Raspberry PI Questions

[JavaWiz]

Right, I forgot about the mpeg license, you'll need that. Less than $5us done online from the rasppi site.

Most of my recording now are h264 HD and the Mpeg stuff is SD so will probably still pay for licence but not a biggy
Have ordered the B+(4 usb ports etc) and case with sd card with xbmc already loaded. Looking forward to have a play.

Video starting even on a pc is pretty slow in xbmc

[stustunz]

WOW
the raspberry PI is pretty cool
The play back of h264 files is out standing once it gets going(takes 10 seconds to start but once going its very good)
Cant play mpeg yet waiting on my licence

Menu speed is fine
comskip only works on shares in xbmc and has no black bars(unless im missing something?)
Tv remotes works really well with cec (anynet+ on samsung)

[stustunz]

Just gets better
Found an old ir receiver (philips mce) plugged it in set it rebooted and it works.

[JavaWiz]

Did you go with OPENELEC or Raspbmc?

[stustunz]

I went Raspbmc
things I read and watched said the cec worked

openelec boots faster and looked slightly faster but apparently its over clocked from standard.

Will load up another sd card with openelec on over the weekend and have a play.

To me the RPi is kind of like using the lowest end PC you can imagine with a reasonable h/w accelerated video card. Almost everything works just slower than then I'd like. Not just just CPU, memory, network etc are all bottlenecks. You also need to consider how you want to control it, I've bought a few mine USB keyboards that I use for most devices. Installing an IR receiver isn't hard but you have to be a hobbyist so if that if fun for you it can be rewarding. For NextPVR recording that aren't h264 you will need the mpeg2 decoder.

I Have installed openelec over clocked to 900mhz
Using X-newa ,auto start web client selected so it looks like npvr (X-newa is really well done its great having same interface on all clients thanks Martin)
using wired network everything is reasonably responsive
wireless N is also fine ,wireless G i gave up pretty quick trying that.(had to use powered hub for wireless dongle to work but worked straight away no config)
remote is through tv remote using cec (little bit of lag but ok)
plugged in mce receiver for a laugh and it worked pretty much once selected faster response than cec
keyboard and mouse worked fine (just standard logitech cheap wireless)
Playback of NZ recorded H264 is outstanding.
Playback of NZ recorded Mpeg is not always the best (deinterlacing) but i would probably not blame the raspberry pi for this rather our broadcasters.
Playback through http stream (recordings screen in x-newa)the timeline is correct and skip forward and backwards works great
Playback through shares(must be set up using share link not local folder on nextpvr server) the timeline seems to get a bit random but then comskip works although the way comskip works in xbmc is not the best(no balck bars to show where adds are and you dont seem to be able to over ride it when skips are not correct.So once it gets a commercial wrong and with the timeline being wrong you cant skip backwards. Remove the edl file and everything on the same file is fine skipping is correct (maybe i have something set wrong in comskip,i am still testing this)
Tv guide works great
Resume works
Start up of openelec is great also turns tv off when you walk away starts back up when you power tv back up
Skipping is pretty much instant.(edited advanced setting and changed bigskip(arrow up) amount to 4 minutes (thats how long 90% of out add breaks are)

to me this device is almost perfect as a cheap client as long as you dont expect comskip to work as good as it does in next pvr

[mvallevand]

Do you have comskip set up for making cut files or commercial breaks. The last number on each line in the file should be 3 You should have edl_skip_field=3 in your comskip.ini

I did just noticed the output_vdr=0 (dont have a clue what it does but im guessing i should have that set to 1 also)
I dont have "edl_skip_field" in my comskip.ini

Are there any other settings i should change. I have done searches on comskip and xbmc but have not had much luck on info.
I probably haven't given it as much time asIi could have as I didn't realise till last night that was my issueIi thought it was raspberry pi not reading the time line properly on a share.

[mvallevand]

I just use defaults except for that setting. Maybe it is only in donator's versions? You can edit a file manually to see if it helps.
