[Libav-user] AVStream->codec deprecation

[salsaman]

Here we go, I can answer definitively now:

https://ffmpeg.org/doxygen/3.1/ffplay_8c_source.html


AVCodecContext <https://ffmpeg.org/doxygen/3.1/structAVCodecContext.html>
*avctx;

avctx = avcodec_alloc_context3
<https://ffmpeg.org/doxygen/3.1/group__lavc__core.html#gae80afec6f26df6607eaacf39b561c315>
(NULL
<https://ffmpeg.org/doxygen/3.1/coverity_8c.html#a070d2ce7b6bb7e5c05602aa8c308d0c4>
);
if (!avctx)
   return AVERROR
<https://ffmpeg.org/doxygen/3.1/group__lavu__error.html#gae4bb6f165973d09584e0ec0f335f69ca>
(ENOMEM);

ret = avcodec_parameters_to_context
<https://ffmpeg.org/doxygen/3.1/group__lavc__core.html#gac7b282f51540ca7a99416a3ba6ee0d16>(avctx,
ic->streams
<https://ffmpeg.org/doxygen/3.1/structAVFormatContext.html#acfefb6b6cf21e87a0dcbd1a547ba2348>
[stream_index]->codecpar
<https://ffmpeg.org/doxygen/3.1/structAVStream.html#a12826d21779289356722971d362c583c>
);
if (ret < 0)
  goto fail
<https://ffmpeg.org/doxygen/3.1/checkasm_8h.html#a73a3b169ac8c3419cbe15327e75ffcfd>
;
