Hello everyone, I’m trying to encode video I already processed using CUDA with the nvv4l2h265enc encoder using GStreamer. To do so, I need to pass it a GstBuffer that matches the filter it wants (It says it needs memory:NVMM). I am slowing picking out what that actually means. By reading the dsexa…

Hi, Could you re-flash the system through SDLManager and try again? Since we don’t observe the segment fault, probably the system is not clean and it might help to do clean re-flash. Please enable the property to get run hardware encoder in max performance: maxperf-enable : Enable or Disab…

Thank you for that sample. I am still processing it, but it’s definitely a step in the right direction. Thank you. I have one quibble. The program this is supposed to integrate with runs on a headless server. For using CUdeviceptr, this is not a problem. This program, however, calls eglGetDisplay, …

Hi @DaneLLL could you please respond ? Thanks

I also ran into another, more major, concern. gst-inspect claims that changing the bitrate is only possible when the element is in READY or NULL state. Does that mean that every time I change the bitrate (CBR mode) the encoder will issue a new IDR? Because if so, this product is unusable to us :-( T…

I know there is qp per frame to control bitrate but perhaps @DaneLLL can add to this

I do not want to try to guess the correct QP. I know how much bandwidth I have, and want the encoder to get the maximal quality out of it. I’m sorry for repeating this, but it’s something that NvEnc knows how to do. I might be able to hack something out of VBR and setting the maximal bandwidth bel…

Hi, Please refer to [image] Nvarguscamerasrc jetpack-4.3, No cameras available, nvbuf_utils: Could not get EGL display connection, requirements Jetson TX2 To be more correct, we don’t know it is nvgpu error in the beginning. That is why we asked you to check nvdisplay fi…

Hi, For changing bitrate dynamically, please refer to [image] Gstreamer variable bitrate for UDP streaming Jetson TX2 Hi, Dynamic bit rate is supported in omxh264enc. Attach a sample for your reference. For questions related to gstreamer frameworks, please go to http:/…

Hi DaneLLL, Thank you, but this is not quite what I was referring to. An encoder has two modes of operations. Constant Bit Rate, or CBR, which means that all frames receive exactly the same bitrate, and Variable Bit Rate, or VBR, in which the bitrate you set is the average bit rate for the encoding…

Hi, It may not be shown correctly in gst-launch-1.0. You can change bitrate runtime. Please check the attachment and give it a try $ g++ -Wall -std=c++11 test2.cpp -o test $(pkg-config --cflags --libs gstreamer-app-1.0) nvidia@nvidia-desktop:~$ ./test Using launch string: nvarguscamerasrc ! vide…

Hi, Thank you. The bitrate command did, indeed, work while playing. As you are no doubt surprised to hear, this uncovered a new batch of questions. Sorry about that. I can’t seem to get force-IDR to work I’ve tried the following code: GstFlowReturn ret; g_signal_emit_by_name (_e…

Hi,
Please refer to

So if you have the drivers installed, the call should succeed even though the device is headless.

eglGetDisplay(EGL_DEFAULT_DISPLAY);
