I have a canon G7 camera - before v5* all pictures (jpg) whatever the orientation are displayed ok (sony bravia through sony BD 570)

since v5* : very very slow picture slide show and portrait pictures are not loaded (keeps on "loading" )

i tried several configurations but nothing seems to help
it looks as if servio cannot reorientate the picture
suggestions ? :(

This portrait file is in Motion JPEG, this is a video, select and browse into the proper section on Sony XMB menu : Video.
or rename this file with *.avi extension and browse in Sony Video section

No, it actually is jpeg. Serviio doesn't use FFmpeg to detect images or audio files, so no point looking at this output.

You could only play with

  Code:
<AutomaticImageRotation>true</AutomaticImageRotation>
<LimitImageResolution>false</LimitImageResolution>


where the first will rotate the image if the EXIF metadata include the rotation of the image. But it's possible that the TV can do it automatically, in that case it should be false.
The second will resize images with resolution higher than 4096x4096, which doesn't seem to be the case of this file.

Ooh, so how Serviio detect images or audio type files, only with file extension and EXIF (if embedded)?

It uses other (Java) libraries to extract metadata from audio/images.

Is there any way of detecting image or audio file type without extension?

Dear All,
How to read a big JPG by steps and display instantly
This is to decrease the waiting time to display the image in LAN.
Users prefer to hv the screen change gradually than waiting for
loading complete and image come out.

I believe this is something this is player dependent. I don't think there's anything on the Serviio side that can do this.
