I have found a bug. I think it is in the 1.4.0 stable too.
When there is no thumb in the cache.
- Change to list view.
- Stay on a move which still there is not thumbnail yet.
- Wait for thumbnail is generated.
- The small thumb is refreshed but the large thumb stay empty.
- If you move to another move and move back, the large thumb freshed too.
Did you work/update the video part code ? I just read my locked SD card and ffmpeg was running but failed because MP can't write to it.
So use temp folder when created single picture and global would be nice
EDIT : Does we need command line addon on ffmpeg to tell to us temp folder ?
If we can sort out this, we can port the code to TV side ?
Ps : About above error, i didn't try to debug it lol
