gstreamer : record a stream while playing

[Duchassin Frederic]

Hi,


Even with a queue in each branch it doesn't work :

gst-launch-1.0 filesrc location=/home/sefram/TS/4kfile.ts ! queue ! 
typefind ! tee name=t t. ! *queue* ! decodebin ! queue ! kmssink t. ! 
*queue* ! filesink location=/home/sefram/TS/essai.ts
