[datatype-dev] Re: CR: Compressed media pipeline (aka f-n-f) decoder support
Sheldon fu sfu at real.comOk. 'datatype/samples/dsp_decoder/cmp' would work. It can not take the 'dsp_decoder' module position because the 'standard' dsp decoder is the 'return dummy PCM data' one as documented on our website. fxd On Mon, 2009-09-21 at 11:03 -0400, Eric Hyche wrote: > You might consider putting it in a "samples/" directory > to be consistent with other samples.
