gstreamer command Issue.

Hi All,

I am using a plugin pylonsrc (https://github.com/zingmars/gst-pylonsrc).
Below is the command I am running, it is failing. Can you please tell me wha is the issue in the command. I want to generate rtsp stream from camera. This is a USB camera.

Re: gstreamer command Issue.

hi,
1. you are working on a unmaintained git. it has move to gst-plugins-vision
2. there is no udpsink in your pipeline end
! udpsink host=127.0.0.1 port=5000
3. start with a videotestsrc, check its working, then move to camera.

Re: gstreamer command Issue.

note, GRAY8 is not supported in x264 (or RTP in general)
so videoconvert will adapt it to another (RGBA), rtp/x264 compatible format.
this might bite you if you plan to manipulate the GRAY8, as GRAY8, upstream.

see
gst-launch-1.0 -v videotestsrc !
"video/x-raw,format=GRAY8,width=1280,height=720" ! videoflip
method=vertical-flip ! identity silent=0 ! videoconvert ! identity
silent=0 ! msdkh264enc ! identity silent=0 ! rtph264pay name=pay0
pt=96 ! udpsink -v

#from "camera"
identity0: last-message = chain ******* (identity0:sink) (921600 bytes, ...
#into decoder
identity1: last-message = chain ******* (identity1:sink) (3768320 bytes, ...
#after compression
identity2: last-message = chain ******* (identity2:sink) (8389 bytes...

Re: gstreamer command Issue.

Thanks Yair!

Below is the command working fine

# gst-launch-1.0 pylonsrc ! "video/x-raw, format=GRAY8, width=1280, height=720" ! identity silent=0 ! videoconvert ! autovideosink

My goal is to run this command inside rtsp media server test-launch binary as I want to stream it on a webpage. But when I run this I am getting the following error while playing it in vlc player.

# ./test-launch "( gst-launch-1.0 pylonsrc ! video/x-raw, format=GRAY8, width=1280, height=720 ! identity silent=0 ! videoconvert ! identity silent=0 ! x264enc ! identity silent=0 ! rtph264pay name=pay0 pt=96 )"

stream ready at rtsp://127.0.0.1:8554/test

-------- When I try to play the stream (rtsp://127.0.0.1:8554/test) in vlc Below error happens ---------

x264 [error]: baseline profile doesn't support 4:4:4

Thanks,

Issac

# ./test-launch "( gst-launch-1.0 pylonsrc ! video/x-raw, format=GRAY8, width=1280, height=720 ! identity silent=0 ! videoconvert ! identity silent=0 ! x264enc ! identity silent=0 ! rtph264pay name=pay0 pt=96 )"

stream ready at rtsp://127.0.0.1:8554/test

-------- When I try to play the stream (rtsp://127.0.0.1:8554/test) in vlc Below error happens ---------

x264 [error]: baseline profile doesn't support 4:4:4

this might bite you if you plan to manipulate the GRAY8, as GRAY8, upstream.

Thanks Yair!

Below is the command working fine

# gst-launch-1.0 pylonsrc ! "video/x-raw, format=GRAY8, width=1280, height=720" ! identity silent=0 ! videoconvert ! autovideosink

My goal is to run this command inside rtsp media server test-launch binary as I want to stream it on a webpage. But when I run this I am getting the following error while playing it in vlc player.

# ./test-launch "( gst-launch-1.0 pylonsrc ! video/x-raw, format=GRAY8, width=1280, height=720 ! identity silent=0 ! videoconvert ! identity silent=0 ! x264enc ! identity silent=0 ! rtph264pay name=pay0 pt=96 )"

stream ready at rtsp://127.0.0.1:8554/test

-------- When I try to play the stream (rtsp://127.0.0.1:8554/test) in vlc Below error happens ---------

x264 [error]: baseline profile doesn't support 4:4:4

this might bite you if you plan to manipulate the GRAY8, as GRAY8, upstream.

Re: gstreamer command Issue.

hi issac, what is behind "test-launch" ?
not familiar with this ...

also consider adding a ! queue ! element before he encode step.

a good debug step is to output as a DOT file and observe it.

Below is the command working fine

# gst-launch-1.0 pylonsrc ! "video/x-raw, format=GRAY8, width=1280, height=720" ! identity silent=0 ! videoconvert ! autovideosink

Just a note that right now pylonsrc doesn't use anything other than the format from caps negotiation, so just use "video/x-raw,format=GRAY8" if you want to force it, or drop it altogether to auto negotiate. I thought of adding negotiation of width and height, but then do we center, crop, scale, etc.

