Exactly:
*For muxing/encoding:avcodec_parameters_from_context(stream->codecpar, codec_ctx); * That's what I am talking about.In my case ,codec_ctx is context I access from the input stream. I don't create it. So the deprecation warning is appears in this case. I don't see why I have to create codec context just to get rid of those warnings.
