REg: Streaming and Recording Simultaneously

vishvapathi · ‎02-26-2014

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

No such IOCTL, cmd is 22032

Setting pipeline to PAUSED ...

try using this command

gst-launch mfw_v4lsrc fps-n=30 capture-width=640 capture-height=480 capture-mode=0 ! queue ! mfw_vpuencoder codec-type=0 ! avimux ! filesink location=shan3.avi sync=false

Hi Shan,

For i.MX6 codec prefix "mfw" is not used; elements re mnamed just as "vpudec", "vpuenc"

gst-inspect | grep imx

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

Yuri · ‎02-27-2014

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.

vishvapathi · ‎02-27-2014

Hi Yuri,

After issuing the above command the processor doesnt respond for any command or interrupt. It hangs/freezes

$ gst-launch v4l2src device=/dev/video1 ! ffmpegcolorspace ! vpuenc ! avimux! filesink location= /home/test.avi

Yuri · ‎02-27-2014

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 ?

vishvapathi · ‎02-27-2014

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?

Yuri · ‎03-05-2014

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.

vishvapathi · ‎03-06-2014

My Device Hangs/Freezes for the below command

$ gst-launch v4l2src device=/dev/video1 ! ffmpegcolorspace ! vpuenc ! matroskamux ! filesink location= /home/test.mkv

Yuri · ‎03-11-2014

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 ?

vishvapathi · ‎03-12-2014

Hi Yuri,

I have MARS board with IMX processor from Embest Technologies.
- Linux L3.0.35_4.1.0_130816

- Multi-media:IMX_MMCODEC_3.0.35_4.1.0_BUNDLE_CODA

I guess it is as same as your configuration.

daiane_angolini · ‎02-26-2014

cool

let us know

daiane_angolini · ‎02-26-2014

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)

tee

GStreamer-devel - Good example to show usage of tee
