matroskamux doesn't work with smokeenc, please look at the following pipeline:

gst-launch-0.10 -e -v v4l2src ! smokeenc ! matroskamux ! filesink
location=/tmp/a.mkv
Impostazione della pipeline a PAUSED ...
/GstPipeline:pipeline0/GstV4l2Src:v4l2src0.GstPad:src: caps = video/x-raw-yuv,
format=(fourcc)I420, width=(int)640, height=(int)480, framerate=(fraction)30/1
La pipeline è viva e non necessita il PREROLL ...
Impostazione della pipeline a PLAYING ...

/GstPipeline:pipeline0/GstSmokeEnc:smokeenc0.GstPad:src: caps = video/x-smoke,
width=(int)640, height=(int)480, framerate=(fraction)30/1
/GstPipeline:pipeline0/GstSmokeEnc:smokeenc0.GstPad:sink: caps =
video/x-raw-yuv, format=(fourcc)I420, width=(int)640, height=(int)480,

ERRORE: dall'elemento /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Errore
interno nel flusso di dati.

Esecuzione di free sulla pipeline...

if I change smokeenc to jpegenc or ffenc_mpeg4 it works as expected
