• Need help to remove repetitions or duplicated frams in my podcast videos

  19 décembre 2020, par Måns Bredelius

  I record videos in a strange way. When I record my podcast videos I often record in the same conversation twice within the same video.

  


  If you would look at it you would see and hear something like this.

  


  "I open the door I open the door and let him in".

  


  I open the door was recorded twice in this example. Currently, I am manually removing these things myself in DaVinci resolve afterward. But I have heard that FFMPEG and mpdecimate are things that could do some wonders here.

  


  I found a video on youtube and found this code
ffmpeg -i original_file.mp4 -vf mpdecimate -vsync vfr -acodec copy mpdecimated.mp4

  


  but nothing happened. Something did happen, it did do something, but nothing happened to my video.

  


  Would love some help.

  


• Merge Videos using fluent-ffmpeg

  25 octobre 2023, par Andronik Nazaryan

  I'm trying to merge two videos, the following code works perfectly on windows 10, but it gives me an error when trying to run it on linux/ubuntu, same on wsl

  


      async joinVideo(): Promise<boolean> {&#xA;        return new Promise((resolve, reject) => {&#xA;            signale.info(&#x27;Joining video&#x27;)&#xA;            const profile = path.join(__dirname, &#x27;../videos/input/profile.mp4&#x27;)&#xA;            const sb = path.join(__dirname, &#x27;../videos/input/sb.mp4&#x27;)&#xA;&#xA;            const joined = path.join(__dirname, &#x27;../videos/profile-sb.mp4&#x27;)&#xA;            const tempFolder = path.join(__dirname, &#x27;../videos/temp&#x27;)&#xA;&#xA;            ffmpeg({ source: profile })&#xA;                .input(sb)&#xA;                .on(&#x27;end&#x27;, () => {&#xA;                    signale.success(&#x27;Video joined&#x27;)&#xA;                    resolve(true)&#xA;                })&#xA;                .on(&#x27;error&#x27;, err => {&#xA;                    signale.error(err)&#xA;                    reject(false)&#xA;                })&#xA;                .mergeToFile(joined, tempFolder)&#xA;        })&#xA;    }&#xA;</boolean>

  


  The error i get

  


  Error: ffmpeg exited with code 1: Error reinitializing filters! &#xA;Failed to inject frame into filter network: Invalid argument&#xA;Error while processing the decoded data for stream #1:0&#xA;Conversion failed!&#xA;&#xA;    at ChildProcess.<anonymous> (/mnt/c/Users/Anri/Desktop/lead-gif-generator/node_modules/.pnpm/fluent-ffmpeg@2.1.2/node_modules/fluent-ffmpeg/lib/processor.js:182:22)&#xA;    at ChildProcess.emit (node:events:517:28)&#xA;    at ChildProcess.emit (node:domain:489:12)&#xA;    at Process.ChildProcess._handle.onexit (node:internal/child_process:292:12)&#xA;</anonymous>

  


  the installation of fluent-ffmpeg should be correct as other operations are working, only mergeToFile function is erroring out

  


  also strange thing is that if i put same file in both inputs it works fine, my guess it happens because of differance between videos, but why it works on windows

  


• Playing Several Videos in a Row From a Browser

  2 août 2014, par user18490

  It’s simple to play 1 video (using HTML5), but my question is, can you play 2 or more videos in a row.

  Basically I’d like to let the user select as many clips as he/she wants, and let him/her play them in the browser (or potentially an external player such as FFplay, but the browser is my goal for now). It’s similar to the concept of playlist in Youtube, ... there should be no cut between two consecutive clips (which is the case right now with playlist in Youtube).

  Is that possible with existing API/tools/techniques ?
