• Error while opening encoder for output stream #0:0 for Creating Video from image,Gif,music

  29 février 2020, par brijesh

  I am trying to create a video from image,gif and music.

  Here is the code I used :

  {"-y", "-i", imagepath, "-ignore_loop", "0", "-i", gif, "-filter_complex", "[1:v]scale=" + filterdBitmap.getWidth() + ":" + filterdBitmap.getHeight() + "[ovrl];[0:v][ovrl]overlay=0:0", "-ss", "" + startMs / 1000, "-t", "" + endMs / 1000, "-i", songpath, "-c:v", "libx264", "-preset", "ultrafast", "-r", "30", "-pix_fmt", "yuva420p", "-c:a", "aac", "-shortest", outputLocation.getPath()};

  The error I received was this :

  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  Specifically, here is the complete response :

  Any idea what is going on here ? Thanks !

• Decode mp3 using FFMpeg, Android NDK - What is wrong with my AVFormatContext ?

  27 février 2020, par michpohl

  I am trying to decode am MP3 file to a raw PCM stream using FFMpeg via JNI on Android. I have compiled the latest FFMpeg version (4.2) and added it to my app. This did not make any problems.
  The goal is to be able to use mp3 files from the device’s storage for playback with oboe

  Since I am relatively inexperienced with both C++ and FFMpeg, my approach is based upon this :
  oboe’s RhythmGame example

  I have based my FFMpegExtractorclass on the one found in the example here. With the help of StackOverflow the AAssetManageruse was removed and instead a MediaSource helper class now serves as a wrapper for my stream (see here)

  But unfortunately, creating the AVFormatContext doesn’t work right - and I can’t seem to understand why. Since I have very limited understanding of correct pointer usage and C++ memory management, I suspect it’s most likely I’m doing something wrong in that area. But honestly, I have no idea.

  This is my FFMpegExtractor.h :

  #define MYAPP_FFMPEGEXTRACTOR_H
  
  
  
  extern "C" {
  
  #include <libavformat></libavformat>avformat.h>
  
  #include <libswresample></libswresample>swresample.h>
  
  #include <libavutil></libavutil>opt.h>
  
  }
  
  
  
  #include <cstdint>
  
  #include <android></android>asset_manager.h>
  
  #include 
  
  #include <fstream>
  
  #include "MediaSource.cpp"
  
  
  
  
  
  class FFMpegExtractor {

      FFMpegExtractor();

  When the code is executed, I can see that I submit the correct file path, so I assume the resource mp3 is there.
  When this code is executed the app crashes in line 103 of FFMpegExtractor.cpp, at formatContext.reset(tmp);

  This is what Android Studio logs when the app crashes :

  --------- beginning of crash
  
  2020-02-27 14:31:26.341 9852-9945/com.user.myapp A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x7fffffff0 in tid 9945 (chaelpohl.loopy), pid 9852 (user.myapp)

  This is the (sadly very short) output I get with ndk-stack :

  ********** Crash dump: **********

  Crash dump is completed

  I tested a bit around, and every call to my formatContext crashes the app. So I assume there is something wrong with the input I provide to build it but I have no clue how to debug this.

  Any help is appreciated ! (Happy to provide additional resources if something crucial is missing).

  FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.

  Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get this error message :

  npm WARN deprecated ffmpeg-binaries@4.0.0: ffmpeg-binaries is no longer being maintained. use ffmpeg-static, or just install ffmpeg
