I would like to thank Wim and Remy for their work on this.
Now all it needs is some bright programmer to either put together a zip file containing everything necessary to run video streaming or explain in simple language what we need to do. That way I might be able to do video conferencing without having to fire up Zoom on one of my Linux boxes.
You already can give it some try changing ffmpeg output to an url. On the other side, use ffplay to show the video (use ffplay nobuffer and other tips to reduce latency)
First give a try to check hw the video is. May be you'll nee to adjust framerate according what is send by your webcam. Start using 25 and if the video is like an accelerated video, reduce it to 15.
ffmpeg -async 1 -framerate 15 -itsoffset 2.0 -f mjpeg -i \PIPE\Webcam\Video -thread_queue_size 96 -i \PIPE\Webcam\Audio -q:v 3 -b:a 192k zmovie.avi
Once the video is nice, then replace it by an url which could be udp ( udp://your pc ip@:2000 ) or of other supported type. On the other side, use ffplay to read the stream or other compatible player.
Not tested (itsoffset may be adjusted etc... if only voice has to be recorded, than 22050 should be enough and may reduce kbps sent as well reducing video quality to 5 give a correct video but with less kbps):
e.g. ffmpeg -async 1 -framerate 15 -itsoffset 1.0 -f mjpeg -i \PIPE\Webcam\Video -i \PIPE\Webcam\Audio -q:v 5 -b:a 128k -ar 22050 -tune zerolatency -f mpegts udp://yourserver-ip@:2000
e.g. ffplay -fflags nobuffer -probesize 64 -analyzeduration 1 -f mpegts -i udp://yourserver-ip@:2000 -volume 60 (use headphone if on the same pc in which case yourserver-ip@ could be 127.0.0.1)
If you go through an internet box, do not forget to customize the NAT (network address translation "table" to route incoming traffic on port 2000 (in this example) to your pc @ip at port 2000 for udp traffic
To allow many end users(2 or more) to watch the live stream, start ffserver after configuring the ffserver.conf file (provided conf sample provides useful information)
