• FFMPEG encrypted HLS single file is unplayable

  17 septembre 2019, par 3bodyZZ

  i use this command to generate the byterange segments

  ffmpeg -i test.mp4 -hls_time 20 -hls_flags single_file -hls_key_info_file key_info out.m3u8
  here is the output m3u8

  #EXTM3U
  
  #EXT-X-VERSION:4
  
  #EXT-X-TARGETDURATION:24
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-KEY:METHOD=AES-128,URI="key.bin"
  
  #EXTINF:23.933333,
  
  #EXT-X-BYTERANGE:1016328@0
  
  out.ts
  
  #EXTINF:19.200000,
  
  #EXT-X-BYTERANGE:824192@1016328
  
  out.ts
  
  #EXTINF:16.866667,
  
  #EXT-X-BYTERANGE:714024@1840520
  
  out.ts
  
  #EXT-X-ENDLIST

  and it does output incorrect byte range m3u8 file that is unplayable, i have tried the multiple segments and it works just fine but i need the single file, any one knows how to fix this ?

  here is the logs from ffmpeg

  i have also tried different videos, and i have tried ffmpeg on windows and linux , i have tried compiling it myself and nothing seems to work the segments keeps repeating after reaching a certain point in the video

• FFMPEG concat audio and videos produces only audio

  19 septembre 2019, par justaguytrynabuildawebsite

  Im trying to combine multiple video files with a single audio file. When using only videos without audio, it works fine but when adding a audio track to the beginning of the concat file i get the return below, and the output.mp4 becomes just audio with no video when previewing in browser.
  FFMPEG command

  ffmpeg -f concat -safe 0 -i /var/www/html/video_tool/edit/out/concat.txt -c copy -flags +global_header /var/www/html/video_tool/edit/out/output.mp4

• avformat_open_input crash using ffmpeg on android

  2 octobre 2019, par Timmy K

  I am writing an Android app to capture audio streams from a USB device using ffmpeg, and mux them into an m4a file. I then open the recording file to read back the audio data. The app works fine on Samsung S8 (Android 8.0) and S9 (Android 9.0). On a Moto G5+ (Android 8.1), however the app crashes inside avformat_open_input() when I try to open the recording file ; but if I restart the app and it reads the same file with the same code, it works without crashing.

  I thought maybe that I hadn’t closed the recording file properly ; or there was maybe a race condition : trying to read the file before it was written. However I have established that av_write_trailer() is called successfully and avio_closep() is called successfully before the call to avformat_open_input. I also established that the length of the file is the same just before the call to avformat_open_input() in the crash case as it is in the non-crash case.

  The code that finishes the recording :

  // AVFormatContext *mAvFormatContext
  
  // ...
  
  int ret = av_write_trailer(mAvFormatContext);
  
  if ( ret != 0 )
  
  {
  
      __android_log_print(ANDROID_LOG_DEBUG, "MyTag", "failed to write trailer %s", av_err2str( ret ) );
  
      goto fail;
  
  }
  
  
  
  ret = avio_close( mAvFormatContext->pb );
  
  if ( ret < 0 )
  
  {
  
      __android_log_print(ANDROID_LOG_DEBUG, "MyTag", "failed to avio_close %s", av_err2str( ret ) );
  
      goto fail;
  
  }
  
  
  
  avformat_free_context(mAvFormatContext);

  The call that causes a crash immediately after the above code, on a Moto 5G+ (but not Samsung S8/S9) :

  mAvFormatContext = nullptr;
  
  if ( (ret = avformat_open_input( &mAvFormatContext, filePath, 0, 0)) < 0 )
  
  {
  
      __android_log_print(ANDROID_LOG_DEBUG, "MyTag++", "Could not open input file '%s' error %s ", filePath, av_err2str(ret) );
  
      cleanup();
  
      return false;
  
  }

  Also, when the call to avformat_open_input() does not crash, there is no output in logcat from within that call. However, I’ve noticed that in the crash case there is output of what seems to be corrupted data :

  (crash occurs)

  Any advice on what to look into further to investigate this problem ? Is there something I am missing when cleaning up the muxing state before I try to open the recording file for demuxing ? For simplicity I have not included the freeing of codec contexts, AVFrames and AVPackets.
