As I didn't see another thread, I was thinking it would be a good idea to start an ongoing thread where we can report issues with the builds from the xbmc buildbot.

I'm currently running 26715 with a Crystal HD card and I'm having pretty severe networking performance issues. When playing back 720p and 1080p files, it will only play a few seconds before buffering. When playing back files locally, they work just fine.

I seem to recall someone else mentioning this, so I didn't know if it was a known issue or not. I didn't really see anything worthwhile in the logs, but would be happy to post them if helpful.

Hate to say it but without knowing your network setup, such a report is rather useless. There's no info about if this is a new condition, i.e. a previous version of XBMC on the same platform had better network performance. And no xbmc.log posted to http://www.pastebin.com. I might as well toss darts at a dart board and make wild guesses Smile

AppleTV is connected via ethernet interface to a Layer 2 gigabit switch, which then goes upstairs to a Layer 3 gigabit switch, which then hits my fileserver which is running samba on FreeBSD. I haven't run XBMC for a while on the AppleTV, but playback works great on the Linux-based xbmc system sitting next to it, although it has a gigE interface. 100mbit should definitely be enough to play back 720p files if not 1080p files.

I will try to post some logs tonight. Just wanted to ask if network performance was already a known issue.

Thanks!

In other words, wired and no wireless Smile

, many people try pumping 720p/1080p over 802.11g and it's just not fast enough.

100Mb is adequate for 1080p even VC1 bluray rips.

Indeed.

Here is a section of the xbmc.log trying to play back a file over the network

audio queue is getting drained. if you have a keyboard attached, type 'o', this brings up a/v stats. look at aq and vq and a/v ratio. What do you see ?

If aq, vq are zero, pause, they should fill up. unpause, they should stay full.

I have an issue with an SMB share on a WinXP box, it just can't keep up with feeding VC1 bluray from the BD disk. Copy the bluray image to a linux box with SMB shares, no problem with feed. Network is not saturated, WinXP box has plenty of CPU avaliable, just can't get it to feed a 30-35Mb continuous stream.

I'll enable the keyboard and see what I can find out tonight - stupid work getting in the way.

I'll see if NFS or HTTP works better as well.

dan1son · 2010-01-15, 20:01

For what it's worth, I have better luck (speed wise) with NFS over SMB. My fileserver runs Ubuntu 9.10 server with my Revo and ATV hooked up to 802.11n bridges.

I can stream blu-ray rips over N with NFS. SMB can't quite do a full rip, but it handles 1080p re-encodes or 720p videos fine.

For some numbers... I get stready transfers in the 50mbps range from NFS, and in the 20mbps range from SMB. HTTP is around 50mbps as well. NFS seems to have minimal overhead on my setup.

runelind · (This post was last modified: 2010-01-16, 03:58 by runelind.)

Performance is much better with HTTP. I no longer get the buffering screen, however I do get moments every once in a while (more frequent with 1080p) when video slows to slow-motion, while audio plays fine.

http://pastebin.ca/1753074

Network appears to be maxing out at 5mbit according to bmon on my BSD box, well within 100mbit limits.

EDIT:

And now I can't get it to do it at all, plays back perfectly over http. Go figure ;p

Still unhappy with SMB

runelind · 2010-01-17, 21:39

Upgraded to svn26936, and the SMB problems are still present. I was also having buffering issues with http decoding SD files. Same issue as decoding HD files over http: audio would continue to play while video would turn to slow-motion.

runelind · 2010-01-17, 22:07

I'm also having issues with XBMC crashing when starting or exiting out of videos. Here is a chunk of the xbmc.log during a crash during startup of a video. This is over http:

I have to do a kill -9 on the XBMC process and restart to fix the issue. I would say it happens about 50% of the time starting or exiting out of playback.

Let me know if you want debug output

**Bobby Blixberg** · 2010-01-18, 12:46

When I try to download r26957 on apple TV it fails with message "An error occured."

I could install it manually of course (the latest nightly build is r26973), but what do I have to enter into the console (NOT using the launcher) in order to do that?

Thanks for any advice.
