Hi Etienne, you can also make a Gstreamer pipeline that writes to a v4l2loopback since it's available in the 14.04 repos, I think it's easier than ffmpeg solution But you'll have to make a different pipeline for each like with pdgst.
btw, I just tested VLC plugin and successfully display a video stream into Gem with libvlc-dev version 2.2.0pre2 on Ubuntu 14.10 64bit + a -- do it yourself http://antoine.villeret.free.fr 2015-03-04 20:48 GMT+01:00 Olivier Baudu <[email protected]>: > Hi... > > You can use ffmpeg + v4l2loopback to make a "virual" video device openable > with gem... > > Here's an example of the command line : > ffmpeg -i rtsp://10.0.0.69:1234//live1.sdp -pix_fmt yuv420p -an -r 25 -f > v4l2 /dev/video69 > > (http and rtmp work too) > > But ffmpeg must be built with the v4l2loopback backend. > The static one here works : http://ffmpeg.gusari.org/static (unreachable > right now... :-/ ) > > Here's some documentations, but it's in french, sorry : > http://wiki.labomedia.org/index.php/Flux_TaBec > > Goodluck... > > 01ivier > > --- > "On ne peut pas vivre dans un monde où l'on croit que l'élégance exquise > du plumage de la pintade est inutile.
