I.MX-qtapplication source code question

[kangmw086]

hi

my yocto version is morty(kernel 4.9.11)

build-x11.

After booting the x11, it checked the IMX camera application.
I found the image in the following path but not the source code. Can you provide it to source code me?

YOCTO_DIR/build-x11/tmp/work/cortexa9hf-neon-poky-linux-gnueabi/imx-qtapplications/1.2.0-aarch32-r0/

thangs.
regards.

I think there should have some example code in QT developer forum.

e.g. https://doc.qt.io/archives/qt-5.11/qtmultimedia-index.html

For the i.MX, there is imx-test package include the code examples of capture.

sorry, but it's not the software I'm looking for.

The software I want seems to be made by NXP.

In the attached picture below,

I want the source code for the iMX Camera application.

The second picture is the executed screen.

( yocto morty build-x11. kernel 4.9.11 )

thank you.

Sorry, we don't provide the source code.

[kangmw086]

Is there no source code?
Or don't you provide technical support for the source code?

Is it possible to give advice on implementing software such as camera switching, preview, recording, etc.?

For example, using Gstremaer? How to use and handle v4l2?

thank you.

We have the imx-test package in Yocto BSP. You can find the source code of V4L2 example there.

[kangmw086]

I checked the V4L2 example (mxc_v4l2_*.out).
I want to know how to make mp4, avi, and jpg in this example.

Can you help me?

regards.

Here is the Linux BSP release web page

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

You can download the documentation for the release version that you are using.

e.g.

The i.MX Linux Reference Manual​ also talk about the V4L2 driver and the unit test.  And the i.MX VPU API Reference Manual​ talk about the VPU API usage.
