This has been mentioned elsewhere across the internet but its perhaps a real problem if you're running on a Raspberry Pi with an SD Card.
It's been reported that the GPU cannot handle progressive jpegs and indeed I get two entries in the log as per this example:-
2019-12-12 10:45:45.130 T:1540354784 WARNING: COMXImageFile::GetCodingType progressive images not supported by decoder
2019-12-12 10:45:45.132 T:1540354784 NOTICE: LoadJpeg: unable to load /media/Multimedia Drive/Pictures/test/Progressive Jpeg.jpg
There is no warning if I use a Baseline Jpeg but the Notice still appears as per this example:-
2019-12-12 10:37:16.226 T:1793061600 NOTICE: LoadJpeg: unable to load /media/Multimedia Drive/Pictures/Five Star/Five Star (23 of 68).jpg
Despite these entries the image displays correctly. Using a PNG or TIFF doesn't produce any warnings.
Why does this matter to me? I run my Raspberry Pi with music almost every day while playing a slideshow which changes the image every 10 secs. This means I get at least one entry added to the log every 10secs. Over the last 2.5 years since I first started the system this represents somewhere in the region of over 1.5 million writes to the log file on the SD Card just for these image warnings. For 2 years my system ran ok and in the evening I would switch to watching a video or two but in the last couple of months when I do this the video would crash - first audio would stop, then the video would stop. Sometimes Kodi completely stops and sometimes I would be lucky to be able to get back to the home screen. This happened with different videos ( all MKV rips from DVDs) and even a reboot would not improve the chance of playing the video correctly.
In the end I reloaded a new Sd Card with OSMC and Kodi 18.5 - admittedly a later update than my previous system - and the problem seems to have gone away.
The entries about Jpegs in the log file seem unecesarry and potentially causing wear on SD Cards. Is there any chance they could be removed?
For now I'm going to convert all my images over to PNG or TIFF - however the log fille still continues to get periodically written to with other information which most of the time isn't needed.
Any comments would be appreciated.
Thanks for your time in reading this.
