| <p>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.</p> |
| <p>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.</p> |

| 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. |
