Adds some trace points showing input compressed stream or output decoded frame information. Adds an unconditional trace point when streaming starts showing the compressed stream and the decoded frame information. Adds an unconditional trace point at instance closure summarizing into a single line the decoding process (stream information, decoded and output frames number, potential errors observed).
