From MythTV Official Wiki
system still is very ungood but usable.
i started a tvpc project because i was upset with some features and failures of SRP 2410 i got before.
- however the SRP is still what i would recommend for those who want an alternative to mythtv (since setting mythtv up is a b**ch)
Contents |
environment:
- 1 satelite:Quad:digital dvb-s
- cables up to 25m
- low duty lan/wlan network: 50% offline (power saving)
- 2lcd hd-tvs with hdmi and pc inputs (of course at two different sites)
- samsung lexxc750
- toshiba xxSL733G (recommend)
the aim (simple rules for target systems):
- record all what i like
- make it cheap
- try to use less power
- no mythtv sourcecode modification(i dont want to go down that road yet)
- my folks have to be able to use it too (almost an impossible mission)
- most recently Master-to-Master recording replication network access (have no idea how to call that in fact i would only use nfs and m2m delayed replication)
the computers:
"old 2003" P4 shuttle pc new life for mythtv
- 500gb hdd
- nv gf fx5600
- 1gb ram dc
- wlan dwl-g122
- Technisat SkyStar 2 DVB-S PCI (recommend : worked PLUG AND PLAY on recent mythbuntu and is cheap , the included ir-remote/receiver is usb but not so good )
- tiny RADIO remote keyboard (cant recommend that one but generally ... have not more than 3m distance on wireless keyboards to the receiver)
- powerconsumption between 80 and 100 W
"new" one
- MSTECH MC-200 (cant recommend however it was cheap 30€ and has an ir receiver)
- H55 biostar (95% working s5 wakeup 100€ )
- core i3 including graphics ( 100€ cant recommend, ion and atom would have been better)
- tbs-6981 (divers have to be rebuild after every kernel update, dont know if there is an alternative twin available 150€ cant recommend)
- hdd 1tb (950gb XFS, 50GB ext4 )
- powerconsumption between 50 and 70 W
- logitech harmony 600 (recommend 60€)
setup and customizations
- generally an ubuntu
- mythtv ... later repository from mythbuntu
- backend and frontend on same machine for independent use
- irxevent
- remapping the MCE-remote-codes of the ir receiver
- mythtv cant distinguish between caps and non caps and certain metakey combinations
- it helps with dpms too
- xautolock -time 10 -locker script -noclose
- script
- that script should check the database
- and only if it is not running
- killall mythfrontend
- script
- DPMS for auto tv shutdown (my stupid tv says no signal at that ... however minutes later it shuts down)
- recently it appears this creates a problem with hddecoder (so i disabled it)
- harmony 600 remote
- master-A 2 master-B doubelling
- watch on master B what master A has recorded ... (if network and master A are running )
- this addresses the standalone system versus coupled system problematic ...
- still there are a few drawbacks ... since nfs was used premature loss of network can cause a problem
- i tried to add the other backend data as slave backend data but it did not succeed yet
installed Version
MythTV Version : v0.24.1-1-g347cd24 MythTV Branch : fixes/0.24 Network Protocol : 63 Library API : 0.24.20110505-1
todo
- master2master needs to be made better
- kill mythfrontend when it hangs automatically (that will involve to process the log and act on certain conditions)
- kill backend in the same way when it "hangs" (things like "all inputs are busy" while no recording is done)
- check if it is recording as planed or kill/restart it (sometimes an recording doesnt start even though its scheduled and backend is accessible )
- create a watchdog board (watch if the system is running correctly or if it is not starting when required ... later maybe display and CEC support )
- make it use S3 instead of S5 (currently the hardware and drivers dont allow s3 to be used effectively)
- remotely start the system (switch on)
- HDMI-CEC switch off after some time (this requires to tap into the hdmi cable either directly or by extender)
- creating scripts for proactive show scanning and recording based on the recording i made before (tivolike)
UFO problems: errors i dont know why exists and how to fix
- for some reason watching tv and switching chanel doesnt work, frontend hangs (didnt check the log yet)
- well apparently it had to do with a setting (BrowseAllTuners in tv-osd)
other problems and "personal wishlist"
- general tiny preview everywhere in the menue would be good (its a receiver mainly ... see commercial products)
- enable zapping (direct video feeding when channel switching)
- default audio language/track (MP2 instead of AC3)
- switch tuner when watching tv and target channel is not on that bonquet
- make menue structure configurable (completely) maybe 2 menue-structures one simple and one full
- resume interrupted recordings also if later is available (record the later too of course if possible).
