Am I doing any wrong?
dvd2concat never outputs VOB file. It outputs a text file which contains VOB relationship. The resulting text file can be used with ffmpeg or ffplay like the following: $ ffplay -f concat -safe 0 -protocol_whitelist "file,subfile,concat" \ -i dvd_video.concat $ ffmpeg -f concat \ -safe 0 -protocol_whitelist "file,subfile,concat" \ -i dvd_video.concat \ -c:v libx265 -preset medium -tag:v hvc1 -crf 23 \ -c:a libfdk_aac dvd_video.mp4 I have written a guide to use dvd2concat in Japanese.
