Can you guys point me on how to do a USB install on OpenELEC? I search a lot, but I didn't find any consistent information on how to do this in windows.

Assuming you only want /storage on USB:

1) Format an SD card with a single FAT partition
2) Copy SYSTEM, KERNEL (renamed to kernel.img), bootcode.bin, fixup.dat, start.elf, config.txt and cmdline.txt files to the SD card
3) Format the USB key with a single ext4 partition (you could use Raspbian on the Pi to format the USB key with ext4)
4) Configure cmdline.txt with "disk=/dev/sda1"

You could also format the USB key with two partitions - one FAT ~100MB, the second ext4 - and "boot" the Pi from the USB key by placing the SYSTEM file in the USB FAT partition, having specified "boot=/dev/sda1 disk=/dev/sda2" in cmdline.txt, but there really is little advantage in doing this compared with the single USB partition approach outlined above.

PS: @admins - this forum needs a sticky...

Hi

I'm running the latest build and having audio/video sync problem with live HD and HD recorded tv shows. I'm using NextPVR as my back end on a WHS machine which works well with my other XBMC on windows. The sync starts fine but the video skips and stops and becomes out of sync. Sometimes the buffering window comes up for a few seconds. SD DVDs play back fine. Sounds like a network problem to me but I don't know enough about the PI to know where to start. I'm on a wired network. I have the MPEG license.

Any help would be great!
Thanks

Does mplayer -dumpstream work for you or have you another tool in mind ?

Sounds possible. You'll have to confirm it suffers the same problem as the live stream. It is possibly that mplayer will fix the timestamps or repacketise the data and so avoid the problem, but it's worth a try.

As expected the dumped stream (with mplayer) doesn't show the problem ... and I do not have enough upload bandwidth to give you access to the stream to test.

I retried just after that the rtsp stream (in a strm file) and it stutters a lot during the first 3 seconds where it drops video frames but the audio stays off sync afterward.

If it can help you here is a mplayer log playing the stream

Hi rbej,
I just replaced openelec official 2.99.2 with your last build on my raspberry.
I also applied your suggested settings:
"For Rpi 512Mb set gpu_mem=256, cachemembuffersize to 5242880"

Since then, I'm not able anymore to watch tv steam from my dreambox dm800se using pvr addon vu+ or tuxbox client connection. The stream hangs as soos an it starts, just after 1 second.
Before, with 2.99.2 official, it didn't happen. I was able to watch at least sd channels.

Does it depend on settings above (gpu_mem op cachemembuffersize)?
Thanks

[rbej]

Gpu_mem and cache buffer size have no effect on watch Live TV. It must be something else

[papreston]

Hi all

I posted a few messages back about possible network issues while watching HD.
I found this page http://www.raspberrypi.org/phpBB3/viewto...28&t=20126
I put the sysctl.conf file inside the configfiles folder, It seems to have fixed my problem. HD live TV was MUCH better.

Just curious, since Frodo has been final for a few days now what are the differences betweenyour Frodo final builds versions 1,2,3?

EDIT: also wouldn't your build version of XBMC be considered "Gotham"? I'm just a little confused and any help would be appreciated.

[lowridin_guy]

I see the different revision dates. I guess I would have to look up change logs for each thing. So is build 13227 considered Frodo or Gotham? I thought earlier versions of XBMC were Gotham and now we are back at Frodo? That is what is most confusing.

[rbej]

Gotham is Alpha version Xbmc 13. Official OpenElec r13227 include Frodo. I decide support only stable version Xbmc. If OpenElec team will be support Xbmc 13 , i will support to.

[Slatri]

Tried the latest frodo build and the audio is still way out of sync more than 10 seconds. I will grab a log when I get home

The logs don't include timestamp information, so you will likely need to upload a sample (e.g. 100MB) of a file that exhibits the problem.

[Slatri]

How would I do that? I could also give you my dns and the plugin if that would be better. if you want to pm me I can the details. Thank you

Rbej Frodo Final Version 3

Rbej,
I've been happily running your builds for a couple of weeks now and was wondering if it would be possible to add the latest development MythTV PVR addon to your build.

http://wiki.xbmc.org/index.php?title=PVR...o_OpenELEC

I was able to compile it into openelec (it is a huge improvement over the version in Frodo) but doing it with all of your additional goodies is beyond my capabilities without a pretty specific how-to.

Thanks
