ffmpeg -i data/video.mp4 -vcodec h264 -b:v 1000k -acodec mp2 data/output.mp4 |
Thanks, It works for me
from 137,6MB tobe 61,5MB
Thanks. it still work good.
hint:- if it increase the size of converted video, then try to reduce the bitrate (-b:v 1000k to 500k) for ex.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4
to
ffmpeg -i input.mp4 -vcodec h264 -b:v 500k -acodec mp3 output.mp4
It is not working for me sir...
showing me unknown encoder 'h264' and same for 'libx264'
I even tried other commands like:
'-i ${_storedVideoOne.path} -vcodec h264 -acodec aac $outputPath';
'-i ${_storedVideoOne.path} -vcodec libx264 -crf 28 $outputPath';
using with flutter_ffmpeg plugin
I tried mp2
and mp3
, all no audio on ios13.6, windows and android ok.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp2 output.mp4
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4
Finally I use with no -acodec
, all ok, and file size no big different.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k output.mp4
One-line bash script for Debian GNU/Linux
$ cd ~/Videos
$ for file in .mp4; do ffmpeg -i "$file" -vf "scale=-2:240" "Output-${file%.}.mp4"; done
anyway i can preserve my subtitles while transcoding and compressing from mkv to mp4? map doesnt seem to work.
