[Libav-user] Possible memory leak with avcodec_decode_video2

[David Tsulaia]

Hello everyone,

I know there are millions of threads/mails about this, but none have
similar cases.

OS - Ubuntu 14.04.2 LTS and all libav devel pkges are
 6:9.18-0ubuntu0.14.04.1+fdkaac version.

ffmpeg version N-75912-g624057d Copyright (c) 2000-2015 the FFmpeg

  libswresample   2.  0.100 /  2.  0.100
  libpostproc    54.  0.100 / 54.  0.100

Sample code:

I tried both av_frame_unref and av_frame_free after decoding frame and in
case of free I call av_frame_alloc() again;

No matter what I try call to avcodec_decode_video2 results in memory leak.
One distinguishing factor from normal cases is that the input stream is
quite large.

Any help or ideas are appreciated,
Thanks in advance.
