ghettorecorder 3.1

Inet radio grabber

GhettoRecorder

Grab hundreds of radio stations simultaneously.

Overview

This repository shows the source code of a multiprocessor capable recorder app.

A documented example runs on my eisenmp framework.

• Class implementation init.py allows external modules (e.g. blacklist) to manipulate instances
• Blacklist module ghetto_blacklist.py JSON records can be merged with my EisenRadio DB dump
• Threaded HTTP server main.py is switching the Backend and feeds the Frontend to run a show
• AAC files cut from stream are repaired on the fly with my aacRepair

Import

from ghettorecorder import GhettoRecorder

ghetto_raid = GhettoRecorder(radio, url)  # use different URLs to test SSL
ghetto_raid.com_in = mp.Queue(maxsize=1)  # eval exec communication
ghetto_raid.com_out = mp.Queue(maxsize=1)  # response; exec ok is "None"
ghetto_raid.audio_out = mp.Queue(maxsize=1)  # current HTTP response buffer
ghetto_raid.start()  # wants a loop in main() to keep the show alive

Snapcraft package

$ sudo snap install ghettorecorder

Desktop icon for the click addicted.

$ ghettorecorder.url  # Ghetto HTTP threaded server
$ ghettorecorder.cmd  # command line with menu

Python package

$ pip3 install ghettorecorder

$ pip3 show ghettorecorder  # prep removal

Configuration File

'Settings.ini' is the config file for GhettoRecorder. INI files consist of sections to divide different settings.::

[STATIONS]
anime_jp = http://streamingv2.shoutcast.com/japanimradio-tokyo

[GLOBAL]
blacklist_enable = True
save_to_dir = f:\54321

[STATIONS] custom radio name and radio connection information (can be pls or m3u playlist)

[GLOBAL] blacklist status and the custom parent directory location

Change parent record path Menu

option 'Change record parent path'
1 -- New parent path for recorded radios. Write to config.
2 -- Back to Main Menu
Enter your choice: 1

    Write a new path to store files
..settings.ini [GLOBAL] section: {'blacklist_enable': 'True', 'save_to_dir': 'f:\\31'}
Enter a new path, OS syntax (f:\10 or /home ) -->:

The default path is the directory of the module. In most cases you want to store grabbed files somewhere else.

Blacklist Menu

Write a new blacklist option to settings.ini file
..settings.ini [GLOBAL] section: {'blacklist_enable': 'True', 'save_to_dir': 'f:\\31'}
1 -- blacklist on (don't write title if already downloaded)
2 -- blacklist off
3 -- Back to Main Menu
Enter your choice: 1

	blacklist is ON: settings.ini file
	Existing titles are not recorded again and again.
file name is "blacklist.json" in the same folder as "settings.ini"
..settings.ini [GLOBAL] section: {'blacklist_enable': 'True', 'save_to_dir': 'f:\\31'}
Hit Enter to leave -->:

Blacklist writing can be switched on/off.
Titles are listed for each of the radios and can be deleted to 'unlist' them.
File name is ``blacklist.json`` and always in the same folder as 'settings.ini'.

Set path to config

Write Path to settings.ini and blacklist.json file
Enter a new path, OS syntax (f:\10 or /home ) -->: F:\44
	created: F:\44
..settings.ini [GLOBAL] section: {'blacklist_enable': 'True'}
Hit Enter to leave -->:

You can store your config file 'settings.ini' somewhere on the file system.
Default place for grabbed files is the mentioned folder.
If a custom save path is written to config, this path is used.

aac file repair

Write a path to aac files. Only aac files will be touched.
..settings.ini [GLOBAL] section: {'blacklist_enable': 'True', 'save_to_dir': 'f:\\31'}
Enter a path, OS syntax (f:\10 or /home ) -->:f:\6aac
	created: f:\6aac
	f:\6aac\aac_repair created
[ COPY(s) in f:\6aac\aac_repair ]
----- 1 file(s) failed -----
f:\6aac\Sergey Sirotin & Golden Light Orchestra - Around The World.aacp
ValueError non-hexadecimal number found in fromhex() arg at position 5438113
----- 97 file(s) repaired -----
f:\6aac\111_Slovo_Original_Mix.aac; cut(bytes): [330]
f:\6aac\351 Lake Shore Drive - You Make My Day.aacp; cut(bytes): [389]

The repair option uses a folder name as input.
Repaired files are stored in 'aac_repair' sub folder.
Cut bytes count is shown at the end of the line.
Repair can fail if the file is corrupted not only at start or end.
