For example: This will drop all outgoing HTTP requests containing ".mp4". You can fine-tune it to your needs and to consume less router CPU.

[admin@MikroTik] > /ip firewall filter
[admin@MikroTik] /ip firewall filter> add chain=forward action=drop dst-port=80 pr
otocol=tcp place-before=0 content=".mp4" out-interace=WAN
expected end of command (line 1 column 86)

this shown , nothing happend

Replace WAN with name of your WAN interface in parameter out-interace=WAN.
What version of RouterOS you have?

5.24

I've tested this with 6.26 and it works as expected.

But remember that it only works for HTTP and not HTTPS!

I think he is stuck at WAN renaming...

Maybe in 5.24 there is different syntax? He should update.
