Hi All,
I used the below command to record the video from a UVC CAM, it records. But the size is too large. How to add encoding to this??
gst-launch-0.10 v4l2src device=/dev/video0 ! video/x-raw-yuv,width=352,height=288 ! avimux ! filesink location=test0.avi
Below command i used for streaming a single CAM.. it works fine... How to so streaming and recording at same time... read in the abv link should add "tee".. can someone share any documents regarding this??
gst-launch v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! mfw_isink disp-width=450 disp-height=300 axis-left=50 axis-top=100
And for $gst-launch v4l2src num-buffers=-1 ! queue ! vpuenc codec=0 ! matroskamux ! filesink location=output.mkv sync=false

hi viswa,
which multimedia codec version you are using is it 11.09 or ?

Hi Yuri,
I tried the below command...
$gst-launch v4l2src always-copy=false queue-size=16 num-buffers=900 ! queue ! capsfilter caps='video/x-raw-yuv,format=(fourcc)YUY2, width=640, height=480,framerate=30/1' ! ffmpegcolorspace ! capsfilter caps='video/x-raw-yuv,format=(fourcc)I420, width=640, height=480' ! vpuenc ! avimux! filesink location= /home/test.avi

First, please try simplified command :
$gst-launch v4l2src ! ffmpegcolorspace ! vpuenc ! avimux! filesink location= /home/test.avi
then we can insert more details in order to define what option provides the problem.
Hi Yuri,
After issuing the above command the processor doesnt respond for any command or interrupt. It hangs/freezes

In the beginning of the thread :
$ gst-launch v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! mfw_isink disp-width=450 disp-height=300 axis-left=50 axis-top=100
it is stated this works ? correct ?
Yes... the below command works fine... its streams from the CAM... until i giv ctrl+c...
$ gst-launch v4l2src device=/dev/video1 ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! mfw_isink disp-width=450 disp-height=300 axis-left=50 axis-top=100

Hi Yuri,
The below command works..
gst-launch --eos-on-shutdown v4l2src device="/dev/video1" ! video/x-raw-yuv,width=640,height=480 ! ffmpegcolorspace ! jpegenc ! avimux ! filesink location=video.avi
For a 7 second video the size is 6.3MB. I am not sure whether the Encoding technique is actually happening..
Any Suggestions?
First, the GST element " jpegenc" relates to software implementation (via ARM core instructions,
without VPU support). Obe can use the next element (mjpg - image/jpeg) : ! vpuenc codec=12 !
Next, MJPEG provides separate frames encoding, without using correlations between frames,
therefore compression ratio is not so good as - say - for H.264.
My Device Hangs/Freezes for the below command
$ gst-launch v4l2src device=/dev/video1 ! ffmpegcolorspace ! vpuenc ! matroskamux ! filesink location= /home/test.mkv

I just tried the next command
$ gst-launch v4l2src device=/dev/video0 ! ffmpegcolorspace ! vpuenc ! matroskamux ! filesink location= /home/test.mkv
under the following environment :
- SDP board ;
- Linux L3_0_35_4_1_0 ;
- IMX_MMCODEC_3.0.35_4.1.0 codec package.
And the issue is not reprodusible.
What is different in Your system ?
I guess it is as same as your configuration.

1) how to set camera resolution:
You can see gst-inspect v4lsrc and look for the resolution parameters
Don´t forget to use the same for mux and encoder
2)
