Stream PNG file to youtube with ffmpeg
3 avril 2022, par codingmaster398What I'm trying to do :
I have a PNG file that is constantly getting written to. I want to pipe it (while it changes) to YouTube's RTMP server.


What I've attempted :


runCommand(
 'ffmpeg',
 `-threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 512 \
-loop 1 -re -i place.png \
-stream_loop -1 \
-filter:v "crop=in_w/2:in_h/2:1920:1280" \

 () => {},
 () => console.log('finished')
)

setInterval(()=>{
 image.write('./place.png') // Jimp },5000)

FFMPEG : Cannot read properties of undefined (reading 'format')
1er avril 2023, par DonnybI am currently to convert a video file to produce a thumbnail through ffmpeg, react-dropzone, and express. However I keep getting a error of "Cannot read properties of undefined (reading 'format')" in my console. For some reason it can not read the "metadata.format.duration" in my program, I have checked if ffmpeg is properly installed by running the ffmpeg —version in my console, and I get all the details, along with ffprobe —version as well.


Here is my code :
upload.js


router.post("/thumbnail", (req, res) => {
 let thumbsFilePath ="";
 let fileDuration ="";

 // req.body.filepath
 ffmpeg.ffprobe(req.body.filepath, function(err, metadata){
 console.dir(metadata);
 console.log(metadata.format.duration);

 fileDuration = metadata.format.duration;
 })

 ffmpeg(req.body.filepath) //req.body.filepath
 .on('filenames', function (filenames) {
 console.log('Will generate ' + filenames.join(', '))
 console.log(filenames);
 thumbsFilePath = "./uploads/thumbnails/" + filenames[0];
 
 })
 .on('end', function () {
 console.log('Screenshots taken');
 return res.json({ success: true, thumbsFilePath: thumbsFilePath, fileDuration: fileDuration})
 })
 .screenshots({
 // Will take screens at 20%, 40%, 60% and 80% of the video
 count: 3,
 folder: './uploads/thumbnails',
 size:'320x240',
 // %b input basename ( filename w/o extension )
 filename:'thumbnail-%b.png'
 });
})


FrontEnd drop code :
AddVideo.js


const onDrop = (files) => {

 let formData = new FormData();
 const config = {
 header: { 'content-type': 'multipart/form-data' }
 }
 console.log(files)
 formData.append("file", files[0])

 axios.post('http://localhost:5000/api/upload/uploadfiles', formData, config)
 .then(response => {
 if (response.data.success) {

 let variable = {
 filePath: response.data.filePath,
 fileName: response.data.fileName
 }
 setFilePath(response.data.filePath)

 //gerenate thumbnail with this filepath ! 

 axios.post('http://localhost:5000/api/upload/thumbnail', variable)
 .then(response => {
 if (response.data.success) {
 setDuration(response.data.fileDuration)
 setThumbnail(response.data.thumbsFilePath)
 } else {
 alert('Failed to make the thumbnails');
 }
 })


 } else {
 alert('failed to save the video in server')
 }
 })

 }

 return (
 <div style="{{">
 <div style="{{">
 {/* */}
 </div>

 <formcontrol>
 <div style="{{">
 
 {({ getRootProps, getInputProps }) => (
 <div style="{{" solid="solid">
 <input />
 <icon type="plus" style="{{"></icon>

 </div>
 )}
 
 </div>
 </formcontrol>
 </div>
 )
}


The video I am trying to upload is a mp4 file. I am using fluent-ffmpeg as a dependency.
