Why does fluent-ffmpeg only work when it throws the error Output stream closed
29 mars 2024, par volume oneI am using fluent-ffmpeg to process a video file (and then upload that to Amazon S3). The code is very straightforward but it only works if :


- 

- pipe option
{end: true}is set in.output() - which has a side-effect that causes the following console log output








Processing : 19.261847354642416% done Processing :
32.365144874807335% done Processing : 48.80978326261429% done Processing : 78.35771917058617%
Processing : 91.49377493455148% done Processing :
99.91264359125745% done An error occurred : Output stream closed




Despite that error, it seems the file is generated correctly and it gets uploaded to Amazon S3 fine.


This is the fluent-ffmpeg code :


import {PassThrough} from 'node:stream';
import FFMpeg from 'fluent-ffmpeg';

let PassThroughStream = new PassThrough();

 FFMpeg('/testvideo.mp4')
 .videoCodec('libx264')
 .audioCodec('libmp3lame')
 .size(`640x480`)
 // Stream output requires manually specifying output formats
 .format('mp4')
 .outputOptions('-movflags dash')
 .on('progress', function (progress) {
 console.log('Processing: ' + progress.percent + '% done');
 })
 .on('error', function (err) {
 console.log('An error occurred: ' + err.message);
 })
 .on('end', function () {
 console.log('FFMpeg Processing finished!');
 })
 .output(PassThroughStream, {end: true})
 .run();

 // Now upload to S3
 try {
 await s3Upload({
 AWSS3Client: 'mys3client',
 Bucket: 'publicbucket,
 ACL: "public-read",
 ContentType: 'video/mp4',
 Key: 'whoever/whatever.mp4',
 Body: PassThroughStream
 });
 } catch (error) {
 console.log(`s3Upload error`, error)
 }


If I set the pipe
output()option to{end: false}then there is no error from fluent-ffmpeg and I get"Processing: 100% done FFMpeg Processing finished!"as the final console log.

BUT the problem is that the
s3Upload()does not do anything. There are no errors. Just no activity.

I feel very uncomfortable letting
fluent-ffmpegend in an error even if the code itself does the job intended. It will also cause testing to fail. What could be the issue ?

The command line code is :
ffmpeg -i https:/xxxbucket.s3.amazonaws.com/14555/file-example.mp4 -acodec libmp3lame -vcodec libx264 -filter:v scale=w=trunc(oh*a/2)*2:h=480 -f mp4 -movflags dash pipe:1

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 runand 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-getcommand.

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 ?

Live stream doesn't seem to be passed to AWS correctly
12 août 2024, par NoobAmII'm trying to stream my live video into Amazon IVS and I don't see it on the live channels.


Is it possible I have a mistake in my FFMPEG configuration ?
I'm expecting to see this in my playback url or on the console screen for playback but I see nothing at the moment.


As I understand it, shouldn't I see some kind of playback in the live channels if a stream is being sent that channel ?


` async sendDataToIvs(channelArn: string, payload: any): Promise<void> {
