I am trying to infer on a mjpeg stream from mobotix camera (rtsp://127.0.0.1:34180/stream0/mobotix.mjpeg) using deepstream-test5 application. However, the application is not starting and failing with

indent preformatted text by 4 spaces
** INFO: <bus_callback:161>: Pipeline ready

ERROR from src_elem0: Internal data stream error.

** INFO: <reset_source_pipeline:909>: Resetting source 0

ERROR from src_elem0: Internal data stream error.

** INFO: <reset_source_pipeline:909>: Resetting source 0

ERROR from src_elem0: Internal data stream error.

Does deepstream -test5 does not support this. How should I progress.

The test5 sample is based on hardware video decoder nvv4l2decoder(https://docs.nvidia.com/metropolis/deepstream/dev-guide/index.html#page/DeepStream%20Plugins%20Development%20Guide/deepstream_plugin_details.html#wwpID0E0JR0HA) which only supports h264 or h265 video decoding with rtsp streaming.

If you want to support mjpeg video, please modify the codes of function cb_rtspsrc_select_stream() in /opt/nvidia/deepstream/deepstream-5.0/sources/app/apps-common/src/deepstream_cource_bin.c to support mjpeg depay, mjpeg parse and decode with nvv4l2decoder. Please don’t forget when using nvv4l2decoder to decode mjpeg video, you need to set the “mjpeg” property as 1.

Hi Fiona.Chen,

Thanks for the reply. The pipeline worked, however, I observe a big leak while running the application.

I then played a simple pipeline

 gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:34180/stream0/mobotix.mjpeg ! rtpjpegdepay ! nvjpegdec ! fakesink

On adding nvjpegdec I observe the same leak. This is causing a big issue for me in the application. How do I solve this? Thanks.

Can you try “nvv4l2decoder” instead of “nvjpegdec”? Like “gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:34180/stream0/mobotix.mjpeg ! rtpjpegdepay ! nvv4l2decoder ! fakesink”

Thanks, it worked.

hi i am beginner with deepstream and kind of lost with it. so i was trying to modify deepstream_source_bin.c file to support mjpeg streaming and i have no clue where i could set “mjpeg” property as 1 as you said .
