I have been searching all the web on how to downscale 4k video so that it can play on my non 4k TV.
My 4k video has a resolution of 3840 x 2160 with an audio format of pcm_s16be in a mp4 container. I am trying to convert it to 1920 x 1080 with an audio format of aac. I use Lubuntu and have been experimenting with the command lines without success.
Update -- After further searching I found this code which converts the audio from pcw to aac
ffmpeg -y -i C0010.MP4 -vcodec copy -strict experimental -c:a aac output-fileC0010.MP4
