How to construct the pipeline for hls videos (AES encrypted or not)

[Duncan Palmer]

Hi Silver,

Using uridecodebin is the correct approach here, as you'll need to deal
with dynamic pipeline reconfiguration on bitrate changes, and decodebin
will handle that for you.

Could you run with the GST_DEBUG environment variable set to
'*:2,hlsdemux:7', and post the logs?
