I probably can instruct Gstreamer to (re)encode video in an appropriate
format

I tested several profile names according to what i read in
/usr/share/gupnp-dlna-2.0/dlna-profiles/*.xml (without a clear
understanding of what does those profiles refers to ;( )

webcam-dlnaprofile=MPEG_TS_SD_EU_ISO
webcam-dlnaprofile=MPEG_TS_SD_NA_ISO
webcam-dlnaprofile=MPEG_TS_HD_NA_ISO
webcam-dlnaprofile=MPEG1
webcam-dlnaprofile=MPEG_PS_PAL
webcam-dlnaprofile=MPEG_PS_NTSC

unfortunately without success (not a big surprise ;) )


I get this error message:
(rygel:14797): MediaEngine-GStreamer-CRITICAL **: 16:59:42.042: Error

(): /GstPipeline:RygelGstDataSource/GstBin:bin1/GstV4l2Src:v4l2src1:
streaming stopped, reason not-negotiated (-4)

Does this means that gstreamer is expecting some kind of "negotiation"
from the TV? or Rygel?
