./Server “( udpsrc name=pay0 port=5420 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" )”

When the consumer is 1fps, the encoder doesn’t work, but if you change it to x264enc, it works. I want to use nvv4l2h264enc How to do it?

consumer(1fps fail):

please refer to this command:
gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream/samples/streams//sample_720p.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! videorate ! “video/x-raw(memory:NVMM), framerate=(fraction)1/1” ! nvvideoconvert ! capsfilter caps="video/x-raw(memory:NVMM), format=“NV12"” ! nvv4l2h264enc bitrate=1000000 ! filesink location=a.h264

The pipeline you showed is no different from the pipeline I uploaded. And like the pipeline I uploaded, I want to receive it as udp and export it as udp. Is it possible with udp?

5

from my last command, nvv4l2h264enc can encode 1 fps raw data.
nvv4l2h264enc needs NV12 input, to narrow this issue , please check if can get NV12 data from udp first.

I checked and there is no problem with nvv4l2h264enc.
But rtsp-server was the problem.
rtsp-server works at 6fps, not 1-5fps.
Do you know why?

  1. please refer to this command to test fps before encoding.
    gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream/samples/streams//sample_720p.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! videorate ! “video/x-raw(memory:NVMM), framerate=(fraction)1/1” ! nvvideoconvert ! fpsdisplaysink
  2. if nvv4l2h264enc outputs data to file, please check if fps is 1. if yes, the issue should be RTSP module.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
