Matthieu Bouron 72eaf72623 lavf/utils: avoid decoding a frame to get the codec parameters ...

Avoid decoding a frame to get the codec parameters while the codec
supports FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM. This is particulary useful
to avoid decoding twice images (once in avformat_find_stream_info and
once when the actual decode is made).
