c2b649d692 mpeg4videoparse: add config-interval parameter to re-insert config in stream
Add a new config-interval property to instruct the parser to insert
config (VOSH, VOS, etc) at periodic intervals in the stream
(when a GOP or VOP-I is encountered).

Based on patch by <marc.leeman at gmail.com>

Fixes #621205.

00148e3736 mpeg4videoparse: also set short configuration data in codec_data
That is, header configuration may start at Video Object (startcode),
rather than at Visual Object Sequence, which is catered for and parsed,
so let's also take it as codec_data if no more available.

Fixes (remainder of) #572551.

f33344ab0c mpeg4videoparse: don't set an invalid framerate.
When fixed_vop_rate is not set we can not set a framerate based on
vop_time_increment_resolution as it would most likely be wrong.
Don't set any framerate on the caps in that case.

c0ad05cec4 mpeg4videoparse: Use correct values for checking VO startcode.
Fix compiler warning due to condition always being true - since we're
only looking at the final byte of the startcode (not the leading
0x000001), only check for < 0x1f, not < 0x11f

41b65b421b mpeg4videoparse: handle more formats
We only need a Video Object Start code before we can start pushing out data.
Search for this code also instead of only looking for VOS and VOP.
Fixes #572551.

Mark frames as GST_BUFFER_FLAG_DELTA_UNIT when they are not
intra frames
Set the timestamps of outgoing buffers to the buffer in
which the VOP header was found.
Drop incoming data untill configuration is found (by default,
configurable using a property).
Report a 1 frame latency. Fixes #532723.
