Battlestar Galactica ripping. At the time I created this git repo, this was by far the most sophisticated set of tools I'd developed. It uses some of the scripts from the parent dir and adds some of its own. smart-encode.sh is the main script, which does several things.

The overall goal of this script is to be an idempotent "transcode the entire series" script. That means it has to know how to encode every single file ripped from the blurays and that when a file is done, it doesn't try to process it again.

NOTE: The files this deals with had already been named according to season and episode! The script doesn't actually deal with the raw, ripped files. Maybe I could figure out the translation between the two by ripping them all again and running checksums against both sets of files.

To accomplish this, the script generally does the following things:

1. Scans a directory for all raw mkv's ripped from the BSG blurays.

2. Processes each mkv serially.

3. Skips the mkv if it's already been processed, noted by the presence of a file named the same as the mkv file in the cache/done directory.

4. Determines the "profile" that fits the file. Profiles are manually created files in data/profiles that set some variables when sourced, giving the script information about which streams to keep and transcode.

5. Determines if the file is interlaced or not.

6. Determines the video quality (x265 CRF) to use for the mkv.

7. Determines a complex_filter chain, if necessary, based on the presence of a file in data/cuts named the same as the mkv being processed. This is how sections of a video get cut out.

8. Runs ffmpeg to transcode the video according to all the factors it's discovered.

9. Writes the ffmpeg output to a file in cache/log named the same as the mkv.

10. Touches the done file in cache/done when it finishes, but only after checking the log output with the done.sh script.

Additional features:

Setting QUALITY=rough makes the script use a faster, lower-quality video encoder and output to the ripping directory instead of the true output directory. This feature lets you more quickly test any video cuts you've made.
