#7752 new defect

Rotation metadata is not honored by crop filter in ffplay

Reported by: pekarna Owned by:
Priority: normal Component: ffplay
Version: git-master Keywords: rotate
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no

Description

Summary of the bug:

Using the 'crop' filter,
the ffplay preview of cropping the videos that were rotated just by setting the metadata behaves as if there was no rotation.

That means: If I want to crop a rotated video,
ffplay takes the cropping parameters as if it was not rotated;

ffplay -i VIDEO-rot.mp4 -vf 'crop=in_w*(1-0.5-0):in_h*(1-0.31-0.1):in_w*0.5:in_h*0.31'

while the actual cropping takes them properly.

ffmpeg -i VIDEO-rot.mp4 -filter:v 'crop=in_w*(1-0.5-0):in_h*(1-0.31-0.1):in_w*0.5:in_h*0.31' -c:a copy VIDEO-cropped.mp4

How to reproduce:

1) Have an MP4 video
2) Rotate it with metadata:

ffmpeg -i "$INPUT" -metadata:s:v rotate="180" -codec copy "VIDEO-rot.mp4"

3) Preview cropping with ffplay and do the cropping with ffmpeg and notice that the crop filter params need to be rotated.

  • Version changed from 4.1 to git-master

Is the issue not reproducible with ffmpeg?
Please test current FFmpeg git head and provide command line together with the complete, uncut console output and a sample to make this a valid ticket.

I was never able to compile ffmpeg properly with all features. Are there any statically linked builds of Git master for Linux? Thanks

comment:5 Changed 2 months ago by cehoyos

Where did you download the version you tested?

comment:6 Changed 8 weeks ago by pekarna

The ffplay is from Ubuntu's official repository.
The ffmpeg is from https://www.johnvansickle.com/ffmpeg/
However, ffmpeg behaves as per documentation, only ffplay behaves differently.
