picture resize problem with ps3 and 4.4.4 RC1 (QNAP TS-109)

Post by mbehr » Sat Feb 09, 2008 7:51 pm

Hi,

I got a picture resize problem while viewing pics with the ps3. Pictures with a jpeg size 2560*1920 get scaled down to approx 200*160 pixels (PS3 zooms automatically ~800% at 1080i).

Any help? (I tried adding PX:1920 PY:1080 to clients.db but then the PS3 can't connect at all).

(Update: in the cache I can see the file 3 times: ...-source, ...(160,160), ...(640,171). I guess the 160,160 is the preview image. But where does the 640x171 come from? And why isn't the embedded thumbnail used as preview image?)

Update2: The problem is not PS3 specific. It appears on the PC with Nero ShowCase as well.
This seems to be due to a bug generating the twonkymedia.main.db. The picture size seems to be badly parsed on those pictures:
grep -A 10 P4030002.JPG twonkymedia.main.db
3C045/share/Qmultimedia/Bilder/C50Z/Album/Tom+Lina/unsortiert/P4030002.JPG

28006196609
26007160x120
250046586
240047218
43012125831680x33621888 <- this is a very large picture! On windows it shows up as Width 2560 x Height 1920

whereas on other good working pictures its eg: 430093888x2592 (3888x2592)


In hex the picture size detected is 7800A00 x 2010780. The correct size would be: A00 x 780.

Best Regards,
Matthias

I get this on ps3 also, at least 95% of jpg's have been scaled to 160,160

I got a reply from support@... They confirmed it's a bug in the exif-parser and will be fixed in the next release.
(It's not PS3 related as it happen with a PC client like Nero Showcase as well.)
