gst-launch-1.0 -v -e filesrc location=material/talk.mp4 \
! decodebin ! videoconvert ! autovideosink

export CANDIDATE="192.168.0.106"
sudo docker run --rm --env CANDIDATE=$CANDIDATE \
  -p 1935:1935 -p 1975:8080 -p 1985:1985 -p 1995:8000/udp \
  registry.cn-hangzhou.aliyuncs.com/ossrs/srs:5 \
  objs/srs -c conf/rtmp2rtc.conf

• push local video stream from mp4 to rtmp

gst-launch-1.0 -vv filesrc location=material/talk.mp4 \
! decodebin \
! videoconvert ! identity drop-allocation=1 \
! x264enc tune=zerolatency ! flvmux streamable=true \
! rtmpsink location='rtmp://192.168.0.106:1935/live/waltertest'
