The attached pipeline image is implemented combining both deepstream_test4 and deepstream_reference_apps-runtime_source_add_delete samples.
Initially, rtsp sourcebins are added to nvstreammux and removed at runtime. Once all the sources are removed from the nvstreammux it outputs following warning.
SourceBin:0 STATE NULL CHANGE SUCCESS
Released StreamMux Pad: 0x7ed755a840
WARNING from element stream-muxer: No Sources found at the input of muxer. Waiting for sources.
Warning: No Sources found at the input of muxer. Waiting for sources.
Then another source is added and the pipeline stops with the queue element returning following error.
ERROR from element tee-que1: Internal data stream error.
Error details: gstqueue.c(988): gst_queue_handle_sink_event (): /GstPipeline:main-pipeline/GstQueue:tee-que1:
streaming stopped, reason error (-5)
Returned from main loop, stopping playback
How to gracefully handle this use case without pipeline going into error state?
Simplyfied code and config files can be found inside runtime_source_add_delete.zip. It’s a modified version of the deepstream_test_rt_src_add_del.c.
Two new elements are added to the pipeline namely tee and queue,
source bin → file-source ! h264-parser ! nvh264-decoder
Rest of the pipeline → streammux ! nvinfer ! nvtracker ! tee ! queue ! nvtiler ! nvvideoconvert ! nvosd ! nveglsink
Initially one sourcebin is created and we wait until it becomes EOS. Then that sourcebin is removed from the nvstreammux. After that we try to add a new sourcebin to the nvstreammux. Then the above mentioned error is produced from the queue element.
I’ve also added the gst-debug-log of the pipeline with log level 4 enabled.
Did you run this sample inside DeepStream-6.0:devel docker container? I’m afraid the crash is due to dependency mismatch. Also can you please use this command to run.
./deepstream-test-rt-src-add-del file://$DS_SDK_ROOT/samples/streams/sample_1080p_h265.mp4
