if i don’t add subtitle the convert is correct:
ffmpeg.exe -i DearJohn.avi -vcodec libx264 -b 950 -f mp4 DearJohn.mp4
But when i add a subtitle like this, it does not work:
ffmpeg.exe -i DearJohn.avi -scodec copy -newsubtitle kid.srt -slang vie -sbsf text2movsub -vcodec libx264 -b 950 -f mp4 DearJohn.mp4
it notices At least one output file must be specified
I have tried subtitle .txt change .srt to .txt.
Can you have any idea?
