with the following commands I'm able to send and receive the video stream on my kubuntu PC (stream h264 via eth)

When I plug the camera into MX53 QSB I have the following report

it seems to me (based on command 1 and 2) that the video acquisition format has been accepted by the camera/gstream but it's not accepted by the vpu encoder, may you confirm?

Moreover, the following commands are able to stream something to ethernet, but due to the lack of rtp pipe I don't think there is a way to play the stream back eg from an external PC

gst-launch v4l2src ! udpsink host=192.168.1.201 auto-multicast=true port=5000 sync=false

Do you have suggestions?

Thanks,

[fabio_estevam]

Stefano,

Can you validate the Gstreamer pipelines first on a Linux PC connected to a webcam and then you stream the video to this same PC?

Regards,

Fabio Estevam

[stefanotabanell]

Fabio,

it's what I did by the commands listed above (I report them here), PC running kubuntu 12.04, the video is correctòy sent and received and visualized:

server

gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv,width=640,height=480,framerate=30/1' ! x264enc ! video/x-h264 ! rtph264pay pt=96 ! udpsink host=192.168.1.201 port=11111 sync=false

client

gst-launch udpsrc multicast-iface=eth0 multicast-group=192.168.1.201 port=11111 ! application/x-rtp,payload=96 ! rtph264depay ! decodebin ! xvimagesink sync=false

[daiane_angolini]

I'm not sure if I understand. Let me double check some infos:

* you camera will give video with raw format.

* v4l2src device=/dev/video is not an error. You can really see /dev/video into your rootfs.

it seems to me (based on command 1 and 2) that the video acquisition format has been accepted by the camera/gstream but it's not accepted by the vpu encoder, may you confirm?

I think you're right. VPU encoder will accept *some* raw format. I cannot remember it by heart, can you, please, share return of gst-inspect mfw_vpuencoder?

Moreover, the following commands are able to stream something to ethernet, but due to the lack of rtp pipe I don't think there is a way to play the stream back eg from an external PC

It's due to gstreamer version/plugins installed into your rootfs. You can upgrade your gstreamer and see if there is any package missing. I remember I was able to perform both ways streaming.

In addition, try to not use ffmpegcolorspace, it's completely executed by software/cpu

Does your camera can give any of this?

Maybe, would be better take MJPEG from your camera and stream it.

Please, let me know what you think.

[stefanotabanell]

Hi Daiane,

the format outputs are bayer,s920 or jpeg.

I've tried also the jpeg output but I think it's intended for still pictures, not video.

I would need to convert one pixel format to another accepted by the mfw_vpuencoder, OR a way to stream out the raw data (udp) without compression, in this case I would also need to use an rtp pipe to add time/frame info, otherwise I'll not be able to play the flow back on a PC, do you have suggestions to implement my points?

Thanks,

Stefano

[daiane_angolini]

At least upgrade your gstreamer version (have you already worked for it?)

For the color space conversion, I have never been able to to have a good command line using not accelerated conversion mainly because I haven´t worked hard with it.
