JPGD_UNEXPECTED_MARKER & M_RST7 failing on the Nexus 4 #4

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Only happens in the Nexus 4 device. (Android 4.3)

2. When taking a JPEG picture, the JPEG data is passed for decompression into 
the method: decompress_jpeg_image_from_memory method

What is the expected output? What do you see instead?

Decoding fails. Debugging the library I've found that the error code is 
"JPGD_UNEXPECTED_MARKER", and the marker itself that seems to make it fail is 
"M_RST7"

Further testing on other devices, seems that the issue is only with the Nexus 
4. 
So seems very specific to the type of Jpeg that generates this device.

If you're still out there - please send me the image and I'll debug it.

@richgel999 Not OP, but we have a similar error when decoding the example files below. In our case they were generated in Blender and then processed in Adobe Lightroom.
