• NVIDIA GPU Driver Version (valid for GPU only) - 10.2
• Issue Type( questions, new requirements, bugs)
Error: gst-stream-error-quark: Could not multiplex stream. (10): gstqtmux.c(4561): gst_qt_mux_add_buffer (): /GstPipeline:pipeline0/GstSplitMuxSink:recording-sink2/GstMP4Mux:muxer:
Buffer has no PTS.
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)
I need solve the above error without changing muxer to matroskamux

Please help me dump stream to reproduce this issue.
It may be related to your stream.

It would be better if you provide sample code or a command line


sample code. (23.1 KB)

Due to lack of same stream,I did not run your code successfully.

But I try to build the same pipeline using the command line,It’s normal.

This is my command line


gst-launch-1.0 -e nvstreammux name=mux batch-size=1 width=1920 height=1080 ! nvinfer config-file-path=/opt/nvidia/deepstream/deepstream/samples/configs/deepstream-app/config_infer_primary.txt batch-size=1  ! nvstreamdemux name=demux uridecodebin uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h264.mp4 ! mux.sink_0 demux.src_0 ! queue ! nvvideoconvert ! "video/x-raw(memory:NVMM),format=NV12" ! nvv4l2h264enc ! h264parse ! splitmuxsink location=split_out.mp4

so I think this issue is related to your stream.

Can you dump the rtp stream to local file for me reproduce this issue ?


how to dump the rtp stream to local file?

Such as

gst-launch-1.0 urisourcebin uri=rtsp:// ! queue ! parsebin ! queue ! h264parse ! mpegtsmux ! filesink location=rtsp.ts

One more things, export GST_DEBUG=3,then run your python code give log for me ?

Maybe you can try the cmd replace with your uri first to make sure the pipeline work fine on your environment
