mkv TO mp4
-
@בערל מכיון שגם MP4 וגם MKV הם פורמטי מכל, אז הסיומת של הקובץ לא אומר כלום על הקידוד של המדיה שכלול בתוכו.
ייתכן שזה מקודד בפורמט שנתמך על ידי MP4 ואם כן הכי מהיר והכי איכותי יהיה פשוט להעתיק את ערוצי השמע והוידאו ישירות בלי שום המרה.ffmpeg -i input.mkv -codec copy output.mp4 -
@yossiz תודה!
זה מה שנותן לי בהרצת הפקודה:

@yossiz אמר בmkv TO mp4:
הממ... אולי התחביר כך:
ffmpeg -i input.mkv -codec copy -strict -2 output.mp4שוב יצר קובץ ריק..
