Hi,

Thanks for your feedback and update response as below.

 -> I have reviewed pull parsing apply in other FFmpeg case(container-codec
combination). I found that full parsing is sometimes used in limited
container-codec combination like asfdec.c. And so I applied full parsing in
AVI-MPEG1 / AVI-MPEG2 case. Also I verified this patch with embedded
development environment and checked 50 files.
Test result is OK and so suggested this patch.

> Otherwise I'd rather suggest to add an option to force full parsing + try
to make the decoder detect this case and suggest that option.

 -> I agree that your suggestion is more reasonable but unfortunately I did
not found solution to detect this case.

Thanks a lot.
