09-26 16:02:24.740: I/VideoDecoder(135): maxDPBSize = 6, num_ref_frame = 5
09-26 16:02:24.740: I/VideoDecoder(135): updateFormatInfo: current size:
854 x 480, new size: 864 x 480
09-26 16:02:24.740: I/VideoDecoder(135): Video size is changed.
09-26 16:02:24.740: I/VideoDecoder(135): New sequence is received. Assuming
video size is changed.

= 10, bottom = 0

The VideoDecoder update the format info from size 854x480 to size 864x480
where the content size is actually 854x480.
I also tested other content that size 1920x1080 is changed to size
1920x1088.
Only the content with size 1280x720 remains the size and is played properly.
I'm pretty sure setting the correct size while creating video format.
I wonder, in what situation and how, the video decoder will update the
format info.
