  • Conversion of .dav [Ubuntu]

    3 juin 2018, par Dauas

    I’ve installed ffmpeg on a Ubuntu Linux Amazon EC2 Server and have a Lorex FLIR NVR directly FTP transferring .DAV files to it. In this system a Java program would then tell the EC2 to convert the .dav to but this is where the problems begin, FFMPEG fails to convert the .dav file and to my surprise there is no Codec for .dav (Though I see mention of it once having been supported). I reach out for a solution to this File Format problem, unfortunately the .dav files are a given as the NVR I have is incapable of transfering any other data type over the web, but what is the best way to convert a .dav file on a linux machine ? My Java program has full access to the Shell. It would also be incredibly helpful if anybody were to know how to get their hands on a .dav codec I could test with ffmpeg. I very much value all of your time helping me on this issue.

  • Compiling FFMPEG on CentOS DigitalOcean

    29 juillet 2015, par coder_uk

    I set up a DigitalOcean instance running CentOS 6.5 and successfully followed the guide to compile FFMPEG (https://trac.ffmpeg.org/wiki/CompilationGuide/Centos). Hurrah !

    But of course I realised that by default, DigitalOcean creates a root user and so ffmpeg now lives in /root/bin/ffmpeg. Which isn’t ideal because when I want to exec the ffmpeg bin from nginx, I would have to run nginx as root for it to have permission.

    Questions ...

    1) Long-shot, but presumably if I change the owner of the ffmpeg binary to nginx, it still won’t work, because nginx won’t be able to access the /root folder it is in. Correct ?

    2) I could run nginx as root (’user root’). But this seems like a very bad idea. Correct ?

    3) Which leaves me with the option of creating a new user, and then compiling ffmpeg into its home folder. But : which user ? EC2 creates ’ec2-user’, so should I make my own equivalent for DO ? But then won’t I have to run nginx as that user, else I’ll run into the same problem ?

    Or should I compile ffmpeg into the ’nginx’ home folder, if indeed it has one ? Is that how it is supposed to be done ?

    Since compiling ffmpeg takes ages, I don’t want to keep doing it, and the static files all seem very out of date. Thanks
