I have an application that uses ffmpeg to perform file conversions including 
applying the filter -vf colormatrix=bt601:bt709. I would like to also apply a 
gamma changing filter such as -vf mp=eq2=1:1:0:1:2:1:1:1.

The problem is that the application using ffmpeg (which I can *not* change) 
cannot have commas included in the arguments provided. No combination of 
escapes, quoting, etc will work if there is a comma anywhere in the arguments.

This seems to preclude the possibility of having two filters since as near as I 
can tell, the only way to do so would be

-vf colormatrix=bt601:bt709, mp=eq2=1:1:0:1:2:1:1:1

Is there an alternate method of including two filters that does not involve using a 
comma, or can a filter be "prebuilt" as a text file that I can then include in 
an ffmpeg commandline preset?
