Gstreamer とにかく動いたコマンドは、かたっぱしから残しておく
Gstreamer とにかく動いたコマンドは、かたっぱしから残しておく
■docker ubuntu24.04 でとりあえず動いた対面コマンド
受信側
root@03232677082a:/home/cam# gst-launch-1.0 srtsrc uri=srt://:9999 keep-listening=true ! queue ! tsdemux ! h264parse ! avdec_h264 ! videoconvert ! autovideosink
送信側
root@03232677082a:/home/cam# gst-launch-1.0 videotestsrc ! videoconvert ! x264enc ! mpegtsmux ! srtsink uri=srt://127.0.0.1:9999
■Windows10の環境でローカルループバックの環境
受信側
$ more ./srt_server.sh
#!/bin/bash
gst-launch-1.0 srtsrc uri=srt://:9999 keep-listening=true ! decodebin ! glimagesink
送信側
$ more ./srt_rtsp_client.sh
#!/bin/bash
gst-launch-1.0 rtspsrc location=rtsp://cam:Cam12345@192.168.0.11/Src/MediaInput/stream_1 latency=0 !

-max=1 ! mpegtsmux ! srtserversink uri=srt://127.0.0.1:9999 latency=500
■Gstreamerでの受信側で、送信側での巻き添えで落ちないコマンドは、その前提として、
$gst-launch-1.0 --version
gst-launch-1.0 version 1.22.0
GStreamer 1.22.0
Unknown package origin
とバージョンアップした上で、
gst-launch-1.0 srtsrc uri="srt://0.0.0.0:38089?mode=listener" keep-listening=true ! tsdemux ! h264parse ! avdec_h264 ! videoconvert ! fpsdisplaysink sync=false
で巻き添え落ちが発生しなくなった。
■bitrateを落して低品質映像を送る

■転送実験用(送信側)

mp4ファイルの繰り返し送信をするコマンドの例(ただガタガタする)
ffmpeg -stream_loop -1 -i 192.168.1.8.mp4 -vf "scale=640:360, fps=0.1" -c:v libx264 -preset ultrafast -tune zerolatency -x264-params "keyint=10:scenecut=0" -maxrate 1M -bufsize 2M -c:a copy -f mpegts "srt://192.168.1.217:38089?latency=5000000"
(今後、色々改善を試みる)
