A partial implementation of FrameOstream, using a map between 'shortnames' and LowLevelEncoder objects.
Subclasses must implement makeEncoderForStem(), but do not need to implement writeFrame() or closeStream(). Subclasses may implement setConfigInfo() as needed.

| void LowLevelEncoderMap::closeStream | ( | const std::string & | shortname | ) | [virtual] |
Close and delete the LowLevelEncoder corresponding to shortname.
This means that if additional frames are later sent to that same shortname, then a new LowLevelEncoder object will be created for that shortname (possibly overwriting previous files or output destinations, etc.).
Implements FrameOstream.

Must be implemented by subclasses to return a type-appropriate encoder object.
Implemented in UcbMpegOutputStream.
| void LowLevelEncoderMap::stop2 | ( | ) | [protected, virtual] |
Overridden to destroy our encoder map.
Reimplemented from ModelComponent.

| void LowLevelEncoderMap::writeFrame | ( | const GenericFrame & | frame, | |
| const std::string & | shortname, | |||
| const FrameInfo & | auxinfo | |||
| ) | [virtual] |
Send the frame to the LowLevelEncoder corresponding to shortname.
If no such encoder exists yet, then a new one will be created by calling the subclass's implementation of makeEncoderForStem().
Implements FrameOstream.
