Subject: [FFmpeg-user] SD channels to HD
How can we use ffmpeg to transcode SD channels of resolution 720*576 to HD
So we can obtain best picture qualtiy for live streaming , wihtout
interlace and frame drops .
I am using ubuntu server and have compile ffmpeg on it . please advise on
SD to HD conversion .
you could look at the filtergraph command and its options and look at how to scale and pad the video to create a letter box formatted output.
ffmpeg -i input.mp4 -vf "scale=..., pad=..." output.mp4
help docs is a good place to start https://trac.ffmpeg.org/wiki/FilteringGuide
