ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: Could not open resource for reading and writing. #138

I installed gstreamer-msdk several days ago. And I successfully captured stream from ip camera via rtsp with the commands:

# gst-launch-1.0 -v rtspsrc location="rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp" latency=300 ! rtph264depay ! h264parse ! mfxh264dec ! autovideosink
# gst-launch-1.0 -v rtspsrc location="rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp" latency=0 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

But now, when i run the same commands in the same machine, i get the error results:

Setting pipeline to PAUSED ...

I use Ubuntu 16.04 with kernel 4.15.0-42-generic and installed media-sdk with 2018 Q2 release. Otherwise, now i can capture stream with vlc app via rtsp:

 # cvlc "rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp"

and also can capture stream with opencv:

import cv2

cap = cv2.VideoCapture('rtsp://192.168.1.10:554/user=admin&password=&channel=1&stream=0.sdp')

while(True):
     ret, frame = cap.read()
     cv2.imshow('frame',frame)
     if cv2.waitKey(1) & 0xFF == ord('q'):
         cv2.destroyAllWindows()
         break

Except run the command with gstreamer-media-sdk. Does anyone else meet the same problem? Thanks for your reading.

Solved. Setting no proxy will be ok.

Hi, Iam facing the same error. Can you please elaborate on how you solved this error? thankyou.

7wdeepin commented 5 years ago

@Aaronreb In my case, I ran commands under proxy. When I set no proxy, errors disappeared.

$ export http_proxy=
$ export https_proxy=

Mine was solved by adding h264_ulaw.sdp in rtsp link e.g, "rtsp://ip:port/h264_ulaw.sdp"
