• Android ffmpeg Issue :- : No such file or directory

  15 février 2014, par Nirav Dangi

  I am using FFMPEG tool to merge IMAGE & AUDIO files. Its working only in SAMSUNG GALAXY TAB II.
  I had tried in many android devices & emulators but unfortunately it had not worked in any of them.

  Same issue is posted here also. But Its solutions has not worked for me.

  Following is error log of emulator,

• ffmpeg decoding on Android

  29 novembre 2013, par Kernald

  I'm currently trying to use ffmpeg on Android. I built ffmpeg using https://github.com/halfninja/android-ffmpeg-x264 (I adapted it to not use libx264 and build with ndk-r9b, using GCC 4.6). I try to trim an MP4 file. However, the input file fails to open :

  I digged into ffmpeg's code, and found the error :

  static int opt_input_file(OptionsContext *o, const char *opt, const char *filename)
  
  {
  
  
  
  // ...
  
  
  
  ic->video_codec_id   = video_codec_name ?
  
      find_codec_or_die(video_codec_name   , AVMEDIA_TYPE_VIDEO   , 0)->id : CODEC_ID_NONE;
  
  ic->audio_codec_id   = audio_codec_name ?
  
      find_codec_or_die(audio_codec_name   , AVMEDIA_TYPE_AUDIO   , 0)->id : CODEC_ID_NONE;
  
  ic->subtitle_codec_id= subtitle_codec_name ?
  
      find_codec_or_die(subtitle_codec_name, AVMEDIA_TYPE_SUBTITLE, 0)->id : CODEC_ID_NONE;
  
  ic->flags |= AVFMT_FLAG_NONBLOCK;
  
  ic->interrupt_callback = int_cb;
  
  
  
  if (loop_input) {
  
      LOGW(
  
          "-loop_input is deprecated, use -loop 1\n"
  
          "Note, both loop options only work with -f image2\n"
  
      );
  
      ic->loop_input = loop_input;
  
  }
  
  
  
  /* open the input file with generic avformat function */
  
  err = avformat_open_input(&ic, filename, file_iformat, &format_opts);
  
  if (err < 0) {
  
      print_error(filename, err);
  
      exit_program(1);
  
  }
  
  assert_avoptions(format_opts);
  
  
  
  // ...
  
  
  
  }

  As indicated in the logcat, err is here equal to AVERROR_INVALIDDATA. I don't understand the reason however : the mp4 codec is enabled, as far as I can tell. Any hint on how to solve it ?

  Edit : I added more ffmpeg code. I'm pretty sure it's a codec issue now : ic->video_codec_id is set to CODEC_ID_NONE, which causes ic to be set to NULL and return a failure in avformat_open_input().

• Using FFMPEG with Powershell

  19 mai 2017, par Caulen

  I am using Windows Server Edition 2012 and am very new to using Powershell. Basically, I am trying to convert a bunch of video files that are in a directory to .flv. The code I am using is this :

  $inProcessPath = "E:\Random Videos\In Process\$env:username\"
  
  
  
  $oldVideos = Get-ChildItem -Include @("*.mp4", "*.avi", "*.divx", "*.mov", "*.mpg", "*.wmv", "*.mkv") -Path $inProcessPath -Recurse #gets all of the videos
  
  
  
  cd "E:\FFMPEG\bin\"
  
  
  
  foreach ($oldVideo in $oldVideos) {
  
      $newVideo = [io.path]::ChangeExtension($oldSong.FullName, '.flv')
  
      .\ffmpeg.exe -i $oldVideo -y -async 1 -b 2000k -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast $newVideo 
  
  }

  Whenever I run this I don’t get any error messages but ffmpeg doesn’t run either. I’m sure I’m overlooking something but have no idea what that could be. I’ve searched the website and compared code to others and still have no idea.

  Any help would be very much appreciated.
