I've been reading and rereading the documentation, but there are still some
things I am not understanding.
1. pymedia.audio.sound.Output has a format field in its constructor. I
believe that the list of possible values for this field are at the bottom of
the doc page for pymedia.audio.sound. Some of the format designators are
self-explanatory, but others are not. Is there documentation somewhere for
what these constants mean? For example, what is the difference between
AFMT_S16_{LE, NE, BE}? Which one do I use for outputing in ogg?
2. In the audio player example in the tutorial, there is the statement:
In the case when the decoder has enough data to decompress, it'll return Frame
with all essential parameters set. If it returns None, you need to pass more
data to it by reading the file further and passing it to the decoder.
I don't understand how to implement this requirement. If the decoder returns
None, how much more data do we need to pass? What happens if we pass too
much data? In the code from the fully functional example, I don't see where
the code requests more data in an effort to satisfy the decoder and get a
Frame back rather than None. If that code is not there, why is it that the
fully functional example does not implement a requirement specified in the
documentation?
3. Where is the Frame documented? The same fully functional example gets
frames back from the demultiplexor -- these are called "sub stream data" in
other places in the documentation -- and then indexes one of these (fr[0] and
fr[1]). Where is the documentation for these objects? Is there an fr[2]?
4. Is class Player just a higher level way of accessing the play functionality
of PyMedia? If so, is there ever any reason to use the procedures described
in the tutorial for playing? Maybe I don't need answers to the previous
questions if I should just be using Player. If that's true, I wish that the
tutorial had pointed me in this direction.
