AttributeError: 'UnknownElement' object has no attribute 'MetadataList'

[husnejahan]

Hi,
My code is

import klvdata
import sys

for packet in klvdata.StreamParser(sys.stdin.buffer.read()):
data = packet.MetadataList()

I am getting error as follows:

AttributeError: 'UnknownElement' object has no attribute 'MetadataList'

Any suggestions?

Hi

I don't know what values you have for this sys.stdin.buffer.read(), but clearly packet is null.

Here are some basic examples.

I also recommend that you print your variables or debug your code to see what happens.

Hello,
I am also getting this error when using this code:

import klvdata

def klvparser(srcFileName):
json_dict = {"frames":list()}
with open(srcFileName, 'rb') as f:
for packet in klvdata.StreamParser(f):
metadata = packet.MetadataList()

srcFileName = "stream.klv"
klvparser(srcFileName)

My error is:
line 7, in klvparser
metadata = packet.MetadataList()
AttributeError: 'UnknownElement' object has no attribute 'MetadataList'

the stream.klv file can be downloaded here:

Hi,

I have used the following command to save klv

$ ffmpeg -i udp://localhost:8010 -map 0:1 -f data -codec copy out.klv

then trying to parse.

Looks like the issue was with the klv data itself
