the best suited precompressor for an input file?

[aswadd]

Hi , I already know precomp , antiz , reflate , pzlib ..
my question is if i have an input file & I want to choose the best suited one for the file what can i do ?
For ex :
precomp has the ability to compress mp3 , jpg .. etc
antiz doesn't have this option , reflate i don't know if it has or not ... speed of antiz is good compared to others but precomp can compress jpg / mp3 / png .. etc
so my purpose is if the input has images & not contain mp3 i'll use precomp 038 & if has mp3 so i'll use last version & if not has mp3 // images i'll use other precompresor

so how can i detect if this file has mp3 streams or even a jpg images without testing on all precompressors ?? is their a tool that can detect this ??
& Is is possible to use antiz + packjpg , mp3 compressor to achieve the same result of precomp ??
