Before this CL, the following scenario could happen:
- A new input stream is registered to the DefaultVideoFrameProcessor.
- Before the pipeline is reconfigured, a seek is issued andd the
DefaultVideoFrameProcessor is flushed.
- As a result, the new input stream registration is never taken into
account.
As a result:
- If an input stream is registered after the seek (before queueing any
frame), registerInputStream will block indefinitely because
inputStreamRegisteredCondition will be closed.
- If a frame is queued after the seek, it will be linked to the input
stream information of the previous frames.
This CL makes sure that any pending input stream is registered after a
flush.
