Sundtek MediaTV Pro (Europe) / recording (analog) tv on synology
« am: April 07, 2013, 11:20:05 Nachmittag »
Hi,

I'm trying to record tv using my MediaTV Pro device connected to my Synology DS212j.  I'm currently trying to record analog tv on the NAS, but it doesn't seem to work.

# /opt/bin/mediaclient --start
# /opt/bin/mediaclient -e

What am I doing wrong? Has it anything to do with missing ffmpeg plugins (http://sundtek.de/support/buildffmpeg.sh)?  If so, how do I install those on my NAS, since that script needs git (and probably gcc?) to build these plugins?

My next job is to record digital tv (dvb-t and -c) using the command line on the NAS.  Would command would I then need to use?  I suppose I can't use "cat" in that case?  (I want to avoid using tvheadend, since it keeps the TV-stick from sleeping (and it's running quite hot, probably reducing its working life), switching between the modes (analog, dvb-t and -c) requires restarting tvheadend, and I guess tvheadend is quite demanding for my NAS.)
