.JPG files created in LO Draw and Presentation by using the Export command won't play on an Epson projector which DOES play .JPGs created by other programs such as Corel PaintShopPro. I'm using 188.8.131.52 (64bit). The project does also play .BMPs and .PNGs created by Draw and Presentation. I have found a work around by copying the created .JPGs into Corel PaintshopPro the re-saving them as .JPGs. Curious, isn't it?
1. Create a drawing in Draw
2. go to File/Export/ choose JPEG
3. Save to USB drive and plug into the Epson projector
4. Projector will say 'Cannot play'
User Profile Reset: No
Should have displayed the image
Doing a quick search I found this for a random model:
For .jpg it has this laundry list:
Make sure the file is not:
Above 8192 × 8192 resolution
Over 12MB in size
Named with a .jpeg extension
Then I found this topic:
So it seems the problem is that we output progressive JPEGs without any option to choose non-progressive.
It seems like an uncontroversial feature request, so I'll set to NEW right away.
To losslessly convert from progressive to baseline, you could use jpegtran as discussed here:
jpegtran in.jpg > out.jpg
You can get jpegtran from https://jpegclub.org/
