TX1 L4T28.2 camera stream 2A is abnormal

Hi all,

We use the IMX274 sensor with TX1 L4T28.2 to capture the video stream,
and when we test in sunny day and dark environment, the video stream 2A was not good.
Did you have any idea to improve?

Our stream command with gstreamer rtsp server:
./test-launch “nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080 ! omxh264enc bitrate=2000000 ! video/x-h264, profile=baseline ! rtph264pay name=pay0 pt=96”

hello walker.hsiao,

you’re using gst pipeline to send capture frames through RTSP.
it’s by default using 1/fps exposure time; you should include exposuretimerange property to set different exposure values.

BTW,
please also refer to Multimedia API Sample Applications. check samples to uses Libargus APIs.
thanks

Hi Jerry,

Thanks for your suggestion.

We cannot find the exposuretimerange in the nvcamerasrc with L4T28.2,
Could you provide the same property in this version? (i.g.:exposure-time)
If you could help to provide the sample gstreamer pipeline is better, thank you very much.

Best Regards,
Walker

hello walker.hsiao,

you may check those element properties with gst-inspect-1.0,
for example, $ gst-inspect-1.0 nvcamerasrc

Hi Jerry,

Yes, we already do that, but we had tried to set these property, and cannot fix this problem.
May you suggest some properties setting we could try to reduce the issue?
Thanks.

hello walker.hsiao,

could you please share the gstreamer pipeline line you’re used.
thanks

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi walker.hsiao,

Is this still an issue to support?
Any result can be shared?
Thanks

Hi Kaycc and JerryChang

Sorry for late reply.

We still have no idea for this issue,
we used the gstreamer rtsp-server command to create pipeline:

./test-launch “nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=1920, height=1080 ! omxh264enc bitrate=2000000 ! video/x-h264, profile=baseline ! rtph264pay name=pay0 pt=96”

and we see the gst-inspect-1.0 nvcamerasrc information:
exposure-time : Property to adjust exposure time.
This property will have effect only when Exposure mode is Off.
flags: readable, writable
Float. Range: 0 - 3.402823e+38 Default: 0.033

we cannot use this property since we need the auto exposure feature,
Could you have any idea to fix this problem?

The critical issue is when we in dark environment, the stream view have abnormal rainbow effect, this will make our recognition feature fail.
Thanks.

it looks you’d already initial another new discussion thread, let’s moving to Topic 155117 for further supports.
