JPG frame sets: Timeout reading some files #61

Closed nschlia closed 4 years ago

nschlia commented 4 years ago

When accessing files in arbitrary order some reads fail. Works for BMP and PNG, but not JPG.

For example, run with desttype=jpg and try to copy these images:

000204.jpg
000004.jpg
000104.jpg
000207.jpg
000007.jpg
000107.jpg

Result:

'frame_test_pal.mp4/000204.jpg' -> './000204.jpg'
'frame_test_pal.mp4/000004.jpg' -> './000004.jpg'
cp: Error reading 'frame_test_pal.mp4/000004.jpg': Timeout
'frame_test_pal.mp4/000104.jpg' -> './000104.jpg'
'frame_test_pal.mp4/000207.jpg' -> './000207.jpg'
'frame_test_pal.mp4/000007.jpg' -> './000007.jpg'
cp: Error reading 'frame_test_pal.mp4/000007.jpg': Timeout
'frame_test_pal.mp4/000107.jpg' -> './000107.jpg'
