[mosquitto-dev] Not receiving large Binary data on websocket (Browser)

I can't receive large binary files in the Browser through websocket.

labtop[192.168.1.158] ==> here I have the browser subscribed to a topic "/VIDEO"

Mosquito Broker[192.168.1.102] 

PC [192.168.1.153] ==> I use this to publish the file

My test was:

1) PUBLISH FILE from PC:  mosquitto_pub -h 192.168.1.102 -p 1883 -t "/VIDEO"    -u test -P '123'  -f video_test.mp4

2) SUBSCRIBE the Browser in my labtop:  _javascript_ subscribe to "/VIDEO"  keep listening for incoming data..

3) TCPDUMP watch something is arrive:    tcpdump  -i wlan0 host 192.168.1.102

    Dump result:

As you can see the packets arrived to the labtop but not ALL. 


Any Idea where can be the problem?


Thank you.
