"reverted: FFMpeg "optimizations" from r15517 under linux. -DRUNTIME_CPUDETECT causes high CPU usages and stuttering with upscaling enabled. -O3 is enabled by FFMpeg by default."
Seems -O3 isn't needed in configure for that.

I just checked and ffmpeg is built entirely with -O3 as per default ffmpeg configure (it is disabled with the --disable-optimizations configure flag).

I'll re-compile and dump a logfile.
While it was compiling last night, I was sure I saw some
ff<blah>.c ....... -O0 ........
in the output, which caused me to post the message.
If I get proof from my compile I'll post the log.
Configure definitely was not run with --disable anything, I run it completely without options.
