Section1: problem statement
I have a working deepstream application developed based on deepstream_test_5 in C that uses uri=file://../streamer/Vehicle.Target.Sample_EO.ts under [source0] tag in a config file.
It runs using this command:
./my-app -c configs/test_config_file_src_infer.txt
Desired next step
Now I want to configure the application to use uri=rtsp://127.0.0.1:8554/stream1 under the [source0] tag in the config file.

return Gst.parse_launch(pipeline)
class GstreamerRtspServer:
def __init__(self):
self.rtspServer = GstRtspServer.RTSPServer()
factory = TestRtspMediaFactory()
factory.set_shared(True)
mountPoints = self.rtspServer.get_mount_points()
mountPoints.add_factory("/stream1", factory)
self.rtspServer.attach(None)
if __name__ == '__main__':
s = GstreamerRtspServer()
loop.run()
running the server (rtsp_server.py):
python3 rtsp_server.py
- please note
src_demuxcan be changed to use a videotestsrc and it works for step 3!

it doesn’t run but look what happens to rtsp_server.py after I run this command. A new element is created by
rtsp_server.pyeach time I run this gstreamer command:nvidia@jetson2:/opt/nvidia/deepstream/deepstream-5.0/sources/apps/sample_apps/my-app$ python3 rtsp_server.py Element created: filesrc location=streamer/Vehicle.Target.Sample_EO.ts ! qtdemux name=demux demux.video_0 ! queue ! rtph264pay name=pay0 config-interval=1 pt=96

Questions
-
This seems quite straightforward and it works for a videotestsrc, so where may I investigate to see why it doesn’t work with a
.tsfile? -
How can I properly install
gst-validate-1.0? I installed all normal packages from the gstreamer installation page (gstreamer has been working for a while now) and also installed the.tar.xzfiles located here (https://gstreamer.freedesktop.org/) with this command:sudo tar Jxvf [package-name.tar.xz]
I cannot use gst-validate-1.0 playbin uri=file:///path/to/some/media/file it only gives this:
nvidia@jetson2:/opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/my-app/streamer$ gst-validate-1.0 Vehicle.Target.Sample_EO.ts
-bash: gst-validate-1.0: command not found
Thanks for reading and your help is much appreciated!
