I used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.
But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.
Here's the console output from a portrait video using ffprob command:
command:
ffprobe -of json -show_streams <directoy_path>/standard/PORTRAIT.m4v | grep rotate
Can you please guide me what am I doing wrong? Or with a new version of ffmpeg what changes should I make in my query or command to get the video rotated perfectly?

How to detect rotation angle of video uploaded from any smartphone like android and iPhone
How to detect rotation angle of video uploaded from any smartphone like android and iPhone using ffmpeg 2.8
Feb 3, 2016
I used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.
But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.
Here'r the commands I was using:
To check rotation angle:
ffprobe -of json -show_streams {$input} | grep rotate
if rotation angle found then using "transpose" attribute/option to rotate the video
and add above transpose attribute in the final command below:
ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".<transpose from above code> ."' -threads 0 -ab 64k -s {$resolution} -movflags faststart -metadata:s:v:0 rotate=0 {$output}
But not the query is not showing the rotation.
Here's the console output from a portrait video using ffprob command:
command:
ffprobe -of json -show_streams <directoy_path>/standard/PORTRAIT.m4v | grep rotate
output:
