Summary0000418: Start time / pre-roll problems

There have been various problems with either content being trimmed from the start of movie files, or extra content being played that shouldn't be.

122e384b3c3d1bed9111b792640e3b0d0233c3a2 (in 1.69.14) took AVFormatContext start_time into account when calculating how long VideoContents are (i.e. duration - start_time = actual duration). This was in response to a bug report from sguha.

48c6b80a82ffb2865da5f592753ebde789694878 (in 1.72.12) reverted this.

sguha reports that in 1.73.0 "there is some color bars and cues (not seen in Quicktime) at the beginning, while the end is getting clipped considerably with no end credits.", which does not happen in 1.70. See the attached ffprobe.log; this ffprobe.log correctly describes the duration as 7:47 (sghua confirms that this is the duration the video should have when played back correctly).

mantis-418 now does not play anything before time 0. sguha reports that it works in his test case.

I'll mark this as fixed; merged into master just after 1.76.28.
