--- Comment #12 from Nicola <lists at svrinformatica.it> ---
let me explain with an example, suppose you save a stream with a pipeline like
this:

gst-launch-1.0 souphttpsrc do-timestamp=true location=... ! jpegparse !
matroskamux ! filesink location=/tmp/jpeg.mkv

the resulting muxed file declare 1/1 as framerate in the caps, now try to play
this file (ip is public) with this pipeline:

gst-launch-1.0 souphttpsrc location="http://195.250.34.59/temp/jpeg.mkv" !
matroskademux ! jpegdec ! xvimagesink

you'll see 1 frame per seconds but the file contain more than 1 fps: this
happens with git master, works with 1.4.5

the suggested patch solve the problem and does not store fake informations
inside the muxer
