-====== dvd_mkv ====== 
  
-I'd like to be able to duplicate what HandBrake does using libav directly. 
- 
-Here's what I've got so far, to duplicate my setup: 
- 
-  * x264 slow preset, high profile, level 4.1, CRF 14 
-  * 60 fps 
- 
-<code> 
-dvd_copy dvd.iso -c 1-1 -o - | avconv -y -i - -vcodec libx264 -acodec libfdk_aac -tune animation -ab 160k -r 60 -vsync cfr -crf 14 -x264-params ref=10:subme=8:trellis=2:keyint=240:rc-lookahead=50:direct=auto -bufsize 78125k -maxrate 62500k -t 1 -color_primaries smpte170m -color_trc smpte170m -colorspace smpte170m dvd_encode.mkv 
-</code> 
- 
-Note that Handbrake will set the colorspace to BT.709 if it doesn't recognize what it is (source: I lost it, but I remember it being verified by a second one). 
- 
-See [[https://video.stackexchange.com/questions/16840/ffmpeg-explicitly-tag-h-264-as-bt-601-rather-than-leaving-unspecified|here]] for the same scenario I was running into -- comparing mediainfo output from a HandBrake encode to a direct ffmpeg one. 
- 
-I can't figure out how to use my own avpreset files which is annoying, but then I thought about how it's probably a good thing to have one less file to track when making changes, so oh well. :) 
- 
-TODO: 
- 
-  * detect and apply cropping 
-  * detelecining 
-  * setting SAR and DAR 
- 
-Eventually: 
- 
-  * a way to rip VobSub as well 
-  * MKV chapters 
- 
-Other than the todo list, it works great. :) Proof-of-concept invented!
