ffmpeg image conversion works for nokia conformation heic files but not iphone heic images

Below ffmpeg image conversion works for nokia conformation heic files but not iphone heic images

ffmpeg -i c001.heic -c:v mjpeg -frames:v 1 -pix_fmt rgb48 outs.jpg (works for nokia conformation files https://github.com/nokiatech/heif_conformance/tree/master/conformance_files but not iphone images )

For iphone images ,it throws the below exception [mov,mp4,m4a,3gp,3g2,mj2 @ 0000021bcaba9980] moov atom not found image4.heic: Invalid data found when processing input

Is there anything I'm missing

Not sure this works on images but try this ffmpeg command:

ffmpeg -i c001.heic -c:v mjpeg -frames:v 1 -pix_fmt rgb48 -movflags faststart outs.jpg

The -movflags faststart argument moves the atom files to the start of the file. This has worked for me for MOV files from iPhone. If that doesn't work in transcoding straight to JPG, first copy the file like so:

ffmpeg -i c001.heic -c:v mjpeg -frames:v 1 -pix_fmt rgb48 -movflags faststart c001_fixed.heic

Then attempt your original command.
