Client examples: OS_COMMAND_AUTOTEST_APP

description

Implementation of EL_VIDEO_TO_MP3_COMMAND_I interface Does AAC -> MP3 audio conversion

notes

Before 2015-10-21 was using piped command:

-f wav - | lame --silent --id3v2-only --tt "Title" -h -b ${bit_rate} - $output_file_path

This was to prevent a problem of incorrect durations being reported in some media players (Neutron MP). A ID3 2.3 title is added to ensure a skelton ID3 header is in place.
