[Flac-users] Extending mp3/ogg application to play flac
...d I have encoded all my "good" CDs into it!
Now I want to extend an existing application able to decode mp3 and ogg
vorbis to replay flac as well. It is a plugin to a set top box
application on Linux (VDR).
The existing code decodes into a mad_pcm structure using mad fixed point

general.
However there are two issues I'm unsure about:
- Do I need to convert the decoded audio data delivered to the
FileDecoderWriteCallback to be compatible with mad_pcm/mad_fixed_t
data?

not sure about the mad_fixed_t format, but probably. all samples
coming out of the FLAC decoder are linear PCM 32-bit signed ints.
e.g. a sample from CD audio will be in the range -32768 (0xFFFF8000)
to 32767 (0x00007FFF)
