  convert request to begin encoding the video, and status request that retrieves
  * the current encoding status so the progress bar can be updated.

• Where can I download images/videos for all kind of pixel formats ?

  15 janvier, par Bukibarak

  I am developing a software that use FFMPEG AVPixelFormat for images and videos. I want it to be compatible with most common pixel formats.

  


  Is there a website where I can download images/videos that have all kind of pixel formats for testing purpose (like RGBA, BGRA, YUV, Greyscale, ...) ?

  


• Java merge ? mix ? 2 audio files(mp3) parallely and download it

  4 février 2024, par JoonSeo Yang

  is there any way to mix 2 audio files parallely and let user download it ?

  


  I was trying it by ffmpeg

  


  FFmpegBuilder builder = new FFmpegBuilder()
                .overrideOutputFiles(true)
                .setInput(audioInputPath1)
                .addInput(audioInputPath2)
                .addOutput(outputFilePath)
                .setFormat("mp3")
                .setAudioCodec("libmp3lame")
                .setAudioBitRate(256000)
                .done();

        executor.createJob(builder).run();


  


  but it doesnt work by codec problem, so i want to know if there any other way to reach my goal, or fix my ffmpeg code to make it work ?
