Hello Experts,

I have video only streaming through RTSP and no audio file is there. Is there any specific option that shall be given to GStreamer options to make the whole decoding/accelerator works faster ?

Plugin decodebin should be able to manage various encodings, but I cannot reliabily use it with nvv4l2h264 encoded stream.

 gst-launch-1.0 -ev  rtspsrc location=rtsp://127.0.0.1:8554/test ! decodebin ! nvvidconv ! xvimagesink

If you want to be sure using HW decoder, on Jetson you may try this for reading H264 encoded stream and display:

gst-launch-1.0 -ev  rtspsrc location=rtsp://127.0.0.1:8554/test ! rtph264depay ! h264parse ! omxh264dec ! nvvidconv ! xvimagesink

For H265 you would just replace replace h264 with h265.

How are you building your pipeline?

Hi @icornejo.a,

My IP camera doesn’t have voice (mic) but encoded as H.264/5 format. I want only to process video. In that case, do I need to use queue ?? Is that only Decode video buffer is enough ?
