• dockerfile apt-get install ffmpeg unmet dependencies

  8 juillet 2020, par Martin

  I have a Dockerfile which looks like this :

  


  FROM node:carbon
VOLUME ["/root"]
ADD setup-ffmpeg.sh /root
RUN /root/setup-ffmpeg.sh
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
EXPOSE 8080
CMD [ "npm", "start" ]


  


  Which tries to run the file setup-ffmpeg.sh :

  


  #!/usr/bin/env bash
echo 'deb http://www.deb-multimedia.org jessie main non-free' >> /etc/apt/sources.list
echo 'deb-src http://www.deb-multimedia.org jessie main non-free' >> /etc/apt/sources.list
apt-get update
apt-get install -y --force-yes deb-multimedia-keyring
apt-get remove -y --force-yes ffmpeg
apt-get install -y --force-yes build-essential libmp3lame-dev libvorbis-dev libtheora-dev     libspeex-dev yasm pkg-config libfaac-dev libx264-dev libav-tools 
echo "ffmpeg time"
apt-get install ffmpeg 


  


  I am on Ubuntu 20.04 LTS, and try to run this the Dockerfile, from terminal, with the command :

  


  docker build -t alien35/node-web-app .


  


  This causes an error when reaching the ffmpeg part though :

• launch ffmpeg on Maui Android

  4 décembre 2024, par lolveley

  I have an Maui app which is deployed on an Android tablet, a Samsung tab S9 FE.
I have copied the ARM8 version of the ffmpeg executable in the AppDataDirectory of my deployed app. The executable, named "ffmpeg", has the rights _rwxrwxrwx (the underscore means this is a file, and not a directory).

  


  I try to execute the file with the command Process.Start :

  


  private void GetThumbnail(string inputFile, string imageFullPath, string ffmpegFullPath)
{
        ProcessStartInfo startInfo = new ProcessStartInfo();

        string arguments = $"-i {inputFile} -ss 00:01:00.000 -vframes 1 {imageFullPath}";

        startInfo.FileName = ffmpegFullPath;
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.RedirectStandardError = true;
        startInfo.RedirectStandardOutput = true;
        startInfo.Arguments = arguments;

        try
        {
            Process process = Process.Start(startInfo);
            process.WaitForExit(5000);
            process.Close();
        }
        catch(Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
}


  


  There is an exception saying the access is denied :

  


  


  System.ComponentModel.Win32Exception (13) : An error occurred trying to
start process '/data/user/0/sxb.explorateur.de.fichiers/files/ffmpeg'
with working directory '/data/data/sxb.explorateur.de.fichiers/files'.
Permission denied

  


  


  The error message doesn't say more, and I do not see what to do, the directory usually is dedicated to the application, and the file is executable.

  


  I know that Android has restricted policies with file execution, and maybe it's even harder for the Samsung operating system, namely One UI 6.1.1 and Android 14.

  


  thank you.

  


• Ffmpeg sbs 3d mkv to 3d baked into 2d video

  27 octobre 2020, par goodkid38

  I have a couple of 3d blu-ray rips I'd like to stream to a tv that is not 3d compatible. I have a samsung smart tv with an app that I made to stream the video locally. I'm using ffmpeg on my backend to transcode video. I'm curoius to see if ffmpeg can take a 3d sbs mkv and bake the 3d elements into a 2d image. That way the stream is still 3d even on non-compatible devices.
