ad-vega / qarv Goto Github PK

qarv did not start on GitHub and the first releases were made by the make_release script, which made tarballs. GitHub allow releases to be made easily with git tags. CMake should be convinced to extract version from the latest tag as well; I like what the setuptools_scm plugin does for Python packages. The git tags use semantic versioning, so the API and ABI versions are in there, too.

It seems to belong to libavutils but devel files and libs are on the system.
Or so it seems.

Hi,

I'm trying out qarv with a Basler acA1920-155uc and experiencing the following issues when recording:

All of these issues have been noticed with a AOI of 1920x200.

First when rotating the image from the transform menu and recording, the result looks something like when the x y axis are incorrectly rotated, or the other axis is rotated twice, as a result the image looks scrambled.

Second, when recording with the AOI=1920x200, the recorded image starts rolling over on itself like this:

It seems to do this periodically at a set interval of a few hundred ms. By recording 10s @ 500fps (actual closer to <100fps (probably because of hardware limitations), the image rolls over about 20% of the height of the recorded AOI.

In both cases the picture in the preview in qarv looks like it should according to the settings.

As before, I am using a Basler acA1920-155uc camera, which by design is able to record 1920x1200 @ 155fps. By reducing the AOI, the camera can go up to thousands of fps. Currently it seems qarv can go to 999fps and qrv_player can play up to 99fps. I don't see a reason for these limitations, since most manufacturer SDK players don't have them either.

Aravis keeps adding GError parameters to their functions. I keep inserting nullptr 😁 . We should instead print some diagnostics if these functions fail. Emmanuel was kind enough to provide instructions.

moving #include <arv.h> out of the extern "C" block resolves this issue, but it really should not be nesscary.
I have breafly examined arv.h and qarv code and cant seam to find why this would happen as arv.h is a pure c header and i dont see how type_traits ends up included here

Aravis has gained new pixel formats. We need to add decoders etc. Also check whether defined numbers have changed because it's important for .qarv files.

Hi,
when building QArv with the Aravis from master branch I get this error:

I am using Ubuntu 18.04

Has anyone gotten this to work on OSX 11? I get to the cmake .. step. Anybody have any idea?

First of all, thank you for the great program! I already got it compiled and working nicely using Qt4 on Ubuntu 16.04.3.. However when building with Qt5 and making a Debian package with Checkinstall, I'm unable to launch qarv or qarv_videoplayer and instead just get the following:
qarv: error while loading shared libraries: libqarv-3.so.3: cannot open shared object file: No such file or directory

Here is the installation log where the libqarv-3.so.3 is installed:

Qarv also works when run manually from build -folder.

Any idea what I am potentially doing wrong?

When qarv was first written, gstreamer-0.10 was used in Qt. Because gstreamer does not support linking to multiple versions of the library, we could not make use of gstreamer-1.0 which had features that we wanted (although I can't remeber what they were after all this time). So we went our own way. Things are different now and we could probably make our lives easier by ditching the Q_SIGNAL based transport and custom widgets. Or not, it remains to be seen, but we should definitely check it out. In any case, it would be nice not to call into ffmpeg directly as it changes API rather often. It would also be nice if qarv could be used as a gstreamer source, or maybe a control panel for gstaravis.

Currently at least on Ubuntu it is not possible to open raw video files from file manager with "open with" and qarv_videoplayer being the target.

Does anyone know of better players for Linux that can play the raw files or TIFFs as video? I'm looking for a program that has similar functionality to any video editor program, where frames can easily be skipped with keyboard hotkeys.

These features would also be nice for qarv_player, along with the possibility of using a similar structure (or even code) as with VLC, where space bar works as play/pause etc..

For simplicity, QArv always used contiguous cv::Mat. This reduces performance of swscale decoder. Consider lifting this limitation. Most of the code should not really depend on this IIRC, but this needs to be checked and tested.

compiling fails with the error " ‘endl’ is not a member of ‘Qt’ "
i can get over this by replacing all Qt::endl with "\n".

on Ubuntu 20.04.1 I had to manually add libilmbase12_2.2.0-11ubuntu2_amd64.deb and libopenexr22_2.2.0-10ubuntu2_amd64.deb to run the program.
Also after install the library libqarv-3.so.3 needs to be moved to a library-folder before starting the program.

