[MOVED FROM BAD 081/134] vp8enc: generate a timestamp for alt-ref frames.
It will fix handling of altref/invisible frames since matroska-mux drop any fram with no timestamp. see also: http://www.webmproject.org/code/specs/container/ The encoder will currently set the AR's timestamp as close as possible to the previous frame while attempting to provide a timestamp that is strictly increasing. In cases where the time base given to the encoder at configure time is not granular enough to allow for this the AR will share the same timestamp as D, but should be treated as having no duration. Fixes bug #652951 Signed-off-by: Alexey Fisher <bug-track@fisher-privat.net>
