• Running ffmpeg in Docker environment on AWS EC2 [duplicate]

  5 mai 2024, par must

  I want to use FFMPEG inside my Java application.
I want to instal ffmpeg in environment where this app is running.

  


  My current Dockerfile :

  


  # Stage 1: Build the application
FROM maven:3.8.4-openjdk-17 AS build
WORKDIR /app
COPY pom.xml .
COPY src ./src
RUN mvn clean install -Dmaven.test.skip=true

# Stage 2: Run the application
FROM openjdk:17
WORKDIR /app
COPY --from=build /app/target/application.jar ./app.jar
EXPOSE 8080
CMD ["java", "-jar", "-Dspring.profiles.active=pr", "app.jar"]


  


  I simply built a docker image by running docker buildx build --platform linux/amd64 -t repo/app:1.0 .

  


  Then in AWS Console I run docker run and pull built image.

  


  Everyone writes about adding

  


  RUN apt-get -y update && apt-get -y upgrade && apt-get install -y --no-install-recommends ffmpeg


  


  but I cannot do it as I'm building image on MacOS and I do no have apt-get command.

  


  When I was trying to pull some image form DockerHub FFMPEG could not be found.

  


  I tried this one : https://hub.docker.com/r/jrottenberg/ffmpeg

  


  and declared DockerFile as :

  


  # Stage 1: Build the application
FROM maven:3.8.4-openjdk-17 AS build
WORKDIR /app
COPY pom.xml .
COPY src ./src
RUN mvn clean install -Dmaven.test.skip=true

# Stage 2: Install ffmpeg
FROM jrottenberg/ffmpeg:latest AS ffmpeg

# Stage 3: Run the application
FROM openjdk:17
WORKDIR /app
COPY --from=build /app/target/application.jar ./app.jar
COPY --from=ffmpeg /usr/local/bin/ffmpeg /usr/local/bin/ffmpeg

EXPOSE 8080
CMD ["java", "-jar", "-Dspring.profiles.active=pr", "app.jar"]


  


  but still it did not work. I get :

  


  ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory


  


  I'm using Amazon Linux on EC2.

  


  Can someone get me on the right track ?

  


• Remux video file and get the output bytes on the fly

  22 septembre 2014, par Miguel Botón

  I have been looking for a solution too many hours and maybe I didn’t use the proper keywords to find it but I give up. I hope somebody can help me with this.

  My goal is to create a small C code that remux a video file to another container (mp4 or whatever, not decided yet) and create a JNI interface to read the raw output bytes in my Java application.

  Create the JNI interface is not a problem and remux the video is pretty simple (and there is a great example at http://ffmpeg.org/doxygen/trunk/doc_2examples_2remuxing_8c-example.html), but I’m having a headache trying to figure out how I can tell FFmpeg to deliver the data when my application requests it.

  I was thinking in create a thread, where the remux would be done, and write the output data to a buffer where my application would read it. When the buffer is full the remux would be paused until it is flushed, but I don’t know how I can achieve that or if it would be a proper solution.

  I believe the best solution will involve creating an AVIOContext but I’m not very sure.

  Thank you very much in advance.

  EDIT :

  A solution I found, but I don’t like it at all, is to run the "ffmpeg" executable, tell it to write the output to "stdout" and read this output from my Java application using an InputStream.

• Asp.net core and react web app video streaming using ffmpeg

  11 février 2021, par noy ezra

  I want to play a live video stream in my web application using ffmpeg. I'm using asp.net core framework on the server-side and react on the client-side. The video stream comes from another application using its IP and port. I've tried using fluent-ffmpeg and failed.
I would really appreciate your help.
Thanks
