Bashnapi - napiprojekt.pl client

This script is a NapiProjekt client written in bash. It automatically downloads subtitles from napiprojekt.pl database basing on the video file.

This script works on Linux & OS X systems. It has very limited requirements and is mostly depending on bash (it is proven to run from bash 2.04 - which makes it ideal for embedded devices) and coreutils (which should be available on most modern systems, no Perl or Python is required).

Installation

Bashnapi uses cmake to build itself and install. Typical install procedure is very simple:

$ cd bashnapi
$ mkdir build && cd build
$ cmake ..
$ make && make install

Installation on embedded devices

In case you want to install bashnapi on a host which doesn't have CMake, the procedure is very similar. Just install to a local directory and deploy that to your device. Below is an example:

$ cd bashnapi
$ mkdir build
$ cmake -DCMAKE_INSTALL_PREFIX=napi_install -DNAPI_INSTALL_PREFIX=/opt/napi ..
$ make && make install

bashnapi is now installed in the napi_install directory on your local machine. Just deploy that to your device (with scp, ftp, or whatever you prefer) and add the path to a directory under /opt/napi/bin to your PATH. The variables:

- `CMAKE_INSTALL_PREFIX` - defines the directory on the host to which napi
will be installed

- `NAPI_INSTALL_PREFIX` - defines the directory on the target to which napi
should be deployed

You can use any directory names, napi_install and /opt/napi have been picked arbitrarily without any strict reason.

Dockerized application

napi.sh is available as well as a Dockerized application. In order to use it with docker, just build the container image:

$ docker build -t napi .

Once it's built it can be used through docker:

$ docker run -v /media:/mnt -it napi scan /mnt

The above command maps the directory /media to a directory /mnt in the container and invokes napi.sh scan action in container's /mnt.

Actions

Script functionality has been divided into actions. Each action implements a specific request type. Available actions:

• scan - scan a directory (or a single file) and download subtitles for all found video files,
• download - download subtitles using a "dc link"
• search - search for a movie
• subtitles - list subtitles for given movie

Each action has its own command set and its own help system as well so,

 $ napi.sh scan --help

... and

$ napi.sh download --help

... will produce different output. Try out help for different actions to learn about how to use them and what do they do. Generic options, shared by all actions are listed in the global help:

$ napi.sh --help

Below are some usage examples

scan action

This action is the equivalent of napi 1.X versions behaviour. It goes either through given directories or media files and, creates a media file list and tries to download subtitles for all found media files.

Examples:

• Download subtitles for video_file.avi:

  $ napi.sh scan video_file.avi

• Iterate through all elements in current directory and try to download subtitles for them. If directory contains subdirectories - than the script will also iterate through all the files in subdirectories:

  $ napi.sh scan *

• Try to find and download subtitles for all files in movie_dir/ directory:

  $ napi.sh scan movie_dir/

• This will recursively search for video file in directories like:

  $ napi.sh scan dir1/ dir2/ dir3/ dir_other/

• It has file size limitation too ! Download subtitles for all supported video files which are bigger than 100 MB:

  $ napi.sh scan -b 100 *

• Not to mention that it integrates a separate subtitles converter written completely in bash & awk. To download subtitles for all supported video files and convert them to subrip format on the fly, just use the -f option:

  $ napi.sh <action> -f subrip *

download action (experimental)

This action can be used to download a selected subtitles from napiprojekt.pl using the subtitles id, which can be obtained from napiprojekt.pl site.

• Download subtitles having its hash/id:

  $ napi.sh download napiprojekt:06aec10a749a68403613b2af8b2c4db8

search action (experimental)

This action can be used to search for a given movie in napiprojekt.pl database.

• Search for movie "terminator":

  $ napi.sh search -k movie terminator $ napi.sh search "the big bang theory"

subtitles action (experimental)

This action can be used to list all the available subtitles for a given movie title. It accepts the url to the movie page, typical work flow is as follows:

$ napi.sh search -k movie "lord of the rings"

The last call has returned a set of napiprojekt subtitles identifiers which can be directly used to get subtitles:

$ napi.sh download napiprojekt:1e81de9b83485336d2821d8dcfefb8bd

You can specify more than one hash/id at once as well:

$ napi.sh download napiprojekt:51f8741fc142f3ed80313544c728d9d4 napiprojekt:ee4096dce1902ea5f985dc929c9a8479

subotage.sh

subotage.sh is a simple subtitles format converter bundled with napi.sh

Currently supported formats:

• mpl2
• tmplayer (most of the versions)
• subrip
• subviewer
• microdvd

Usage

The properly convert from/to microdvd format (or any other format based on frames) a valid information about input/output file frame rate is needed! The default value (if not specified in the command line) is 23.98 fps for input/output.

Examples:

• Convert from microdvd 23.98 fps to subrip. Subrip is default output format so it doesn't have to be specified. The input frame rate is also equal to the default one, so no addition specification in the command line has been made.

  $ subotage.sh -i input_file.txt -o output_file.srt

• Convert from microdvd 25 fps to subviewer:

  $ subotage.sh -i input_file.txt -fi 25 -of subviewer -o output_file.sub

• Convert from subrip to mpl2

  $ subotage.sh -i input_file.srt -of mpl2 -o output_file.fab

• Convert from microdvd 25 fps to microdvd 29.98 fps:

  $ subotage.sh -i input_file.txt -fi 25 -fo 29.98 -of microdvd -o output_file.txt
