Hi,
I am trying to run the sample pipeline command for single stream as mentioned in Gst-nvdsvideotemplate — DeepStream 6.2 Release documentation (nvidia.com).
However, I observed that “libcustom_impl.so” is not present in my Nvidia DeepStream docker. Am I supposed to bring/install it from somewhere else?
I did find the lib/libcustom_videoimpl.so. However, even though using the same does runs the Gstreamer command, the output video does not show up.
I have the following questions -
How to correctly run the nvdsvideotemplate plug-in and which .so to use?
How to determine what each .so actually does?
Is there a way to see the .cpp file from which each .so file is built? I want to create my own .so and thus want to see how I can write the code.
Thanks for providing the link. However, I don’t see the use of a Gstreamer command to run the pipeline. I also don’t see the creation/use of any .so file here. Can you please suggest any examples where those are used?
It’s just a demo to teach you how to use the Nvdsvideotemplate. The .so needs to be implemented based on your own functionality. In this demo, the .so is libnvds_gazeinfer.so.
I tried a simpler command. I tried using the following command -
gst-launch-1.0 filesrc location=./samples/streams/sample_720p.264 ! h264parse ! nvv4l2decoder ! nvdsvideotemplate customlib-name=“./lib/libcustom_videoimpl.so” customlib-props=“scale-factor:0.5.0” ! nvvideoconvert ! nvv4l2h264enc ! h264parse ! mp4mux ! filesink location=./result.mp4
And this worked. However, if I use the sample video sample_1080p_h264.mp4, the video fails with the error unsupported format.
Does that mean this plugin is not supported for 1080p videos? Or is this particular custom plugin (/lib/libcustom_videoimpl.so) not supported for 1080p?
There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
If you use mp4 file, you need to change the pipeline like: gst-launch-1.0 filesrc location=xxx ! qtdemux ! h264parse ! nvv4l2decoder........
