Action when cue is detected

[pcb105]

I want to perform an action whenever a cue is detected from a UDP stream. I wrote the following code....

import sys
import threefive

if name == "main":
if len(sys.argv) > 1:
for arg in sys.argv[1:]:
strm = threefive.Stream(arg)
SCTE35 = strm.decode(func=print("cue"))
else:
threefive.decode(sys.stdin.buffer)

python3 NodeSCTE35.py udp://:1234

When I run the code.....
Output:
cue

{It then exits when an actual cue happens}

When I run the code without the func=print("cue")
I get the SCTE information printed out each time the UDP stream has a SCTE marker in it.

I would like to perform an action every time I get a SCTE message within the UDP stream.

Any help would be appreciated.

Sorry I figured it out here is code that does what I was asking for.... If anyone cares :)

import json
import sys
import threefive

def add_cue(cue):
print(cue.get())

if name == "main":
if len(sys.argv) > 1:
for arg in sys.argv[1:]:
strm = threefive.Stream(arg)
strm.decode(func=add_cue)
else:
threefive.decode(sys.stdin.buffer)

python3 NodeSCTE35.py udp://:1234

Hey, I'm sorry I didn't see this until now, however that is exactly how you do it. Nice job man.

• You can also do it with a call to decode_next()

import sys
import threefive

def do():
    arg = sys.argv[1]
    with open(arg,'rb',encoding="utf-8") as tsdata:
        st = threefive.Stream(tsdata)
        while True:
            cue = st.decode_next()
            if not cue:
                return False
            if cue:
                print(cue.get())

if __name__ == "__main__":
    do()
