Error in qtmux

Accelerated Computing Intelligent Video Analytics DeepStream SDK

• Hardware Platform ( GPU): A30X
• DeepStream Version: 6.1.1
• TensorRT Version: 8.4.1.5
• NVIDIA GPU Driver Version: 515.65.01
• Issue Type: questions

I started the DeepStream docker container (nvcr.io/nvidia/deepstream: 6.1.1 -devel),
Received an h264 stream on nvdsudpsrc with Rivermax and tried to save it to mp4.
I executed the following pipeline.

gst-launch-1.0 -e nvdsudpsrc address=192.168.x.x local-iface-ip=192.168.x.x port=8500 !
application/x-rtp,media=video,encoding-name=H264 !
queue !
rtph264depay !
h264parse !
qtmux ! filesink location=./out2.mp4

However, I could not save the mp4 file correctly because of repeated errors like the following:

Additional debug info:
gstqtmux.c(4832): gst_qt_mux_add_buffer (): /GstPipeline:pipeline0/GstQTMux:qtmux0:
Buffer has no PTS.
ERROR: from element /GstPipeline:pipeline0/GstQTMux:qtmux0: Could not multiplex stream.
Additional debug info:
gstqtmux.c(4832): gst_qt_mux_add_buffer (): /GstPipeline:pipeline0/GstQTMux:qtmux0:

Do you know how to solve this problem?

The sender pipeline is:
gst-launch-1.0 -e videotestsrc !
x264enc !
rtph264pay name=pay0 pt=96 !
udpsink host=192.168.x.x port=8500 sync=false

The environment is:
Hardware Platform(GPU):A30X
docker image:nvcr.io/nvidia/deepstream:6.1.1-devel
OS:ubuntu20.04
cuda:11.7.1
GPU Driver:515.65.01
TensorRT Version:8.4.1.5
Rivermax version:1.11.11

You can add -v in the pipeline to get more debug info.

I tried same command with -v option, then I got following messages.
According to these log, could you find out the cause of qtmux error?

gst-launch-1.0 -e -v nvdsudpsrc address=192.168.0.2 local-iface-ip=192.168.0.2 port=8500 ! application/x-rtp,media=video,encoding-name=H264 ! queue ! rtph264depay ! h264parse ! qtmux ! filesink location=./out2.mp4

Seems the log is not enough, you need to dump h264parse srcpad gstbuffer timestamps, try to raise the debug level to 6, --gst-debug-level=6.

6

I raised the debug level to 6 and ran the same command. Upload the output log.
According to these log, could you find out the cause of qtmux error?
20220922_00.log (9.2 MB)

7

udpsrc did not generate PTS timestamp, it’s a pure gstreamer issue, suggest you ask the question in gstreamer community.

8

Thank you for your response.

Using udpsink and udpsrc worked fine.
Does this mean that data sent by udpsink cannot be received by nvdsudpsrc?

Does the sender have to be nvdsudpsink to receive with nvdsudpsrc?

I have been facing a very similar issue recently.
Based on my observation this happened when there is a network congestion. (Can be unrelated to your issue)
A very quick fix is to change your muxer to matroskamux.

But note this is not a solution and just a workaround. Matroskamux can help interpolate the PTS thus avoid crashing the pipeline. You may observe some grey frames in your video when the Buffer has no PTS situation happens. But your pipeline will not crash.

Or I think if you can somehow modify the PTS in the GstBuffer before it reaches the qtmux, it would work. But you’ll need to write the code instead of using the gst-launch-1.0 command.

12

sorry for the late reply, Is this still an issue to support? Thanks

13

The qtmux problem is not fixed, but it can be avoided by using matroskamux.
Thank you.
