• Docker build dependent on host Ubuntu version not on the actual Docker File

  26 mars 2021, par user8912375

  I'm facing an issue with my docker build.

  


  I have a dockerfile as follow :

  


  FROM python:3.6


RUN apt-get update && apt-get install -y libav-tools 
....


  


  The issue I'm facing is that I'm getting this error when building on ubuntu:20.04 LTS

  


  E: Package 'libav-tools' has no installation candidate


  


  I made some research and found out that ffmpeg should be a replacement for libav-tools

  


  FROM python:3.6


RUN apt-get update && apt-get install -y ffmpeg 
....


  


  I tried again without any issue.

  


  but when I tried to build the same image with ffmpeg on ubuntu:16.04 xenial I'm getting a message that

  


  E: Package 'ffmpeg' has no installation candidate


  


  after that, I replace the ffmpeg with libav-tools and it worked on ubuntu:16.04

  


  I'm confused now why docker build is dependant on the host ubuntu version that I'm using and not the actual dockerfile.

  


  shouldn't docker build be coherent whatever the ubuntu version I'm using.

  


• NVIDIA Version Outdated Error when mine is updated

  21 février 2021, par Agent Merlot

  I'm trying to encode stuff with my NVIDIA GeForce MX150 (Driver Version : 461.09).

  


  import os
os.system(f'ffmpeg -i "Cells at Work Season 2 - Episode 07 - English Subbed.mp4" -c:a copy -c:v hevc_nvenc "07.mp4"')

  


  Whenever I'm trying to run it, I'm getting this error.

  


  [hevc_nvenc @ 0000017a8bdf7e40] Cannot load nvEncodeAPI64.dll
[hevc_nvenc @ 0000017a8bdf7e40] The minimum required Nvidia driver for nvenc is 436.15 or newer
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!

  


  What bugs me is that it says that I need 436.15 or newer, and mine is 461.09. That means it should work, right ? Can anyone help ?

  


• Your FFProbe version is too old and does not support

  19 janvier 2021, par SupunSpera

  I am Using Laravel 8 and ffmpeg to save thumbnail from a video.

  


  


  


    $path = Storage::putFile('public/uploads/videos', new File($data['video']));
        $path_parts = explode("uploads/videos/", $path);
        $video = explode("public/videos/", $path_parts[1]);
        $video_name = $video[0];
        $thumbnail_name = explode('.', $video_name);
        $thumbnail_name1 = $thumbnail_name[0] . ".png";

        $thumbnail = 'public/videos/thumbnails/' . $thumbnail_name1;
        FFMpeg::fromDisk('local')
            ->open($path)
            ->getFrameFromSeconds(5)
            ->export()
            ->toDisk('local')
            ->save($thumbnail);

  


  


  



  I receive this error. Your FFProbe version is too old and does not support.
