I want to use FFmpeg from an NVidia Docker over EC2 AWS machine, and I have some issues.
- I tried using nvencinfo and nvdecinfo in order to get the supported formats, and found that the g3 machine only supported HW decoding for videos using the nv12 format. Do other machines support other, more common formats? If not, is there some kind of best practice for converting videos to this format, and how much of a performance improvement can we expect HW decoding to provide here (if at all)?
- I want to use FFmpeg 4 or newer, which comes as an apt package only on Ubuntu 19.04 or higher - version 18.04 and older have version 3 of FFmpeg. I've tried and failed to update the NVidia Docker to Ubuntu 19.04 - is this supported, or can I expect support for that version any time soon?
