[Mplayer-users] Speed increase when quieting mplayer output

[André Dahlqvist]

I was just doing some benchmarks on a file that I tested with mplayer about
week ago and I was surprised to see a 0.5 second slowdown. I accepted the
result and went ahead and redirected the benchmark output to the file I
store benchmaks in. When I did that I came back to the performance I had
seen last week and I realized it was because off less text output in my
xterm. I then remembered Arpi mentioning exactly that in the DVD playback
thread. I then added the -quiet option to my benchmarks and shaved off
almost half a second:

mplayer -vo null -vc ffdivx -nosound -benchmark -frames 1000 | grep BENCH > bench.txt

BENCHMARKs: V:   4.681s VO:   0.008s A:   0.000s Sys:   0.694s =    5.382s
BENCHMARKs: V:   4.672s VO:   0.008s A:   0.000s Sys:   0.697s =    5.377s
BENCHMARKs: V:   4.672s VO:   0.008s A:   0.000s Sys:   0.694s =    5.375s

mplayer -vo null -vc ffdivx -nosound -benchmark -frames 1000 -quiet | grep BENCH > bench.txt

BENCHMARKs: V:   4.553s VO:   0.007s A:   0.000s Sys:   0.348s =    4.909s
BENCHMARKs: V:   4.551s VO:   0.007s A:   0.000s Sys:   0.347s =    4.905s
BENCHMARKs: V:   4.555s VO:   0.007s A:   0.000s Sys:   0.346s =    4.908s
