.Mov IPhone Video - comparing .mov to .mkv error
Hi!
There is a problem when trying to compare an original iphone .mov file to a converted file (mkv or mp4... doesnt matter) It only gives me the values "error" for PSNR, SSIM and VMAF...
The log states:
Stream #0:1 -> #0:1 (vorbis (native) -> pcm_s16le (native)) [Parsed_libvmaf_5 @ 00000184eaf50480] input width must match. [Parsed_libvmaf_5 @ 00000184eaf50480] input height must match.

Conversion failed!
I have an idea what it could or even probably is going to be... IPhone .mov files store the rotation of the video only in metadata... it doesnt actually rotate the pixels...
Meaning --> The Original is in reality 3840x2160 but rotated 90° via Metadata (for Portrait) The converted video is probably 2160x3840 without metadata rotation.
is there anything we can do inside the code to tell it to take that into account? Maybe that it uses the rotation in metadata and auto rotates for comparison?
thanks! Mem

How ffmetrics shows both files frame sizes? Have you tried to investigate the ffmpeg command that do the comparison? (you have not provided it)
