Dot graph for playbin2 with missing audio decoder
In Playbin3, negotiation failure is observed if we can not find available audio decoder.
Actually, ACCEPT CAPS query returns 'not accepted' in gstdecodebin3-parse.c
However, In Playbin2, endpad of a chain is not exposed from decodebin when corresponding decoder is missing(e.g. unknown type).
And then, playback works well without unknown audio type.
So, I think it is more better and good to play likes playbin2.
