Hi!
I’m trying to run rtsp stream from Axis camera.
If I set uri=“rtsp://log:pass@192.168.90.90:554/axis-media/media.amp” everything works fine and logs in console:

What’s wrong?

Can you fill the template with the platform and software information? It will save much time for us to know what is happenning.

Can I suppose you are using deepstream-app? If so, current deepstream-app can only support RTSP streams with h264 or h265 format video. If you want to support mjpeg format video, please refer to Deepstream test 5 not able to process mpeg rtsp stream

Hi, @Fiona.Chen! Thank you for reply!

I’ve used code depending on deepstream-test3_app.c.
I’ve tryed to copy /opt/nvidia/deepstream/deepstream-5.0/sources/app/apps-common/src/deepstream_source_bin.c to my includes directory and added to function cb_rtspsrc_select_stream() printing of encoding_name, but nothing printing to console.
I used uridecodebin and next functions:

static GstElement *
create_source_bin (guint index, const gchar * uri)
{
  GstElement *bin = NULL, *uri_decode_bin = NULL;
  gchar bin_name[16] = { };

  g_snprintf (bin_name, 15, "source-bin-%02d", index);
  /* Create a source GstBin to abstract this bin's content from the rest of the
   * pipeline */
  bin = gst_bin_new (bin_name);

  /* Source element for reading from the uri.
   * We will use decodebin and let it figure out the container format of the
   * stream and the codec and plug the appropriate demux and decode plugins. */

    /* Link the decodebin pad only if decodebin has picked nvidia
     * decoder plugin nvdec_*. We do this by checking if the pad caps contain
     * NVMM memory features. */
    if (gst_caps_features_contains (features, GST_CAPS_FEATURES_NVMM)) {
      /* Get the source bin ghost pad */
      GstPad *bin_ghost_pad = gst_element_get_static_pad (source_bin, "src");
      if (!gst_ghost_pad_set_target (GST_GHOST_PAD (bin_ghost_pad),

Can you try the following pipeline with command? Are you using Jetson board?

gst-launch-1.0 uridecodebin uri=rtsp://xxxxx ! nvvideoconvert ! nvegltransform ! nveglglessink

And I have one more problem:
In gst-example I print frame_meta->buf_pts every second, but delta of two neighborhood buf_pts is ~0.6 sec

One topic for one problem, please create new topic for new problem. Please use template to provide information when creating new topic.

I’m not sure what is the format. Can you get the pipeline graph with the pipeline you can run?
gst-launch-1.0 -e uridecodebin uri=“rtsp://xxxx/axis-media/media.amp?videocodec=jpeg” ! nvvidconv ! jpegenc ! matroskamux ! autovideosink
The method is in the " Getting pipeline graphs" part in this link https://gstreamer.freedesktop.org/documentation/tutorials/basic/debugging-tools.html?gi-language=c

Or you can refer to this link:

If the pipeline in Deepstream test 5 not able to process mpeg rtsp stream can not work in your board, there is no way to run your case with deepstream.
