When you want to speed up Enconding mpeg2enc (which it was never built for) A small speedup should be able to gained when you change the options of mpeg2enc to this: -M 8--video-bitrate 20000 --video-buffer 1000 -f 0 -4 4 -2 4 -r 8 -D 8 -o ... The encoding time did go down a little on my machine from 37-39 sec down to 35.5-37 seconds. Measured with time, using several tries. The problem ist that the original developer of mpeg2enc has been offline for a lot of years. If you find things to speed up...
Minor fixes to the build system. Some small speed improvements
