Hello,

How can we use ffmpeg to transcode SD channels of resolution 720*576 to HD
format .
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 .

HI,

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
