• Hardware Platform (GPU) GPU A30
• DeepStream Version 6.4
• TensorRT Version 10.0.0.6
• NVIDIA GPU Driver Version (valid for GPU only) 535.104.12
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description) Run the deepstream_test1_rtsp_in_rtsp_out.py
No encoder compatibility for A30.
I was wondering if there is any alternative for the nvv4l2h264enc to encoder the video for the rtppay.
Can you tell us what kind of use case with video encoding you need to run on A30?
There are lots of GStreamer software encoder available. Plugins (gstreamer.freedesktop.org). You can modify the code to replace the nvv4l2h264enc with any software encoder as you like.
Thanks for the answer, my use case is an application whose input is rtsp, infer, tracker(send this meta with kafka for post analytics) and finally the output in rtsp format.
In the example, if I change the encoder with avdec_h264 from the Plugins (gstreamer.freedesktop.org) I have this error:

This is video decoder but not encoder. Why did you use this one?
Take “x264enc” as an example, a typical DeepStream inferencing and encoding pipeline could be:
gst-launch-1.0 uridecodebin uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h264.mp4 ! mux.sink_0 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 ! nvmultistreamtiler columns=1 rows=1 width=1920 height=1080 ! nvdsosd ! nvvideoconvert ! x264enc ! h264parse ! q.video_0 qtmux name=q ! filesink location=test.mp4
Sorry for the mistake, I tried a lot of encoders and I don’t know how I finally post that decoder.
nyway, I have the same error. Deepstream Version: 7.0

Have you changed the “caps” to the proper one?
Now that you mention it, I’ve tried changing it to RGBA, I don’t understand what the function of this one is either.
GST_CAPS_FEATURES_NVMM = "memory:NVMM"
# Create a caps filter
caps = Gst.ElementFactory.make("capsfilter", "filter")
caps.set_property(
"caps", Gst.Caps.from_string("video/x-raw(memory:NVMM), format=RGBA")
)

Please make sure you are familiar with GStreamer before you start with DeepStream.
x264enc is a software encoder while “video/x-raw(memory:NVMM), format=RGBA” means the Nvidia hardware buffer. Please use “gst-inspect-1.0 x264enc” to check which capabilities the encoder can accept.
Thanks, I will take a look at the documentation to know which one I should use.
Anyway changing the format does not fix the problem, now instead of having not linked I have not negotiated
# Create a caps filter
caps = Gst.ElementFactory.make("capsfilter", "filter")
caps.set_property(
"caps", Gst.Caps.from_string("video/x-raw(memory:NVMM), format=NV12")

By the way, the example by the default has I420 which is one of the formats that x264enc accepts,
The problem is not the format, it is the caps. The “video/x-raw(memory:NVMM), format=NV12” is for the Nvidia hardware buffer. You need a software buffer.
It’s finally working, deleted the “(memory:NVMM)” from the caps
