    Sorry I cannot upload the jpeg due to its size.

    This is a wanted "feature": when there are several (more than 24, arbitrary choice) files with consecutive numbers (IMG_1731.JPG, IMG_1732.JPG, IMG_1733.JPG...), MediaInfo considers that this is a video stream with one file per image, and the size is the total size of the images (IMG_1731.JPG up to the last file).

    This kind of "stream" is often used in professional systems, and I did not currently find a way to differentiate consecutive video frames from camcorder and pictures from a camera.

    I don't plan to change this behavior (maybe an option to deactivate the feature?)

    Given the fact that by default numbering is incremented by one, this is a crasy assumption. My digital camera is not even able to generate MJPEG!

    So at least give an option that can be passed up to the library

    besides, even if I call it on a single photo it says the same thing!

    It even more crasy as if I understand correctly calling mediainfo on the same file but simply moving the file to annother directory result will be diffreent.

    This is an asumption that people who pay me to implement such feature have.
    As I said, I can not make the difference between a camcorder recording 1 frame per file and your camera. MediaInfo is not used a lot for stand alone images, this is not my priority.

    > besides, even if I call it on a single photo it says the same thing!

    In a repertory without the other files?

    Changed to feature request: option for disabling the automatic detection consecutive image files as a video stream.

    Accepted.

    Warning: non-paid feature request are set to low priority, I don't know when I have time to handle it.
    If you desire to accelerate the development, don't hesitate to contact me for a quotation.

    BTW: you have seen many camera producing 3 888x 2 592 (e.gf 4K video)? Given the fact you read the directory, I guess I can find the offending code myself. Its the beauty of open source.
