Save a partial video file locally using NodeJS
25 octobre 2017, par SamiI have a serverless web application that is deployed on
AWS
and I have to take a screenshot from an uploaded video toS3
. I am usingffmpeg
to extract the screenshot but the only drawback is that I have to download the video file first in order to letffmpeg
work with it.
Knowing the fact I am usingAWS Lambda
and I don’t have limits for video length users might upload large files which makesAWS Lambda
to hit the storage limit.
To overcome this I thought of downloading a small chunk of the video and use it withffmpeg
to extract the thumbnail so using theS3.getOjbect
method with range params I was able to download a chunk of the file butffmpeg
couldn’t understand it.
Here is my code :s3.getObject({
Bucket: bucketName,
Key: key,
Range: 'bytes=0-1048576'
}, (err, data) => {
fs.writeFile(fileName, data.Body, error => {
if (error)
console.log(error)
else
console.log('File saved');
})
})And the code to extract the thumbnail :
const ffmpeg = require('fluent-ffmpeg');
new ffmpeg(fileName).screenshots({
timestamps: [0],
filename: 'thumb.png',
folder: '.'
})And I am getting this error from
ffmpeg
Error: ffmpeg exited with code 1: ./test.mp4: Invalid data found when processing input
I know there is a problem in saving the file like this but I couldn’t find any solution that solves my problem. If anybody has one that would be much appreciated.
UPDATE :
It turns out thatffmpeg
does this for me, I just gave it theurl
and it downloaded what it needs to render the screenshot without the need to download the file locally and the code looks like this :const ffmpeg = require('fluent-ffmpeg');
new ffmpeg(url).screenshots({
timestamps: [0],
filename: 'thumb.png',
folder: '.'

video editing application on iOS - use AVFoundation or FFMpeg ? [on hold]
9 novembre 2016, par WillieHi,we will develop a video editing app for ios, users can add text,title or marks on video, and they can also add music, effects or filter for the video. finally, the most important is we can merge the everything that users added in this video and export it. just like iMovie on iOS.
AVFoundation is qualified for the job ? and what’s the difference between AVFoundation and FFMPeg in iOS ?
