Running ffmpeg in Docker environment on AWS EC2 [duplicate]
5 mai 2024, par mustI 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 ?

Extracting Thumbnail URL from Video URL
29 août 2023, par Deepak SangleSo, I have a video URL in an Amazon S3 bucket. I must extract the thumbnail image (preview image) from the video URL. The catch is that I do not have the luxury to download or upload the complete video since it takes time. My approach is something like this.
I first created a blob object containing the first few seconds of that video using something like this.


const chunkSize = 1024*1024; // 1MB
 const start = 0;
 const end = chunkSize - 1;
 const rangeHeader = `bytes=${start}-${end}`;
 
 const VideoResponse = await axios.get(url, { 
 responseType: 'arraybuffer',
 headers: { Range: rangeHeader }
 });

 const chunkData = VideoResponse.data; 
 
 const videoBlob = new Blob([chunkData], { type: 'video/mp4' });
 const videoUrl = URL.createObjectURL(videoBlob);
 console.log({chunkData, videoBlob, videoUrl});



Console gives me something like this


{
 chunkData: <buffer 00="00" 1c="1c" 66="66" 74="74" 79="79" 70="70" 6d="6d" 34="34" 32="32" 69="69" 73="73" 6f="6f" 61="61" 76="76" 63="63" 31="31" 02="02" bd="bd" ab="ab" 6c="6c" 68="68" 64="64" c7="c7" 1048526="1048526" more="more" bytes="bytes">,
 videoBlob: Blob { size: 1048576, type: 'video/mp4' },
 videoUrl: 'blob:nodedata:764fce87-792f-47e8-bc3e-15921ee5787f'
}
</buffer>


Now, there are many options after this. I am trying to download this blob object by converting it into a file. After I successfully convert it into an mp4 file, I can easily take a screenshot of it using
fluent-ffmpeg
package. However, I couldn't convert it into a file. If I try to do something like this

const BlobResponse = await axios({
 method: 'GET',
 url: videoUrl,
 responseType: 'stream'
 });

 const file = fs.createWriteStream(`video.mp4`);
 BlobResponse.data.pipe(file);
 
 file.on("error", (error) => {
 console.log(`There was an error writing the file. Details: $ {error}`);
 });

 file.on('finish', () => {
 file.close();
 console.log("File downloaded successfully");
 });



But it throws me the error
AxiosError: Unsupported protocol blob:


I also tried to directly convert the blob object to a jpeg object but to no avail.


I have searched complete StackOverflow, and I have not found a single solution working so please let me know why those are not working or if there is any new solution to do this.

java.lang.NoClassDefFoundError : Could not initialize class on Linux (Works fine on Windows)
26 décembre 2016, par Jake MillerI’m using a C++ FFmpeg wrapper for Java (org.bytedeco.javacpp). This works perfectly on a Windows machine (my development machine) but throws this error when ran on Linux (Amazon Web Services Elastic Beanstalk) :
java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil
at java.lang.Class.forName0(Native Method) ~[na:1.8.0_111]

at org.bytedeco.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.java:385) ~[javacv-1.3.jar!/:1.3]
</clinit>I’ve been troubleshooting for the past 2 days and have tried the following to fix the issue :
- upgrade to Linux to 2.4
- downgrading javacpp to 1.2.1
- running mvn clean
- running mvn -U
- deleting contents of /.m2/ and redownloading dependencies
- various combinations of dependency versions
- git clone on a Linux VM & running mvn install there
When looking further into the issue, I stumbled upon documentation for
avformat$AVFormatContext
as it’s in the stack trace posted above (6th line). The documentation for a C++ class namedAVFormatContext
. Whenever I attempt to view the class in Eclipse, it saysSource Not Found
.My question : could this problem possibly be caused by the C++ libraries on my Linux VM ? None of the above solutions fixed it so this is my only hypothesis as of now.
Here’s my other Stack Overflow question regarding this subject : Java.lang.NoClassDefFoundError caused by FFmpeg when deployed on Linux as a packaged .war (Works on development machine)
