Synopsis:Some avi video files can not be playback

Overview:When playing some avi video files,it may fail due to some reasons.
1.> 1.100_H264_mp3_176x144_148Kbps_30fps_BP.avi
It was caused by failing to initialize decoder with opaque data.When initializing
the decoder,opaque data is always important,but not essential,because maybe the
decoder has the capability of initializing itself with following input data.Finally,
update the logic to conceal the error when parsing opaque data.It will give decoder
a chance to initializing itself.It is reasonable and adoptable.

2.>1.112_toystory_h264_aac+.avi
It was caused by initializing the aac audio render failure with the opaque data.For
avi files,if the chunk named "strd" miss,we will try to read the first frame as \
opaque data.This behavior is reasonable,however,failure may occur due the the first \
frame is not appropriate to regard as opaque data.
In order to conquer this issue,firstly,adding the functionality for validate the \
opaque data. If it is invalid,try to initialize the decoder with default audio \
specific config.Secondly, try to separate the aac mime type by checking the adts sync \
word.

3.> Update the method for extracting the resolution of H.264 and MPEG4.
The is some shortcomings of the resolution extraction of H.264 if the profile is high \
profile. Meanwhile,for MPEG4 files,adding the functionality to extract the \
resolution.
