[FFmpeg-cvslog] avconv: move the avcodec_find_decoder() call to add_input_streams().

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Mon Aug 22 12:48:06 2011 +0200| [c74b44de08ffc2853f872c8a5d31526cdbacfc89] | committer: Anton Khirnov

avconv: move the avcodec_find_decoder() call to add_input_streams().

This makes the code simpler to understand, though it results in an
unnecessary call to avcodec_find_decoder() if the stream won't be
decoded.
