h LAUNCHPAD to 0
$ qmake
$ make

flatpak binarys

qtcam bundles various libraries

Hi. I am interested in packaging qtcam for Fedora and push it into Fedora official repository. I would like to ask you one thing about your software: the reasons why qtcam bundles various libraries. All main Linux distributions guidelines avoid shipping bundled libraries that already are shipped inside distribution's repository. Basically, the prohibition on bundling is there for several reasons:

security - we can fix the vulnerabilities in one place, the shared library, and every package depending on it is not vulnerable anymore;
forking - if everyone is bundling their own fork, it gets harder to fix bugs, including security vulnerabilities and it creates more work for every maintainer involved as the forks diverge;
general bug fixes and features - every package depending on a shared library gets the benefits of bugfixes and new features instantly (and we have the option to package a parallel-installable older version if a depending package can't be updated/fixed to work with the latest library version).

Concerning Fedora, the packaging guidelines are explained at https://fedoraproject.org/wiki/Packaging:No_Bundled_Libraries
