Link two gstreamer rtspsrcs

Hello everyone! I have two ip-devices (camera for video stream and coder for audio stream). I want to connect two streams and in the end receive file (and stream it to rtspclientsink in future). How can I do it? I used to try a lot of combinations of gst-elements (yes, I checked pads, they match). Camera and coder are defenitely in working condition. Please help me ^_^
Here is one of pipelines I’ve tried:
gst-launch-1.0 -e rtspsrc location=’<camera_ip>’ name=src
src. ! rtph264depay ! h264parse ! avdec_h264 ! queue ! mux.
rtspsrc location=’<coder_ip>’ ! rtpssrcdemux name=dmx
dmx.audio_0_01e2 ! aacparse ! mux.
matroskamux name=mux ! filesink location=video.mp4
and errors I’ve got:

Hi,
We suggest break down the pipeline to audio and video only and check if both video and audio sources are good first:

gst-launch-1.0 -e rtspsrc location=’<camera_ip>’ name=src src. ! rtph264depay ! h264parse ! avdec_h264 ! queue ! mux. matroskamux name=mux ! filesink location=video.mp4

gst-launch-1.0 -e rtspsrc location=’<coder_ip>’ ! rtpssrcdemux name=dmx dmx.audio_0_01e2 ! aacparse ! mux. matroskamux name=mux ! filesink location=audio.mp4

Hi! both of pipelines you gave do not work, but this one do : gst-launch-1.0 -e rtspsrc location='<cam or coder ip>' ! rtph264depay ! h264parse ! avdec_h264 ! queue ! mux. matroskamux name=mux ! filesink location=only_video.mkv
Unfortunately, it give me only video stream. Btw, I use jetson nano. Is there any workable pipeline for sound?

Hi,
Looks like audio source cannot be received and decoded. Suggest you work out a working pipeline for audio decoding first. And then combine the audio and video pipelines.
