Hello，everyone：
I decoded rtsp stream from IP camera with gstreamer-1.0,but meet some errors.
System environments：Ubuntu16.04、GTX1060、gstreamer-1.8.3、cuda-9.2
First，I just the below code:

sudo rm -rf ~/.cache/gstreamer-1.0/registry.x86_64.bin

Second,

gst-launch-1.0 --gst-debug=4 -v rtspsrc location="rtsp://admin:admin12345@192.168.0.64:554/Streaming/Channels/101?transportmode=unicast&profile=Profile_1 protocols=tcp latency=0" ! rtph264depay ! h264parse ! nvdec_h264 ! nvinfer ! 'video/x-raw(memory:NVMM),format=(string)NV12' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=(string)RGBA,width=(int)1920, height=(int)1080,fFramerate=30/1' ! nvosd ! nveglglessink

Some errors happened.

How to slove this problem? Thanks for you in advance!

Hi,

  1. Do you have an option of trying to decode the bitstream using the samples released in video codec SDK without bringing the gstreamer in to picture?
  2. In the log it seems there is no issue in cuvidxxx related functions. Please point to specific failures related to cuvidxxx exposed in Video Codec SDK?

Thanks,
Ryan Park

Hi,rypark
I directly decode rtsp stream using below code.

gst-launch-1.0 rtspsrc location="rtsp://admin:admin12345@192.168.0.64:554/Streaming/Channels/101?transportmode=unicast&profile=Profile_1 protocols=tcp latency=0" ! rtph264depay ! h264parse ! nvdec_h264 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=(string)NV12' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=(string)RGBA,width=(int)1920, height=(int)1080,fFramerate=30/1' ! nvosd ! nveglglessink

Worked well!

Then, I changed this file deepstream_test1_app.c in Deepstream2.0(/xx/DeepStream_Release/sources/apps/deepstream-test1/deepstream_test1_app.c), and test Deepstream samples with this code.

The below code is deepstream_test1_app.c.
