Buffer as input and output for fluent-ffmpeg
9 septembre 2022, par nickcoding2The below looks like a lot but a it's primarily just output.


I'm trying to take in a buffer using multer (being send the request containing the video (.mov format) through Alamofire from an iPhone) as the input before a fluent-ffmpeg conversion, then I want it to output as a buffer, and then send the result to S3. I think I'm close, but I don't think fluent-ffmpeg can have a buffer passed in. This is deployed on heroku using this buildpack : https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.... How do I pass it in correctly ?


const multer = require('multer')
const upload = multer({ limits: { fieldSize: 100_000_000 } })
app.post('/create', upload.single('video'), async function (request, response, next) {
 let data = request.body
 console.log(data) // prints [Object: null prototype] { param1: '' }
 let bufferStream = new stream.PassThrough();
 console.log(request.file.buffer) // prints '<buffer 00="00" 14="14" 66="66" 74="74" 79="79" 70="70" 71="71" 20="20" 08="08" 77="77" 69="69" 64="64" 65="65" 01="01" 0e="0e" 28="28" 55="55" 6d="6d" 61="61" 21="21" 03="03" 40="40" 68="68" 1c="1c" 4e="4e" ff="ff" 3c="3c" 59="59" 96="96" 7c="7c" 82="82" 17718642="17718642" more="more" bytes="bytes">'

 new ffmpeg({
 source: stream.Readable.from(request.file.buffer, { objectMode: false })
 })
 // .format('mp4')
 .on('error', function (err) {
 console.log(Error: ${err})
 })
 .on('progress', function (progress) {
 console.log("progress")
 })
 .on('end', function () {
 console.log('Formatting finished!');
 console.log("after");
 })
 .writeToStream(bufferStream);

 // Read the passthrough stream
 const buffers = [];
 bufferStream.on('data', function (buf) {
 buffers.push(buf);
 });
 bufferStream.on('end', function () {
 const outputBuffer = Buffer.concat(buffers);
 // use outputBuffer
 });
 console.log("Added.")
 response.send("Success")
});
</buffer>

The output is what you can see below (without .format('mp4')) :

My uploadFile function works correctly because I use it elsewhere—normally, I just pass in the request.file.buffer, but here it needs to be a buffer after the ffmpeg conversion


EDIT :


At Heiko's suggestion, I tried changing the multer initialization to


multer({ limits: { fieldSize: 100_000_000 }, dest: "uploads/" })


and the source I was passing in to ffmpeg to


new ffmpeg({
 source: request.file.path // request.file.path seems to be a path of a Multer-generated file, I'd assume the one I'm sending to the server
})
.format('mp4')


but it still errored out to


Error: ffmpeg exited with code 1: Conversion failed!


when the request.file was :


{
 fieldname: 'video',
 originalname: 'video',
 encoding: '7bit',
 mimetype: 'clientMime',
 destination: 'uploads/',
 filename: '08d5d3bbdcf1ac29fb97800136a306e9',
