 ====== Encoding Specifications ====== ====== Encoding Specifications ======
  
-like to have specifications for encoding content so that I have a snapshot of settings that I used at the time.  Doing this, it allows me to verify that everything works across all devices, and expectations and bugs are noted.+Here's the specs use to encode my DVDs:
  
-==== dlna-usb-1 (created 2014-07-19====+  * HandBrake 1.0.2 
 +  * Matroska 
 +  * H.264 
 +    * Level 4.1 (what Blu-rays use) 
 +    * High Profile 
 +  * x264 
 +    * slow, slower, veryslow, or placebo preset (slow by default) 
 +    * animation, film, grayscale tuning 
 +    * smpte170m color matrix 
 +    * CRF 23 to 18 (as desired) 
 +  * Video 
 +    * detelecine or decomb as-needed 
 +    * 30 or 60 constant frames per second 
 +  * Audio 
 +    * AC3 re-encode or FDK AAC encode depending on desired quality 
 +  * VOBSUB or Closed Captioning as available 
 +  * Chapter markers

-MPlayer 1.1-4.8 on Ubuntu 14.04 has a bug where the subtitle language code does not display in the OSD.  The file is properly tagged, and there are not any issues with the Matroska container metadata. ​ Exists in MPlayer 1.1.1 as well. +
- +
-==== dlna-usb-2 (created 2014-07-22) ==== +
- +
-Same as above, but changed libav version to 9.14.  Previous version was unspecified. +
- +
-==== dlna-usb-3 (created 2014-07-24) ==== +
- +
-The Gentoo ebuild for HandBrake 0.9.9 has a bug where it does not detect closed caption video on DVD streams. ​ This was confirmed by building the same version from source and running the same tests. +
- +
-Decided to move to building HandBrake from upstream'​s source, using the last SVN commit as the latest version. +
- +
-<​code>​ +
-svn co svn://​svn.handbrake.fr/​HandBrake/​[email protected] +
-</​code>​ +
- +
-Here's my configure script: +
- +
-<​code>​ +
-./configure \ +
-        --launch-jobs=0 \ +
-        --force \ +
-        --enable-x265 \ +
-        --enable-fdk-aac \ +
-        --enable-libav-aac \ +
-        --enable-avformat \ +
-        --disable-gtk \ +
-        --disable-gst +
-</​code>​ +
- +
-HandBrake now has the option to use libavformat for the container, in addition to internal libmkv and mp4v2: av_mkv, and av_mp4. +
- +
-The command-line options also were simplified replacing --h264-* with --encoder-* +
- +
-All said, here's an example of the changes to the command line: +
- +
-<​code>​ +
---encoder-preset medium --encoder-tune animation --encoder-profile high --encoder-level 3.1 --format av_mkv +
-</​code>​ +
- +
-Noticed on this build that HandBrake was setting the vbv-maxsize and vbv-maxrate higher than the H.264 level permitted (3.1 caps at 14,000; was set to 17,​500). ​ Added the max limits to the encoding options as well: +
- +
-<​code>​ +
---encopts '​keyint=30:​vbv-bufsize=14000:​vbv-maxrate=14000'​ +
-</​code>​ +
- +
-Comparing the x264 settings between a newer and older file, the only other change made was ''​filler''​ is set to 0. +
- +
-==== dlna-usb-4 (created 2014-07-26) ==== +
- +
-Same settings as above, but reverted HandBrake version back to upstream'​s 0.9.9 release, but without the Gentoo ebuild so that I can have support for closed captioning. +
- +
-Changed the ''​vbv-bufsize''​ and ''​vbv-maxrate''​ to 1024k. +
- +
-==== dlna-usb-5: working spec ==== +
- +
-Drops the specification requirement for a specific bitrate, but now requires two-pass encoding. +
- +
-Drop the vbv-maxrate setting. ​ See [[http://​forum.doom9.org/​showthread.php?​t=147460|this doom9 thread]] for a good explanation on the matter. :) +
- +
-  * HandBrake 0.10.0 (beta3 or newer) +
-  * libdvdread 5.0.0 +
-  * libdvdnav 5.0.1 +
-  * libdvdcss 1.3.0 +
-  * direct AC3/DTS copy +

-  * libav 9.14+
