Version of FFmpeg to use? #5

Open gaviriar opened 6 years ago

Hi There,

I have a quick question. What version of FFmpeg was used to build this repo?

I am currently on ffmpeg 2.8 installed via apt and I cannot build it. The missing interfaces are present in ffmpeg 3.4 is that the version that should be used?

jkuri commented 6 years ago

yes, at least version 3.4 is required, preferably 4.0 if possible.

Ok, cool thanks for the clarification. I will test it out with version 3.4 and let you know. Might be worth leaving a note of the version dependency somewhere in the README.md or maybe setting the version in the CMakeLists.txt when looking for the module?

In case anyone else is facing this problem on Ubuntu 16.04 and needs to upgrade to version 3.4 here is how I did it:

sudo add-apt-repository ppa:jonathonf/ffmpeg-3
sudo apt update && sudo apt upgrade

no problem. other option, if running some old version of distro, would be to run inside docker container using ubuntu:bionic image and apply --device /dev/video0 parameters to docker run command.

Ok, thanks I guess that can be another option. Although I would prefer not having to have to run a docker container to be honest. But will definitely keep it in mind. Thanks!
