Tvheadend

Hi, you're doing an awesome job at configuration & patching ffmpeg, especially getting all the hardware-encodings to compile at the same time is very hard, it's a real shame to only let tvheadend use this; and having multiple different versions with different compile-options/source-version could potentially cause problems when used at the same time.

I would like to request that you add a build-option to also install binarys for ffmpeg/ffprobe/ffplay

(to avoid "colisions" with the system-ffmpeg, installing them under /usr/local or with an alternative name like ffmpeg-tvh might be a good idea)...

Thanks,