Boolean. Default: false
do-timestamp : Apply current stream time to buffers
flags: readable, writable
Boolean. Default: true
camera : (Number) Camera ID as defined by Basler's API. If only one camera is connected this parameter will be ignored and the lone camera will be used. If there are multiple cameras and this parameter isn't defined, the plugin will output a list of available cameras and their IDs. Note that if there are multiple cameras available to the API and the camera parameter isn't defined then this plugin will not run.
flags: readable, writable
Integer. Range: 0 - 100 Default: 9999
height : (Pixels) The height of the picture. Note that the camera will remember this setting, and will use values from the previous runs if you relaunch without specifying this parameter. Reconnect the camera or use the reset parameter to reset.
flags: readable, writable
Integer. Range: 0 - 10000 Default: 0
width : (Pixels) The width of the picture. Note that the camera will remember this setting, and will use values from the previous runs if you relaunch without specifying this parameter. Reconnect the camera or use the reset parameter to reset.
flags: readable, writable
Integer. Range: 0 - 10000 Default: 0
binningh : (Pixels) The number of pixels to be binned in horizontal direction. Note that the camera will remember this setting, and will use values from the previous runs if you relaunch without specifying this parameter. Reconnect the camera or use the reset parameter to reset.

Integer. Range: 1 - 6 Default: 1
binningv : (Pixels) The number of pixels to be binned in vertical direction. Note that the camera will remember this setting, and will use values from the previous runs if you relaunch without specifying this parameter. Reconnect the camera or use the reset parameter to reset.
flags: readable, writable
Integer. Range: 1 - 6 Default: 1
limitbandwidth : (true/false) Bandwidth limit mode. Disabling this will potentially allow the camera to reach higher frames per second, but can potentially damage your camera. Use with caution. Running the plugin without specifying this parameter will reset the value stored on the camera to `true`.
flags: readable, writable
Boolean. Default: true
maxbandwidth : (Bytes per second) This property sets the maximum bandwidth the camera can use. The camera will only use as much as it needs for the specified resolution and framerate. This setting will have no effect if limitbandwidth is set to off. Note that the camera will remember this setting, and will use values from the previous runs if you relaunch without specifying this parameter. Reconnect the camera or use the reset parameter to reset.

Boolean. Default: false
fps : (Frames per second) Sets the framerate of the video coming from the camera. Setting the value too high might cause the plugin to crash. Note that if your pipeline proves to be too much for your computer then the resulting video won't be in the resolution you set. Setting this parameter will set acquisitionframerateenable to true. The value of this parameter will be saved to the camera, but it will have no effect unless either this or the acquisitionframerateenable parameters are set. Reconnect the camera or use the reset parameter to reset.
flags: readable, writable
Double. Range: 0 - 1024 Default: 0
lightsource : (off, 2800k, 5000k, 6500k) Changes the colour balance settings to ones defined by presests. Just pick one that's closest to your environment's lighting. Running the plugin without specifying this parameter will reset the value stored on the camera to "5000k"

I don’t have any Basler cameras. Do you need to set the output type by using another pylon command before starting the test-launch. Perhaps its default output is not 1280 x 1080. I see you have removed the framerate, what is the output of gst-inspect-1.0 for pylonsrc?

Thanks Yair!

Below is the command working fine

# gst-launch-1.0 pylonsrc ! "video/x-raw, format=GRAY8, width=1280, height=720" ! identity silent=0 ! videoconvert ! autovideosink

My goal is to run this command inside rtsp media server test-launch binary as I want to stream it on a webpage. But when I run this I am getting the following error while playing it in vlc player.

# ./test-launch "( gst-launch-1.0 pylonsrc ! video/x-raw, format=GRAY8, width=1280, height=720 ! identity silent=0 ! videoconvert ! identity silent=0 ! x264enc ! identity silent=0 ! rtph264pay name=pay0 pt=96 )"

note, GRAY8 is not supported in x264 (or RTP in general)
so videoconvert will adapt it to another (RGBA), rtp/x264 compatible format.
this might bite you if you plan to manipulate the GRAY8, as GRAY8, upstream.

Hi Yair,

I just came to know while doing googling ...this allows more logs to be printed on screen.

Thanks,

hi issac, what is behind "test-launch" ?
not familiar with this ...

also consider adding a ! queue ! element before he encode step.

a good debug step is to output as a DOT file and observe it.

Hi experts,

I ran the command with debug level 5. As the log file size is huge (38MB) I am only pasting the errors messages

Just a note that right now pylonsrc doesn't use anything other than the format from caps negotiation, so just use "video/x-raw,format=GRAY8" if you want to force it, or drop it altogether to auto negotiate. I thought of adding negotiation of width and height, but then do we center, crop, scale, etc.

Re: gstreamer command Issue.

Try to force the caps out of the camera using caps filter, remove the flip and makes this as lean as possible

You can debug less eith

Gst_debug=pylo*:5

See the transform_to warning
