[Hendrik Leppkes]

ffmpeg | branch: master | Hendrik Leppkes <h.leppkes at gmail.com> | Thu Jun 30 14:10:42 2016 +0200| [c2e13d2ecd388bab28e743c34ed146c5ed213fc9] | committer: Michael Niedermayer

avformat/utils: update deprecated AVStream->codec when the context is updated

This ensures the AVStream->codec entry is kept in sync when new streams are
discovered mid-playback or changes to the context occur from other sources.

Fixes trac 5678.
