[Libav-user] avcodec_decode_video2 gets wrong frame dimensions

I'm using ffmpeg1.0 (with code name of "Angle") as H264 decoder, following
the sample code in doc/examples/decoding_encoding.c. I use it to decode a
compressed H264 bit stream. The resolution is 1280x800. However, after
calling avcodec_decode_video2, coded_width = 800 and codec_height = 1280,
while width = 0 and height = 1280. It seems that the values of width and
height are exchanged.
Is it a bug?
