a2dpconf(1) General Commands Manual a2dpconf(1)

Name

a2dpconf - Decode A2DP codec capability hex strings

SYNOPSIS

a2dpconf [OPTION]... [CODEC:]CONFIG...

DESCRIPTION

a2dpconf presents the fields of the given A2DP codec CONFIG in a human-readable format. CODEC is the name of the relevant codec, and CONFIG is the hexadecimal encoding of the configuration or capabilities binary "blob" as reported by tools such as bluealsactl(1) or the debug output of bluealsad(8). (see EXAMPLES below).

OPTIONS

-h, --help
Print this help and exit.
-V, --version
Print version and exit.
-v, --verbose
Show verbose bit-stream details. Display each field as a binary mask with each bit represented by a single character.
-x, --auto-detect
Try to auto-detect the codec. If the name of the codec associated with the configuration string is not known, then give this option and the configuration string without the codec name prefix. The output is then a list of all possible known codec configurations for which the given string is valid.
