Unsupported image file format with align_image_stack

[Olivier Lenoble-Folleas]

Hello,

I have a video created with Magic Lantern on a Canon's reflex. The fps is 50 images per second alternated at 1600 and 400 iso for doing hdr video.

I use the script hdr.sh to :

- extract each image of the video, using ffmpeg, to a tiff file : it works

- align images by pairs using align_image_stack : it does not work

- make an exposure fusion using enfuse : not tested yet

After ffmpeg has extracted all the pictures of the video, I have :

Could not decode image: HDRb-000001.tifUnsupported image file format

Could not decode image: HDRb-000002.tifUnsupported image file format

Could not decode image: HDRb-000003.tifUnsupported image file format

Could not decode image: HDRb-000004.tifUnsupported image file format

Could not decode image: HDRb-000005.tifUnsupported image file format

Could not decode image: HDRb-000006.tifUnsupported image file format

Could not decode image: HDRb-000007.tifUnsupported image file format

Could not decode image: HDRb-000008.tifUnsupported image file format

Could not decode image: HDRb-000009.tifUnsupported image file format

Could not decode image: HDRb-000010.tifUnsupported image file format

...

I have to stop it with CTRL C

Could you please help me to solve it ?

Regards,

Olivier

Check your installed libtiff library. You have probably a version without packbits/rle support installed.
