I run Ubuntu 14.04 LTS.
I want to record output from a digital decoder to disk so that it can be watched later on.
Just to clarify the matter; instead of displaying, or while displaying, the output from the decoder on a TV screen, I want to record what is being output from the decoder in mp4 or avi format.
My question is: Does any software exist that will run on Ubuntu that will do the recording? What hardware will be have to be used with the software to enable the software to record the decoder's output?
What I am wanting to do is not the same as the question on "Record Live Streaming - cmks" which is streaming from a website. I'm wanting to record what a decoder is receiving from a satelite and sending to my tv via HDMI or RCA cables.
I found this hardware on eBay that will most likely do the job. All the items are sold with software for Windows. I'd like to avoid using Windows.
Many thanks for any help I can get.
