• Converting FFMpeg Video to android playable video

  15 avril 2021, par Soham Samanta

  I had some image sequence and I used them to make a video using FFMpeg. It palyed well on VLC (windows and android) but not on built in android video player.
Codec and container info of the video is the following -

  


  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '../clg/clg_eq_final_injected.mp4':
  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41
    encoder         : Lavf57.83.100
  Duration: 00:00:12.13, start: 0.000000, bitrate: 9058 kb/s
    Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 4096x2048, 9057 kb/s, 24 fps, 24 tbr, 12288 tbn, 24576 tbc (default)
    Metadata:
      handler_name    : VideoHandler
    Side data:
      spherical: equirectangular (0.000000/0.000000/0.000000)


  


  I made a workaround by uploading the video on youtube. Then I downloaded it again. It's codec info is following -

  I noticed that the first video does not have any audio stream (since it's just an image sequence). But youtube arbitrarily added an audio stream. (I tried on android after adding an audio stream with it but no luck)
What I know -

  


  

  1. Android does not natively support motion JPEG.

  


  2. H264 is supported by android.

  


  


  Q1. What is the difference between h264(constrained baseline) vs h264(main) ?
Q2. Why the first video is not natively supported on android ?
My uploaded youtube video is here.

• Android ffmpeg Command not executing

  22 juin 2020, par MoTahir

  I am using this FFMPEG library,

  


  first I am playing the video inside my videoView to make sure that the video path is correct

  


  videoView.setVideoURI(Uri.parse(getExternalFilesDir(null)?.absolutePath + "videoToBeEdit"))


  


  then I am calling the code written below to crop the video then put it inside the videoView again just to see the result

  


  val ff = FFmpeg.getInstance(this@EditVideoActivity)
if (ff.isSupported){

  val inFile = File(getExternalFilesDir(null)?.absolutePath ,"videoToBeEdit")
  val outFile = File(getExternalFilesDir(null)?.absolutePath , "result")

  val command = arrayOf("ffmpeg","-i", inFile.absolutePath , "-filter:v", "crop=100:100:0:0", outFile.absolutePath)

  ff.execute(command, object : ExecuteBinaryResponseHandler() {
    override fun onSuccess(message: String?) {
      super.onSuccess(message)
      videoView.setVideoURI(Uri.parse(getExternalFilesDir(null)?.absolutePath + "videoToBeEdit"))
    }

    override fun onProgress(message: String?) {
      super.onProgress(message)
    }

    override fun onFailure(message: String?) {
      super.onFailure(message)
      Log.e("error", "failed")
    }

    override fun onStart() {
      super.onStart()
      Log.e("start", "started the process")
    }

    override fun onFinish() {
      super.onFinish()
      Log.e("finish", "done")
    }
  })
}


  


  but my code above goes from start to error then finish, it doesn't show any error messages and that's making it really hard to know what's actually wrong :( I tried to write my command in different ways following those tutorials tutorial1 tutorial2 link
please help, thank you in advance...

  


• ffmpeg Live Streaming Error : av_interleaved_write_frame() : Broken pipe

  5 octobre 2022, par Krishnakumar

  I am trying to stream video live using ffmpeg, Input is from a UDP Source. Most of the time it works fine, but I could see the following log lines and ffmpeg stop's the conversion/feed push to the rtmp server. Few log lines below for reference. Is this issue related to network on reaching the destination or source or something that i need to change in the ffmpeg command ?
