GSoC - Theora multithread decoder
....
According to the model that i did (
http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/implementation.pdf<http://lampiao.lsc.ic.unicamp.br/%7Epiga/gsoc_2008/implementation.pdf>)
the decoding time should be reduced in 33%, but it was just 10% for pthread
an 5% for openMP.
I used a video with 1440x1080. The pthread implementation has 3 threads and
the OpenMP was executed with the environment variable OMP_NUM_THREADS=3. The
results are:
Real(s) User(s) System(s)
Speed up(%)
OpenMP 25.2 29.2 1.8
