VIDEO_TS to Ripped MKV

• The ffmpeg command is in ffmpeg package, from rpmfusion free. It's not in Fedora proper because of patent issues, I believe.
• -i concat:VTS_01_1.VOB\|VTS_01_2.VOB\|VTS_01_3.VOB marks that input file is a direct join of the three VOB files listed, the backslash is to escape the "|" so that it's seen by ffmpeg instead of bash.
• -map 0:v tells that ALL video streams are to be copied/transcoded.
• -map 0:a tells that ALL audio streams are to be copied/transcoded.
• -c:v libx264 tells that for video streams we'll use libx264 codec (i. e. we'll transcode to h264).
• -crf 18 tells that we want to use Constant Rate Factor, value 18 (which might be a bit of overkill, but I don't want to sacrifice quality for space and I don't have the time tune it).
• -vf yadif use YADIF deinterlacing, because I don't wanna keep interlacing in the video – I'll be playing it on a computer, after all.
• -c:a flac tells we'll be using FLAC for audio streams. It's free and lossless. Again, it might be overkill, but I like to keep the original sound without using nonfree codec like AAC or AC3.

ffmpeg-rip-dvd.sh

ffmpeg -i concat:VTS_01_1.VOB\|VTS_01_2.VOB\|VTS_01_3.VOB -map 0:v -map 0:a -c:v libx264 -crf 18 -vf yadif -c:a flac aikido.mkv

works like a charm. Thanks
