[MPlayer-dev-eng] [PATCH] Seek in real media files

[陆然]

Hi,

There are two patches in the attachment, the first one improved seek function 
when playing real media files. the key point is: when using the idx for seek, 
either the files own index or the generated one, the audio frame must be a 
keyframe. Otherwise the seek will be failed. And I find the 'current_apacket' 
and 'current_vpacket' does not increace while the file is playing, so I add 
some code to keep it sync with the movie. The third improvment is that the 
original code doesn't work with the file's own index, the patch will add the 
support. 

  With this patch, MPlayer can seek in real media files using -forceidx or 
-idx, I recommend using -idx because I found -forceidx sometimes failed to 
generate the index from some movies. The code works at least for me, but is 
dirty and really need some cleanup. But I have no time since I have to head 
up to the DOCS translation. So feel free to modify it and please don't flame 
on me.:-)

  The other one is a ugly work around for the bug I reported several days ago. 
No one seems interested so I made a work around myself, I don't think it can 
be commited into the source, just hope it can be useful to test the first 
patch.
