  The following is the output for issuing init-submodules.sh. I keep receiving this

  error:fatal error:

  Has anyone run jhotovy's version of halfninja's code successfully so far ? Any help in resolving this issue will be greatly appreciated

  I have successfully run the original halfninja version which is also at githuib.com/halfninja/android-ffmpeg-x264.<br> I have searched all over the Internet and i am not finding any reference to this issue. Anyone had any success with that implementation

• Encoding for HLS using FFMPEG results in have a decreasing DTS

  29 décembre 2014, par Luuk D. Jansen

  I am trying to encode video for HTS live streaming, but am having problems with validating the stream using Apple Media Validator (mediastreamvalidator).
  (my test file : http://dominicansinteractive.idoms.org/media/9536/playlist.m3u8)

  The output is :

  --------------------------------------------------------------------------------

  --------------------------------------------------------------------------------

      OK

  The second segment doesn’t seem to have the problem :

  This seems to be a serious problem for HLS, so I am looking if there is a way to fix this.

  When looking with FFMPEG at the encoded file I get (encoder output/command at the bottom of the email) :

  ffmpeg, -i,[path]encoded.ts, -y, -c, copy, -flags, global_header, -map, 0, -f, segment, -segment_time, 10, -segment_list, [path]/fileList.txt, -segment_format, mpegts, [path]/segment_%05d.ts]

  Any help would really be appreciated !
