This is a great question. I'm just now trying to familiarize myself
with the 3.1 API, and little things like this come up. I'd like to
know the answer to this as well.
Perette, have you tried the IRC channel?

same but different?
AVCodec * codec = avcodec_find_decoder( av_fmt_ctx->streams[ stream_id
]->codecpar->codec_id );
if ( !codec )
[...]
av_codec_ctx = avcodec_alloc_context3( codec );
if ( !av_codec_ctx )
[...]
if ( avcodec_parameters_to_context( av_codec_ctx, av_fmt_ctx->streams[ stream_id
]->codecpar ) < 0 )
Thanks
