INSTRUCTIONS FOR UBUNTU 18.04 LTS

Ubuntu+Win compatible version was tested on Linux Ubuntu 18.04 using Wine 5.0 (WineHQ).

• First of all, extract all zip contents to a folder, like /Home/user_name/FFBatch_215.

• FFmpeg Batch performance is similar to a Windows installation, though interface is not perfectly cloned,
  and some features are missing, like automatic shutdown. Application can fail if resolution is changed during execution.

• Playonlinux does not seem to work well with FFmpeg Batch.

Follow instructions, be careful to use your current ubuntu version:
