Now that we might be copying out buffer (e.g. downstream don't support video
meta bug we need it) we need to move the EOS handling inside the process
method.
Upon error, the pools might not have been allocated yet, hence we should not
try and flush them (even though we still want to make sure the processing thread
is fully stopped).
If caps are set again, we have a risk od returning from set_format with a
input_state pointing to dead memory. Clearing the pointer after unref fix
this issue.
Uppon certain downstream error, stop() is called without a flush(). This mean that
the streaming thread may still be running even though unlock has been called.
Now calling flush to reset the decoder state if we are processing.
Simplify sub-instanciation by defining an absract type and using subtype
class and instance init callback. This also fixes a bug where the template
pads get initialized too late.

For each videoCdevice probe it input/output capabilities
if it match with video decoder requirement register a new element.
