validation errors

[Mikl]

Hello,

I am recording video like this
 video: appsrc ! 'video/x-raw-rgb,width=800,height=600,framerate=24/1' !
jpegenc ! matroskamux ! filesink 
  2 subtitles truks: appsrc ! '"text/x-raw' ! matroskamux ! filesink 
Before stop pipeline i am sending EOS:
gst_element_send_event(_pipeline, gst_event_new_eos());
Also trying to send event to close segment, but don`t see it on the bus

Video can be played in VLS, but not in, standard for Windows, Windows Media
Player
Also i can not play video
gst-launch-1.0 filesrc location=C:\\test\\test.mkv ! matroskademux name=mux
mux.video_0! jpegdec ! autovideosink

Bu running validation i have some information about file.

Can you explain me please, what all this errors means?
