Below are the steps I took to install ffmpeg, ffmpegthumbnailer, and heroku to use with carrierwave-video and carrierwave-video-thumbnailer gems on my heroku app. I found there was no documentation to do exactly this, so I hope this is helpful for other people (and will save them the countless hours it took me to finally get it to work)
- carrierwave-video gem: https://github.com/rheaton/carrierwave-video
- carrierwave-video-thumbnailer gem: https://github.com/evrone/carrierwave-video-thumbnailer
These are the libraries you will end up installing to get all of this to work.
