• ffmpeg hevc decoding fail [android]

  8 mars 2016, par revannen

  I am trying to decode h.265 with x265 and ffmpeg library, so that I downloaded ffmpeg 2.8.6 tar and x265 1.9 ver from the official site.

  now, the problem is when I decode h.264 with
  avcodec_find_decoder(AV_CODEC_ID_H264) ;
  is totally fine. :)

  but, when I try to decode h.265 with
  avcodec_find_decoder(AV_CODEC_ID_H265) ;
  it tells lots of error log.
  like.

  E/native(4153) : FAIL......-12

  1. Is it ffmpeg error ? or x265 library error ?

  2. should I modify some configuration key value in build level ? or ffmpeg running time level ?

  3. I would like to know why ffmpeg library keep saying like "No start code is found" && "PPS id out of range" [it is occur in only 265 decoding case, not 264.]

• How to prepare media stream to play using dash.js web player ?

  7 avril 2016, par Paweł Tobiszewski

  I want to stream media from nginx server to Android device and play it using web player embedded into web page. Player I want to use is dash.js.
  I play the same media also using different methods (MediaPlayer and ExoPlayer) and they are working great. But when I try to use dash.js, I faced problem with codecs - they are not supported.
  I prepare my streams using ffmpeg and MP4Box, I also tried different codecs, like libx264, x264, x265 - always with the same effect.
  My based media are video in Y4M format and audio in WAV.
  How to encode it to use it in dash.js player ?

  EDIT :
  I get error "Video Element Error : MEDIA_ERR_DECODE" while trying to decode video stream.

  Here is full log :
