- *
- * This is an AAC parser which handles both ADIF and ADTS stream formats.
- *
- * As ADIF format is not framed, it is not seekable and stream duration cannot
- * be determined either. However, ADTS format AAC clips can be seeked, and parser
- * can also estimate playback position and clip duration.

- * SECTION:element-flacparse
- * @see_also: flacdec, oggdemux, vorbisparse
- *
- * The flacparse element will parse the header packets of the FLAC
- * stream and put them as the streamheader in the caps. This is used in the
- * multifdsink case where you want to stream live FLAC streams to multiple
- * clients, each client has to receive the streamheaders first before they can
- * consume the FLAC packets.
- *
- * This element also makes sure that the buffers that it pushes out are properly
- * timestamped and that their offset and offset_end are set. The buffers that
- * flacparse outputs have all of the metadata that oggmux expects to receive,
- * which allows you to (for example) remux an ogg/flac or convert a native FLAC
- * format file to an ogg bitstream.
- *
- * <refsect2>
- * <title>Example pipelines</title>
- * |[
- * gst-launch -v filesrc location=sine.flac ! flacparse ! identity \
- * ! oggmux ! filesink location=sine-remuxed.ogg
- * ]| This pipeline converts a native FLAC format file to an ogg bitstream.
- * It also illustrates that the streamheader is set in the caps, and that each
- * buffer has the timestamp, duration, offset, and offset_end set.

- * accurate seeks. Currently it can only do a lookup via the convert function,
