Hi,

i have written an opcode to playback ogg files using libogg. Nothing too 
fancy at the moment - it will not resample when the sr of the orc is 
different then the one of the ogg file nor does it take possible 
bitstream changes in the ogg stream into account. But it does play ogg 
files fine on my machines.

My question is  - is it fine if I put it in Opcodes and add an entry 
similar to the udp opcodes in SConstruct (note that it adds libogg to be 
linked against )?

Best,
    Simon

I am not very happy about adding a special opcode to play OGG.  This 
shoudl be done through libsndfile, and adding an extra opcode seems 
confusing and unnatural.  Why not use -i "ogg123 - foo.ogg" ?

Has this been done? From the last discussion about ogg vorbis in csound 
I thought that this is still an open issue?

Why not use -i "ogg123 - foo.ogg" ?

Is this the correct syntax? And then read in an orchestra with ins 
opcodes and company? Why I thought of an opcode was that I want to be 
able to play back several ogg files at the same time using the 
api/python bindings. I am not happy what I can do with gstreamer and 
sdl_mixer both are able to play back ogg files from within python but 
are quite cpu intensive.

Best,
    Simon

Sorry -- typo -- syntax is -i "|ogg123 - foo.ogg"

We are waiting for a coding expert to implement OGG in libsoundfile,
which is said to have some problems
