Use git blame: tree a3eb24614d470ec588bce56268f96c327b0d5c70 parent d07de6d75d36e9e953be7f0cdf82148c31a09b8a author Michael Niedermayer <[email protected]> Wed Mar 7 22:13:39 2012 +0100 committer Michael Niedermayer <[email protected]> Fri Mar 9 19:36:12 2012 +0100 lavf: Add system to seperate relative timestamps from absolute ones. With this we can always know if a timestamp is based on added durations from an unknown origin or if it is based on a correct timestamp (and possibly added durations) This should fix some bugs where this distinction was mixed up. Signed-off-by: Michael Niedermayer <[email protected]> Basically, RELATIVE_TS_BASE is the zero point for relative timestamp. Relative timestamp is in range of (RELATIVE_TS_BASE - 2^48, RELATIVE_TS_BASE + 2^48). > _______________________________________________ > ffmpeg-user mailing list > [email protected] > https://ffmpeg.org/mailman/listinfo/ffmpeg-user > > To unsubscribe, visit link above, or email > [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
