FFmpeg

You need to install and setup FFmpeg or Zencoder for this module to work. I think you are using an old tutorial, the permission you mention is no longer present.

How have you configured the video fields? You need to select Amazon S3 there as well. Can I see your site online?

The purpose of using Amazon S3 is to deliver videos fast, video files generally are big files so when you let your server to to handle it lot of your bandwidth will loose on video files, so it is better to use S3 or some other cloud system for video delivering. With the video module you can either use Amazone S3 or Drupal file system, if you use Drupal file system it will require some advanced configurations.

Do you mind me asking what you set the Upload destionations to?

Under admin/config/media/video/transcoders

I've got FFmpeg / avconv selected

Path to FFmpeg or avconv executable is set to /usr/bin/ffmpeg

I downloaded https://github.com/zencoder/zencoder-php/archive/v2.1.2.zip# and installed to libraries/zencoder

but am still getting the same error message in the Status Report and

I'm also getting the same issue, but I have ffmpeg installed and the location of it is configured in the module, but it still says:

Video transcoder: FFmpeg / avconv	
Missing the transcoder library. Please install FFmpeg in to your server if you intend to transcode or to auto create thumbnails.

I have the same error, when I try to upload local videos
