decodebin "passthrough"?

[Marianna Smidth Buschle]

I haven't tried with real pass-through.

But I had with just demuxing: 'video/mpegts ! decodebin ! video/x-h264'
And that worked fine, so I would expect the h264 pass-through to work as 
well.

Though I'm not sure if the 'decodebin' includes parsers (like 
'h264parse'), so it might do some small modifications to 'stream-format' 
or 'alignment'?
Depending on what is default and what is downstream.

Best Regards
Marianna
