GStreamer 使用 rstp

URI="rtsp://user:password@192.168.1.123:554/cam/realmonitor?channel=1&subtype=0"

使用 playbin

$ gst-launch-1.0 -v playbin uri=$URI

$ gst-launch-1.0 -v playbin uri=$URI uridecodebin0::source::latency=3000::video-sink=autovideosink

使用 uridecodebin

$ gst-launch-1.0 uridecodebin uri=$URI name=d d. ! nvvideoconvert ! nveglglessink

$ gst-launch-1.0 uridecodebin uri=$URI name=d d. ! nvvideoconvert ! nveglglessink d. ! queue ! audioconvert ! audioresample ! autoaudiosink

使用 decodebin

$ gst-launch-1.0 rtspsrc location=$URI ! application/x-rtp, media=video ! decodebin ! nvvideoconvert ! nveglglessink

$ gst-launch-1.0 rtspsrc location=$URI ! application/x-rtp, media=video ! decodebin name=d d. ! queue ! nvvideoconvert ! nveglglessink d. ! queue ! audioconvert ! audioresample ! autoaudiosink

自行編寫

$ gst-launch-1.0 rtspsrc location=$URI ! application/x-rtp, media=video ! queue ! rtph265depay ! h265parse ! nvv4l2decoder ! nvvideoconvert ! nveglglessink

$ gst-launch-1.0 rtspsrc location=$URI name=d d. ! application/x-rtp, media=video ! queue ! rtph265depay ! h265parse ! nvv4l2decoder ! nvvideoconvert ! nveglglessink d. ! queue ! application/x-rtp, media=audio ! rtppcmadepay ! alawdec ! autoaudiosink

存檔

$ gst-launch-1.0 -e rtspsrc location=$URI ! application/x-rtp, media=video ! queue ! rtph265depay ! h265parse ! matroskamux ! filesink location=aa.mkv

存檔並顯示

$ gst-launch-1.0 -e rtspsrc location=$URI ! application/x-rtp, media=video ! queue ! rtph265depay ! h265parse ! tee name=t  t. ! queue ! avdec_h265 ! videoconvert ! autovideosink t. ! queue ! matroskamux ! filesink location=aa.mkv

存檔並顯示(因使用 nvv4l2decoder，所以要在 h265parse 前 tee)

$ gst-launch-1.0 -e rtspsrc location=$URI ! application/x-rtp, media=video ! queue ! rtph265depay ! tee name=t  t. ! queue ! h265parse ! nvv4l2decoder ! nvvideoconvert ! nveglglessink t. ! queue ! h265parse ! matroskamux ! filesink location=aa.mkv

常用

nveglglessink nvoverlaysink autovideosink xvimagesink fakesink

nvvideoconvert videoconvert

nvv4l2decoder avdec_h265

Jetson 使用 nveglglessink 前要加 nvegltransform
