• Move overlay left to right with specific overlay starting position

  3 décembre 2020, par k0ngoz

  The command below moves image left to right, starting from outside the frame on the left side, with opacity on the image.

  


  ffmpeg -i test.mp4 -i bar.png -filter_complex "[1:v]format=argb,geq=r='r(X,Y)':a='0.5*alpha(X,Y)'[zork];[0:v][zork]overlay=x='if(lte(-w+(t)*100,100),-w+(t)*100,100)':y=0" output.mp4


  


  What I need, is to have the image being full-screen in the beginning of the video, and then slowly moving towards the right side, never completely exiting the frame up right up until the point where the video finishes(image still fullscreen as video ends).

  


  So the tempo has to vary based on the video length, for the image not to exit the frame at neither the start or finishing point.

  


• How to add "ffmpeg" to the Cloud Run environment or to Dockerfile ?

  16 janvier 2021, par awabs

  I am triying to a logo to video that is uploaded to cloud storage using ffmpeg library, I deployed this code as cloud function is runs only with small size videos, so I decided to move to cloud run, but here I have to build container myself so I used this command instead

  


  gcloud builds submit --pack image=europe-west1-docker.pkg.dev/video-sharing-a1mfa/video-sharing-repo/my-image,env=GOOGLE_FUNCTION_TARGET=addLogo


  


  and it builds the image and I just had to create a service in the Cloud Run and it is running, but unfortunately when I trigger this function I get this error

  


  Error: spawn ffmpeg ENOENT
at Process.ChildProcess._handle.onexit (internal/child_process.js:268:19)
at onErrorNT (internal/child_process.js:470:16)
at processTicksAndRejections (internal/process/task_queues.js:84:21)


  


  Which I am not sure of but I guess is that ffmpeg in not installed in contanier (where it comes preinstalled in the gcloud functions env). Any idea how to install it or what the docker file configuration might be ?

  


  here is my code :

  


  const { Storage } = require('@google-cloud/storage');
const projectId = 'video-sharing-a1mfa';
let gcs = new Storage({
    projectId
});

const os = require('os');
const path = require('path');
const spawn = require('child-process-promise').spawn;


exports.addLogo = async (req, res) => {

const event = JSON.parse(req.body);
const bucket = event.bucket;
const contentType = event.contentType;
const filePath = event.name;

console.log('File change detected, function execution started');
if (path.basename(filePath).startsWith('resized-')) {
    console.log('We already renamed that file!');
    return;
}
const destBucket = gcs.bucket(bucket);
const tmpFilePath = path.join(os.tmpdir(), path.basename(filePath));
const metadata = { contentType: contentType };
const tmpLogoPath = path.join(os.tmpdir(), 'watermark.png');
await destBucket.file('watermark.png').download({
    destination: tmpLogoPath
})

const newPath = path.join(os.tmpdir(), 'output.mp4')

await destBucket.file(filePath).download({
    destination: tmpFilePath
});
console.log('file downloaded to temp');

console.log('adding watermark');

var str = "overlay=10:10"

await spawn('ffmpeg', ['-i', tmpFilePath, '-i', tmpLogoPath, '-filter_complex', str, newPath]);


console.log('watermark added');

return destBucket.upload(newPath, {
    destination: path.dirname(filePath) + '/resized-' + path.basename(filePath),
    metadata: metadata
});;
};


  


• "ff_check_interrupt" is not adding in the ffmpeg build

  I have been trying to corss-compile ffmpeg with the following configuration.

  But the generated libavformat.so file doesn't include the ff_check_interrupt method and results in

  


  


  undefined reference to 'ff_check_interrupt'
