I wish i can find
ffmpeg help here at stackexchange. I'd been re-encoding old videos to libx264 to save up some storage space, as I thought it should be working based on documentation seems failing to me. I'd been using the snippet below to re encode all files:
ffmpeg -i "$file" -y -acodec copy -vcodec libx264 -scodec copy -threads 12 -x264-params keyint=240:min-keyint=20 -profile:v baseline -level 3.0 "$output"
-acodec copy i believed should be able to
map all audio streams and just copy them all to the new container right? but I can't understand why all those
dual audio videos are being re-encoded to a single audio video, the non-default audio stream was omitted/removed.
any idea how can I copy all codecs audio, subtitle, but only the vcodec to be re-encoded to libx264?
