Hi all,
I am still working on fixing the Soundsource API to read float samples but
I am still stuck on a few things. So far I have sucessfully changed all the
read methods to deal with CSAMPLE instead of SAMPLE as well as changed all
the callers so that the code could compile and I know that I must call
SampleUtil::convert inside each of the soundsources read methods but what I
don't understand is what exactly I'm checking for to decide if I use or
don't use SampleUtil::convert. For example in soundSourcemp3.cpp to my
understanding when an mp3 is dragged into Mixxx the actual file is the
variable m_file. So when I call read I must check some property of m_file
to see if it is actually a float or an int mp3 file and then call
SampleUtil::convert if it is an int. Unfortunately I am not sure what this
property of m_file is. Also since my read now looks like this:
unsigned SoundSourceMp3::read(unsigned long samples_wanted, const CSAMPLE *
_destination)
Even if I did know what property to check and the to call
SampleUtil::convert was needed I still don't know what I would use as the
const SAMPLE* pSrc for the SampleUtil::convert method because since my read
takes CSAMPLES now I would need some part of m_file to be of type SAMPLE?
If anyone can clarify some of this it would be highly appreciated.
Thanks,
James Fagan