Hello! First of all, thanks for your work on this!

I was trying to run qarv over X11 forwarding, however, the window shows up entirely black and this message keeps repeating on the console:

composeAndFlush: makeCurrent() failed

Do you have any idea what could be happening here? I do not find anything useful on the internet. I am using Solus with all the qt5 packages updated and aravis 0.6.

Thanks!

I started a Qt project from scratch so I could test the API. Right at the first build time, compiler said it couldn't find gio/gio.h. After researching a little, I found out this is related to glib headers, so I included its paths on the .pro file:

INCLUDEPATH += "/usr/include/glib-2.0/" INCLUDEPATH += "/usr/lib/x86_64-linux-gnu/glib-2.0/include"

Now the compiler is accusing the following errors in gdbusintrospection.h:

/usr/include/glib-2.0/gio/gdbusintrospection.h:155: error: expected unqualified-id before ‘public’
GDBusSignalInfo **signals;
^
/usr/include/glib-2.0/gio/gdbusintrospection.h:155: error: expected ‘;’ at end of member declaration
GDBusSignalInfo **signals;
^
/usr/include/glib-2.0/gio/gdbusintrospection.h:155: error: expected ‘:’ before ‘;’ token
GDBusSignalInfo **signals;
^

I'm using Qt 5.9.5 at Ubuntu 18.04.

When using a build of 'qarv' from the master branch and the libraries from the latest Aravis 0.5.12 release, within seconds after starting 'qarv' the application receives a segmentation fault with the following stack trace from gdb:

I haven't yet had time to figure out how to use cmake to create a debug build to investigate further, but I assume there is a problem with a string being passed into the QArvCameraId::QArvCameraId() object constructor.
If I figure out the issue, I'll post back a fix.

This checkbox doesn't currently work properly: even when unchecked, the file is created, but it doesn't contain all the data. The use case of making raw video files without the information file is questionable, so this checkbox should be removed. The info file should always be created when raw video is recorded.

Hello,
Thank you a lot for the great app.

I suggest you a small fix, in order to allow build it with the newest aravis from repo aravis 0.8.0-1

and:

arv_gc_float_get_unit has changed and now it uses only ArvGcFloat pointer.

On some cameras (e.g. Basler acA1300-30gc) the camera features widget becomes excruciatingly slow when certain categories of features are opened. While the camera isn't that slow to respond, the number of queries that Qt's Model/View system sends is very large.
It may be that the QArvCamera implementation of QAbstractItemModel is suboptimal; further research is required. In that case, it may be possible to implement it more efficiently. If not, some kind of caching will be necessary.

I have everything working exactly as I would like. But when I add a second Teledyne Dalsa Genie Nano C4030 to my network (each camera is plugged into its own 1 GigE NIC), it will successfully recognize that there are 3 cameras (1 Fake, 2 Nano's). But when it loops through to assign the model and vendor, it fills in "" for the model and vendor on the new camera. Although, the camid will show the entire name, including the serial number (which is the only difference between the cameras...same firmware, same vendor, same model...but different serial number). But it errors out when checking if it is a camera.
If I use either camera alone, it's fine. If I reverse which nics they are plugged into, but only add 1 of them at a time, it works fine. It just seems to have an issue with both of them connected at the same time. I am currently stepping through the program to see if I can figure out what's going on.
Any ideas?

It would be good to enable more compiler warnings and fix reported issues. Examples: override keyword, deprecations, inconsistent class/struct declarations, switch statements, etc.

We've been putting off porting to Qt5 for far too long on the "it works" basis. Recently, Qt4 was masked in Gentoo and other distros are bound to go the same route sonner rather than later.
Once qarv builds and runs with Qt5, version 3 will be released.

I noticed that you did not mention windows but Aravis can be compile on windows,
this project is not compatible with windows?
