e836640bd5 flvmux: Support rollover in timestamp 
For live streams, if we keep the stream for a long time, the timestamp
will be larger than max_uint32. In that case, timestamp should be handled
as a rollover timestamp rather than a backward timestamp.

flvmux: Use the last DTS for the metadata timestamp 
This avoids creating a timestamp regression during a stream.

flvmux: Correct metadata handling in file and stream mode 
In file mode, only push one onMetaData at the start of the stream.

In stream mode, always push complete onMetaData. They get replaced, not
merged.

c28a9d5d9c flvmux: Add encoder metadata to the header 
And also add a property for setting this. By default it has the same
value as the metadatacreator metadata.

Various software is using encoder instead of metadatacreator, others are
using them both for different purposes. As such it's useful to have
support for setting both here.

8cae95a22d flvmux: Don't refuse caps changes after starting to write headers in streamable mode. 
Flv does support changing the stream type and stream properties
after the headers were started to be written, and for example H264
codec_data changes can be supported.

gst_pad_get_current_caps() as the caps can go to NULL in between. Instead just
use gst_pad_get_current_caps() and check for NULL.

element, as different bits of documentation say different
things about whether it should or not.
