[FFmpeg-cvslog] ffmpeg: reduce overloading for InputStream.pts.

[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sun Feb  5 20:56:24 2012 +0100| [d97fa416d62fe00a69e5be947d7c51b71982dd12] | committer: Michael Niedermayer

ffmpeg: reduce overloading for InputStream.pts.

It currently has different meanings at different times (dts of the last
read packet/pts of the last decoded frame). Reduce obfuscation by
storing pts of the decoded frame in the frame itself.
