That was one of the points I listed. If we start adding support for
AC3, DTS, MP3, AAC, we will never cease updating these files. I would
be better to signal that the format is ENCODED, meaning all the bytes
to usec conversions used for PCM do not apply, and have a second
structure that would list the type and possibly contain some
parameters required by the decoder.
It looks like my main patch was not published since it's slightly over
the size limit. I did make a lot of changes in the
module-bluetooth-device code, not sure how I can break those in
pieces. Does anyone have admin rights to let it through?
