By analysing the binary my colleagues found that jpegs with one big quantization table won't work. If you open the jpeg and save it again with Gimp (or another image tool) the quantization table will be split up into multiple tables of smaller size. Can anybody confirm this?

Hi Rudolph,

Thanks for your response.

We did the open and save again trick with Gimp too and we also tried some jpeg analysis like you did. But we can't find the difference. Unfortunately this jpeg is only one of an ongoing jpeg stream so we can't just save the jpeg again with an external tool to display it. We need to know what we have to change at the stream source.

Hi,

we are trying to display a jpeg image on a display connected to the BT815. But we got

Quote
ERROR: unsupported JPEG in cmd_loadimage()

followed by multiple

Quote
ERROR: display list overflow

The error message is clear but we can't find a reason why the jpg is not supported. The data sheet says that progressive jpeg is not supported but our jpeg is not progressive.

I attached the unsupported jpeg. What do we need to change to display the jpeg?
