why doesn't qtmux support byte-stream encoding for h264?

Yes, the reason is that data in the quicktime container is stored as AVC
and not as byte-stream.

No, there is no such plan. The solution is to put an h264parse element
between the encoder and in front of the muxer, which should then convert
byte-stream to avc if needed. I *think* in 1.0 encodebin plugs parsers
now, so you might find it actually works with 1.0 already.
