How to combine 2 filters to get HTTP GET and POST in the same command? I have tried but result have been only the first filter part.

HTTP GET Capture filter sudo tshark -i p2p3 'port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420)'

HTTP POST Capture filter sudo tshark -i p2p3 'tcp port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)'

Or is there a way to filter out picture and video content since this is the source of the problem?

What was the combined filter that you tried? If the two filters each worked separately, you should be able to combine them with a logical 'or'.

Now I tested tshark -i p2p3 'tcp port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)' or 'tcp port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)' but this only gives the last filter in the output.

Any comment?

Is there other ways to discard the actual picture/video content?

You can set the -s snaplen parameter to cut the contents of each packet at a particular length. Have a look at the Wiki page for SnapLen for more info.
