Video out of LinkedList sequence
14 janvier 2020, par Marks GniteckisI just started working on a side project to learn JavaFX 13 and the idea is to play a sequence of frames like a video without saving the actual video or frames in temp folders. I’d like to buffer images and output them onto ImageView at 30fps. Here is what I’ve got so far :
The method that buffers images -
@FXML void takeVideo(ActionEvent event)
throws InterruptedException {
model.purgeBufferedVideo();
Timer timer = new Timer();
long startedAt = System.currentTimeMillis();
TimerTask task = new TimerTask() {
@Override public void run() {
while (System.currentTimeMillis() < startedAt + (1000 * Long.parseLong(s.getText()))) {
generateVideo(new Rectangle(Toolkit.getDefaultToolkit()
.getScreenSize()));
System.out.println(System.currentTimeMillis() != startedAt + (1000 * Long
.parseLong(s.getText())));
}
cancel();
System.out.println("Video buffered");
}
};
timer.schedule(task, 0L);
}Method to output images onto ImageView -
@FXML void playVideo(ActionEvent event) {
model.getBufferedVideo().forEach(i -> {
try {
preview.setImage(i);
Thread.sleep((60000 / Long.parseLong(s.getText()))/30);
preview.setImage(i);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
}List population is working but only last image in the list is displayed in the ImageView and I can’t really get my head around why... Thanks in advance to everyone !

node.js - Error : ENOENT : no such file or directory, unlink
10 août 2020, par necrofaceI have the function below to convert a
.wavfile to.mp3. As you can see, before using theffmpegmodule to convert the audio file, I already check if the file exists or not, then upon conversion, I only keep the new file and delete the old one. But occasionally the console throws me the errorError: ENOENT: no such file or directory, unlink, which means that Iunlink(delete) a non-existing file. I cannot understand why, because I already have an existence check even before the conversion, so it is supposed to have existed to be unlinked.


module.exports.convertAndMoveElastic = async (calllog) => {
 let { start, sip_uri, direction, source, destination } = calllog;
 const VNtimezoneOffset = 7 + new Date().getTimezoneOffset() / 60;
 const startTime = new Date(start + VNtimezoneOffset * 3600000 - 60000);
 const date = startTime.getDate() < 10 ? `0${startTime.getDate().toString()}` : startTime.getDate().toString();
 const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
 const month = months[startTime.getMonth()];
 const year = startTime.getFullYear().toString();
 sip_uri = sip_uri || (direction === 'outgoing' ? source : destination);
 const [extension, domain_name] = sip_uri.split("@");
 return new Promise(async (resolve, reject) => {
 const links = await getLinkWithElastic(calllog);
 if (!links) { return reject(); }
 let file_id, filepath;
 for (let link of links) {
 const { callid, sipCallid, uuid, record_path } = link._source;
 if (record_path) {
 let recordPathArr = record_path.split('/');
 file_id = recordPathArr[recordPathArr.length - 1].split('.')[0];
 filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
 }
 if (!file_id || !fs.existsSync(filepath)) {
 file_id = callid;
 filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
 }
 if (!file_id || !fs.existsSync(filepath)) {
 file_id = uuid;
 filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
 }
 if (fs.existsSync(filepath)) { break; }
 }
 if (!fs.existsSync(filepath)) { return reject(); }
 ffmpeg(filepath)
 .audioCodec('libmp3lame')
 .on('error', function (error) {
 reject(error);
 })
 .on('end', function () {
 resolve({ recordUrl: `${host}/record/download/${file_id}.mp3` });
 fs.unlinkSync(filepath);
 })
 .toFormat('mp3')
 .saveToFile(path.resolve(dest_directory, file_id + ".mp3"));
 });

Convert chapters from xml to ffmetadata ?
3 février 2021, par Soul SparkI wanted to add chapters to my encoded mkvs, but I get
*.xmlfiles when I download it from online. So is there any way to convert it toFFMETADATAFILEso that when I encode it using ffmpeg I can add chapters to my mkv ??
