Ideally we should stretch the shape of the kernel with the scaling ratio.

These were the kernels:

0.00 Sinc over the range +-3*PI with Hamming window applied,
0.02 Sinc with Hamming window applied,
0.04 Sinc over the range +-2.5*PI with Hamming window applied,
0.06 Sinc,
0.08 Sinc with Blackmann window applied,
0.10 Sinc with no side lobes,
0.12 Sinc with half the first side lobe
0.14 Mitchell Netravali (with B=1/3,C=1/3)
0.16 nearest_neighbour,

Here's another suggested by the image scaling guy (you can just enter that while video is playing):

Code:
vcgencmd scaling_kernel 0 -4 -8 -14 -18 -19 -16 -8 9 39 77 122 166 206 237 255 255 237 206 166 122 77 39 9 -8 -16 -19 -18 -14 -8 -4 0
It's a cubic with A=-0.5.

To my eyes (TV sharpness at zero), 0.08 exaggerated compression artifacts more than 0.14. My preference is for 0.14. Although I would be really curious about comparing it to Lanzcos3.

Yes please, another vote for Lanczos3 if possible... no idea on how to do it myself. Confused

I liked 0.08 so far, will compare to 0.14 again and report back.

@popcornmix,MilhouseVH do you see anything in the log?

Can you try again with log enabled from boot.
i.e. enable debug. Reboot. Play an audio file.

Hi Gang. 1st time trying the millhouse build. New openelec beta upgraded to latest build.

Here's my debug logs.
http://sprunge.us/KZCC
http://sprunge.us/cPAZ

1st one is me just trying to play the bdrx file via wired network with an eventual error that it can't play it.. 2nd one is a continuation to a different m2ts file that is also unplayable

I never had this issue on my old frodo raspbmc setup. It also seems to take ages on thumbnail generation. The date/time stamps at the end is not quite correct as it took about 2 hours to be become responsive again after it said it closed the samba session (even though my ssh session did not drop). I do admit that my previous setup had a shared mysql config which this does not have as yet (not sure if that will make a difference).

I probably wont use the pi to play these big files.. but just thought I'd mention it in case there's an underlying issue

Thanks

Disable "extract thumbnails and video information" in settings/video/file lists. (Everyone should do that).

There's not much information in log. It could be a network issue caused by fiq fsm patch. Can you try adding "dwc_otg.fiq_enable=0" at end of cmdline.txt.

@popcornmix SORRY, My bad, I have Stereo sound -HiFi issue fixed. Thank you.

I have a weird bug - I upgraded from a generic Gotham beta build to the March 30th MilhouseVH build, and quite a few of my addons have stopped working. System Info is showing that I am running 14.0-ALPHA1 instead of Gotham.

**da-anda** · 2014-04-01, 14:09

MilhouseVH builds are built from XBMC master branch, which is 14.0-ALPHA1. But XBMC master is as long as Gotham is not released the same as Gotham branch, just without the Gotham splash - so it contains same fixes.

@popcornmix, @sraue
I tried to rescan my music library yesterday using 330 build from MilhouseVH (so latest test build). I'm using a USB WiFi stick and everything worked fine as long as the screeensaver didn't kick in. Everytime I got back to the PI and wanted to check it's progress (since it's taking a while) it had a black screen and was frozen. Cutted power and rebooted, started import again and ended up with same issue. Then I disabled screensaver and tried again and import finished. Odd thing was though that all graphics where suddenly gone in my skin (Eminence) after that import and I couldn't switch to Confluence and back. XBMC told me that skin files where missing which was not the case as a reboot showed. So I assume it might have been a memory issue (leak?). I'm running 512MB model B with AFAIK default/common GPU mem settings. Unfortunately I don't have a debug log of this nor my PI at hand right now, but I could try to reproduce (whiping music db and rescan). Just tell me what you need or what I should test (I'm a linux noob, so I would need instructions for any console commands I should check when issue occurs again)

ijsbeer79 · 2014-04-01, 14:10

The version number is correct, that's the version number these builds are providing.

I guess information on reproducing it would be useful. Do the music scan from a clean boot with:
Same settings as locked up before. Check it is repeatable.
Same settings as locked up before but with screen saver disable.
Same settings as locked up before but with confluence skin.

It would be useful if during the scans you run Milhouse's bcmstat.sh script. Run:

Code:
./bcmstat.sh xgc

That outputs info on free arm and gpu memory. You can see if one of those is close to zero when the crash happens.
I'm also interested if the ssh connection is still working after the hang.
I'm also interested if you enter "killall xbmc.bin" (which should restart xbmc) if xbmc is working fine (and bcmstat memory usage is back to normal), or if it requires a reboot to recover the memory.

Sweet... did that, rebooted, and it started playing within a few seconds of pressing OK.

A debug xbmc.log showing the issue may help.

Nothing obvious there (a complete log would be more useful, but still probably wouldn't show the problem).
A sample file that has the problem would be more useful.
