Original commit message from CVS: * ext/flac/gstflacenc.c: (gst_flac_enc_write_callback), (gst_flac_enc_check_discont), (gst_flac_enc_chain), (gst_flac_enc_change_state): * ext/flac/gstflacenc.h: Handle non-zero start timestamps correctly, mark header packets as IN_CAPS and print a warning and suggest using audiorate if stream discontinuities are detected. When FLAC supports flushing the encoder somehow this should be done for discontinuities instead. Remove some unused variables from the instance struct.
