# We have now video stream `*.264`, audio stream `*.ac3` or `*.aac`, and chapters `*.txt`. # `ffmpeg -i "01-sample.mpg" -vf cropdetect -f null -`. # Resizing & cropping: If needed, use also `-vf crop/resize`. # If you have interlaced video enable interlaced mode top field first: `-tff`, # `-force-cfr` is to keep constant frame rate CFR (instead of Variable FR). # Use CRF method (Constant Rate Factor) - no two pass needed: # Before proper encoding, extract small sample just for test: # Encode video stream to `H.264/MPEG-4 AVC` format. # Then prepare OGM chapters file: create it manually, (sample provided for reference), # We need to extract times in `HH:MM:SS.mmm` format: & mplayer -identify -frames 0 "VTS_01_0.IFO " # and "Menu", respectively, somewhere in the output. # Using `mplayer` or `mediainfo` extract chapters timestamps. # `-map IID:SID` - select streams to process, `IID` - input id, `SID` - stream id. # `-y` - overwrite output file without asking. # `-c copy` - set `copy` encoder - to simply copy selected streams (v for video and a - audio). # `-i "concat."` - file input using `concat` protocol. # encode them to `AAC` (by default 128kb/s), this is good enough. Titles 2 and 4 both have just `PCM` 2 channel audio.

Audio stream (`AC-3` with 6 channels) is also copied directly Video stream (`MPEG-2`) is simply copied to mpg file

# Using `ffmpeg` concatenate `VOB` files into full titles, demuxing video and audio # streams formats & ids, resolutions, fps, durations, chapters. # Before start use `mediainfo` & `ffprobe` and note down informations about the source material: # the official builds, 圆4, when possible. # Tools needed: `mediainfo`, `ffmpeg` & `ffprobe`, `x264`, `mkvmerge`, `mplayer` (optional). # No need for MeGUI, Avisynth, Handbrake etc. # Convert DVD Video to MPEG-4 in MKV without GUI, using only CLI (Command Line Interface) tools.
