[FFmpeg-user] force/replace colors of waveform (showwaves)? (and 60fps at 720p)?

Sun Apr 20 12:54:41 CEST 2014

working command im using is below, generates a nice output like

http://dsfm.tv/images/showwaves.png

white and grey seem to be the 2 colors generated for the waveform. 

is there any way to change these colors?

-----------------------

also... when -r 60 is specified before -filter_complex, the output is 60 fps, but showwaves still only outputs at 34fps (@720p)(even if r=60 is specified in the filter_complex), but if i change to showwaves=s=720x405, showwaves outputs a proper 60fps... 

not sure at what point showwaves decides to not try for 60fps anymore, but id like to avoid generating a smaller sized true 60fps file, and then scaling the rest of the way to reach my target of 720p... any ideas?

----------------------- 

console stuffs:

ffmpeg -i http://domiain.com:8000 -filter_complex showwaves=s=1280x720:mode=line -c:v libx264 -preset superfast -b:v 4096k -pix_fmt yuv420p  -c:a aac -strict -2 -b:a 256k -f mp4 outies.mp4
