video-viewer --input-rate parameter not applied
evrdub opened this issue · comments
Hello @dusty-nv,
I am trying to implement webrtc with a jetson orin on a custom board with on-semi MIPI cameras, and it works pretty well most of the time.
The command I use is :
video-viewer csi://0 webrtc://@:8555/output --input-width=640 --input-height=360 --input-rate=15 --stun-server disabled --headlessThe other parameters are being applied correctly, but when I test I get the following result :
As you can see in the picture the command has --input-rate=15 but framesPerSecond: 48, and sometimes it varries between 30 and 60, but is never 15 FPS.
Do you know how can I apply a custom framerate ? Maybe I did not write the value correctly as expected by video-viewer ?
Thank you in advance for your help.
Hi @evrdub , when the video-viewer starts, check the console log for the gstCamera GStreamer pipeline that gets created. Then you can confirm that your --input-rate is actually being set in the pipeline:
I believe the mode needs supported by the camera though. Otherwise, your own video-viewer or video-viewer.py script and throttle the videoSource.Capture() rate with calls to sleep() or similar.
Hello, thank you for your fast reply, indeed my camera does not support the 15fps mode, I think a way of preventing this for every camera could be to use videorate in the GStreamer pipeline, for example :
videorate max_rate=15 ! video/x-raw(memory:NVMM),width=1920, height=1080,format=NV12 ! \
