Hi all,
First of all, I'm a beginner to gstreamer, but I've been enjoying using it so far!
I have a Pi Zero with a Pi camera and a mic. I'm livestreaming audio/video from the Pi to a remote server with a NGinx frontend running a Janus webRTC gateway. I'm using gstreamer from the Pi to send RTP to Janus. I am looking for < 1s latency (but does not have to be <500ms) and relatively consistent A/V quality.
My full Pi command:
gst-launch-1.0 -v rpicamsrc bitrate=500000 inline-headers=TRUE keyframe-interval=4 preview=0 ! video/x-h264,width=1280,height=720,framerate=20/1,profile=baseline ! \
h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=XXXX port=8004 \
alsasrc device=mic_mono buffer-time=1000000 ! audio/x-raw,format=S32LE,rate=22050,channels=1 ! \
audioconvert ! audioresample ! opusenc complexity=3 cbr=TRUE ! rtpopuspay ! udpsink host=XXXX port=8005
My video quality is great until there's a lot of movement in front of the camera. When this happens, the video quality drops by a lot, with every frame looking like this: http://imgur.com/a/ArPi4 Normally it looks like this: http://imgur.com/a/WAaoo
I understand UDP is unreliable and packet drops may occur. But can anyone suggest how I could optimize my settings to prevent such huge drops in video quality? Perhaps if I added a little more latency, or some other settings I can tweak?
Thanks so much!
Christina
