• java.lang.UnsatisfiedLinkError : Couldn't load ffmpeg library findLibrary returned null

  22 février 2017, par Muthukumar Subramaniam

  I am new to live streaming from android to youtube in android. I mentioned my Project Structrue and build the gradle file in android. FFmpeg library could not load in runtime.

  Note : I am working in windows 10 and android studio 2.1.2

• Configure ffmpeg with android in mac [on hold]

  28 novembre 2013, par Mr.G

  I'm using Mac 10.8.5

  i want to configure ffmpeg in my android application and convert .mov to .mp4 format.

  But first of all i want to configure ffmpeg in to my android project .

  Is there any way to do that . i have already tried some links . But when I'm loaded the libavcodec to my activity . it gives unsatisfied link error.

  Can anyone point me to a working link ?. It should compatible with Mac

  i have already tried How to build + include FFMPEG into an existing Android project "@William Seemann" answer. to configure it

  im pretty sure managed to add in to my android project . but when im tryng to load libavcodec it gives me An UnsatisfiedLinkException

• ffmpeg - Making a Clean WAV file

  10 janvier 2021, par Edward

  I'm looking to batch convert a number of files to audio files using ffmpeg for a game called Star Wars: Jedi Knight: Dark Forces II. The problem I'm having is that ffmpeg seems to be doing something that does so that Jedi Knight can't play the sound file.

  



  Jedi Knight accepts plain old PCM WAV files of various ranges, from 5khz to 96khz, 8 and 16 bit, mono and stereo. This sounds plain and simple. Except for that if one were to create a WAV file using MS Sound Recorder, Jedi Knight could not play it. Speculation was that it added something extra to header or something. But it can play a WAV file created by Audacity, GoldWave or ModPlug Tracker to name a few.

  



  So why not ffmpeg ? Am I using the wrong codec or params ? I took an original sound file from the game and performed the following :

  



  ffmpeg -i "orig_thrmlpu2.wav" -f wav -acodec pcm_s16le -ar 22050 -ac 1 "ffmpeg_thrmlpu2.wav"


  



  The ffmpeg version does not play in the game. ffprobe shows that the ffmpeg version has some Metadata which the original doesn't have. What params should I use to try and get the same WAV format as the original ? Mind you, -ar, -ac and bits aren't the important parts.

  



  Here are the files for you to examine : http://www.edwardleuf.org/Games/JK/thrmlpu2.zip
