| - | ====== Video Streaming ====== | ||
| - | Currently testing the following stream to local Janus: | ||
| - | |||
| - | <code> | ||
| - | gst-launch-1.0 rpicamsrc preview=false ! video/x-raw,width=1024,height=768 ! x264enc speed-preset=ultrafast | ||
| - | tune=zerolatency byte-stream=true bitrate=5000 threads=1 ! h264parse config-interval=1 ! rtph264pay ! | ||
| - | udpsink host=127.0.0.1 port=8004 | ||
| - | </code> | ||
| - | |||
| - | This one is nice | ||
| - | <code> | ||
| - | gst-launch-1.0 rpicamsrc preview=false vflip=true ! x264enc tune=zerolatency speed-preset=ultrafast | ||
| - | qp-min=18 pass=5 quantizer=21 ! video/x-h264,width=640,height=480,framerate=30/1 ! rtph264pay ! udpsink | ||
| - | host=127.0.0.1 port=8004 sync=false | ||
| - | </code> | ||
| - | |||
| - | And with synced audio: | ||
| - | <code> | ||
| - | gst-launch-1.0 pulsesrc ! queue ! opusenc ! rtpopuspay ! udpsink host=127.0.0.1 port=8003 rpicamsrc | ||
| - | preview=false vflip=true ! x264enc tune=zerolatency speed-preset=ultrafast qp-min=18 pass=5 quantizer=21 ! | ||
| - | video/x-h264,width=640,height=480,framerate=30/1 ! rtph264pay ! udpsink host=127.0.0.1 port=8004 sync=false | ||
| - | </code> | ||
| - | |||
| - | Lower the CPU Usage | ||
| - | <code> | ||
| - | gst-launch-1.0 pulsesrc ! queue ! opusenc ! rtpopuspay ! udpsink host=127.0.0.1 port=8003 rpicamsrc | ||
| - | preview=false ! x264enc tune=fastdecode speed-preset=1 pass=5 quantizer=30 ! video/x- | ||
| - | h264,width=640,height=480,framerate=30/1 ! rtph264pay ! udpsink host=127.0.0.1 port=8004 sync=false | ||
| - | </code> | ||
| - | |||
| - | Using JANUS Gateway's streaming plugin configured as such: | ||
| - | <code> | ||
| - | [h264-sample] | ||
| - | type = rtp | ||
| - | id = 10 | ||
| - | description = H.264 live stream coming from gstreamer | ||
| - | audio = yes | ||
| - | video = yes | ||
| - | videoport = 8004 | ||
| - | audioport = 8003 | ||
| - | audiopt = 111 | ||
| - | audiortpmap = opus/48000/2 | ||
| - | videopt = 126 | ||
| - | videortpmap = H264/90000 | ||
| - | videofmtp = profile-level-id=42e01f\;packetization-mode=1 | ||
| - | </code> | ||
| - | |||
| - | Auto start pulse audio on Raspbian - **/etc/systemd/system/pulseaudio.service** | ||
| - | <code> | ||
| - | [Unit] | ||
| - | Description=PulseAudio system server | ||
| - | |||
| - | [Service] | ||
| - | Type=simple | ||
| - | ExecStart=/usr/bin/pulseaudio --system --realtime --log-target=journal | ||
