...re... In working on the parallel version of oggenc (both threaded and MPI), a profiling run shows that the function vorbis_analysis() takes up the majority of the run time. This seems to be an obvious choice for parallelization -- send each vorbis_block to a different processor, and let them call vorbis_analsis() in parallel with each other. However, as has been briefly alluded on this list before, there is global state that is shared between all vorbis_block instances. Specifically, vorbis_block contains a pointer to the stream's vorbis_dsp_state, which in turn, has a pointer to the stream's v...
