• Extracting Thumbnail URL from Video URL

  29 août 2023, par Deepak Sangle

  So, 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

  


  {&#xA;  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">,&#xA;  videoBlob: Blob { size: 1048576, type: &#x27;video/mp4&#x27; },&#xA;  videoUrl: &#x27;blob:nodedata:764fce87-792f-47e8-bc3e-15921ee5787f&#x27;&#xA;}&#xA;</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.

  


• 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 ?
