Hi,
Im trying to convert a gstreamer pipeline that works to send a video stream from a jetson tx2 to a reciever (laptop using osx via SSH) and been running into several headaches. I feel like using Gst.launch() is the easiest way to do this however ive hit on a brick wall
My original (working) pipelines are....
client_ip =<my_laptop_ip address)
sender
gst-launch-1.0 nvcamerasrc fpsRange="30 30" intent=3 ! nvvidconv flip-method=6 ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1' ! omxh264enc control-rate=2 bitrate=4000000 ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264pay mtu=1400 ! udpsink host=$CLIENT_IP port=5000 sync=false async=false
reciever
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! h264parse ! queue ! avdec_h264 ! autovideosink sync=false async=false -e
in python...
import gi
gi.require_version("Gst", "1.0")
from gi.repository import Gst
Gst.init(None)
CLIENT_IP="192.168.0.2"
pipeline = Gst.parse_launch("""nvcamerasrc fpsRange="30 30" intent=3 ! nvvidconv flip-method=6 ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1' ! omxh264enc control-rate=2 bitrate=4000000 ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264pay mtu=1400 ! udpsink host=$CLIENT_IP port=5000 sync=false async=false""")
at which point i hit....
(python:5786): GStreamer-CRITICAL **: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed
(python:5786): GStreamer-CRITICAL **: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
GLib.Error: gst_parse_error: syntax error (0)
I know this probably seems very basic however i'm new to GStreamer and i have found the documentation a bit confusing. Any help would be much appreciated
