aspect ratio is changed using ffmpeg sameq and codec copy
- by Vishal Parekh
i am using ffmpeg to extract clip from mp4 video,
i tried with "-acodec copy -vcodec copy" and "-sameq"
in both, aspect ration of generated file is changed.
(
ffmpeg -sameq -i "input file" "output file"
ffmpeg -i "input file" -acodec copy -vcodec copy "outputfile"
)
source file is of aspect ratio
sar=4:3
dar=4:3
new file is has aspect ratio
sar=4:3
dar=1:1
please help me to solve this problem,
one weird thing is when i see details in another video tool, it shows me
sar=4:3
dar=4:3
of source video
but when i use command ffmpeg -i sourcefile, it shows me
sar=300:400
dar=1:1
thanks
