imx6qsabresd Linux camera interface

riteshpanchal — Mon, 08 Jun 2015 11:06:17 GMT

I am using imx6qsabresd board.

I want to make one application on Linux Platform that use on board camera to record video/image and store and stream that video/image.

Currently i am using fsl-yocto-3.14.28-1.0.1. I followed the step as per the "Freescale_Yocto_Project_User's_Guide.pdf" and created the QT5 Weston Wayland image. Also i successfully flashed it on SD card and i can run linux on imx6sabresd board. But i can't find any camera app.

So how can i get camera app which can record 1080p video and also stream. And if this kind of app is not installed in this image. how can i add this kinda app in this image??

and if there is not any app available how can i create some app like this for this board?

My final requirement is to make my own board based on imx6 with camera and wifi module only. And the running linux contains only modules related to these modules.

So how can i build images for my custom board and having only some selected modules and recipes?

I think you can write your apps and run it on QT5.

Qt 5 on Wayland

For the camera code, I think you can take the mxc_v4l2_capture which in the imx-test for reference.

Hi,

you can try Gstreamer for stream video from camera.

For example this:

gst-launch v4l2src device=/dev/video0 ! mfw_v4lsink device=/dev/video18 disp-width=1920 disp-height=1080

This command show video from v4l source to display or HDMI output.

Best regards,

Vilem

Thanks for the reply.

Making an QT app is an option but its more easy if any ready made app is available to record and stored videos from on board camera.

Because my final product will not having the display / hdmi output. I need to just stream or store video feed. But before that i need to evaluate the on sabresd board.

So can you tell me is there any app? and if yes how to install on QT5 Weston Wayland image running linux based on fsl-yocto-3.14.28-1.0.1.

or otherwise any guide to develop some test app?

Hi.. Thanks for the Reply,

After executing "gst-launch v4l2src device=/dev/video0 ! mfw_v4lsink device=/dev/video18 disp-width=1920 disp-height=1080" i got below message and nothing shows up on the display.

WARNING: erroneous pipeline: no element "mfw_v4lsink"

So can you tell me some details procedure to see on board camera feed in display on imx6qsabresd.

Hi,

please try this command:

gst-inspect

Then you will see available devices. It depends on version of Gstreamer and kernel. Now you need find output for v4l. I can be imxv4l2sink, too. This can be instead of mfw_v4lsink.

best Regards,

Vilem

As Vilem suggest, you can use the gstreamer to try the video streaming. You can search the "streaming" "gstreamer" in this community. There are many video streaming examples that using gstreamer and VLC. :smileyhappy:

Hi,

I have build image using following commands.

$ bitbake fsl-image-gui

as a build result i got following message

"Tasks Summary: Attempted 6778 tasks of which 42 didn't need to be rerun and all succeeded.

Hi Ritesh,

Now i have following questions

1. how can i see video feed on kit's lcd screen?

gst-launch v4l2src device=/dev/video0 ! mfw_isink device=/dev/video16

gst-launch v4l2src device=/dev/video0 ! imxv4l2sink device=/dev/video16

2. how can i store video or still image to sd card?

- You have lot of ways, how to store video to your SD card.

1. Insert SD card to your computer and mount in Linux. Then you can copy to File system (for example /home/)

2. Connect board to LAN and use scp command in Linux to copy over LAN.

3. how can i stream video feed to Ethernet?

- You can use gstreamer for streameng vide to LAN. It's depend on lot of parameters. Protocol, etc...

Best Regards

Vilem

Hi,

i got following error message after executing following commands.

1. gst-launch v4l2src device=/dev/video0 ! mfw_isink device=/dev/video16
     set color key
     MFW_GST_ISINK_PLUGIN 4.0.3 build on Jun 11 2015 17:33:41.
     WARNING: erroneous pipeline: no property "device" in element "mfwgstisink0"

2. gst-launch v4l2src device=/dev/video0 ! imxv4l2sink device=/dev/video16
Setting pipeline to PAUSED ...
and nothing appeared

I can see live video using below command

gst-launch imxv4l2src ! imxv4l2sink

And capture image using below command

gst-launch imxv4l2src num-buffers=1 ! jpegenc ! filesink location=sample.jpeg

I unable to use MIPI base embedded camera because this image doesn't having any mfw_xxx plugins.

In booting log 2 camera has been detected. so how can i use the above commands for other camera?

I find very difficult to use gstreamer in this board.

can you have any gstreamer user guide for freescale imx6 board.?

And my another questions are...

1. How can i add third party app in kit running fsl-image-gui image linux?

2. how can i add/remove recipe in fsl-image-gui image??

Hi,

If you want change source of video, you need change device (video0, video1, etc...). For example:

gst-launch imxv4l2src device=/dev/video0 ! imxv4l2sink

Please try all yours video devices.

Next questions:

1. If you have app for your processor, then you copy app to your file system and launch it.

If you haven't app for you board/processor, then you need build application with your cross-compilator (toolchain).

2. Please read this Training: Yocto Training - HOME

Best Regards,

Vilem

Hi,

I have tried gstreamer and i can stream Audio+Video over ethernet using following command

gst-launch imxv4l2src capture-mode=4 fps-n=30 ! vpuenc codec=6 ! queue ! mux. alsasrc ! 'audio/x-raw-int,rate=44100,channels=2' ! mfw_mp3encoder ! queue ! mux. flvmux name=mux ! tcpserversink host=172.10.10.143 port=5000

I have testing streaming in VLC player. But my problem is the feed is around 10 sec delayed at starting. And after 30-40 min it gets more delayed around 20-30 sec. And after around 45 or 1 hr sometimes audio not coming or sometimes audio + video both stopped. So can you tell me whats the problem?

I have searched for UDP rtps but i am unable to succeed. Can you provide instruction to install and use rtsp in yocto 1.7 based fsl-image-multimedia-full image?

In this image gstreamer v0.10 package is added. And i am unable to add rtsp. i refered the iMX linux user guide.

Then i tried for live555, ffmpeg but i think this pakage is not included.

How to check list of all included package?
