I have used MythTV for a number of years, having migrated from Freevo, recording Freeview television and radio programmes to watch or listen to.
To listen to radio programmes recorded by MythTV on a smartphone requires a conversion of the recorded .mpg file into a smaller and more transferable .mp3 file.
Mythweb is used to manage the recordings on the media server. Allowing access from any computer in the house. VLC allows the programme to be watched or listened to. It also allows files to be saved locally. Originating as Television video broadcasts MythTV saves the files are as .mpg. To make the file available for use on a smartphone requires a change of format, which fortunately will also reduce the size of the file.
On the main house computer, running Linux, a conversion program runs daily looking within a directory and converting outstanding files. For convenience it runs at a little after 8pm each evening.
The file located in the downloads folder is called mpg2mp3, with the following content:
#!/bin/bash IFS= for filename in /home/neil/Music/*.mpg do MPGNAME=/home/neil/Music/$( basename "$filename" .mpg ).mpg MP3NAME=/home/neil/Music/$( basename "$filename" .mpg ).mp3 #echo "MPGNAME: " $MPGNAME echo "MP3NAME: " $MP3NAME if [ ! -f $MP3NAME ] then ffmpeg -i $MPGNAME -vn -ar 44100 -ac 2 -ab 192 -f mp3 $MP3NAME fi done
A line in the /etc/crontab file calls the program each day at 8:15pm.
neil@:~$ cat /etc/crontab # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d.
