I terminate gst-launch with ctrl-c but after than i use this pipeline to close
the file:

gst-launch filesrc location=file.mkv ! matroskademux ! matroskamux ! filesink
location=file_closed.mkv

As far as i know this is a good way to closing the output file... Maybe not?
(Your example works for me without any errors, too)

I made some test with the num-buffers property to avoid it, but the result
generates "non-existing PPS referenced" errors, and with 1 fps the results
either can't be playable with gstreamer. (Btw what means exactly this message?
i can't find a proper description about that.) 

Pipeline:
gst-launch lannersrc num-buffers=100 ! capsfilter
caps="video/x-h264,framerate=10/1" ! matroskamux ! filesink
location=10fps_lanner2matroska.mkv

Then i tried reencoding the stream of our capture card, and everything was fine
and seekable:

gst-launch lannersrc num-buffers=20 ! capsfilter
caps="video/x-h264,framerate=1/1" ! ffdec_h264 ! x264enc byte-stream=false !
matroskamux ! filesink location=10fps_reencoded.mkv

Maybe there's a problem with the h264 stream of the capture card?

Tim it would be great a warning message like that.
