Solutions

1. Check that the stream resource is open and readable before handing it to the decoder (is_resource() and stream_get_meta_data()['mode'] contains 'r' or '+')
2. Rewind or re-create the stream if it was already consumed by a previous read
3. Catch errors from the underlying source (network, file) that may have closed the stream prematurely
