Error - a lot of buffers are being dropped - when running ds sdk python sample + IPcamera on nano

Hi there.

I have installed the Deep stream SDK 4.0.2 and when I run the python example it takes more than minutes to initialize and after some seconds I am seeing the below messages in the terminal and my test application is hanging.

Frame Number= 1647 Number of Objects= 0 Vehicle_count= 0 Person_count= 0
Warning: gst-core-error-quark: A lot of buffers are being dropped. (13): gstbasesink.c(2902): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstEglGlesSink:nvvideo-renderer:
There may be a timestamping problem, or this computer is too slow.

Highly appreciated your help.

Me too, i got the same error

Hi,

For information, please share which test app you run and hit the issue.

I run the deepstream-test3 with the RTSP Camera
At the first time, streaming run well, but after a sec, streaming got an error as shown

WARNING: gst-core-error-quark: A lot of buffers are being dropped. (13): gstbasesink.c(2902):

gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstEglGlesSink:nvvideo-renderer

and then i search it, and i found this link

Pipeline unable to perform at real time

I dont get it

Thanks for your reply.

I am using deepstream-test3 with the RTSP Camera.

yesterday I was trying with MP4 file and it was fine.

but when it comes to RTSP after a minute we are getting the above error and app almost hang stage then we need to kill the exe in task manager.

kind Note:
there is a TYPO error in deepstream-test3 python sample code like below

MUXER_OUTPUT_WIDTH=1920
MUXER_OUTPUT_HEIGHT=80 //should be 1080

Hi,
Please apply the modification to deepstream_test_3.py and try again.
1 set ‘live-source=1’ to streammux

streammux.set_property('live-source', 1)

2 Replace nveglglesink with nvoverlaysink and set ‘sync=0’

- transform=Gst.ElementFactory.make("nvegltransform", "nvegl-transform")
+ transform=Gst.ElementFactory.make("queue", "queue")
- sink = Gst.ElementFactory.make("nveglglessink", "nvvideo-renderer")
+ sink = Gst.ElementFactory.make("nvoverlaysink", "nvvideo-renderer")
+ sink.set_property('sync', 0)

3 Apply the setting of Nano to config file

Thank you Mr. DaneLLL for your respone,

I’ve tried the code, and i got a new problem here, the program running well without error, but stream video didn’t show.

These “nvoverlaysink” hide the streaming.

Hi,
Probably nvoverlaysink hasn’t been ported yet. Please keep nveglglessink and set sync=0
