• Suggestion query : Someone should add 'percent-complete' to ffmpeg's status line

  19 février 2018, par Dave

  I use the PC-platform’s ffmpeg (on Windows and Linux). I’ve always
  wondered why, down on that bottom dynamic status line, it does NOT
  show a ’percent-complete’ value.

  e.g. There’s already a line showing what time-line value is being worked
  on, so I’d expect it would be straight-forward to grab total duration, compute percent-complete, and show it, right after the running time value. Or,
  if based on frames, then show it in parentheses after the frame value.

  The reason I think it would be straight-forward is because I see it
  discussed in detail, for ffmpeg on Android, here :
  How to add progress bar to FFMPEG android
  and it talks about time-values and frame-count based calculations.

  Any volunteers to tackle this ? ^ ;)

• using default poster image with video and audio tags

  23 décembre 2016, par Ravinder Payal

  I have a web-application where users can share music and videos ( will be saved on sme-server utilized by Web-Application ) and as we know some audio /video files have posters/thumbnails included/attached with them.
  NOW, I want to show those posters with audio or video in HTML5.
  I know about poster tag, but it needs a separate image file to show. However, I want to show image file attached with song (audio / video).
  Any suggestion related any java-script or HTML api will be appreciated.
  I know about obtaining poster images with ff-mpeg(or similar libraries), but that will add an extra work load on my server. Thanks.

  Note :-I may consider any server side efficient solution alo.

  Thanks in advance.

• Split video with MobileFFmpeg

  17 septembre 2020, par Vitor Ferreira

  I need to split a video into pieces smaller than 15 seconds using ffmpeg on android.

  


  For this I am using this library to use FFmpeg and tried to use the code below, but it did not work.

  


      private val destPath = "/storage/emulated/0/DCIM/TESTFOLDER"


  


      if (video != null) {
        val command =
            "ffmpeg -i $video -c copy -map 0 -segment_time 00:00:15 -f segment $destPath output%03d.mp4"

        mProgressDialog.show()

        try {
            val executionId = FFmpeg.executeAsync(command) { _: Long, returnCode: Int ->
                when (returnCode) {
                    RETURN_CODE_SUCCESS -> {
                        mProgressDialog.dismiss()
                        Toast.makeText(
                            this,
                            "Async command execution completed successfully",
                            Toast.LENGTH_SHORT
                        ).show()
                    }
                    RETURN_CODE_CANCEL -> {
                        mProgressDialog.dismiss()
                        Toast.makeText(
                            this,
                            "Async command execution cancelled by user.",
                            Toast.LENGTH_SHORT
                        ).show()
                    }
                    else -> {
                        mProgressDialog.dismiss()
                        Toast.makeText(
                            this,
                            "Async command execution failed",
                            Toast.LENGTH_SHORT
                        )
                            .show()
                    }
                }
            }
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(this, e.message, Toast.LENGTH_SHORT).show()
        }
    }


  


  I tried with video = /data/user/0/com.vitor238.videoEditor/cache/e4c9d2f3-6127-43fa-a293-e0de614f4993.mp4 and video = content://media/external/video/media/187130 but neither worked.
