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    Since compiling ffmpeg takes ages, I don’t want to keep doing it, and the static files all seem very out of date.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

  • Converting 2-channel .mov file to .mp3 with ffmpeg

    29 mai 2019, par Josh Earl

    I use Skype Call Recorder to record Skype interviews. The app saves files in .mov format, with 2 audio channels.

    When I submit these files for transcription, they always come back with just one channel transcribed.

    I need to 1.) merge the tracks, and 2.) convert the .mov file to .mp3 format.

    Right now the command I’m working with is :

    ffmpeg -i input.mov -map 0:a output.mp3

    I get the following errors :

     Invalid audio stream. Exactly one MP3 audio stream is required.
    
 Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

    What am I missing ?

    Here’s the full console output, if it helps :

  • ffmpeg stuck in generating thumbnail of video [closed]

    10 décembre 2019, par user6121419

    I’m trying to create a thumbnail of a .mov video with ffmpeg, but it gets stuck.
    I tried the same command on 2 different machines and with different types of arguments, but nothing changed the result. The video itself can be viewed without a problem, so it shouldn’t be corrupted.
    The video was taken on an iphone at 4k 60fps.

    What I’ve tried :

    ffmpeg -i IMG_1001.MOV -ss 00:00:02 -vframes 1 thumbnail.jpg

    It gets stuck at the third last line frame= 0 fps=0.0 q=0.0 Lsize=N/A time=00:00:00.00 bitrate=N/A speed=   0x and from then on, I stopped the process with ctrl+c
