Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

Problem when adding background music to video without sound
27 avril 2020, par Nguyễn TrọngI am trying to cut a piece of background music and loop them into a video and change the speed of the video with the command below.



String[] cmd = {"-y", "-i", input, "-i", shortsound,
 "-filter_complex",
 "[0:v]trim=0:120,setpts=1/2*(PTS-STARTPTS)[v1]," +
 "[0:v]trim=120:240,setpts=1/2*(PTS-STARTPTS)[v2];" +
 "[1:a]atrim=0:6,asetpts=PTS-STARTPTS," +
 "asetrate=44100,aloop=-1:2e+09," +
 "aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.0[bg];" +
 "[0:a]atrim=0:120,asetpts=PTS-STARTPTS,atempo=2.0" +
 ",aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo[a1]," +
 "[0:a]atrim=120:240,asetpts=PTS-STARTPTS,atempo=2.0," +
 "aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo[a2];" +
 "[v1][a1][v2][a2]concat=n=2:v=1:a=1[video][audio];[audio]volume=0.5[avolume];" +
 "[avolume][bg]amerge=2,pan=stereo|c0code>


Everything was fine until I tried with a video without sound, it didn't work.
How when input is a video without sound ?

Anyone knows what might be the problem with this video output ?
31 janvier 2020, par KrishnakumarI am seeing the following scrambled output for a live stream when processing an udp input stream. I am using the recently downloaded ffmpeg from GIT. Stop and Start of ffmpeg command resolves the issues temporarily.

Is there any memory problem that "Too many active WebGL contents." keeps coming out in my web console
18 novembre 2022, par jerry


Now I'm using RTSP stream with jsmpeg, ffmpeg, node-rtsp-stream in React.js


I set multiple streaming in react component about 1 to maximum 25


and when I change route to many , It apeard my console


I'm a little afraid of if it caused by memory leak problem


I cannot figure out it is okay or critical problem


Could you tell me how to solve this problem or is it fine



// out of component
const streams: Streams = {};

...

 const { preset } = props;

 const elementsRef = useRef<any>(new Array(preset?.partition).fill(0).map((v) => createRef()));


 // Mount
 useEffect(() => {
 const { JSMpeg } = window;

 const sortedStream = _.sortBy(preset?.stream, ["position"]);
 console.log(sortedStream);


 sortedStream.forEach((v, i: number) => {

 const player = new JSMpeg.Player(v.camera_monitoring.ws, {
 canvas: elementsRef?.current[v.position]?.current, // Canvas should be a canvas DOM element
 });
 console.dir(elementsRef?.current[v.position]?.current);

 streams[v.id] = player;
 });
 }, []);

 // UnMount
 useEffect(() => {
 return () => {
 Object.keys(streams).forEach((v) => {
 console.log("unmount key:", v);
 if (streams[v] !== null) {
 streams[v].destroy();
 streams[v] = null;
 }
 });
 };
 }, []);



... 
</any>

above library `jsmpeg.min.js` is set by global ( in public directory and set in my html )


actually my code are so many antipattern in contrast react style, To make an excuse, It is my limits of one's ability
