I'm trying to update an Input MediaLive URL using boto3 in python.
The input is an URL_PULL type (HLS) and is attached to a channel, and I think it's the source of my issue.
account = { all credentials and stuff }
url = 'https://mynew/supercool/hls/playlist.m3u8'
client = boto3.client("medialive",
aws_access_key_id=account['access_key'],
aws_secret_access_key=account['key_secret'],
region_name=account['region_name'])
input_id = 1234567
client.update_input(InputId=input_id, Sources=[{'Url': url}])
The code is working fine, but I get this error, and I don't know how to handle it :
An error occurred (BadRequestException) when calling the UpdateInput operation: You cannot change the input class of an input while it's attached to a channel. Please detach the input from the channel in order to switch its class.
Question : Which workflow should I use to update an input that is already attached to a channel ?
AWS API expects 2 urls when updating an input, main and backup.
client.update_input(InputId=input_id, Sources=[{'Url': url},{'Url': url}])
If the input class is STANDARD_INPUT you will need 2 URLs, but if you are using a SINGLE_INPUT class you only need 1 URL.
If you only need 1 URL you can create the inputs as SINGLE_INPUT but your channel will have to be single (SINGLE_PIPELINE) instead of STANDARD.
Also, single channels are cheaper than Standard ones!
