Using CPU
- This pipeline generates a video test pattern, applies PTZ transformations, and resizes the output video to 1280x720 pixels for display.
gst-launch-1.0 videotestsrc pattern=0 ! "video/x-raw,width=1920,height=1080" ! rrpanoramaptz zoom=2.1 ! "video/x-raw,width=1920,height=1080" ! queue ! videoconvert ! autovideosink
- This pipeline reads an image, applies a zoom transformation, and displays the result:
gst-launch-1.0 filesrc location=sample.jpg ! jpegdec ! imagefreeze ! videoconvert ! video/x-raw,format=RGBA ! rrpanoramaptz zoom=1.5 ! videoconvert ! autovideosink
- This pipeline takes an input image, applies PTZ transformations, encodes the video using hardware, and records it to a file:
gst-launch-1.0 filesrc location=/home/nvidia/jmora/360sample2.jpg ! jpegdec ! imagefreeze ! videoconvert ! videoscale ! video/x-raw,format=RGBA ,width=1920,height=1080 ! rrpanoramaptz zoom=1.5 ! nvvidconv ! nvv4l2h264enc ! h264parse ! mpegtsmux ! filesink location=./example.ts
To decode the video:
gst-launch-1.0 filesrc location=./example.ts ! tsdemux ! h264parse ! nvv4l2decoder ! nvvidconv ! autovideosink
Using GPU
- This pipeline uses GPU memory (NVMM) for processing, encodes the video in H.264 format, and directs the output to a fakesink.
gst-launch-1.0 videotestsrc ! nvvidconv ! "video/x-raw(memory:NVMM),format=RGBA,width=1920,height=1080" ! rrpanoramaptz ! fakesink #gst-launch-1.0 videotestsrc pattern=0 ! nvvidconv !
