webrtc/api/video_codecs/video_decoder.h
Niels Möller 802506c2e9 Add placeholder header file api/video_codecs/video_codec.h.
This is a preparation for moving declaration of the VideoCodec class
to this file. Applications using the legacy VideoCodec class should
start including this file instead of common_types.h.
