hi everybody
i have TI DM368 board with LI-5M02 board and am using DVSDK_4_02_00_06 sdk
i already boot my board using NFS ..now i like to save the capture image to
SD card in Jpeg format... if you have any document or related link please
let me know...
Thankyou!!!
Regards
V.Natarajan
Hi Natraj,
You can capture Images from your V4L2 source and compress them as JPEG files and store them using the following pipeline:
gst-launch -e v4l2src always-copy=false num-buffers=1 chain-ipipe=true ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! dmaienc_jpeg ! filesink location=VGA_jpeg_file01.jpg
This pipeline stores your image to a file in your NFS root folder.
If you want to store it on an SD card, you have to mount your SD card, i have already explained that in here: http://designsomething.org/leopardboard/f/23/p/733/2657.aspx#2657
Assuming you have called your SD mount directory as /CARD you can run the previous pipeline but with the folder name:
gst-launch -e v4l2src always-copy=false num-buffers=1 chain-ipipe=true ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! dmaienc_jpeg ! filesink location=/CARD/VGA_jpeg_file02.jpg
Hope that is useful.Morteza
Hi Morteza
Thankyou very much for your reply... but i got this message after execute that your first command (store to root foler)
WARNING: erroneous pipeline: no property "chain-ipipe" in element "v4l2src0"
V.natarajan
Hi Natarajan,
Try removing the property with error and run the pipeline again:
gst-launch -e v4l2src always-copy=false num-buffers=1 ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! dmaienc_jpeg ! filesink location=VGA_jpeg_file01.jpg
But are you sure your gstreamer is working? have you tested other pipelines on it before? Report back the feedback if there is any error
Morteza
hi Morteza
i used this this line
gst-launch -e v4l2src always-copy=false num-buffers=1 ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! jpegenc -e ! filesink location=VGA_jpeg_file01.jpg
i got empty jpeg file with 0 byte written in root with following message

hi Morteza.. Thankyou for reply
and i tested the Gstreamer decoder working .. But i using camera option not component/composite option in bootarg setting
i got empty jpeg file with 0 byte written with following message
I am sorry I forgot to ask you two questions first:
1- What is your input card? 2-What is your output line?
My responses up to now where based on Composite input and Composite output.
For your camera card, just remove the "input-src=composite" from the pipeline and give it a try.
You can also try the following pipelines to see if your camera is working properly or not (I assume you have your composite output connected to a TV)?
Video preview without the Pitch settings:
gst-launch -e v4l2src always-copy=FALSE ! 'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480' ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite sync=false
Simplest Video test:
gst-launch -e v4l2src always-copy=FALSE ! autovideosink
I do not have a Camera card and can not test them, but I think they must work.
i used this Boot parameter
setenv bootargs console=ttyS0,115200n8 rw dm365_imp.oper_mode=0 video=davincifb:vid0=OFF:vid1=OFF:osd0=480x272x16,4050K mem=60MB vpfe_capture.interface=1davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=480x372 root=/dev/nfs nfsroot=192.168.1.106:/home/jackal/targetfs ip=dhcp
with Camera input not composite/Component input with this setting i got the output message above i posted last time..
So i Changed the following thing
mt9p031.c file. In the mt9p031_querystd function, change:
*id = V4L2_STD_MT9P031_STD_ALL;
to:
*id = V4L2_STD_720P_60;
after i changed this i got the Jpeg Image file in my Root file system but that image look like above.. the color is missing
i used following command
gst-launch -e v4l2src always-copy=false num-buffers=1 input-src=camera ! video/x-raw-yuv,format=\(fourcc\)UYVY, width=640, height=480 ! jpegenc -e ! filesink location=VGA_jpeg_file03.jpg
i do not use the Composite/Component Input ... I using only Imager interface input LI-5M02 Camera header board with MT9P031 aptina sensor
i got jpeg image only after i change mt9p031.c file camera id.... without this i can't get the output image...
Thankyou!!
Natarajan,
Did you manage to solve the problem or color is still missing?
hi.. Morteza
please help me i dn't know how to solve this color problem...
i got this image
if i run the video loop back command
./video_loopback_dm368.x470MV -O component -I camera -y5 it's working fine...
component output working good...then if run my jpeg command i got only this gray color image all the time
anything i am missing?
fhello svnatraj，
My DM368 EVM is bought from TI,Linux:206.32.17,DVSDK:dvsdk_dm368_4_02_00_06
I have also build the NFS,and i want to capture image from the camera.
uboot like this:
bootargs=console=ttyS0,115200n8 rw dm365_imp.oper_mode=0 video=davincifb:vid0=OFF:vid1=OFF:osd0=480x272x16,4050K mem=60MB vpfe_capture.interface=1 davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=480x272 root=/dev/nfs nfsroot=10.22.74.211:/root/targetfs ip=10.22.74.212:10.22.74.211:10.22.74.211:255.255.255.192
i have change the mt9p031.c,
*id= *id = V4L2_STD_720P_60;
And i execute this command :
The Jpeg file is empty,and display the error like this :
mt9p031 1-005d: control id -2147483648 not supportedvpfe-capture vpfe-capture: input information not found for the subdevmt9p031 1-005d: control id 9963776 not supportedmt9p031 1-005d: control id 9963777 not supportedmt9p031 1-005d: control id 9963778 not supportedmt9p031 1-005d: control id 9963779 not supportedmt9p031 1-005d: control id 9963780 not supported
after the above,you must use Ctrl+c to stop the processing.
Thank you in advance,please help me ...
