title: ffmpeg sepia effect on video
body: <p>How can I apply simple sepia effect of a video using FFmpeg ? I am seeking for a single line FFmpeg command which I will be using in android.Though I have learnt <code>colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131</code> on official FFmpeg doc , but unable to apply it properly.Thank you.</p>
