This wiki presents some performance measurements of a typical GstRtspSink pipeline on the NVidia TX1 EVM.
GstRtspSink Pipeline
The following GstRtspSink pipeline captures images from the IMX219 Sony sensor, encodes it using HW accelerated H264 encoder and streams it using GstRtspSink.
PORT=5000
MAPPING=/stream1
gst-launch-1.0 nvcamerasrc sensor-id=0 ! omxh264enc control-rate=2 bitrate=4000000 ! \
'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! video/x-h264, mapping=${MAPPING} ! \
perf ! rtspsink service=${PORT}
The perf element is optional and its only used to print frame rate and CPU usage. If you are interested in using it, you may find it at https://github.com/RidgeRun/gst-perf
Framerate
The frame rate was measured using the perf element.
