Not able to cast local video file

[jvergara65]

First, thank you for making this available. It is great!
I am having problems casting a video made with my camera to a Chromecast I have (2 or 3 generation) when executing the command:
catt cast output.webm

The error is the following:

Casting local file output.webm...
Playing "output" on "Living Room TV"...
Serving local file(s).
Exception thrown when calling load failed callback
Traceback (most recent call last):
  File "/home/jvergara/.local/lib/python3.10/site-packages/pychromecast/controllers/media.py", line 745, in _fire_load_failed
    listener.load_media_failed(item, error_code)
AttributeError: 'MediaStatusListener' object has no attribute 'load_media_failed'

it looks like a file is not in an native Chromecast format.

when I ran this command ,
mediainfo output.webm

Here is the output:

Can you help me with the steps to make sure that a local video file is playable in this Chromecast I have?

Thanks
