## download ffmpeg
https://ffmpeg.org/
Or:
https://raw.githubusercontent.com/fashare2015/gradle-screen-record/master/ffmpeg

### Set ffmpeg path
If you just **download** the ffmpeg instead of **installing** it, **you must set the path of it**.
Add the path of ffmpeg this way:

Config in **rootProject/gradle.properties**:
>FFMPEG_PATH=XXX

**For example:** 
FFMPEG_PATH="./ffmpeg"
