gst/real/gstrealvideodec.*: Don't generate an error for occasional decoding errors.
Original commit message from CVS: * gst/real/gstrealvideodec.c: (gst_real_video_dec_chain), (open_library), (gst_real_video_dec_init), (gst_real_video_dec_set_property), (gst_real_video_dec_get_property), (gst_real_video_dec_class_init): * gst/real/gstrealvideodec.h: Don't generate an error for occasional decoding errors. Add max-errors property. Error out when we receive max-errors in a row. Fixes #478159.
