Forward port of revision 16113. Fixes a bug in live555 module, that made audio packets (only for audio types that are not supported) being sent to the video decoder. This caused artefacts and segmentation faults in the decoder. VLC core handles the case for codec being not supported just fine, so removed the check for undefined codec.
