It's not really clear anyone will be able to provide much help here.

Are you checking the pipeline bus for messages? Are there any error
messages? Does the state change for the pipeline to PAUSED complete?

Maybe check the GST_DEBUG log to see what's going on. Start with

 GST_DEBUG=*typefind*:5,*decode*:5

to see if typefinding happens, if a media type is found, and if
decodebin tries to plug parsers/demuxers/decoders.
