Description Tim-Philipp Müller 2010-01-25 12:35:04 UTC 
Looks like videomixer may not timestamp outgoing buffers properly when one of the input streams is short than the other input stream (?):

gst-launch-0.10 -v videomixer name=mix ! identity silent=false ! x264enc ! mp4mux ! fakesink silent=true   videotestsrc num-buffers=50 ! video/x-raw-yuv,format=\(fourcc\)I420,framerate=\(fraction\)25/1 ! identity silent=true ! mix.    videotestsrc num-buffers=50 ! videorate ! video/x-raw-yuv,format=\(fourcc\)I420,framerate=\(fraction\)25/1 ! ffmpegcolorspace ! identity silent=true ! mix.

When the 'master' stream (the one with the highest framerate) goes EOS, timestamping stops...

    videomixer: fix timestamp problems
    
    When the pad with the highest framerate goes EOS, instead of not timestamping
    output buffers, intepollate timestamps and durations from the last seen ones.
    
    Fixes #608026
