Pillow can raise
ValueError("No data found for frame")on some MPOs whenseeking a later frame with missing/invalid data. This prevented LoadImage
from returning the successfully decoded primary image.
We wrap iteration of the frames and if first frame is ok(only for
MPOformat), we ignore other decoding errors.Exception happens here: https://github.com/python-pillow/Pillow/blob/2ebb3e9964bcfb46e2b8dcaec1917caf67730a7d/src/PIL/MpoImagePlugin.py#L152-L155
Edited: Alternative PR was created with less changes and keeping the current logic.
