So, hier nun die Info an alle, so dass diejenigen, die das gleiche Problem haben wie ich, dann wissen warum es nicht geht (wobei ich immer noch nicht verstehe, warum mein DNLA vom PC so unterschiedlich von dem der DS sein soll - wie gesagt vom PC geht es ja):
"Dear xxxxx,
Thank you for waiting.
The DLNA protocol by default has limitation to image resolution larger than 4096*4096:
1.The DLNA protocol has a restriction on resolution by DLNA, max is 4096x4096, if your images are larger then they may not be added.
2.Twonkey has statement "fixed: Display "non-DLNA" JPEG files (i.e. image dimension exceeds 4096x4096) with REGZA"
So this may be why you use Twonkey on his PC and the 18MP (5184x3456) image work on your TV while DS does not.
If the image's resolution is larger than 4096*4096, server still send original image resource to DMA. But there is one thing different
from its size less than 4096*4096.
1. If > 4096*4096 (5000*4000), media server will send packet like these
<res protocolInfo="http-get:*:image/jpeg:;...." resolution = "5000*4000">
http://this is original image URL</res>
<res protocolInfo="http-get:*:image/jpeg:;...." resolution = "120*80">
http://this is thumbnail image URL</res>
2. If < 4096*4096 (3000*2000), media server will send packet like these
<res protocolInfo="http-get:*:image/jpeg
LNA.ORG_PN=JPEG_LRG;...." resolution = "3000*2000">
http://this is original image URL</res>
<res protocolInfo="http-get:*:image/jpeg:;...." resolution = "120*80">
http://this is thumbnail image URL</res>
When image's resolution is larger than 4096*4096, server won't send DLNA.ORG_PN=JPEG_LRG in original image <res>
In DLNA's spec, it only define the largest resolution up to 4096*4096 as JPEG_LRG.
Some DMAs are sensitive to DLNA.ORG_PN. If these DMA don't see DLNA.ORG_PN=* in <res>, they will skip this <res>, and find another <res>.
As the result, these DMA only see the thumbnail images.
So currently this is a limitation of DLNA at this stage.
However we will file a feature request to PM and developer for future analysis and evaluation to see if we could have overcome or have a workaround about this DLNA limitation. so DS media server has chance to be enhanced in the future.
Thank you.
Best Regards
